Types of Saunas and Their Health Benefits
Our body is directly connected to environmental factors. The human skin reacts to any change: heat, cold, humidity, climate change. Usually, we attribute negative effects to these factors. The hot summer sun only dries the skin, and we do not notice any positive impact from such heat. But what if we start warming the skin in a controlled way? Then, the results will be quite different. In their approaches, many biohackers use heat therapy — targeted body warming for a specific purpose. This procedure comes from physiotherapy.

Highlights
- Saunas use heat therapy to promote sweating, which helps detoxify the body.
- Traditional Finnish saunas use dry heat and high temperatures for therapeutic effect.
- Infrared saunas penetrate deeper into the skin using light-based heat therapy.
- Steam saunas (or steam rooms) offer moist heat therapy that benefits the skin.
- Combining saunas with cold plunges creates a powerful contrast therapy effect.
What is heat therapy?
Heat therapy is a type of physical therapy treatment. Sources that produce or retain heat include electric current, light, paraffin, clay, compresses, heat pads, and other means. Saunas and steam rooms are modern variants of heat therapy.
Warm-up usually involves the whole body or separate groups of muscles and joints. Heat therapy accelerates tissue metabolism, stimulates blood circulation, and increases the permeability of blood vessels. This approach allows you to eliminate viral and immune diseases faster in medicine. In cosmetology, the effect of heat on the skin gives a slightly different effect.
Heat therapy is most effective for:
- dry, sluggish skin;
- joint problems;
- slow blood circulation in the tissues, edema;
- damaged skin structure.
In these cases, heat therapy will give the best effect. It can also be successfully combined with cryotherapy. This is not difficult, as most devices have heat and cold modes. Heat therapy contributes to the qualitative improvement of the skin, restoring its structure. Warm skin — a favorable environment for the penetration of various substances. So, you can achieve good moisturization by conducting therapy together with hyaluronic acid. Using vitamins — nutrition. They are also used in lymphatic drainage procedures. In general, heat therapy is a real boon for the biohacker. Since athletes, biohackers, and ordinary people often like to go to saunas, we will dwell on this type of body warming in more detail.
Types of Saunas
Traditional Finnish Sauna
Finns have a special attitude towards saunas. For them, it is a temple for the soul, where you can relax and unwind to the fullest. Finnish saunas belong to dry steam rooms — there is very low humidity, but the air temperature is incredibly high, so sometimes an unprepared person can not withstand it.
The essence of the Finnish sauna is that at extreme temperatures (it can reach 100 °C), sweat begins to secrete actively, which then begins to evaporate quickly. As a result, the procedure is therapeutic in nature — slags are eliminated faster.
In addition, the therapeutic effect is produced thanks to the wood in the steam room. To get the maximum benefit, you need to adhere to simple recommendations:
- Do not go into the steam room with metal jewelry — they quickly heat up, which can lead to a burn;
- Hair should be dry; as a result, it can overheat and get damaged. It is necessary to take with you a special cap, which will protect both the hair and the head from overheating and drying;
- Before the steam room, you should take a shower without detergents;
- In the steam room, you should sit or lie on a towel to avoid getting burned on hot surfaces;
- You should not talk in the steam room, and you should breathe through your mouth;
- You should not stay in the steam room for a long time for the first time — 8 minutes will be enough. But you should also be guided by your own feelings — perhaps you need to reduce this time;
- When visiting the sauna, you should not eat too much — just take some herbal tea with you to quench your thirst. Finns also prefer to drink green tea.
It is worth considering that although Finnish saunas are very healthy, they should not be used if you have a high body temperature, infectious diseases, cancer, skin diseases, or bleeding tendencies.
Infrared Sauna
Infrared saunas help to eliminate muscle pain and fatigue in just half an hour. They are good for people who cannot tolerate the high temperatures of a Russian or Finnish sauna. The temperature inside the sauna with infrared radiation does not exceed 50 degrees Celsius — it is easy and pleasant to tolerate at any age.
Infrared radiation warms tissues and organs, increasing blood circulation and sweating. Its health-improving effect is based on the action of infrared (te. thermal) radiation of a given wavelength, verified experimentally. Active sweating reduces the load on the kidneys, helping to remove swelling. Rapid elimination of toxins and training of the heart reduces the risk of heart attack and normalizes blood pressure. Improved blood circulation and elasticity of blood vessels contribute to treating vascular diseases.
If we compare the effects of an infrared cabin sauna with light therapy and a traditional sauna on the body, we should note an enhanced therapeutic effect with a more gentle regime in the first case. In the sauna, the heat acts only on the skin, but here, it acts directly on the internal organs and deep tissues.
Therefore, sweating is 2-3 times more intense, removing 4 times more solid substances, such as fat, cholesterol, lactic acid, slags, toxins, salts of heavy metals, etc. During the session, up to 2400 kcal are burned, which helps to balance the weight.
