Go to bed early and get up late in winter, and it is best to get up after the sun comes out. Because going to bed early can maintain human yang and keep the body warm, while getting up late can nourish human yin. Do it at sunrise, get up and stop the cold, and ask for its warmth. Don't sleep with your head covered when it is warm. If the air in the bed is not circulating, there will be less and less oxygen. Over time, the air will become turbid. When people sleep in such an environment, they will feel chest tightness, nausea, or wake up from sleep with a cold sweat and feel tired the next day.

Dong San Bao nuan

1, warm head: When the head is cold, the blood vessels will contract and the muscles of the head will be tense, which may easily cause headaches, colds and even gastrointestinal discomfort.

2, warm back: cold stimulation can affect local muscles or introduce internal organs through back acupuncture points, which is harmful to health. Cold in the back not only causes backache, but also affects the muscles, joints and internal organs of the upper and lower limbs through the cervical vertebrae and lumbar vertebrae, causing various discomforts.

3. Keep your feet warm: once your feet catch cold, reflexivity will cause capillary contraction of upper respiratory mucosa, cilia swing will slow down, and your resistance will decrease. The consequence is that viruses and bacteria take advantage of it and multiply in large numbers, which makes people catch a cold.

Three methods of nutrition in winter

1, hot water soaking feet: soaking feet with hot water at 55-70 degrees Celsius before going to bed can not only relieve fatigue, but also help sleep. There are many acupoints on people's feet, which can relax tendons and activate collaterals, accelerate blood circulation, and play a role in preventing and treating diseases, especially for patients with chilblain and varicose veins of feet.

2. Wash your face with cold water: In winter, due to the stimulation of low temperature, the facial skin shrinks. Wash your face with hot water, then you will feel warm. Once the heat is lost, the capillaries will return to their original state, which is easy to wrinkle the facial skin. When I washed my face with cold water in the morning, I suddenly felt my eyes clear. The stimulation of cold water can not only improve facial blood circulation, but also enhance skin elasticity.
