Once you feel unwell, the method of inviting someone to take a bath in the morning is different. When you want to wake up in the morning, you can take a shower with hot water of about 42℃, or let the hot water soak around your shoulders. Joint and muscle activity is relatively slow in the morning. To improve this, you can use a slightly warmer bubble.

You don't need to wash your body after taking a bath. When you use a bathing agent with moisturizing effect, it is best not to take a bath at last. Just like soaking in a hot spring, it will wash away the moisturizing ingredients left on the skin surface. However, if you put grapefruit and calamus, etc. It should be noted that there may be skin irritation and need to be rinsed off.

Be sure to eat first and then take a bath. No sooner had a person finished eating than a lot of blood flowed into his stomach. If you take a bath just after eating, hot water will make people's blood flow to the skin, causing stomach ischemia and indigestion. If you take a bath on an empty stomach, it is easy to cause dizziness and nausea, which is very harmful to your body. Experts suggest that it is best to take a bath two hours after meals.

Bathing is no substitute for bathing. With the increase of age, blood circulation and metabolism will gradually decrease.

I hope everyone can get rid of the cold for a day by taking a bath, and don't let the cold accumulate in the body.

The bathing time should be controlled in warm water of about 38-40℃. When soaked in warm water, it takes about 1 minute for blood to circulate to the whole body. And let our body warm up from the inside out, this process needs at least 20 blood circulation, which means that about 20 minutes of bathing time is the most appropriate.

People with hay fever and allergies, especially those who are allergic to bathing or have dry skin, may be worried that bathing will cause itchy skin. However, a warm half-length bath that can raise the body temperature inside the body will not cause itching, but also improve immunity and remove allergic substances attached to the skin. In addition, when the body of pollinosis patients is cold, the symptoms will be aggravated, and half-body bath can also be used to improve the problem of chills and reorganize the melancholy mood caused by pollinosis.

Most people think that hot water is the most effective way to promote blood circulation, relieve fatigue and relax, especially in cold winter.

2. Eliminate edema of legs and feet: soak in warm water at 37℃ 10 minutes or more, and the water level should not exceed the legs. In addition to promoting blood circulation through warm effect, blood and lymph gathered in the legs can also be brought to the upper body through long-term water pressure circulation.

3. Stabilize mood: soaking in hot water below 40℃ 15-20 minutes can make the sympathetic nerve in a state of mental and physical tension become a parasympathetic nerve with calming effect.

4. Improve rough skin: Hot water will dry the skin, and long-term bathing will reduce the skin's defense function. So choose warm water at 38-40℃ and soak for 5 minutes. What is important is the subsequent peeling step.

5. Relieve muscle fatigue: soak in hot water above 39℃ 15 minutes or more to promote blood circulation. Only when the blood circulation is smooth can lactic acid, a substance that causes fatigue, be transformed into an energy source.
