Spending time in a steam room can be a refreshing experience, especially when the temperature sits between 40 to 50 degrees and the humidity is close to 100%. Your body responds in some fascinating ways. For instance, this environment can help lower muscle tension, boost blood flow, open up your airways, and allow your skin to retain more moisture.

Just sitting in a warm room and sweating might seem pretty straightforward, but internally, your body is quite busy. Your heart rate starts to mimic what it feels like during light exercise, and blood vessels widen to help with circulation. Alongside that, your stress hormones drop while those feel-good endorphins increase. This chain reaction explains many of the positive feelings people get from steam bathing.

If you’re curious to experience these benefits, TH7 Body Labs offers steam rooms at our studios in Brisbane and the Sunshine Coast as part of our recovery services.

How a steam room works

Exploring the workings of a steam room can help explain the benefits of moist heat. Inside a steam room, water vapour saturates the air, leading to an atmosphere of almost complete humidity. This high moisture content stays in the air instead of evaporating from your skin, which distinguishes steam rooms from saunas (which use dry heat).

When you step into a sauna, the dry air causes sweat to evaporate swiftly from your skin, which results in a cooling sensation. On the other hand, a steam room envelops you in warm, humid air, keeping the moisture on your skin. This prevents evaporation, so your body temperature increases faster. As a result, steam rooms often feel hotter, despite having lower actual temperatures compared to saunas. Saunas usually run at temperatures from 80 to 100 degrees Celsius with low humidity. In contrast, steam rooms are set at about 40 to 50 degrees Celsius but with nearly complete humidity.

The variation in humidity affects not only your perceived temperature but also has other effects. The humidity found in a steam room helps relieve your air passage, and the warmth will affect your body in different ways. The moisture makes muscles feel relaxed compared to when there is dry heat.

Steam room vs sauna: the difference between moist heat and dry heat 

Both steam rooms and saunas effectively increase your body temperature and have a similar impact on your cardiovascular system. However, how they manage to do so differs immensely.

Dry heat created by either hot rocks or infrared rays in a sauna causes the air around to heat up. As a result, your body sweats, and evaporation of sweat causes your body to cool down. This reaction usually causes a very sharp sensation on your skin and is good for various health reasons.

Steam rooms create a humid environment by using moist heat, which keeps your skin damp and warm since sweat doesn’t evaporate quickly. This allows the heat to seep into your skin and tissues at a slower pace. The moisture-rich air can be beneficial for your lungs, as it helps to soften mucus, easing your breathing. This gentle warmth tends to be soothing, making steam rooms a preferred choice for people dealing with respiratory problems, dry skin, or stiff joints, and anyone with sensitive systems.

Neither one has a clear advantage over the other since each type fulfils certain requirements. Depending on your individual health priorities and how you are feeling on any particular day, your preference could differ. More information can be found in our comparison of steam rooms and saunas.

What happens to your body in the first 15 minutes

In just a matter of minutes, your skin temperature increases as your body starts absorbing the heat. Your blood flows toward the surface of your skin to assist in cooling, which causes your blood vessels to expand. Your heart rate increases by 20 to 30 beats per minute, which is equivalent to a brisk walking pace.

By the time you reach five minutes, your sweat glands are fully active. Your breathing becomes slightly slower as the humid air helps your airways relax. Meanwhile, your cortisol levels begin to decrease, signalling the start of stress reduction.

As you continue to the 10 to 15-minute mark, your parasympathetic nervous system transitions into a recovery mode. Here, muscle tension eases, offering your body a passive cardiovascular workout that also promotes relaxation. Around this time, most people begin to feel a sense of mental calm. This feeling is due to the release of endorphins and beta-endorphins, coupled with the reduction in stress hormones, providing both physical and mental relief.

The benefits of steam for muscle recovery after exercise

After a tough workout, steam can be an excellent aid for muscle recovery. The moist heat penetrates both muscle tissue and connective tissue, boosting blood flow to deliver more oxygen and nutrients to tired muscles. This increased circulation helps clear out training byproducts like lactate and inflammatory markers more efficiently. 

Steam’s heat also calms the nervous system by decreasing muscle spindle activity, which contributes to the relaxed sensation. When muscles are warmed with moist heat, the tightness signals diminish, making it similar to how a sauna aids recovery after intense exercise.

Reducing delayed onset muscle soreness (DOMS) with steam

DOMS usually starts between 24 and 72 hours post-exercise and is caused by small tears in the muscles’ fibres and the resulting inflammation, creating the typical feeling of tightness. A steam bath cannot cure DOMS completely, but it can help make it less intense and shorten its duration. The increased circulation in the problem areas helps to clear away inflammatory toxins more quickly while supplying more repairing elements to the muscles.

