Which part of the body is most afraid of cold?

　　As the temperature drops in autumn and winter, many people will feel particularly chilly in some parts of their bodies. Even if they are dressed thickly, there is still a chill. Which part of the body is most afraid of cold? Why are these parts susceptible to cold?

These parts of the body are most sensitive to cold

　　1. Head

　　The skin on the head is thin, the blood vessels are dense, and the heat is lost quickly, accounting for about 30% of the body's heat dissipation. When the head is exposed, cold air directly stimulates the scalp and blood vessels, easily causing headaches and dizziness, and may also affect blood circulation throughout the body.

　　2. Feet

　　The feet are located at the end of the limbs, far from the heart, have a weak blood supply, less subcutaneous fat, and poor heat preservation capabilities. After the feet catch cold, the blood vessels will constrict, which will affect the blood return throughout the body, and may also lead to colds, diarrhea and other conditions.

　　3. Neck

　　The neck is rich in blood vessels and nerves, and the fat layer under the skin is thin. It is a key part connecting the head and trunk. Cold exposure to the neck will stimulate vasoconstriction, which may cause neck pain and affect the blood supply to the brain.

　　4. Abdomen

　　There are many internal organs gathered in the abdomen, the skin of the abdomen is highly sensitive, and the fat is unevenly distributed. Cold in the abdomen can easily cause vasoconstriction in the gastrointestinal tract, affecting digestive function, causing abdominal pain and diarrhea, and women may also feel abdominal discomfort.

　　5. Knee joint

　　The knee joint is composed of bones, ligaments and joint capsules. The surrounding muscles and fat are less protected and have insufficient heat reserves. Cold air stimulation will constrict the blood vessels around the knee joint, worsen blood circulation, and cause joint stiffness and pain.

How to keep warm parts sensitive to cold in autumn and winter

　　1. Keep your head warm and wear a hat

　　Choose a breathable and warm hat, mainly made of wool or knitted fabric, and wear it promptly when going out to avoid direct exposure of the head to cold wind and reduce heat loss.

　　2. Keep your feet warm and soak your feet frequently

　　Soak your feet in warm water around 40℃ for 15 minutes every day to promote blood circulation in your feet.； Wear thick socks and non-slip, warm shoes, and avoid walking barefoot or wearing single shoes.

　　3. Neck warm scarf

　　Choose a soft and warm scarf to wrap around your neck when going out to prevent cold wind from flowing in due to a loose collar. You can also wear high-collar clothing to protect your neck when working.

　　4. Abdominal warmth and protective gear

　　Wear clothes with a waistband or a cotton waistband to avoid wearing midriff-baring clothes； Cover yourself with a quilt when sleeping at night to prevent your abdomen from getting cold.

　　5. Keep your knees warm and wear knee pads

　　Wear fleece knee pads when going out to reduce cold air irritation； Avoid standing in a cold environment for a long time, wipe off sweat promptly after exercise, and keep warm.
