Which is Better: Sauna or Bathing?

Sauna and bathing are two common ways to maintain health. Bathing is generally used for beauty or fatigue relief, which is a form of showering. It is necessary to control the bathing time and water temperature to reduce irritation to the skin and facilitate blood circulation as well as relaxation. Sauna, on the other hand, utilizes high temperatures to promote sweating and expel coldness and toxins from the body through pores, making it suitable for people with cold constitutions.

1. Bathing

Bathing is a form of showering where the body is immersed in water. According to human physiology, 40℃ is an important threshold. Water temperatures ranging from 37℃ to 39℃ have less irritation on the skin, and at this temperature, the parasympathetic nervous system can help relax the body and mind. When bathing, you can choose bath salts containing vitamins, minerals, essential oils, and other additives. The duration of bathing should be determined based on the water temperature, especially for those with poor health conditions. Hot water exceeding 40℃ should not be soaked in for a long time. Water temperatures above 42℃ should be soaked for a maximum of 3-5 minutes, 40℃ for 10 minutes, and 37℃ to 39℃ warm water for 20-30 minutes.

2. Contraindications of Bathing

For those with poor health conditions, it is recommended to avoid immersing the entire body in water when bathing. According to measurements, when an adult immerses their body in hot water up to their shoulders, the water pressure exerted on the body can reach approximately 500 kilograms, which may cause discomfort to the heart and lungs and impose a burden on the body. Instead, it is advisable to immerse the body up to the ribcage, leaving the heart and lungs exposed. The heating effect of the water temperature can stimulate the "homeostatic" system and promote blood circulation. Hot water can also help expel sweat and waste from the body through pores, exerting a beneficial effect on the skin.

3. Sauna

Sauna is a recreational activity that originated in Korea and has a long history. It is deeply loved by the people and is a significant feature of Korean culture. Traditional Korean saunas involve heating yellow mud and various stones, while people sit or lie down to expel wind, dispel coldness, warm the body, promote blood circulation, and enhance skin beauty. Sauna rooms can range in size from 3 square meters to 100 square meters, with smaller ones accommodating only one person and larger ones seating or lying down up to 70 people. In ancient times, it was a privilege enjoyed only by the nobility or royalty, reflecting its deep cultural origins. With the popularity of Korean culture, sauna has also followed Korean dramas, fashion, makeup, and beauty techniques into China. In just a few years, it has quickly gained recognition and acceptance among Chinese people and gradually become a new and popular way to maintain health.
