Cholesterol is an essential lipid for the human body, but when its levels are imbalanced, especially when low-density lipoprotein cholesterol (LDL-C) and triglycerides (TG) are elevated, the risk of cardiovascular disease increases significantly.
Therefore, effectively regulating blood lipid levels has always been a core topic in the field of health management. In recent years, in addition to traditional dietary control and exercise intervention, people have begun to pay attention to some auxiliary health methods, such as sauna therapy, especially steam sauna rooms, to see if they can play a role in improving blood lipids and lowering cholesterol.
This article will explore this issue in depth from multiple perspectives, including basic knowledge of cholesterol, the physiological mechanism of action of steam sauna rooms, scientific research results, possible pathways of action, suitable and cautioned populations, and how to scientifically use steam sauna rooms to assist in blood lipid management.
What are cholesterol and blood lipids?
1. Types of Cholesterol
Cholesterol comes in several different types, each with different functions and health implications:
• Low-density lipoprotein cholesterol (LDL-C): Commonly known as "bad cholesterol," high levels can deposit on the walls of blood vessels, forming atherosclerotic plaques.
• High-density lipoprotein cholesterol (HDL-C): Commonly known as "good cholesterol," it helps transport excess cholesterol back to the liver for metabolism.
• Total cholesterol (TC): Includes LDL, HDL, and other forms of cholesterol.
• Triglycerides (TG): Another form of blood lipid; high levels are also closely related to cardiovascular risk.
2. Dangers of Elevated Cholesterol
When LDL-C and TG levels remain high for a long period, it accelerates the process of arteriosclerosis, increasing the risk of diseases such as myocardial infarction and stroke; while low HDL-C also weakens the reverse cholesterol transport capacity.
3. Common Interventions
• Dietary management: Reduce the intake of saturated fatty acids and trans fatty acids, and increase dietary fiber.
• Regular exercise: Combine aerobic exercise with strength training.
• Drug treatment: Such as statins and fibrates.
• Lifestyle interventions: Including quitting smoking, limiting alcohol consumption, and improving sleep patterns.
What is a steam sauna room?
A steam sauna room is a closed space that uses high-humidity steam (relative humidity close to 100%) for full-body heat therapy. Compared to dry saunas, steam sauna room temperatures are typically around 40℃–50℃, but the humidity is extremely high, making the perceived temperature even higher.
What are the main effects of a steam sauna room?
1. Promotes blood circulation: Heat stimulation dilates blood vessels, increasing blood flow.
2. Increases sweating: Profuse sweating removes metabolic waste.
3. Accelerates metabolism: Increased body temperature can temporarily increase the basal metabolic rate.
4. Relaxes muscles and relieves tension: The high-humidity environment helps relieve muscle soreness and mental stress.
Can a steam sauna room lower cholesterol?
Based on existing research, sauna therapy may help lower low-density lipoprotein cholesterol (LDL-C) and triglycerides (TG), and increase high-density lipoprotein cholesterol (HDL-C). This change has positive implications for the prevention of dyslipidemia and cardiovascular disease.
Furthermore, the study also found that:
• By increasing heart rate, enhancing blood flow, and promoting metabolism, a steam sauna room can mimic some of the physiological responses of low- to moderate-intensity aerobic exercise;
• When combined with dietary control and regular exercise, a steam sauna room may play an additional role in reducing body fat and improving body composition, thereby indirectly affecting blood lipid levels;
• Long-term regular use may have a more significant effect on improving blood lipids, but it needs to be combined with other health interventions.
Possible Mechanisms By Which a Steam Sauna Room Affects Cholesterol
1. Increased Metabolic Rate
In a steam sauna room, the body's core temperature rises, the sympathetic nervous system is excited, heart rate increases, and metabolic levels rise in the short term. This extra energy expenditure helps reduce body fat reserves, thereby affecting cholesterol synthesis and distribution.
2. Improved Blood Circulation
The high-temperature and humid environment promotes vasodilation and faster blood flow, which is beneficial for cholesterol transport and clearance, especially enhancing the reverse transport function of HDL-C, transporting LDL-C from the blood vessel walls back to the liver for metabolism.
3. Promotes Hormone and Enzyme Activity
Thermal stimulation can affect the activity of various metabolism-related enzymes, such as lipoprotein lipase (LPL), which helps in the breakdown and metabolism of triglycerides and may also promote the liver's processing of cholesterol.
4. Reduces Chronic Inflammation
Chronic low-grade inflammation is an important factor in atherosclerosis. Steam sauna rooms help reduce the level of inflammatory mediators by promoting blood flow and improving circulation, thereby indirectly improving blood lipid levels.
The Adjunctive Role and Limitations of Steam Sauna Rooms in Blood Lipid Management
1. Adjunctive Role
• Can be part of a healthy lifestyle, working in conjunction with diet and exercise;
• Plays a supporting role in weight management, indirectly affecting cholesterol levels;
• Helps improve cardiovascular function and vascular elasticity, thereby affecting blood lipid metabolism.
2. Limitations and Precautions
• Cannot replace diet control and exercise: Steam sauna rooms alone cannot significantly improve severe dyslipidemia;
• Effects vary from person to person: Genetic factors, metabolic characteristics, and frequency of use can all affect the results;
• May not be suitable for certain groups: such as patients with severe heart disease, acute infections, or skin diseases.
Steam Sauna Room: Suitable and Cautionary Users
1. Suitable Users
• Individuals with mild dyslipidemia and no serious cardiovascular disease;
• Individuals who wish to improve their health through relaxation and metabolic support;
• Users as part of a comprehensive health management program.
2. Users requiring caution or avoiding use
• Individuals with severe heart disease or unstable angina;
• Individuals with high fever, acute infections, or severe skin diseases;
• Individuals with low blood pressure or prone to fainting;
• Pregnant women and individuals with certain special medical conditions (consult a doctor).
Suggestions for the Scientific Use of a Steam Sauna Room to Assist in Cholesterol Management
1. Usage time and frequency
• 10–20 minutes per session is recommended, adjusted according to individual tolerance;
• 2–4 times per week is appropriate; avoid overuse.
2. Hydration and electrolyte replenishment
• High humidity and heat can cause excessive sweating; replenish fluids before and after use;
• Pay attention to electrolyte balance during prolonged or frequent use to prevent hyponatremia.
3. Integrate with Lifestyle
• Combine with a low-saturated-fat diet and regular exercise;
• Avoid use after drinking alcohol to prevent excessive cardiovascular burden.
In short: Based on current scientific evidence, steam sauna rooms may play a supporting role in lowering LDL-C and TG, and increasing HDL-C. This effect mainly comes from its mechanisms of boosting metabolism, promoting blood flow, regulating the activity of lipid metabolism enzymes, and reducing chronic inflammation.
