1 How to keep warm in winter
1. The heating temperature should not be too high. John Skoll, an expert in vascular surgery at the Affiliated Hospital of University College London, said that the temperature of air conditioning and heating is too high, and the temperature difference between indoor and outdoor is too large. When going out, small blood vessels often contract suddenly, making people feel colder. Therefore, the indoor temperature should be 18℃~20℃.
2. Eat less caffeine. Eddie Charona, an expert in vascular surgery at the General Hospital of Liuyishem, UK, said that caffeine has the function of dilating blood vessels, which makes them not easy to contract naturally under cold conditions, leading to the loss of body heat and making people feel colder. Hot drinks without caffeine, such as ginger tea, have better warmth retention effect and are more suitable for drinking in winter.
Don't put your hands in your pockets. Tim Hatchev, an expert of the British Chiropractic Association, said that when walking in winter, don't put your hands in your pockets, but put on gloves and shake your arms, which can move your arm muscles, improve the blood flow of your arms and hands, and keep your body warm.

Dr Sarah Sink, a nutritionist at the British Dietetic Association, said that intake of protein can significantly increase body temperature compared with intake of carbohydrates or fats. It is recommended to drink a cup of soybean milk for breakfast, and at the same time, you can eat some nuts and yogurt properly.
5. Cover your ears with a hat. Dr Andrew Camille, an otolaryngologist at the University Hospital of South Manchester, said that head heat dissipation accounts for 30% of body heat dissipation. It is best to choose a hat that can cover your ears, because although your ears are thin, they have a large surface area and are easier to dissipate heat.
6. Move your toes before getting up. Sammy Margo, a British physiotherapist, suggested that before getting up, you should move your toes up and down 20 times, then move your ankles in circles with your feet, 65,438+00 times in both directions, and then tighten and relax your thighs 65,438+00 times.
