First, taking a bath for too long will destroy the cuticle of the skin. When taking a bath, people's skin is soaked in water for a long time, and the water in the skin will evaporate, which is most likely to lead to dehydration of the skin. In the long run, the skin will become dry. Moreover, the water looks clean, but it actually contains a lot of bacteria and microorganisms, which will lead to allergic symptoms on the skin, because it is necessary to grasp the time when taking a bath.
Second, there are many toxic gases in the water, so it is not advisable to take a bath for too long. Tap water contains toxic gases such as chloroform and trichloroethylene. When taking a bath, these toxic substances enter the human body with water vapor and participate in blood circulation, which will cause sudden fainting. If you take a bath in the bathtub, there is no one around, and the consequences are unimaginable.
Third, taking a bath for a long time will cause hypoxia in the brain. Bathing is a physical activity, although bathing can accelerate metabolism, but overwork will only be counterproductive. Bathing actually consumes human body heat, and it also consumes glucose in the blood, leading to hypoglycemia. Taking a bath for a long time can also lead to hypoxia in the brain. Because of the increase of water vapor, the air in the bathroom will gradually decrease, and at the same time, the temperature is high and the oxygen supply is insufficient, which leads to dizziness and chest tightness.
