How to keep warm when sleeping in winter
1, exercise before going to bed
Before going to bed, you can go out for a walk, mainly for fifteen to twenty minutes, until you feel hot.
Because a large part of the reason for cold feet in winter is poor blood circulation, the heat generated by organs can't be transferred to the feet well through blood, which leads to cold feet, so exercise can not only keep your body warm, but also speed up blood circulation. It should be noted that it is advisable to exercise for half an hour before going to bed, otherwise it may affect sleep.
Step 2 soak your feet with hot water before going to bed
Soaking feet is the most effective way to warm feet before going to bed. Most people soak their feet before going to bed. It is a well-recognized saying in the field of Chinese medicine that when your feet are warm, your body will be warm. However, if your feet get cold before going to bed, your body can't sleep any more. Pay attention to the water level and water temperature when soaking feet. The water level should be two or three inches higher than the ankle, and the water temperature should be in the range of 4 1 to 45 degrees. You should feel a little hot when your feet are just soaked in water.
3. Cover a warm quilt
In fact, the most important thing to keep warm when sleeping is to keep the quilt warm enough. The main quilt is not needed to keep warm and other things. Duvets and silk quilts on the market have a good warm-keeping effect, but their prices are more expensive than others.
