Drink hot drinks

A study published in the American Journal of Diseases pointed out that drinking hot drinks often can prevent colds and reduce the discomfort caused by colds. The reason is that Professor David Lacorre, director of the Department of General Medicine at the University of Wisconsin, pointed out that the odor and water vapor emitted by hot drinks can stimulate the production of saliva and other mucus, thus alleviating respiratory dryness and enhancing disease resistance. Green tea, black tea, lemonade, chicken soup, etc. Hot drinks are suitable for winter. When the hot drink is hot, stick your nose at a place about one punch away from the hot drink to keep breathing, and then drink it when it is not hot. This can strengthen the efficacy of antivirus and bacteria.

Drink green tea

German research shows that tea polyphenols contained in green tea can destroy and inhibit influenza virus and prevent human infection. American research also found that after taking the ingredients extracted from green tea, the chances of participants suffering from influenza decreased by 23%, and even if they were infected, the course of disease would be shortened by 36%. Green tea is slightly cold and should not be too strong in winter. It is suitable for people with hot and dry constitution who are easy to get angry, strong in sex and hot, which is helpful to reduce fire, but it is best to drink less for those with cold stomach.

Eat fermented food

Italian research found that fermented food contains probiotics, which can inhibit inflammation and control bacterial reproduction. A study published in the American Journal of Clinical Nutrition also pointed out that taking a certain amount of probiotics every day can reduce the risk of illness by 27%. "Eating fermented food often in winter can enhance immunity and prevent colds." Professor Shen, an expert from China Health Education Center, told reporters that yogurt is the most effective way to prevent diseases in fermented food. Yogurt can not only enhance immunity and produce antibiotics, but also regulate intestinal flora and prevent constipation and diarrhea. It's best to buy plain yogurt. Fruit yogurt often contains too much sugar.

Chewing gum

Chewing gum can not only bring fresh breath, but also prevent diseases. The latest research in Turkey found that chewing gum containing xylitol can prevent Streptococcus pneumoniae from establishing a base in the human body and reduce the risk of sinus and ear infections. Shen reminded that too much xylitol intake may cause diarrhea, so don't eat too much every day; Xylitol can also raise blood sugar, so diabetics should be careful to eat it.

Eat more ginger.

Studies in Taiwan Province have found that ingredients contained in fresh ginger can inhibit viruses attached to respiratory cells and reduce their replication ability, thus preventing respiratory diseases. Yang Li pointed out that winter colds are mostly wind-cold colds, and ginger is warm, which has the effect of relieving exterior and dispelling cold. You can drink ginger soup or stir fry. Need to be reminded that it is best to peel ginger soup, so that its pungent effect is better, and it is best not to peel ginger when cooking, which is conducive to maintaining the medicinal properties of ginger.

Eat deep-sea fish

Studies have shown that omega-3 fatty acids contained in fish can promote the formation of cells to fight infection and have certain preventive and therapeutic effects on respiratory tract infections. Shen said that deep-sea fish such as sardines, salmon and tuna contain more omega-3 fatty acids, so it is best to ensure that they are eaten twice a week. Walnuts and flaxseed are also rich in omega-3 fatty acids, so you can eat some properly.

Drink less

Many people think that drinking wine in winter makes them "warm" and don't like catching a cold. The latest research shows that heavy drinking may trigger a large number of cytokines, causing inflammation and fever. Shen said that after drinking, blood vessels in the skin will expand, blood circulation will accelerate, and a lot of heat in the body will be lost through the skin. Not only can't keep out the cold, but it is also easy to catch a cold. Therefore, it is better to drink less wine.

Methods to prevent colds in winter

Touch your nose and eyes less.

A study published in the Journal of Occupational Health 20 13 found that people who are used to picking their noses and touching their eyes in life have a higher risk of respiratory infection than those who are not used to it, because the virus will enter the human body through their noses and eyes. Experts remind that it is best to touch the five senses after washing your hands. There's really no way. It is suggested to use finger joints instead of fingertips. There are relatively few viruses and bacteria in finger joints.

Wash your hands frequently.

The US Centers for Disease Control and Prevention pointed out that frequent hand washing can effectively reduce bacteria on hands and prevent colds. Wash your hands carefully before and after meals, after going home from public places and after touching coins, nose, sputum and saliva. Wash your hands with soap or hand sanitizer and rinse with running water. There are many bacteria in your index finger, palm and forearm, so you should focus on cleaning them. It is best to wipe your hands with a paper towel after washing your hands. If you wipe with a towel, you should pay attention to regular cleaning and disinfection. Nails are hotbeds of bacteria. If you want to prevent colds, it is also important to cut your nails often.

Increase moisture

Dry weather in winter, coupled with the influence of heating or air conditioning, often leads to insufficient indoor humidity. American experts pointed out that when the indoor air humidity is lower than 40%, the respiratory tract is too dry and its antibacterial performance will be weakened. Once dust and bacteria attach to it, it is easy to induce respiratory diseases. Moreover, influenza virus likes dry environment, and it reproduces faster in dry environment. Therefore, it is best to prepare a hygrometer at home in winter. When the humidity is too low, turn on the humidifier or mop the floor with a wet mop to keep the indoor humidity at 40% ~ 60%.

warm oneself

Yale University School of Medicine found that regular sun exposure helps to prevent influenza and colds, because sun exposure helps to maintain a high level of vitamin D in the body and can reduce the risk of respiratory diseases by half. Shen suggested that adults should spend 30 minutes to 1 hour in the sun every day, and 10 is the best time to bask in the sun. Aquatic products, dairy products, eggs, mushrooms and other foods are rich in vitamin D, and you can also eat more appropriately.
