Absolutely do not bathe at these 4 times

Here are 4 times when you should not take a bath, no matter how dirty, to protect your health.

1. Just waking up
Many people think that taking a bath right after waking up will help the body wake up and have a day full of energy. However, taking a bath right after waking up is not a good choice for health.

After a night's sleep, the body is in a state of relaxation and rest, blood circulation is slower, heart rate and blood pressure are relatively lower. If you take a bath right after waking up, especially a hot bath, it can cause blood to flow quickly to the skin surface, while the amount of blood supplied to internal organs such as the brain and heart is reduced. This change can cause dizziness, fatigue and even fainting in people with large fluctuations in blood pressure.

In addition, the morning is the time when blood sugar levels in the body are lower, especially for people who eat dinner early or do not eat at night. Bathing in this situation, especially hot water baths, can reduce blood sugar and increase the risk of hypoglycemia.

Therefore, after waking up, you should wait for your body to gradually adapt to the state of being awake or exercise, and then take a bath.

2. Just had a full meal
Many people have the habit of bathing right after eating. However, after eating, the digestive system needs a large amount of blood to help the digestive tract absorb and digest food.

If you bathe right after eating, the change in water temperature will cause blood to flow to the surface of the body, affecting the blood supply to the digestive tract, thereby adversely affecting the digestion process. This can lead to problems such as indigestion and bloating, and may even affect digestive health in the long term.

Especially after eating foods rich in fat and protein, the digestion process is more complicated and requires more blood supply. Therefore, you should wait at least 30 minutes to 1 hour after a meal to wait for the food to be initially digested before bathing to avoid putting a burden on the digestive system.

3. Take a late bath and go to bed immediately
People should not bathe after 10 pm. Because if you bathe with hot or cold water during this time, the body will constrict or dilate blood vessels to retain or release heat. This can easily cause sudden blood vessel spasms, making the body susceptible to high blood pressure or even stroke.

In addition, you should not sleep immediately after bathing. Bathing too close to bedtime, especially hot baths, will cause the body temperature to increase, and the human body needs to lower its body temperature when falling asleep to achieve the best sleep state.

From a physiological perspective, the human body needs a lower body temperature to promote the secretion of melatonin, an important hormone that regulates sleep. Therefore, you should shower 1 to 2 hours before going to bed so that the body has time to gradually return to the appropriate sleeping temperature. In addition, the water temperature should not be too high to avoid stimulating the nervous system and making people more alert.

4. After exercise
After exercise, the body will sweat a lot, many people want to shower immediately to remove sweat, helping the body clean.

However, during exercise, the heart rate and blood pressure will increase, blood flow increases rapidly and the body will be in a state of "fight or flight" excitement. Showering right at this time, especially cold showers, will cause blood vessels to suddenly constrict, affecting blood circulation and can cause cardiovascular problems, even stroke.

In addition, after exercise, the body needs time to detoxify through sweat and dissipate heat through the skin to regulate body temperature. If you take a bath immediately, especially a hot bath, it can interrupt the body's natural cooling process and increase the burden on the cardiovascular system. Therefore, after strenuous exercise, you should cool down and rest properly so that your heart rate and body temperature gradually return to normal before bathing.
