Are cold showers good for scalp health?
When you say to rinse your head, it is natural to use hot water, but by combining it with cold water, you can lead to a healthy scalp environment. In this article, we will introduce why cold water showers lead to a healthy scalp environment and effective methods.
Why cold water showers are good for the health of the scalp environment
This is because blood vessels expand and contract repeatedly, improving metabolism and activating the scalp, which improves blood flow.
Rinsing is usually done with hot water, but you can get such an effect by combining cold water at that time. The human body cools down when it warms up and tries to warm up when it cools down, so this is a method that utilizes this.
If you apply hot water to your scalp for a while, your blood vessels will expand and you will feel warm. This is enough to improve blood flow, but by switching to cold water and applying it to the scalp, the blood vessels will constrict.
Then, the blood flow worsens (at the same time, it tries to warm up and dilate the blood vessels), but here we switch to hot water again and apply it to the scalp to dilate the blood vessels again and improve the blood flow. By repeating this several times, the blood vessels are stimulated and the blood flow is greatly improved.
Improving the blood flow in the scalp makes it easier for the scalp to become softer, making it easier for nutrients to reach the hair. It also helps lift up your face.
Cold water shower method and precautions
I will show you how to take a cold shower.
- First, rinse thoroughly with warm water and shampoo.
The warm water dilates the blood vessels, and the stimulation of the shampoo further improves blood flow. - Massage after shampooing.
By softening the scalp, the blood flow will improve further. - Rinse thoroughly with hot water.
Rinse the bubbles thoroughly to dilate the blood vessels and prepare to apply cold water. - Switch to cold water and rinse.
Apply it to the entire scalp through your fingers to constrict the blood vessels. - Switch to hot water and rinse.
Apply it to the entire scalp through your fingers to expand the blood vessels. Repeat 4-5 for 2 sets. Repeated expansion and contraction of blood vessels promotes metabolism. - Finally, rinse with cold water to finish.
The aim is to make the blood flow better by trying to expand it by lightly contracting it at the end. It will get warmer and warmer later.
The point to note is the time to apply cold water. Excessive cold water constricts blood vessels and conversely reduces blood flow. This is done only to improve blood flow, so the main thing is to warm it with hot water to expand the blood vessels, and then add cold water to the extent that it contracts quickly. It is NG to cool down.
Also, suddenly pouring cold water on you can catch a cold, or your heart will be shocked. Use lukewarm water for a while, and then use cold water when you get used to it.
*Please do not practice this exercise as it is not recommended for those with a weak heart or the elderly.
By combining hot water and cold water shower, you can easily get a beauty effect on your scalp. Practicing this will lead to a healthy scalp environment and create a foundation for enjoying more fashion, so I hope you will incorporate it into your bath time.
