The feeling of cold limbs is mainly due to the drop of temperature, which leads to the contraction of capillaries and less blood flow than limbs, which makes the body surface and limbs cool.

When it rains and gets cold, everyone will feel cold. It's no big deal. If you are weak and sick at ordinary times, you need to exercise more and supplement it appropriately.

You can soak your feet with mugwort leaves, or you can buy special foot-soaking tablets. Soaking feet can promote blood circulation, and it will be very comfortable after soaking. Hot water itself can also be heated, making you feel very warm.

In addition, you can jump rope, which is a very good exercise. Like swimming, it can stimulate the whole body movement, exercise the heart and lungs and promote blood circulation.