Since it happens at a comfortable temperature, the skin better tolerates this procedure. The cosmetic effect, as they say, is evident — due to the opening of pores, the removal of toxins from the skin tissues becomes smooth and elastic, and many skin diseases quickly pass “by themselves.”
In addition, cellulite deposits are dissolved and split, and excess fat is removed. Infrared radiation promotes wound healing and skin regeneration after burns, including sunburns.
Steam Sauna
A steam bath is an ancient bathing process where moist steam cleanses and relaxes the body. It traces its origin to the famed Roman baths or the Turkish ‘Hamam.’ Also known as steam rooms or wet saunas, steam saunas are warm rooms with thick, billowing fog. These saunas are typically built with materials that can handle high humidity and heat levels, such as non-porous tiles, glass, and acrylic. Such materials can help create a tight seal to prevent moisture from escaping while retaining heat.
Modern steam baths are enclosed spaces or small rooms filled with moist steam created by a steam generator. The steam mist is sprayed through special nozzles in the room. Steam saunas typically have a temperature range of 50-60 degrees and a humidity level of a whopping 100%.
Benefits of Sauna Therapy
As you have realized, the sauna is an opportunity to rest and relax and a helpful procedure that effectively affects all body systems. What exactly does sauna therapy provide?
- Respiratory system. Gradual warming helps fight colds and chronic diseases. Blood supply is improved, and respiratory rhythm is stabilized.
- Cardiovascular system. When heating, the pulse rate increases, and blood vessels expand. When cooling, the opposite process occurs. The alternation of these phases is an excellent workout for the heart muscle and a way to stabilize venous pressure and lymphatic exchange.
- Kidneys. Stimulation of the kidneys, as well as other systems, has a positive effect on their functioning. At the same time, it is essential to replenish the lack of fluids promptly.
- Blood pressure. Proper attendance and alternation of warming and cooling stabilize both high and low blood pressure.
- Muscles. Saunas relieve tension, and athletes actively use them. Warming up helps improve flexibility.
- Immunity. The procedure strengthens immunity in general and stimulates the synthesis of interferon, the primary tool in the fight against infections and viruses.
- Pregnancy. In dosed quantities and under the control of specialists, a sauna helps to facilitate labor in pregnant women by reducing muscle tension and positively stimulating the nervous system.
A regular but deliberate visit to the sauna improves general well-being, gives energy and vigor, tones the whole body, and provides relaxation. It is even indicated for some nervous disorders, chronic fatigue, stress, and sleep disorders. A renewed state gives strength for further accomplishments.
Relaxation during a rest in the sauna has an important effect. Relax not only the muscles of the body but also the face. It is useful for the general tone and condition of all who wish to preserve their beauty and youth as long as possible. Also, saunas offer main health benefits.
Improves Cardiovascular Health
Your heart pumps faster during a steam sauna to compensate for what your body releases. Research shows that this increases the amount of blood flowing throughout your system, which may help prevent cardiovascular disease and other chronic health conditions like high blood pressure and type 2 diabetes, explains UCLA Health.
Better Skin Health
A steam sauna session can work wonders for your skin health. When this soothing, warm heat permeates your skin, it can help unclog your pores and release trapped sebum — an oily substance that can cause breakouts and inflammation — so you may have clearer, even-toned skin. Cleveland Clinic mentions that this can be especially beneficial for oily or acne-prone skin.
This increased blood flow during a steam sauna has been shown to promote collagen and elastin production, keeping skin firm, youthful, and wrinkle-free. Research also shows that sauna-induced sweat can improve the skin’s permeability, allowing better absorption and efficacy of skincare products.
Sinus Relief
If you’re tired of using over-the-counter medications, nasal sprays, and allergy drops, a steam sauna can help you breathe easier. A 2017 study published in the Indian Journal of Critical Care Medicine indicates that breathing in moist air moisturizes airways and thins out mucus, offering much-needed relief for sinusitis and nasal congestion. Beyond that, Medical News Today mentions that steam saunas offer exceptional respiratory health benefits, helping relieve the symptoms of allergies, colds, and flu.
Workout Recovery
One common aftereffect of strenuous exercise is delayed-onset muscle soreness (DOMS), a feeling of discomfort and pain that typically begins 12 to 24 hours after a workout and can linger for a few days. If you are looking for a gentle way to accelerate recovery, a steam sauna can help. Research shows that increased circulation during sauna sessions delivers vital nutrients and oxygen to your tired muscles, helping speed recovery.
Stress Reduction
Stress can have detrimental effects on our health, leading to various issues such as digestive problems, heart complications, hypertension, and sexual dysfunction, notes the Mayo Clinic. One way to cope with stress is using a steam sauna. Research shows that when body temperature increases during sauna bathing, cortisol levels drop, alleviating stress and anxiety symptoms.
