3. Tips on how to keep warm in daily life

Care plan for cold hands and feet

Soak your feet every day

Soaking your feet is the most effective method. Add hot water of about 40 degrees into a deep basin and let the water cover your ankles. After soaking for about 20 minutes, you will feel your whole body heating up, which means that your body starts to heat up after the blood circulation is smooth. If you rub your feet while soaking them, the effect will be better.

Aerobic exercise

Jogging, brisk walking, rope skipping, disco dancing, Tai Chi, etc. will make all parts of the body move and promote blood circulation, but do not exercise excessively. High-intensity exercise and heavy sweating will "vent the yang energy" and have the opposite effect.

Wear cotton socks

Pure cotton socks are not only soft and comfortable, but also absorb foot sweat, keeping your feet dry and comfortable all day long.

Eat calorie-supplementing foods

The weather is cold. In order to increase calories and improve cold hands and feet, you should deliberately take supplements. In the cold winter in the north, you can supplement with warm and hot foods, such as beef, mutton or dog meat; while in the south, the climate is milder, so sweet and warm foods, such as chicken, duck and fish, are more suitable; and you should try to eat as little cold fruits as possible Such as pears, water chestnuts, etc.

Ensure adequate sleep

Ensure at least 6 hours of sleep every day. Adequate sleep is conducive to the storage of yang energy and the accumulation of blood.

*** The soles of hands and feet

When you have time, you can rub the soles of your hands and feet frequently to improve the microcirculation of the terminal blood vessels and have the effect of warming your hands and feet.

Wish you good health!

4. Does anyone know some common sense about preventing cold hands and feet?

Eat more foods that promote blood circulation, such as sesame seeds, spinach, peanuts, tofu, fresh fish, garlic, green onions, Chili, curry.

The protein, fat, vitamins B1, B2, amino acids, and iron in beef and mutton can also improve cold hands and feet.

The main reason for cold hands and feet is that the function of the autonomic nervous system is not regulated smoothly and the blood vessels become thin.

In addition, toes, knees, shoulders, fingers, etc. are all joints that move more. They have less fat, so heat is easily lost, and there are fewer blood vessels, making it easier to feel cold. Due to physical weakness, it is more likely to cause cold hands and feet.

You need to exercise more to strengthen your physique! Do more aerobic exercise such as jogging, brisk walking, mountain climbing, rope skipping, disco dancing, Tai Chi, etc., which will make all parts of the body move and promote blood circulation! Be sure to keep warm in a scientific and reasonable way. Drink some red wine before going to bed to soften blood vessels and promote metabolism! Often lie under the quilt, go to hot springs, saunas, and hot baths to promote blood circulation. This is mainly because the temperature in nature decreases and Yang Qi is insufficient. The human body's own Yang Qi will also be insufficient, and the body will show symptoms of Yang deficiency.

In addition, because of the cold weather, the human body's blood vessel contraction and blood return capacity will be weakened, resulting in poor blood circulation in the hands and feet, especially the fingertips, which is often referred to as "poor nerve ending circulation." As a result, my hands and feet always feel cold. This situation generally occurs in women, especially in middle-aged and older women. Mental workers are more likely to have cold hands and feet than manual workers, but it rarely occurs in healthy young men.

Improvement methods: 1. Eat American ginseng. This is a good medicine for replenishing qi. It is gentle in nature, tonifying but not drying.

Can be soaked in water alone for drinking. 2. Eat sesame seeds and peanuts.

Rich in vitamin E and various nutrients, it can help the absorption of vitamin B and strengthen the nerve's ability to resist cold. Vitamin E also has the effect of dilating blood vessels and can enhance blood circulation in the peripheral limbs.

3. Eat onions, peppers and other foods that can help the body generate heat and promote blood circulation. Other measures: Usually use hot water to soak your feet, which can not only warm the body, but also relieve fatigued nerves.
