Although taking a hot bath has many advantages, it also has problems. If you take a hot bath on an empty stomach, it is easy to cause hypoglycemia and even faint. Taking a hot bath immediately after a meal will concentrate a lot of blood on the body surface, which is not conducive to the digestion and absorption of food. If you take a hot bath in a public bathhouse, it will be harmful to your health, because there are more bacteria in the public pool.
Some bathing methods are wrong, such as: using overheated water; Wash repeatedly with soap; Rub your skin with a rough towel. Excessive water temperature will burn the skin, accelerate skin aging, and also cause heatstroke reaction; Washing with soap too many times will reduce the skin's defense ability; Rubbing the skin with a rough towel will accelerate the keratinization of the skin and even cause various skin diseases.
Taking a hot bath will speed up the blood circulation of the body and increase the burden on the heart. Therefore, the elderly, children, patients with heart disease and cardiovascular and cerebrovascular diseases should take warm baths instead of hot baths.