The high heat during steam sauna sessions also triggers the release of endorphins — the body’s natural feel-good hormones. Healthline explains that these neurotransmitters help you feel happier and more relaxed so that you can take on the world with a positive attitude.
Loosens Stiff Joints
Prolonged sedentary periods, excessive physical exertion, and poor posture can all lead to joint stiffness. The good news is steam saunas can help. The Arthritis Foundation notes that when your body acclimates to sauna temperatures, your blood vessels expand. Studies show that this vasodilation process stimulates nutrient delivery and helps flush out metabolic waste, alleviating inflammation and joint stiffness.
A 2013 study also found that heat therapy significantly enhanced muscle and connective tissue flexibility. This improved flexibility can help reduce joint stress and increase range of motion and physical performance, which can be especially beneficial for athletes and those leading an active lifestyle.
Promotes Weight Loss
If you want to shed a few pounds without racing through the block or hopping on the treadmill, consider steam sauna bathing for weight loss. During a steam sauna session, your body works harder to lower its core temperature. Harvard University explains that this process accelerates your metabolic rate, helping you burn more calories and fat.
Biohacks with Saunas
Using saunas goes beyond simple relaxation — they can be powerful tools for optimizing health, performance, and mental clarity. Here are four science-backed ways to take your sauna sessions to the next level:
Contrast Therapy
Alternate between heat and cold exposure — typically a sauna session followed by an ice bath or cold shower. This contrast stimulates circulation, supports lymphatic drainage, reduces inflammation, and boosts physical and mental stress resilience. It’s also a great way to train your vagus nerve and enhance recovery.
Sauna + Fasting
Engaging in a sauna session while fasting can accelerate autophagy, the body’s cellular cleanup process. The combination may enhance mitochondrial health, increase growth hormone levels, and support longevity. Just stay hydrated and listen to your body, especially during extended fasts.
Infrared Sauna with Salt Therapy
Combine the deep-penetrating heat of infrared saunas with the respiratory benefits of halotherapy (salt therapy). This pairing promotes detoxification and skin health, improves breathing, and reduces symptoms of asthma or allergies. Think of it as a dual detox: inside and out.
Incorporate Breathwork & Meditation
The sauna’s heat naturally encourages introspection and calm, and the effect can be amplified by adding conscious breathwork or meditation. Try box breathing, alternate nostril breathing, or guided visualization to lower cortisol levels, improve focus, and deepen the parasympathetic (rest-and-digest) state.
What You Need to Know Before Using Saunas
Saunas offer incredible benefits, but to get the most out of your sessions — and stay safe — there are a few key things to remember. From timing and preparation to avoiding common risks, here’s what you need to know.
What to Do Before, During, and After
Before:
- Hydrate well — drink plenty of water or add electrolytes.
- Avoid heavy meals and alcohol.
- Take a quick shower to remove any lotions or oils.
During:
- Start slow — begin with 10–15 minutes if you’re new.
- Listen to your body; dizziness or nausea is a sign to stop.
- Sit or lie down comfortably, and focus on your breath.
After:
- Cool down gradually — don’t shock your system.
- Rehydrate and replenish minerals (e.g., magnesium, sodium, potassium).
- Take a contrast shower or cold plunge if using contrast therapy.
Optimal Time and Temperature for a Session
- Traditional saunas (dry or steam): 15–20 minutes at 160–200°F (70–90°C)
- Infrared saunas: 25–45 minutes at 120–150°F (50–65°C)
The optimal frequency is 2–4 times a week, though seasoned users may go more often. The key is consistency over intensity.
How to Mitigate the Risks
- Stay hydrated: dehydration is the most significant risk. Drink water before and after, and consider adding electrolytes.
- Know your limits: avoid saunas if you’re pregnant, have uncontrolled heart issues, or have low blood pressure — always consult a healthcare provider.
- Avoid overuse: too much heat can lead to fatigue, electrolyte imbalance, or skin irritation. More isn’t always better.
- Use caution during fasting or illness: fasting intensifies the detox response, so monitor your energy levels closely.
To sum up
Sauna is a treatment method in a wooden room dried at a high temperature and has many benefits. First, going to a sauna can reduce stress levels; the high temperature helps combat stress by relaxing muscles and creating an overall feeling of relaxation. It can also reduce muscle tension and relieve pain. A sauna helps deliver more oxygen and nutrients to the body’s tissues by increasing blood circulation. Speeding up the sweating process also helps to eliminate toxins from the body.
It can stimulate the immune system and keep the heart healthy. Saunas are also effective in skin care and can improve skin tone by clearing the pores. However, it should be noted that some people may be harmed by sauna use. It is especially important to consult a doctor for those who suffer from heart disease or have serious health problems. Drinking enough water and not exceeding the recommended time are also important rules for safe use.
