Why are there differences in bathing frequency between southerners and northerners?
The frequency of bathing in the south is higher than that in the north. Taking a bath every day is a habit of many southerners, and the reason for this difference is related to the environment. The climate in the north is dry, cold in winter and dry in summer, while the climate in the south is humid, and people sweat more in winter and summer. Therefore, southerners must take a bath every day, otherwise it will be very uncomfortable.
Who takes a bath every day or only once a week is better?
Some people must take a bath every day. If they don't take a bath, they will be uncomfortable. Some people take a bath once a week. It's cool after every bath. If you want to know which of these two people is healthier? It also needs specific analysis of specific problems, which varies from person to person.
If you sweat every day and your skin is oily, then it is no problem to take a bath every day. If it is dry skin, the problem of sweating is not serious. Taking a bath too often every day will destroy the skin barrier and make the skin drier.
However, if you take a bath once a week in summer, substances such as sweat and dust secreted by the human body attached to the skin will continue to ferment and react, which will eventually stimulate the skin to feel uncomfortable and produce odor. In this case, people who bathe every day are naturally cleaner and better able to protect skin hygiene than those who bathe once a week.
Although bathing seems to be a very common thing, if it is not well washed, there will still be certain health risks. Pay attention to some matters and details when taking a bath, and don't let your health be threatened. What should I pay attention to when taking a bath?
Don't take a bath when you are hungry.
Because the heat transfer of water is 26-28 times that of air, the human body will consume a lot of heat in the process of bathing. According to experiments, when a person 12 years old, staying in water for 4 minutes consumes the same amount of heat as staying in air at the same temperature 1 hour. So people are very tired after taking a shower, which is related to this. Most of the calories consumed by the human body are obtained through the oxidation of glucose in the blood. When the human body is hungry, the blood sugar level is always low, which can not meet the requirements of energy consumption. Therefore, when taking a bath on an empty stomach, it is easy to cause dizziness and even syncope and shock due to hypoglycemia.
Pay attention to the temperature in the bathroom
When people take a bath, the temperature in the bathroom is higher than that in other rooms due to the influence of hot water. Being in a high temperature environment for a long time will make people feel uncomfortable, and there will be problems such as lack of oxygen, dizziness and difficulty breathing. Control the time when taking a shower. Don't stay in the bathroom for long. It's best to open the window for ventilation.
The temperature of the bath water should not be too hot or too cold.
Excessive bath water temperature can easily cause vasodilation in the body, affect the blood supply and oxygen supply to the heart and brain, and lead to hypoxia and other problems. Taking a cold bath is easy to cause vasoconstriction and high blood pressure, which is also very dangerous to the human body.
Don't take a bath after drinking.
Don't take a bath after drinking. If you take a bath after drinking, it will lower people's blood pressure, promote the absorption of alcohol, and even cause heart disease or stroke. Don't take a bath when you are tired. Taking a bath at this time will easily lead to insufficient blood supply and make people collapse.
Don't take a bath for too long
Because the soaking time is too long, the skin capillaries dilate, and the blood flows to the body surface too much, which disturbs the distribution balance of human blood and causes cerebral ischemia and dizziness, especially in patients with hypertension and coronary heart disease. For health, take a bath for about 20 minutes, not more than 30 minutes.
To sum up, taking a bath once a week or once a day depends on people's skin condition. No matter what kind of bathing frequency you choose, the one that suits you is the best.