Additionally, heat treatment can decrease the sensitivity of pain receptors in muscles. According to a 2021 meta-analysis of 32 studies, heat application within an hour after exercise significantly reduces DOMS pain.

A combination of steam baths and active recovery is practised by athletes at TH7’s studio on the day following intensive training due to their muscles being in relaxed states.

Loosening stiff joints and improving flexibility

Heat will make the elasticity of the connective tissues (tendons, ligaments, and fascia) better, meaning that these tissues become more flexible and can easily stretch. Flexibility is one of the major benefits of steam therapy, as well as the increased ability to move your joints through a full range of movement. This becomes even more important when you have chronic stiffness due to arthritis, repeated exercise, or simply because of accumulated tension over time. However, stiff joints do not occur alone; the associated muscle tissue, tendons, and fascia are also involved.

Steam therapy lasting 15 minutes (along with mobility activities) will prove more effective than just doing mobility exercises in cases such as the hips, shoulders, lower back, and thoracic area.

Why moist heat preserves muscle strength better than dry heat

In terms of recovery, steam beats out dry heat. Although it is true that a dry sauna may be hard on the skin (as well as possibly diminishing muscle strength because of the thermoregulatory efforts being exerted by the body), steam is a milder choice. Since there is no high air temperature present, and the moisture content in the air makes it easier for heat to enter into the body, muscle tissues become warm but free from the discomfort of dry heat.

Studies have found out that moist heat travels faster through tissues compared to dry heat, while providing similar results in pain reduction and muscle strength maintenance.

The result? After a steam session, you will be refreshed and rejuvenated, but not tired out like you might be after an extended dry sauna session.

How heat exposure improves cardiovascular health

Heat therapy is one of the most extensively studied natural ways to improve cardiovascular health. Being exposed to heat for a certain period of time causes physiological reactions that are very similar to those induced by physical exercise. Heart rate increases, blood vessels dilate, and cardiac output becomes more efficient. Repeated heat exposure leads to adaptations that improve endothelial cell efficiency and responsiveness in the blood vessels.

This effect isn’t limited only to steam rooms. The same effects are seen in response to heat therapy conducted in other ways. This explains why the use of heat baths can lead to such a wide variety of health improvements that go beyond recovery of muscle tissue.

How heat dilates blood vessels and improves blood flow

When your body gets warmer, it kicks into gear by expanding the blood vessels near your skin to help cool you down. This process, called vasodilation, also occurs in the vessels that supply blood to your muscles and organs.

As these blood vessels widen, they allow more blood to flow with less pressure. This improved flow ensures that oxygen and nutrients reach your tissues more efficiently, while waste products are removed more swiftly. This enhanced nutrient delivery system is one of the reasons why a person who has had a hard time working out feels refreshed after exercising.

Frequent exposure to heat can also make your blood vessels adapt in such a way that they work better. This is one reason why individuals who regularly visit saunas have better blood circulation than people living sedentary lives.

What the research says about steam rooms and blood pressure

The heat inside the steam room may result in a considerable change in a person’s blood pressure. While sitting in the steam room, the heat makes the blood vessels dilate, leading to a temporary drop in blood pressure. Some people experience dizziness when they get up from the steam room because of this. For people who visit the steam room regularly over several weeks and months, there are studies that indicate minor drops in blood pressure levels.

Research by The Journal of Physiology in 2016 demonstrated that exposure to heat through hot water immersion for two months contributed to improvement in blood vessel health, reduction in arterial stiffness, and decrease in blood pressure among physically inactive individuals. There may not be many studies carried out on steam baths, but their effect seems similar to that of the Finnish sauna.

However, it is vital to note that despite the health benefits associated with steam rooms, they cannot be used to substitute any medication or other recommended changes by your physician. If you suffer from high blood pressure or are taking blood pressure medication, it would be advisable for you to seek the advice of a medical practitioner before incorporating steam room therapy into your routine.

Respiratory benefits and easier breathing

One unique quality of steam rooms is the effect on your respiratory system. In contrast to dry heat, you will be enveloped in an environment that will keep your respiratory system hydrated from nose to lungs. This will reduce mucus buildup and ease inflammation, enabling easier breathing. Individuals with asthma, sinus problems, and allergies can instantly experience this advantage. Even people who do not have any respiratory health problems can experience deep and slow breathing, which adds to the overall calming effect of a steam session.

