Although summer sauna may seem contradictory to high temperature environments, reasonable use may still bring certain benefits, but it needs to be combined with personal constitution and scientific methods. The following are the potential benefits and precautions of summer sauna:
Potential benefits
Promote sweating and detoxification
The high temperature in the sauna room stimulates sweat gland secretion, helping to eliminate excess water, salt, and small amounts of metabolic waste (such as urea and lactate) from the body. In summer, the human body sweats more, and saunas may accelerate this process. However, it is important to replenish water and electrolytes in a timely manner to avoid dehydration.
Blood Circulation
Under high temperature conditions, blood vessels dilate and blood circulation accelerates, which may help alleviate muscle tension and reduce fatigue. For people who sit for long periods of time or exercise, saunas may promote lactate metabolism and relieve soreness.
Relax and relieve stress
The warm environment of sauna can stimulate the secretion of endorphins, bring a sense of relaxation, and help alleviate anxiety caused by high temperatures or work in summer. Some people believe that it is similar to "thermal therapy" and has a certain auxiliary effect on improving sleep quality.
Cleaning pores and skin care
High temperatures cause pores to dilate, which may help remove dirt and excess oil from the surface of the skin. However, it should be noted that after sauna, the skin is in a sensitive state and needs to be cleaned and moisturized in a timely manner to avoid clogged or dry pores.
Enhancing immunity (controversial viewpoint)
Some studies suggest that moderate heat stress may activate the immune system, but this conclusion is still inconclusive. The immune enhancement effect of summer saunas may not be as significant as in winter, and excessive heat should be avoided to avoid burdening the body.
Precautions and Risks
Dehydration and electrolyte imbalance
In summer, the human body is prone to sweating, and saunas can exacerbate water loss. Drink plenty of water (with a small amount of salt or electrolyte beverages added) before and after the sauna to avoid dizziness, fatigue, and even heatstroke.
Cardiovascular burden
High temperatures can cause increased heart rate and blood pressure fluctuations. Patients with cardiovascular disease, hypertension, or the elderly should use it with caution to avoid inducing discomfort.
time control
It is recommended to shorten the summer sauna time to 5-10 minutes to avoid prolonged exposure to high temperatures that can cause heat stroke or skin damage.
individual difference
People who are sensitive to heat, physically weak, or suffer from skin diseases such as eczema and dermatitis may not be suitable for sauna and need to adjust according to their own situation.
environment selection
Ensure good ventilation in the sauna room to avoid air pollution that increases respiratory burden. After finishing, do not immediately enter the air-conditioned room or take a cold shower. Wait for your body temperature to naturally decrease.
scientific advice
Frequency: 1-2 times a week is recommended to avoid frequent use.
Time: Choose a cooler time in the morning or evening, and avoid high temperatures at noon.
Matching: After sauna, you can do light stretching or cold water wiping (not showering) to promote the circulation of blood vessel contraction and relaxation.
Taboo: It is not advisable to take a sauna after drinking alcohol, on an empty stomach or when full.
Summary: Summer sauna may bring temporary relaxation and sweating benefits, but it is necessary to strictly control the time, replenish water, and be alert to potential risks. If you pursue similar effects, you can also choose warm water showers or moderate exercise as alternatives, which are safer and more suitable for most people.
