1, cold prevention tips in late spring
1, respiratory medicine: cold and asthma in spring.
Zhu Xiaoli, Chief Physician of Respiratory Medicine: Respiratory diseases are high in spring. If you don't add clothes in time, people with low immunity, such as the elderly and children, will easily catch a cold. After cold air stimulation, it will lead to decreased airway immunity and impaired function, and then increase airway responsiveness, causing cough, chest tightness and even asthma and dyspnea. Therefore, when the temperature drops suddenly, patients with asthma and chronic bronchitis are prone to relapse or aggravation. Everyone reacts differently to these stimuli, and people with family history and sensitive constitution will be more serious.
Experts suggest that people with weak constitution had better go out less in cold weather. When going out, you can wear a mask, add clothes, and keep your head, chest, back and feet warm to avoid catching a cold.
2, gastroenterology: cold in spring, old stomach trouble is easy to attack.
Lu, Chief Physician of Gastroenterology: Low temperature is the high incidence period of gastrointestinal diseases, because low temperature stimulation will cause capillary contraction, affect gastric acid secretion and blood circulation in the stomach, thus leading to acute stomach spasm, gastric ulcer and gastroenteritis.
Experts suggest that many patients who have been admitted recently have "old stomach problems" after catching cold, so people with stomach problems should pay special attention to keep warm this season and increase or decrease clothes in time according to climate change to prevent their abdomen from catching cold. Pay attention to keep warm and nourish the stomach, drink more hot water, eat less cold food and eat on time. Exercise moderately, and don't sweat excessively. Regular daily life, remember not to stay up late and don't think too much.
3. Cardiology: Sudden drop in temperature and heart injury.
Chief Physician of Cardiovascular Department of Tang Dynasty: Due to the large temperature difference between morning and evening, the number of patients with coronary heart disease and myocardial infarction increased significantly. Most patients with coronary heart disease are highly sensitive to weather changes, especially cold weather. Sudden cold stimulation can cause coronary artery spasm, acute myocardial ischemia, angina pectoris and even myocardial infarction. When the weather is cold, outdoor activities should be reduced, and the increase of blood viscosity is easy to form thrombus and induce myocardial infarction. The sudden drop of temperature, vasoconstriction and high blood pressure are easy to cause myocardial ischemia. In addition, respiratory tract infection is easy to induce pneumonia, which will also cause heart overload and become an important cause of myocardial infarction.
Expert advice: the elderly should pay attention to keep warm and use drugs rationally to control blood pressure. If you have chest tightness, dull pain or palpitation, you should pay special attention even if the attack time is very short.
4. Neurology: The cerebral infarction in early spring is terrible.
Guo Yijing, Deputy Chief Physician, Department of Neurology: Spring is the season of high incidence of cerebral infarction, especially many elderly people go to the toilet at night or get up in the morning to have a stroke together. This time is also the coldest time of the day. The sudden drop of temperature, large temperature difference between day and night, low air pressure and high humidity are all easy to stimulate the nerves that control blood vessel activities in the body, leading to continuous spasm of arterioles, which suddenly increases blood pressure and leads to stroke accidents. When sleeping at night, people are at rest and their blood viscosity increases, which is also an important reason for the high incidence of stroke at this time.
Expert advice: once you find symptoms such as numbness or weakness in one limb, numbness or skew in one face, unclear speech, dizziness with vomiting, you must be highly vigilant and go to the hospital for examination and treatment immediately. Every second counts for three early strokes: early identification, early rescue and early thrombolysis.
2, cold spring health coup
1, keep the soles warm and enhance the resistance during physiological period.
Do you want to wear beautiful shoes as soon as spring arrives, even in the physiological period when you are most afraid of cold? However, Chinese medicine believes that people can't catch cold on the soles of their feet, because there is less fat on the soles of their feet, and many acupoints correspond to human internal organs. Cold feet can cause a lot of visceral discomfort. When it is cold in spring, remember not to wear sandals at home or after taking a shower. Especially during the physiological period, we should pay attention to keep warm, try to wear single shoes in late spring, and pay attention to sole exercise at ordinary times.
2. Foot exercise methods
Two hours before going to bed, at home or outdoors, stand up straight, stand on tiptoe, touch the ground with your feet and toes, and walk with your arms swinging at a faster speed and with greater strides for more than 20 minutes every day. Pay attention to step by step, and don't take too long at first. Wash your feet with hot water before going to bed, dry them, rub, pat and beat the soles of your feet with your hands. The effect will be better.