Clearing sinus congestion and loosening phlegm

Sinus congestion often results from inflammation and thick mucus in the nasal passages. Warm, humid air can help alleviate these issues. The moisture loosens mucus, allowing it to drain more easily, while the warmth reduces inflammation in the nasal lining. A short steam session of 10 to 15 minutes can clear stubborn congestion. Breathing slowly through your nose rather than your mouth enhances this effect, and gentle nasal exhales might reveal blockages you didn’t realise were there. This is similar to using steam inhalation for colds, but on a larger scale.

Steam therapy for asthma, colds, and seasonal allergies

For those with asthma, moist air can soothe irritated airways and lessen dryness that may trigger symptoms. However, some individuals find heat can be a trigger, so it’s essential to pay attention to how you react, starting with short sessions. Colds and allergies often respond well to steam, as both involve inflamed and congested airways. While steam doesn’t cure colds faster, it can provide symptom relief. A 2017 review examined the use of heated humidified air for colds and found mixed results; some experienced relief, while others saw no clear improvement. Allergy sufferers often appreciate how steam clears post-nasal drip and relieves the head pressure associated with pollen.

If you have a fever or feel particularly unwell, it’s best to skip the steam room. Heat exposure can drain your energy further when your body is already fighting an infection.

Skin health and hydration

Steam plays an important role in promoting healthy skin in two different ways. Firstly, since steam is warm, its condensation on the skin leads to moisturisation of the outermost layer. In addition, the heat generated facilitates better blood flow, thereby increasing a supply of nutrients and oxygen to the skin cells responsible for regrowth. Over time, these processes lead to moisture retention, smoother skin tone, and the removal of dead cells.

Opening pores, sweating, and clearer skin

While pores don’t actually “open and close” like some marketing claims suggest, they do slightly dilate with heat. This dilation facilitates the removal of sweat and trapped oils. Sweating then helps eliminate dead skin cells, surface oils, and environmental pollutants that accumulate throughout the day. The result is clearer skin achieved without the need for harsh exfoliation. A quick 15-minute steam session, followed by a gentle rinse, often leaves skin feeling softer and more refreshed.

For those struggling with active acne, it’s important to avoid touching the face during steaming sessions and to rinse with lukewarm water afterwards. Hot water can irritate already sensitive skin. There’s more on the things at play in our deeper look at steam room benefits for skin.

Why steam improves skin hydration in dry climates

The Australian weather can be harsh on your skin. The dry air, high sun exposure, and the constant use of air-conditioning can dehydrate you, and even in regions such as Brisbane and Sunshine Coast that normally receive high levels of humidity, the changing weather may still result in dehydrated skin. Steaming reverses this effect by creating a humid atmosphere in which moisture enters your skin instead of leaving it. The heat temporarily makes your skin more porous, allowing deeper hydration than surface-level moisture alone can provide.

For people living in drier areas of Queensland (or for those who have been spending long periods indoors in air conditioned environments), steaming regularly can help combat these problems to an appreciable degree. People generally find that after a few steaming sessions, their skin is well hydrated, especially in those areas of the body that tend to suffer from being dry.

Managing acne and breakouts through steam therapy

Acne develops due to the presence of too much sebum, clogged pores, bacterial infection, and inflammation. Steam therapy may solve the problem of sebum and clogged pores since it breaks down sebum and unclogs the pores, allowing the sweat to remove oils and dead skin cells. However, steam therapy does not tackle the problem of bacteria or inflammation; it only serves as an add-on method in treating acne rather than a main remedy for the problem. People with oily or clogged skin might benefit from using steam therapy as part of their skin care regimen.

Stress reduction and mental well being

People come back to steam rooms repeatedly due to the dependable stress relief that they offer. This is not an illusion but rather something real and biological. The exposure to heat causes the nervous system to become calm and relaxed, causing a decrease in the levels of cortisol and the production of feel-good chemicals. That’s what makes you feel lighter and more relaxed after emerging from a steam room.

Lowering cortisol and triggering endorphin release

Cortisol, the body’s main stress hormone, can have a significant impact on your sleep, mood, weight, and immune function if it remains high for too long. During heat exposure, this hormone level drops, and the effect can last for hours. Additionally, the experience triggers the release of beta-endorphins, which naturally elevate your mood. This combination of reduced cortisol and increased endorphins results in the peaceful, uplifted feeling many people associate with a steam room session. It’s similar to the mood boost after exercise, but in this case, you get to relax while it happens.

