There is an old saying:
Men are cold and women are hot.
Originated from some ancient books and records [body yin cold, sex yang dry] and other statements.
In fact, the so-called [heat] and [cold] here are not concepts in modern science, so we cannot judge them with evidence-based and realistic thinking.
However, no matter men or women, there are indeed some cold and warm temperature matters that need our attention. After you have seen them, you should be able to understand whether this health care is cold or hot.
Men, frequent hot baths are not recommended.
The best temperature for testis to maintain normal physiological function is 34 C ~ 35 C. The human body will dissipate heat or keep warm through relaxation and contraction of scrotal skin to provide stable and appropriate temperature for testis.
When taking a bath, the water temperature is often above 40 C, always taking a hot bath for a long time, which is really unfavorable to the testicles.
However, the sauna room full of high-temperature water vapor can reach a temperature of more than 70 C. In such an environment, the role of scrotum in regulating the temperature is greatly reduced, which inevitably affects the normal function of testis.
By the same token, it is also important to ensure the health of male genitals not to wear tight and airtight underpants and jeans.
Women, themselves will be more afraid of the cold
Some studies have shown that the body surface temperature of women is generally lower than that of men. Moreover, compared with men, women are more sensitive to temperature changes, which also explains to some extent why women are more prone to cold hands and feet.
Female friends need special attention: hypothyroidism, iron deficiency anemia, vitamin B12 deficiency, diabetes, etc., can also cause fear of cold. At this time, it is best to go to the hospital, let the doctor check clearly the reason, check the possibility of physical abnormalities.
However, generally speaking, women’s hands and feet are cold, and most of them are normal physiological adjustment changes. Drink some hot water, cover your hands with hot water cups, and do exercises. Under the condition of no varicose veins and arterial embolism, properly soak your feet with hot water can be improved quickly.
What is the appropriate water temperature for bathing and washing face?
No matter men or women, it doesn’t matter [cold and hot]. Dr. Clove suggested that the water temperature in the shower would be more appropriate at 37 octaves, which is probably the temperature at which you feel warm and comfortable.
The water temperature is too cold and the washing is uncomfortable and incomplete.
Some people have formed the habit of taking a cold bath. After washing, they do not feel uncomfortable, which is no harm.
The water temperature is too hot to burn easily.
Research data suggest that continuous exposure to 44 C hot water for about 6 hours will lead to burns. When the water temperature is 49 C, it will lead to burns for about 10 minutes.
Especially for middle-aged and elderly friends and friends with diabetes, the skin is not so sensitive to temperature, and more attention should be paid to: don’t burn yourself unconsciously.
The same is true for washing face. People with different skin types and different water temperatures can achieve the best facial cleaning effect.
1. Dry skin
Use cold water. If the skin itself is dry, hot water will clean the grease too thoroughly, which is not conducive to skin care.
2. Oily skin
Use 38 ~ 40C hot water. The temperature is slightly higher than that of the skin surface but it will not feel hot. It can wash off all the grease mixed with dust and oily bacteria, which is good for the skin.
3. Allergic skin
Use warm water close to body temperature. It can avoid further irritation to sensitive skin.
The above principles are applicable to both men and women.
Hot drink temperature, not exceeding 65 ℃
The appropriate eating temperature is 10 ℃ ~ 40 ℃, and drinks and foods exceeding 65 ℃ will burn mucosa.
The International Agency for Cancer Research has also clearly warned that drinking hot drinks above 65 ° C has carcinogenic risks.
This is not to say that hot soup, hot tea, hot coffee and hot water cannot be drunk, but to hope that everyone will get rid of unhealthy eating habits-it is right to like hot tea and hot soup, but not too hot.
Can I have cold water?
Everyone has his own drinking habits. Cold water, warm water and slightly hot water are free to choose which one he would like to drink. There is no fixed answer.
Many people are accustomed to drinking hot water and are very afraid of drinking cold water. However, our bodies are not so fragile. A few mouthfuls of ice water will not reduce the core temperature of our bodies. The so-called claim that drinking cold water will make our bodies [cold] is just speculation and rumors, and there is no definite evidence.
If you feel that drinking too cold will make you uncomfortable, then don’t drink it. If you feel that drinking something cold will relieve the summer heat and satisfy your needs, you will not feel uncomfortable after drinking it, so you can drink it boldly without worry.
The temperature of the air conditioner should be suitable.
No matter men or women, old or young, if the indoor air conditioner is turned on too low, the body’s thermoregulatory center may not be able to adapt for a while, resulting in stuffy nose, runny nose, headache, etc.
Dr. Clove’s advice is:
- The air conditioner temperature is adjusted to 25 C ~ 26 ℃, which is not too cool and saves electricity. Clean the air conditioner regularly, once a year; Reasonable use of humidifiers to keep indoor humidity between 60% and 70%; Remember to open the window for ventilation after turning off the air conditioner.
If a person drinks water, he knows how warm and cold he is.
This sentence is really good.
Understand the knowledge about changes in temperature, and use the appropriate temperature to keep in good health.
