What effect does washing hands without drying water have on the skin in winter?

In winter fire, because the windows are closed and there is no convection in the air, harmful gases such as carbon dioxide and carbon monoxide will continue to accumulate, the concentration will increase and negative ions will decrease. Even healthy people are prone to dizziness, forgetfulness and other discomfort. Indoor humidity is also low. If you stay in a sultry environment, it will make your throat dry and painful. Long-term warm fire also has adverse effects on human skin, which easily leads to dysfunction of sweat glands and sebum secretion, decreased ability of perspiration and detoxification, skin fatigue, allergies, dermatitis and poor blood circulation. Mild people feel tired, dizzy, cold waist, loss of appetite, poor sleep, severe people are prone to catch a cold, and women even have irregular menstruation.

So, how to protect yourself in a fire? Install a ventilator, put a basin of water indoors, or raise some aquatic plants to adjust the indoor humidity. Always open the doors and windows for ventilation. Don't adjust the temperature in the living room and office too high. If you stay in a hot environment for a long time, you should drink at least 8 cups a day, and at the same time pay attention to eating more foods rich in vitamins, such as vegetables and fruits.
