Is it better to take a bath with hot water or cold water?

Once the hot summer comes, we need to take a shower every day. So some people not only take cold showers to cool down, but also take cold showers for convenience. This will have a certain impact on our hot body. Some people like to take a shower but ignore the consequences, which may cause some physical reactions in the future. Now let’s take a look at whether it is better to take a bath with hot water or cold water.

1. What is the appropriate temperature of bath water: The temperature of bath water should be close to body temperature, that is, 35-37°C. If the water temperature is too high, it will cause the epidermal blood vessels throughout the body to dilate, reduce heart and brain blood flow, and cause hypoxia. Pregnant women should be careful not to use too high a water temperature when bathing to prevent fetal hypoxia and affect fetal development. Take cold showers in moderation in summer. Bathing water that is too cold will cause the skin pores to suddenly close, the blood vessels to suddenly contract, and the heat in the body to be unable to dissipate. Especially on hot nights, taking a cold shower often makes people feel weak in the limbs, sore shoulders and knees, and abdominal pain, and can even be a triggering factor for arthritis and chronic gastrointestinal diseases. Generally speaking, the water temperature for taking a cold shower in summer should not be lower than 10℃.

2. You should not take a bath after a full meal or when you are hungry. When you take a shower after a full meal, the hot water will stimulate the blood vessels throughout your body to dilate, causing more blood to flow to the body surface. The blood supply to the abdominal cavity will be relatively reduced, which will affect digestion and absorption, causing hypoglycemia, and even collapse and fainting.

3. You should not take a bath after drinking. Alcohol inhibits liver activity and hinders the recovery of glucose in the body. When taking a bath, the body's glucose consumption will increase. If you take a shower after drinking alcohol, your blood sugar won't be replenished in time, which can easily cause dizziness, blurred vision, and general weakness. In severe cases, you may even suffer from hypoglycemia and coma.

4. You should not take a shower immediately after work. Whether it is physical labor or mental labor, you should rest for a while before taking a shower, otherwise it will easily cause insufficient blood supply to the heart and brain, or even fainting.

5. You should not take a bath when your blood pressure is too low. When the water temperature is too high, people's blood vessels dilate, and people with low blood pressure are prone to temporary cerebral ischemia and collapse.

The above briefly introduces the question of whether it is better to use hot water or cold water for bathing. There are many similar problems in our lives, but how to solve these problems is when we should be careful. In order to increase our body's resistance and immunity, we need to develop good living and eating habits.
