It is very hot in summer, and many people will take a cold bath to cool off. Taking a cold bath can relieve summer heat and enhance immunity, which is called "vascular gymnastics". After continuous exercise, you can take it not only in summer but also in winter. But taking a cold bath has steps and taboos to avoid causing physical discomfort.

When taking a cold bath, the skin surface will turn white due to the contraction of cold water before 1 to 2 minutes, and blood will flow to the depths of internal organs. But after washing for 2 to 3 minutes, the blood will be redistributed, the blood will flow back to the skin surface, and the skin will gradually turn red. The whole process is like doing vascular gymnastics.

First, get used to taking a cold bath. It's best to start exercising in summer, and take a cold bath in winter when your body can adapt.

Warm up first

Like exercise, you should warm up before taking a cold bath. You can make your body move, or rub it for a few minutes to make your skin a little red and hot, or you can do a massage while rubbing.

It shouldn't take long.

The whole process from taking a cold bath to taking a cold bath can't last too long, 10 minutes or so, and the longest is not more than half an hour. If you often take a cold bath and are in good health, you can use the three-temperature method of alternating cold and hot, and the effect will be better, but you must try it in good health.

Keep warm after washing

In addition to taking a cold bath for a long time, wrap a bath towel or put on a bathrobe immediately after washing, and put on clothes to keep warm immediately to avoid catching a cold.

Rinse the limbs first.

In order to let your body adapt to cold water slowly, you should take a cold shower before soaking. When rushing, you should also pay attention to starting from your hands, feet and limbs for a few minutes, and then rushing to your chest. Don't be too irritating to your body.

You can add essential oil.

It is best not to take a cold bath for more than 5 minutes, and you can add some essential oil when taking a bath. Dr Andy Sun said that he personally likes to add a little mint to completely relax his body. After taking a cold bath at night, he can go to bed immediately and sleep soundly.

If you feel uncomfortable, don't stop.

When taking a cold shower, if you feel shivering with cold, your skin is turning white and dizzy, stop immediately and don't try to be brave.

Pay more attention

Taking a cold bath is good for your health, but not everyone can try it. Don't take a cold bath in the following situations, and it's cold in winter. Unless you are used to taking a cold bath or you are strong, don't try it easily.

Cold bath taboo

hypertension

When you have symptoms of high blood pressure such as neck pain, dizziness and headache, don't take a cold bath, because when you take a cold bath, blood vessels will contract rapidly and your blood pressure will soar.

heart disease

When taking a cold bath, blood rushes to the heart, which will make the heart unable to load. People with poor liver, kidney and lung function are also not suitable for taking a cold bath, because their organs may not be able to load.

Drink wine

After drinking, the skin pores are fully open, and when taking a cold shower, it will shrink rapidly due to cold water, and the impact is too great for the body to bear.

After strenuous exercise

When you engage in strenuous exercise, just like drinking, you will sweat and get hot, so that the pores of your skin will be fully opened, and taking a bath immediately will make your body unbearable.

insufficiency of Qi and Blood

During menstruation, pregnancy and confinement, women are weak, lack of qi and blood, and poor blood circulation, so they are not suitable for taking a cold bath for vascular gymnastics.

I just had enough.

When eating, blood will flow to the stomach to help the food digest. If you take a cold bath immediately, it will make blood flow from the stomach to other internal organs of the body and affect digestion. It takes half an hour to take a cold bath after dinner.

out of sorts

If you have a cold, a fever or any inflammation, you are not feeling well. Because you are weak, you are not suitable for taking a cold bath.

There are many benefits

Not easy to catch a cold

People who often catch a cold and have poor immunity can take more cold baths to increase their cold tolerance and enhance their immunity. In addition, blood will flow to internal organs, which can take out visceral toxins and promote visceral metabolism.

Help sleep and soothe nerves.

Faster heartbeat and dry mouth can lead to autonomic nerve disorder. Taking a cold bath can make the autonomic nerves not excited, which is helpful to sleep and soothe the nerves.

Help digestion.

Taking a cold bath can promote gastrointestinal peristalsis and improve digestive function, but don't take a cold bath within half an hour after meals, so as to avoid the rapid outflow of blood from the stomach and cause indigestion.

The skin is elastic.

Taking a cold bath often can make blood flow to subcutaneous tissue, making skin softer and more elastic.
