Saunas have been around for thousands of years and continue to be popular. They are now commonplace in many cultures, from Finnish outdoor saunas to Swedish batsu, Korean jjimjilbangs, and Japanese sento.
Saunas and steam rooms are designed to increase sweating using distinct types of heat. Saunas employ dry heat from a stove or hot rocks to raise the room’s temperature to 195°F (90.5°C) with extremely low humidity. Steam rooms, on the other hand, use wet heat. They function at lower temperatures, often between 110 and 120°F (43 and 49°C) and relative humidity of 100 percent.
Nothing is more reviving physically than a daily deep, healthy sweat. You emerge mentally calm, revitalized, and prepared for whatever the day may bring. Numerous studies show that a deep, healthy sweat alleviates stress, decreases muscle tension, and promotes an overall sensation of relaxation and well-being. This is why a growing number of physicians are recommending sauna therapy due to its purifying characteristics.
Saunas have long been used to induce a state of relaxation. Your sympathetic nervous system becomes more active to help maintain your body’s temperature equilibrium. Your endocrine glands become activated in response to this stimulus. Your body’s response to heat can reduce your pain sensitivity, increase your alertness, and give you a sense of elation. As a result of the heat, your muscles relax, particularly those in your face and neck. These muscles are frequently stiff following a long day.
Saunas may also benefit people who suffer from chronic pain or arthritis. For four weeks, a study found that sauna sessions relieved pain, stiffness, and exhaustion in persons with chronic musculoskeletal disorders such as rheumatoid arthritis and ankylosing spondylitis.
The sauna’s heat relaxes you and balances the level of cortisol in your blood. Cortisol is the stress hormone, and having too much cortisol can result in a range of health problems, including the immune system and sleep disorders. Sauna bathing decreases cortisol levels in the blood while increasing serotonin synthesis. Serotonin is your “happy hormone,” or the chemical that makes you feel good.
A sauna’s ability to reduce stress levels may reduce cardiovascular risk. For two decades, one research in Finland tracked 2,315 men aged 42 to 60. According to the findings, sauna users may lower the risk of dying from cardiovascular disease.
Studies have found that sauna use is associated with fewer fatal cardiovascular-related disorders. Sauna use on a more frequent basis reduces the incidence of sudden cardiac death by 22 percent compared to those who used it only once a week. Sudden cardiac death was 63 percent less likely in those who used a sauna four to seven times a week, and cardiovascular disease mortality was 50 percent less likely in those who used a sauna once a week.
The heat of a sauna causes the core body temperature to rise. Sweat is produced primarily to cool the body and is 99 percent water. However, thorough sweating in a sauna can assist in lowering levels of lead, copper, zinc, nickel, mercury, and chemicals – all of which are toxins that are routinely acquired via regular interactions with your environments. Sweating can also assist in pore cleansing, which may result in your skin appearing more clear following a sauna session.
Sauna use has been demonstrated to result in a deeper, more calm sleep. Along with the release of endorphins, body temperatures rise in the late evening and decline at bedtime. This gradual, soothing drop in endorphins is critical for sleep facilitation.
