Khaberni - Recent scientific research has revealed that exposing a small part of the body to cold air, such as the feet, helps to accelerate the reaching of deep sleep stages needed by humans.
A study published in the American journal “Aviation, Space, and Environmental Medicine” found that cooling the feet is an effective way to reduce the overall body temperature, making it easier to feel comfortable, even when covered with a heavy blanket, according to the blisstulle website.
American psychology professor Natalie Dautovich stated on this matter: "Our feet are at the far ends of our body, and they have special connections called arteriovenous anastomoses that connect arteries and veins. When it is hot, these connections widen, allowing more blood to flow to the skin. This cools the body. Sleep and body temperature are closely linked. Just before sleep, the body temperature naturally drops. This cooling reaches its lowest levels during deep sleep."
For this reason, sleep experts advise taking a warm bath before bed. After coming out of the bath, the body temperature drops, mimicking the natural cooling that occurs before sleep, making one feel sleepy, according to the amerisleep website. For some, sticking one foot out of the blanket provides a calming sense of control over their sleeping environment.
Reducing Sweating
For individuals suffering from night sweats, leaving one foot uncovered can help prevent the body temperature from rising and the feeling of annoying humidity.
Since the feet contain many blood vessels close to the surface of the skin, they effectively help get rid of excess heat.
Some people suffer from an annoying problem called restless legs syndrome. It is a discomfort in the legs, especially at night. If you suffer from this syndrome, sticking one foot out may relieve your leg pain.
Some individuals have a high sensitivity to texture, weight, or temperature during sleep. Therefore, the sensation of air on their skin creates a comfortable sensory balance and provides the feeling of uncovering one foot with enough variety to relieve sensory overload and promote calm, according to the wicproject website.
Experts agree that maintaining relatively low temperatures helps the body achieve deeper sleep.
