Sunbathing is a hardening method that helps strengthen the immune system and increase resistance to viruses. They are very useful for those who often suffer from various diseases. Baths are recommended after breaks in an active lifestyle, training and physical work. The procedure helps improve the condition of the musculoskeletal system, improve the functioning of the cardiovascular and respiratory systems, and reduce the risk of skin diseases. Sunbathing is not recommended during periods of extreme heat, sandstorms or severe thunderstorms. The duration of water procedures may vary depending on the indications. At the same time, experts exclude strong exposure to the sun, which doctors and trainers rarely warn about.