With regular use, these benefits can multiply. Many who incorporate steam sessions into their routine report better sleep, lower stress levels, improved mood, and an enhanced overall sense of well-being. It’s a practical way to manage stress and anxiety naturally, without turning to medication.

Building steam into a weekly self care routine

To make the most of steam rooms, consider incorporating them into your weekly routine. A couple of sessions per week is a good starting point. Healthy adults can enjoy even more, especially if they pair it with cold therapy or an active recovery routine. However, more isn’t always better, and the benefits may level off after a certain point.

To maximise effectiveness, try to schedule your steam room visits around activities you already do. For instance, you might enjoy a steam session after a workout or before settling in for a quiet evening at home. Some people make it part of their Sunday reset, while others fit it in during the middle of the week between intense training days. By treating steam sessions as a regular part of your self-care routine rather than an occasional luxury, you can truly reap the ongoing benefits. Typically, a session lasting 15 to 20 minutes is just right for most people. Longer sessions don’t necessarily mean more benefits.

Immune support and the body’s natural detox response

When your body is exposed to heat, it induces a small level of stress. If this stress is handled properly, it causes adaptation, which helps in boosting your immunity in the long run. There have been cases where people using steam baths and saunas have claimed to have fewer respiratory illnesses and improved immune response.

In fact, a 25-year study found out that people doing heat treatment four times or more in a week were 41% less likely to have respiratory illnesses than those who practised it once a week or less.

White blood cell production and immune response

While you are in a steam room, your body temperature will be raised for a short period of time, mimicking the early stages of having a fever. This triggers the production of white blood cells, which helps in fighting off diseases. Being in the heat regularly is known to trigger the release of heat shock proteins, which help in repairing and protecting cells. These factors explain why people who take saunas or steam baths are less likely to get sick. The key lies in consistent use, which gradually fortifies the immune system rather than offering immediate dramatic changes.

What “detox” actually means in a steam room context

The word “detox” is widely misused by wellness practitioners, frequently in an exaggerated fashion. The liver and kidneys are the main organs that filter out waste products and toxins from the body. Although the steam room cannot be used to perform these crucial functions in place of the liver and kidneys, it helps increase perspiration, which results in the removal of toxins such as heavy metals and Bisphenol A (BPA). Most importantly, the steam room improves circulation to support the work of the liver and kidneys. For a deeper dive into these mechanisms, check out our guide on supporting your body’s natural detox processes.

Who should avoid a steam room?

Although steam rooms are beneficial for almost all healthy people, there are certain individuals who shouldn’t consider going to a steam room.

Medical conditions that make steam rooms unsafe

A major contraindication would be a pregnant woman. High body temperature in pregnant women can cause complications. They should avoid entering the steam room without consulting their obstetrician.

Patients with cardiovascular problems such as unstable angina, acute myocardial infarction, advanced heart failure, and uncontrolled arrhythmia should not enter the steam room, either. The same applies to severely uncontrolled high blood pressure or low blood pressure. Steam rooms cause significant cardiovascular shifts and should not be used by anyone whose system can’t handle that load safely.

Other medical conditions warranting caution include epilepsy or any seizure disorder, severe respiratory conditions like advanced COPD, active infections with fever, and any condition affecting your ability to sweat or regulate temperature. Children under 12 generally shouldn’t use steam rooms because their thermoregulatory systems aren’t fully developed.

When to check with a healthcare professional first

If you take medications that affect blood pressure, blood thinning, heart rhythm or hydration, talk to your doctor before regular use. Diabetes, particularly with autonomic neuropathy, also warrants a conversation, since impaired temperature regulation and altered sweating can change how your body responds to extreme heat.

Recent surgery, ongoing cancer treatment, major chronic illness and significant immune compromise are all worth discussing with your healthcare professional first. The conversation isn’t about getting permission. It’s about understanding how your particular body will respond.

How to get the most from a steam room session

Adjusting a few simple habits can significantly enhance your steam room visits. These changes focus more on how you prepare and pace yourself rather than the actual time spent inside.

Session length, hydration, and what to do before you step in

For most people, spending 15 to 20 minutes in the steam room is ideal. If you’re new to this, start with 10 minutes and gradually increase your time. Longer sessions don’t necessarily offer more benefits and can leave you feeling drained. For a detailed breakdown, you can refer to our guide on how long to spend in a steam room.

Before stepping into the steam room, drink about 500ml of water within the preceding half hour. Steam sessions cause significant fluid loss through sweating, and entering a session dehydrated can be taxing instead of refreshing. Sipping water during your session is also a good idea. Steer clear of alcohol beforehand, as it can worsen dehydration, raise your heart rate, and increase the risk of feeling unwell.

