The temperature is getting colder day by day.

When the temperature drops, it becomes a difficult season for people with poor circulation.

In particular, isn't your body getting cold quickly even though you've warmed up in the bath, and your feet are too cold to sleep when you go to bed?

I'm cold, so I try to keep the bath cool by following the method I was taught when I was a kid.

The method is a cold shower after taking a bath.

The reason why the body gets cold quickly even though it warms up in the bath is that the blood vessels that have expanded due to the warming in the bath continue to release heat because they continue to expand after the bath. ..

Therefore, by taking a cold shower after taking a bath, the widened blood vessels are contracted, and the heat inside the body is tightly confined and the warm state continues.

The feeling of cold water is quite different between when you really take a cold shower and when you don't.

I want you to try the cold shower from tonight.

It is important to take a cold shower after taking a bath and warming up to the core of your body.

At first, take a shower that you think is cold from your feet far from your heart. Put it on your entire leg, then put it on your arm from the fingertips of your hand.

I think you can feel a change in the feeling of cold water with just your legs and arms.

If you bathe in cold water all at once on a cold day, your heart will be surprised, so it may be better to gradually get used to it with a little lukewarm water.

However, if you apply cold water for too long, the blood vessels will contract too much and the core of your body will cool down. You can feel the warmth just by cooling the surface.

Also, taking a cold shower will increase corticosteroids. It is said that an increase in corticosteroids will lead to an increase in immunity, so it may be a countermeasure against the coronavirus that is currently prevalent all over the world and the influenza virus that must be taken care of in the future.

In fact, when I take a cold shower, I feel that it is difficult to catch a cold, probably because it is difficult to cool the water.

Please continue to take a cold shower after taking a bath and feel the change in your body.
