It's getting cold. Starting from today, I began to take cold and hot baths again.
Hot and cold water baths are especially beneficial to your health. Hot water can dilate skin blood vessels, while cold water can contract blood vessels. Alternating hot and cold water is like letting blood vessels do gymnastics. If we can persist for a long time, the human body can better adapt to the cold and hot changes of the external temperature. It can not only prevent allergic rhinitis, but also prevent colds and chilblains, improve breathing and increase vital capacity. Cold water has an exciting effect on the brain and nerves, which makes the mind clear, while hot water can relieve fatigue. After a hot and cold bath, I feel very relaxed all over.
The specific method is: firstly, flush the whole body with hot water, then put out the fire of the water heater and let the faucet naturally flow out cold water. When the washing is almost finished, turn on the hot water, rinse the soap bubbles and dirt thoroughly, then rinse with cold water, and finally warm up with hot water. This hot-cold-hot-cold-hot, three hot and two cold, the effect is very good. Especially in winter, hot water suddenly turns into biting ice water, and you can't help shouting, which is very cool.
This method can be implemented from the cool autumn, because Guangdong is hot in summer and hot water can't stand it. "Spring should be covered and autumn should be frozen." I'm in favor of starting in autumn. At this time, using cold and hot water can exercise the body's adaptability to external temperature changes and improve its cold tolerance. The body is in a very healthy state, and the whole winter has passed unconsciously.
For alternating hot and cold bathing, we should pay attention to the following issues:
1, from autumn to spring, persevere. The duration of bathing should be determined according to personal health, and it is advisable to feel good and comfortable after bathing.
2, suffering from severe hypertension, coronary heart disease, rheumatism, cavitary tuberculosis, sciatica, menstrual women, pregnant women and patients with high fever should not take a bath alternately.
3. This method is only applicable to people aged 16 ~ 50, not to the elderly and infirm.
About cleaning the nose
In addition, when taking a bath every night or washing your face in the morning, it is best to wash your nose with cold water and clean it thoroughly. This can not only remove dust, clean nasal secretions and keep the nose clean, but also stimulate the nose and maintain its stress function, thus avoiding colds and rhinitis. If you get over your cold, use it. Many colds will get over soon.
Guangdong is one of the regions with the highest incidence of nasopharyngeal carcinoma in the world. Apart from genetic reasons, special virus, hot and humid climate in Guangdong, Guangdong people's eating habits and industrial pollution are definitely one of the biggest reasons. Polluted dust in the air enters the nasal cavity, which stimulates and pollutes the nose, causing nasal inflammation, and long-term stimulation leads to nasopharyngeal carcinoma.
As the saying goes, "illness comes from the mouth." Don't forget that there is also a "disease from the nose". Moreover, most diseases such as colds (upper respiratory tract infections) and pneumonia are inhaled through the nose.
Cleaning the nose can clean the dust and bacteria outside, keep the nose clean and stimulate the epidemic prevention function of the nose. It can be said that if the nose is cleaned up, the cold can be reduced by at least half, and the incidence of rhinitis and nasopharyngeal carcinoma can be reduced by two-thirds or more. I clean my nose when I wash my face and take a shower every day. Sometimes I go out of the office to go to the bathroom. Besides washing my face, I will clean my nose if it is convenient, and then look in the mirror to make sure there is no dirt and keep the necessary gfd.
