Bathing time depends on the water temperature, especially for people in poor health. Many people can't soak in hot water above 40℃ for a long time. Soak at water temperature above 42℃ for 3-5 minutes, at 40℃ 10 minute, and at 37℃ to 39℃ for 20-30 minutes.
People in poor health should try not to soak in water when taking a bath. Measurements show that when an adult lets hot water reach his shoulders, the water pressure of his whole body will reach about 500 kilograms. This may make people feel uncomfortable in the heart and lungs, and the body is also burdened. You can soak your body in your ribs and keep your heart and lungs out of water. The heating effect of water temperature can stimulate the "continuous circulation in the body" system and promote blood circulation. Hot water can also promote sweat to be discharged from pores together with waste in the body, which has a cosmetic effect on the skin.
A healthy person can immerse himself in water when taking a bath. The displacement of the body makes him lose weight, reduce muscle tension, relax physically and mentally, and improve his sleep.
So when is the best time to take a bath?
1, 7: 30 in the morning-get up and take a shower.
Taking a bath for 5 minutes after getting up can help people's brains and organs get up quickly, so that even if they sleep for a short time on the first night, they can be refreshed all morning.
Note: Because the body's protection is weak, the body surface lacks protection at night, and moisture can easily enter the body, so it is not too late to take a bath at night.
2. Take a bath 2 hours before going to bed
People who have the habit of taking a bath before going to bed should finish it 2 hours before going to bed. Two hours before going to bed can not only wash away the fatigue of the day, but more importantly, it will not affect sleep.
Because drowsiness often occurs after the body temperature drops, hot water bath will raise the body temperature and delay the release of "sleep hormones" by the brain. Therefore, if you want to fall asleep quickly, you'd better not take a bath before going to bed, but two hours in advance.
If you must take a bath before going to bed, you can cold compress your forehead with a wet towel for 5 minutes after taking a shower to let your body temperature drop to normal level before going to bed.