3. Do some slow-paced exercise
Spring has come, everything has revived, and I can finally go out! However, it should be noted that you can't do strenuous exercise, otherwise the organs that have become fragile after the bad weather in winter are more vulnerable to damage, sweat too much, open pores, get cold easily, and induce colds. You should choose gentle and gentle sports, such as brisk walking, jogging, jogging and flying kites. Be sure to do warm-up activities before exercise; Wear clothes moderately when exercising, and shoes should be light and soft; Wipe your sweat and change clothes in time after exercise to avoid injury or cold.
4. Open the window for ventilation three times a day.
Although the weather is getting warmer, the cold in late spring will still make many people close their doors and windows to keep warm and pay no attention to ventilation, which is particularly easy to breed bacteria and germs. Open the window frequently during the day to keep the air fresh and sunny.
Reminder: keep the window opening time at about 30 minutes, 3~4 times a day; We should not blindly rely on incense and ozone air filters to maintain indoor air quality; It is not advisable to open more windows on cloudy days and before 10 every day, because there are many floating dust in the air and the air quality is not good.
5. Go to bed late and get up early. The flu keeps me away.
Late spring cold, a weather change in which cold and warm air exchange with each other, causes the temperature to drop and rise many times, which is beneficial to the reproduction of various bacteria and germs. Moreover, the wind is mostly windy in spring, and the chances of human inhaling bacteria and germs have also increased. Therefore, we should keep enough rest and sleep in spring, because people's rest and sleep will directly affect the level of resistance. But the more sleep, the better. Usually 7.5? 8.5 hours is good. And spring advocates going to bed late and getting up early, and keeping in good health should be natural. In spring, the days get longer and the nights get shorter, so people's sleep time should be changed accordingly to nourish the yang. Note that "late" here means going to bed around 10: 30 at night, and "early" means getting up around 6: 00 in the morning.
Reminder: When sleeping in late spring, you should choose a suitable quilt, and it is best to use a winter duvet to keep warm, light, breathable and sweat-wicking.
6. Don't exercise until the sun comes out.
Spring exercises should be held after sunrise. It is best not to exercise when it is dark, especially not where there are green plants! Because it is foggy in spring morning, the temperature will be very low in late spring when it is cold. Bacteria are very active in spring, the air is filled before the sun comes out, and air pollution such as dust is not suitable for exercise. Also, plants can't carry out photosynthesis at night and will emit more carbon dioxide. Exercise beside plants before dawn will consume a lot of carbon dioxide, which is not good for your health. After the sun comes out, it can kill bacteria, promote plant photosynthesis and release more oxygen, which is very helpful for cardiopulmonary regulation.
7, cold and warm, "spring cover" can not be too much!
Chinese medicine advocates "covering spring and freezing autumn", and don't take off your winter clothes immediately because the weather gets warmer. Because people are used to wearing more clothes in winter, the regulation function of body heat generation and radiation is in a relatively balanced state with the environmental temperature in winter, and casually reducing clothes will destroy this balance. Once the temperature drops, the human body's resistance drops, which will lead to various diseases.
Take off your clothes in spring and follow the principle of decreasing. If you take off your clothes in a hurry when it is hot, your body can't fully adapt to the temperature in the morning and evening, and it is easy to get sick. You can choose to reduce clothes after bathing, because the hot air generated by bathing can make the human body quickly adapt to the external temperature and play a transitional role; "Spring Cover" can't be worn blindly. "Cover transition" will make hot air accumulate in the body and cannot be dispersed, hurting internal organs and covering up the illness; Chunwu also advocates "the upper part is thin and the lower part is thick", because the blood circulation in the lower part of the human body is worse than that in the upper part, and it is easier to catch cold.
8, yoga stretching, let the pressure disappear.
Yoga stretching can stretch shoulders, neck, back and limbs, effectively eliminate fatigue and depression, promote blood circulation and enhance body resistance. Keep practicing, and you won't be knocked down by the cold of late spring in this spring with great temperature difference!
9. Stretch your arms
Sit cross-legged on the ground, put the instep of your left foot on your right knee, cross your fingers, raise your arms straight above your head, palms up, and open your shoulders and chest.
