1, increase calorie intake. In cold weather, the human body consumes more energy, so it is necessary to appropriately increase the intake of calories, such as protein, fat and carbohydrates. In order to avoid excessive fat intake, choose foods with low sugar, low fat and high calorie, such as fish, chicken and beans. The "three white soup" made of white radish, onion and garlic helps to improve the body's cold resistance.

2. Do some aerobic exercise. Many people start "cat winter" in winter, which will only make them more and more afraid of the cold. Do some aerobic exercise in moderation, such as walking and swimming. Before getting up, you can do simple stretching exercises under the covers, and then turn your ankles, which can promote blood circulation throughout the body.

3. Warm your feet. The foot is called the "second heart" of the human body, and the cold easily invades the body from the foot, affecting immunity. Choose warm and comfortable shoes, such as cotton shoes. Wear less leather shoes with fast heat dissipation and hard materials. Soaking your feet with hot water every night before going to bed can not only relax your whole body, but also feel the warm current spreading along your feet.

4. Control the temperature. In winter, people with large indoor and outdoor temperature difference, poor ventilation and poor body temperature regulation are prone to cause diseases. It is suggested that the indoor temperature should be controlled at 18℃~20℃, and the maximum temperature should not exceed 26℃.

Precautions for keeping warm:

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.

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.
