The benefits of taking a cold shower in summer

1. Rapidly cool down and relieve heat

In summer, taking a cold shower can effectively relieve the heat in your body and refresh you.

2. Skin care and beauty

Cold water baths can enhance the nutrient supply to the skin and subcutaneous tissue, increase sebum secretion, make the skin rosy, shiny and elastic, and less susceptible to skin diseases. Health Tip: Cold showers are not suitable for everyone. Cold water bath exercises should not be performed on an empty stomach, after a meal, or immediately after strenuous exercise. People with unhealed skin wounds, weak constitutions, or fever should not take cold water baths. In addition, people who are allergic to cold water, suffer from severe hypertension, coronary heart disease, rheumatism, tuberculosis, and sciatica should not take cold showers.

3. Prevent colds

When the human body is frequently stimulated by cold water, its muscles tense and contract, and it quickly responds to resistance, thereby enhancing the body's ability to adapt to temperature changes, strengthening the body's immune function, and preventing upper respiratory tract infections such as colds.

4. Promote blood circulation

Good blood circulation is critical to overall cardiovascular health. Having healthy blood circulation can help you recover quickly after strenuous exercise. Alternating hot and cold water in the shower is an easy way to improve blood circulation. In order to keep the organs warm, a large amount of blood will flow into the organs after taking a cold shower. Warm water has the opposite effect. Promotes blood flow to the surface of the skin. Compared with warm water baths, cold water baths can stimulate the circulatory system, making people healthier and looking younger.

What are the downsides of taking a cold shower?

The disadvantages of taking a cold shower for people with poor physical condition

People with poor physical constitution should not take cold showers. Otherwise, their poor resistance will be stimulated by the cold and may cause colds, fevers and other diseases. When you are sweating profusely and feeling extremely hot, and want to cool down as quickly as possible, it is unscientific to take a cold shower to relieve the pain of the heat. Because, due to the sudden stimulation of cold water, the skin blood vessels immediately contract, the blood circulation resistance increases, the heart and lung burden increases, and at the same time the body's resistance is reduced, potential bacteria and viruses in the human body will take advantage of the opportunity to enter, thus causing disease.

Disadvantages of taking a cold shower after exercise

Just for the sake of momentary pleasure, you may take a cold shower from head to toe after exercise. It may feel refreshing at the time, but afterwards you may feel weak all over, and some may even have a headache. This is because when the body sweats profusely, the capillaries are in an expanded state. If you take a cold shower, the blood vessels will contract sharply, and the heat in the body will be affected by external factors and cannot be dissipated for a while. In addition, the brain is rich in arteries and is very sensitive to external stimuli. In hot seasons, the head is particularly prone to sweating after exercise. At this time, if you rinse the head with cold water, it may cause abnormal function of the intracranial blood vessels, causing dizziness, headache, black spots in front of the eyes, and even vomiting. In severe cases, it may also cause intracranial hemorrhage.