Have a light snack at least an hour before your session. Entering the steam room on an empty stomach might cause dizziness, while a heavy meal just before can divert blood towards digestion when your body needs it for regulating temperature.

Taking a quick warm shower before entering the steam room can wash off oils and allow the steam to penetrate your skin more effectively. Avoid a hot shower right before, as it adds unnecessary strain on your cardiovascular system.

Pairing steam with cold therapy, sauna, or massage for deeper recovery

Combining different recovery methods can amplify their benefits. Each technique offers unique physiological effects, and using them in a strategic order deepens recovery.

The most popular combination is steam, followed by a cold plunge. This contrast between heat and cold stimulates your blood vessels to dilate and constrict, which helps pump your lymphatic and circulatory systems. Typically, people enjoy 15 minutes in the steam, followed by 1 to 3 minutes in the ice bath, repeating this cycle two or three times. This approach, known as contrast therapy, boosts circulation and speeds up recovery.

Pairing steam with a traditional sauna provides both respiratory and skin benefits from the moist heat and cardiovascular conditioning from the dry heat. You might spend 10 minutes in the steam room, then 15 in the sauna, with a cool rinse in between. If you’re adding cold therapy, the order is important; our guide on sauna and ice bath sequencing offers insights on effective combinations.

Using steam before a massage can soften muscle tissues, allowing the massage to be more effective and less uncomfortable. Many therapists notice a significant difference when clients steam beforehand.

These combinations form the backbone of our recovery protocols at TH7. Our studios are equipped to offer these sessions in sequence under one roof, which is why our methods often yield more profound results than using a single technique alone.

Common mistakes that cancel out the benefits

Many people miss out on the benefits of a good steam session by making a few common mistakes. One of the biggest errors is arriving dehydrated. After sweating profusely during a workout, some individuals head straight into the steam room without hydrating. This leads to a depleted nervous system, lingering fatigue, and minimal recovery. It’s crucial to drink water before and after, and sipping some during the session can also be beneficial.

Another mistake is staying in too long. People often think that the longer they stay, the better the effects. But beyond 20 or 25 minutes, the body’s stress response becomes counterproductive, leaving you more exhausted than rejuvenated.

Rising too quickly is also a problem. The heat dilates blood vessels and lowers blood pressure, so standing up too fast can cause dizziness or a head rush. It’s better to move slowly and sit for a moment before walking out.

Other pitfalls to avoid include drinking alcohol before or after the session, eating a large meal beforehand, entering with broken skin or fresh tattoos, tensing your shoulders throughout, and skipping the cool-down. Cooling down, whether through a cool shower, a swim, a brief cold exposure, or simply sitting quietly, helps solidify the session’s benefits by signalling to your nervous system that it’s time to relax.

FAQs

How often should you use a steam room?

The answer here would be two to four times a week, although you could use the steam room daily if you are adequately hydrated and able to recover between each session. Once you go beyond four or five sessions, the gains from the steam become more marginal.

Is a steam room or sauna better for muscle recovery?

When it comes to muscle recovery, steam rooms often have the upper hand. The moist heat in a steam room offers a gentle, even warmth that can soothe muscles without the intense dry heat that saunas provide. If you’re focusing on cardiovascular benefits or enhancing heat shock protein production, saunas may be more beneficial. For the best recovery results, consider alternating between the two, incorporating cold exposure to maximise the benefits.

Can you use a steam room every day?

Yes, as long as you remain hydrated, limit your time to less than 20 minutes, and listen to your body. People who use steam rooms daily say they experience improved sleep and reduced stress, but those with heart problems or who feel fatigued need to go easy and consult their physician. Our piece on whether you should use a steam room every day goes deeper on the trade-offs.

Does a steam room help you lose weight?

Yes, you will sweat in the steam room, causing you to lose weight. However, this weight is lost temporarily because it will be regained when you drink fluids. You will also burn about 100 to 150 calories while using the steam room (an equivalent to walking at a moderate pace) depending on duration, but they’re not a tool for fat loss on their own.

Should you shower before or after a steam room?

Both. A brief warm shower before entering will remove excess oils on the skin and make it easier for the heat from the sauna to penetrate your skin. Taking a cool or lukewarm shower afterwards is also recommended to wash away the sweat.

Can you use a steam room when you’re sick?

If you are running a fever or feeling under the weather, avoid going to the steam room. The additional stress on your body from the heat will increase exhaustion levels and intensify your illness. If you are just mildly congested or recovering from a cold, then it is probably safe for you to use the steam room.
