Unlike a bath, a sauna envelops the entire body, from head to toe, in high heat. The human brain, in particular, is more than half fat and is vulnerable to heat; overheating can lead to a feeling of being dazed, which causes lightheadedness. Therefore, people who are not accustomed to heat cannot fully enjoy the sauna. By covering the head and ears with a sauna hat, you can reduce the likelihood of lightheadedness. 2. Prevents hair dryness. The temperature in a sauna room is generally around 80°C to 90°C, and can reach 100°C in a hot sauna. Therefore, parts of the hair, which are vulnerable to heat, can be significantly damaged. Dry hair can withstand heat up to about 180°C, but wet hair is more susceptible to heat damage. In particular, repeated exposure to temperatures above 100°C can easily create voids in the hair, leading to dryness. 3. Protects the scalp and ears. ✅4 [Packed with Convenient Features] ● Hanging hook for convenient washing and storage ● Large pocket for storing small items ● Deep-fitting type that blocks the view ● Reversible type with changing design and color 【 Product Specifications 】 ● Size: Height 26cm x Head circumference 58cm ● Color variations: Beige x White, Gray x Black
