The “cold winter†refers to the rapid rise in temperature in early spring (generally referred to as March) and the low temperature in the late spring (usually referred to as April or May) compared with normal years. Long-term rainy weather or frequent cold air intrusion, or strong radiation cooling under continuous cold and high-pressure control on a clear night can easily lead to cold spells. The weather in early spring is changeable. If the cold air is strong, the temperature may drop below 10°C, even in rain and snow. At this time is often sunny during the day, people have a kind of "heated wind smoked visitors drunk" feeling, sooner or later, but the cold attack, people feel that "the spring cold and steep." This kind of difficult-to-adapt "freakish" weather is often referred to as cold weather. The agricultural production and residents' lives are easily and adversely affected.
Harm to human health
The onset of cardiovascular and cerebrovascular diseases has a poor ability to increase the thermal balance of the elderly, and its circulatory system is easily stimulated by the cold. After the sympathetic nerve is stimulated by cold, the degree of excitement is increased, and the capillaries on the surface of the whole body are contracted, which increases the resistance of the blood flow and leads to an increase in blood pressure. In addition, sudden changes in the weather can cause changes in the Earth’s magnetic field and induce neurological disorders in the human body. Because elderly people and patients with cardiovascular and cerebrovascular diseases cannot adapt to this change, sudden increase in blood pressure, cerebral infarction, cerebral hemorrhage, or myocardial infarction may occur. A foreign experiment showed that a group of 63-70-year-olds sit and watch TV or read a book in an artificial climate room with a room temperature of 6°C. After two hours, the blood pressure of the elderly generally rises by about 25 mmHg. Under the same conditions, young people's blood pressure changes little. This shows that at low temperatures, it is easy for the elderly to contract their blood vessels.
In the early spring, some young, beauty-loving girls wore colorful skirts early on. However, female knee joints are more sensitive to cold air stimuli. After being attacked by cold air, the joints are prone to numbness and soreness. As time goes by, rheumatoid arthritis is prone to occur.
Easier to catch respiratory infectious diseases Because of the cold weather in early spring, the air is dry, and the defense function of the respiratory mucosa is directly affected. Bacteria, viruses, and other pathogenic microorganisms can take advantage of it, causing epidemics such as influenza and mumps. The data shows that the incidence of respiratory infectious diseases such as measles, diphtheria, whooping cough, scarlet fever, and tracheitis is much higher than in other seasons in the winter and spring alternate seasons.
Keep your feet warm and increase your resistance to physiology
Do you want to put on beautiful shoes early in the spring when you arrive, even in the coldest physiological period? However, Chinese medicine believes that people's soles cannot be cold, because the soles of the feet are less fat, and many of the acupuncture points correspond to the internal organs of humans. The coldness of the feet will cause many organs to become uncomfortable. When it's cold, remember not to wear cool sand when you are at home or after bathing. Especially during the physiology period, you should pay attention to keep warm. Try to change to a single shoe in late spring and pay attention to the soles of your feet.
Sole exercise
Two hours before going to bed, at home or outdoors, stand up straight, kick the heel, and place your feet and toes on the ground. Walk your arms faster and at a greater pace for more than 20 minutes a day. Pay attention to gradual and orderly progress. Don't start too long. Before going to bed, use hot water to wash your feet, dry them, and use your hands to knead, beat, and hit the soles of your feet. The effect will be better.
Slow-paced sports
Spring is coming, everything is recovering, it's hard to get outside! But be careful not to perform intense exercise. Otherwise, organs that become fragile after the severe winter weather will be more easily damaged, sweat too much, pores open, and they will be vulnerable to cold and cold. You should choose gentle and relaxing sports such as brisk walking, jogging, outing, kite-flying and so on. Before the sport must be prepared to exercise; sports should be moderate clothing, shoes should be light and soft; after the exercise to wipe sweat, change clothes, so that it will not be injured, catch cold.
Ventilation 3 times a day
Although the weather is getting warmer, the fact that many people will close the doors and windows tightly for warmth and don’t pay attention to ventilation will be particularly prone to breeding bacteria and germs. During the day, they should often open windows for ventilation and keep them fresh. Air and plenty of sunshine.
Reminder
Window opening time is maintained at 30 minutes or so, 3 or 4 times a day. You can't blindly rely on incense and ozone air filters to maintain indoor air quality. Cloudy and daily windows should not be opened before 10:00 in the morning. not good.
Get up late to sleep and get up early, the flu stays away from me
The cold and warm air exchanged between the cold and warm air changes the weather, causing the temperature to fall and recover several times, which is conducive to the reproduction of various bacteria and germs. Moreover, the spring wind is large and large, and the chance of inhaling bacteria and germs increases. Therefore, we must maintain adequate rest and sleep in the spring, because people's rest and sleep will directly affect the level of resistance. But not as much sleep as possible, generally 7.5? 8.5 hours is appropriate. In the spring, it is advocated that late-sleeping and early-to-early sleep should be carried out. Health should be smooth and natural. Spring should be lengthened during the day and nights should be shortened. People's sleep time must also be changed in order to maintain yang. Note that "night" here refers to falling asleep at around 10:30 in the evening, and "early" means getting up at around 6am in the morning.
Reminder
When you fall asleep during the cold period, you should choose the right quilt, it is best to still use the winter duvet, not only warm, thin, breathable, perspiration.
The sun did not come out, do not exercise
Spring exercises are performed after sunrise. It's best not to exercise when the sky is not bright, especially if you don't go to a place with green plants! Because the mist is heavy in spring and it runs out of cold, the temperature will be very low, and the spring bacteria will be very active. Before the sun comes out, it will be filled with air. With dust and other air pollution, it is not suitable for exercise. In addition, the nighttime plants are unable to carry out photosynthesis, and emit more carbon dioxide. When the sky is not bright, the body will take in a large amount of carbon dioxide when exercising next to the plants, which is not good for the body. After the sun comes out, sunlight has a bactericidal function, but it also promotes the photosynthesis of plants and releases more oxygen, which is very helpful for the regulation of heart and lungs.
Warm and cold, "Chun Chun" can not be too much!
Chinese medicine advocates "Spring and Autumn and Autumn and Frozen," and do not take off winter clothes as the weather turns warm. Because people in winter have become accustomed to wearing more clothes, the regulation of body heat production and heat dissipation is relatively balanced with the winter ambient temperature, and casually reducing clothes will undermine this balance. Once the temperature drops, the body's resistance drops, causing various diseases.
Spring undressing should follow the decreasing principle. If Tianyi fever rushes to undress, the body can not fully adapt to the morning and evening and the body temperature, it is easy to get sick; you can choose to bathe and reduce clothes, because the heat generated by the bath can make people adapt faster to the outside world The temperature plays a transitional role; the “Spring Breeze†can't be worn more and more, and the “Transition†will accumulate hot air in the body and it will not come out, hurt the internal organs, and cause illness; Chun Ye also advocates “under the thin "Thick" because the blood circulation of the lower part of the human body is worse than the upper part and is more vulnerable to cold attacks.
Yoga stretch, let the pressure without a shadow
Yoga stretch can stretch the shoulders, neck, back, and limbs, which can effectively eliminate fatigue and depression, promote blood circulation, and enhance body resistance. If you insist on practicing, you will not be overwhelmed with cold in the spring when the temperature difference is very big!
Arm extension
Sitting cross-legged on the ground, placing the left foot instep above the right knee, cross your fingers, straighten your arms over your head, and palm up, open your shoulders and chest.
