1, the misunderstanding of health preservation in winter
Myth 1: It's easy to catch a cold when it's cold.
The single factor of low temperature will not cause people to get the flu. On the contrary, in cold weather, the number of antiviral cells in the body actually increases, which is a way for the human body to resist cold temperature and pressure. According to the National Institute of Allergy and Infectious Diseases, influenza virus grows most easily at 32.8 degrees Celsius.
Myth 2: Outdoor sports are unnecessary.
Even if it is cold, you should do outdoor sports. A study published in the Journal of Sports Medicine and Science shows that in cold weather, doing more exercise can increase the secretion level of endorphins in the body and resist the depression in winter.
Myth 3: There are fewer allergic attacks in winter.
Allergies will be more obvious in winter, leading to discomfort such as stuffy nose and itchy throat. According to the American Asthma and Allergy Foundation, 1/5 people will suffer from allergies, and indoor allergies will be more serious in winter. Frequently closing windows will lead to poor indoor air quality, easy to breed mold, and lead to frequent episodes of allergies in winter. If your symptoms persist for more than 10 days, or if you still do not relieve after taking antihistamines, you should go to the Allergy Department in time.
Myth 4: Sunscreen is unnecessary.
Professor Robert Jeddah, an expert in plastic surgery in new york, said: "In the winter months, the surface of the earth is closer to the sun, and people are often exposed to more harmful rays without realizing it." More importantly, snow and ice can reflect up to 80% of harmful ultraviolet rays, which is equivalent to a double blow to the skin.
Myth 5: Less sun exposure can lead to depression.
Although dim light is certainly not helpful for depression, there are many other factors besides seasonal affective disorder that lead to winter depression, especially during holidays. Busy schedules, family pressures and worries about holiday spending are more likely to lead to depression than seasonal affective disorder. If you feel depressed and backward for a period of time, seek help from your family and doctors in time.
Myth 6: Women will gain weight by about 10 kg.
Eating a lot of pleasant but not necessarily healthy junk food, dull weather and comfortable blankets hinder outdoor sports, which will all lead women to gain weight in winter. But it turns out that the average woman gained 0.5 kg ~ 1 kg in one winter. A study published in the New England Journal of Medicine shows that after the arrival of spring, most women have not lost the extra weight gained in winter, so that these weights will accumulate. Therefore, proper exercise in winter and active exercise after spring can keep the body from getting too fat.
Myth 7: Cold climate is easy to lose hair.
Cold weather actually helps to keep hair. Researchers from the Affiliated Hospital of Zurich University in Switzerland followed up 823 women for 6 years and found that their hair loss was the most in summer, but the least in winter. However, dry scalp will lead to unhealthy hair growth, which is fragile and easy to break, so it is necessary to reduce the number of shampoos and keep the hair moist; Choose a shampoo with neutral PH value; Don't dry your hair hard after washing, but wrap it in a dry towel and gently press it to let the water absorb.
Myth 8: Drink some wine, and your body will be warmer.
After drinking, the blood vessels in the skin will expand, and the blood will flow to the peripheral blood vessels, but it will stay away from the internal organs. With the acceleration of blood circulation, a lot of heat in the human body is lost through the skin, but the body temperature will drop rapidly. Not only can it not keep out the cold, but it is also easy to cause symptoms such as colds and frostbite.
Summary: How many misunderstandings did you mention in the article? For the sake of health, please correct it in time, correctly understand the knowledge of winter health preservation and live a healthy winter.
2. Precautions for winter lunch break
1, cold current invasion
Taking a nap in the office in winter is easy to catch a cold. After the human body goes to sleep, its body temperature drops and its resistance becomes weak. When it falls asleep on the table, the cold invades from the back and feet, which will cause diseases such as colds.
