Normal or not, wearing socks may be smart if you’re having trouble falling asleep. There may be something to the old advice that warming your feet can speed up your trip to dreamland. Heating cold feet causes vasodilation which may tell the brain that it is bedtime. After the blood vessels open in the hands and feet, heat is redistributed throughout the body to prepare for sleep. In fact, some research has shown that the more vasodilation in the hands and feet, the less time it takes to fall asleep. The relationship between warm hands and feet and falling asleep may be what’s behind the age-old belief that placing a hot water bottle at the foot of the bed is good for sleep. Socks in bed may not be sexy, but then again, neither are cold feet! You may wonder what socks you should wear to keep your feet warm in bed. Socks made of natural soft fibers such as merino wool or cashmere are best. They usually cost more than cotton or artificial fiber socks, but they are well worth the extra money. Make sure the socks you choose are not tight-fitting, which might constrict circulation and hinder proper warming of your feet. To enhance circulation, you can put some massage oil or favorite moisturizer on your feet before going to bed. Warm your socks by sitting on them or using a hair dryer before putting them on. If you are afraid it would be overheat or your feel may get too hot, leave your feet outside your blanket. A pair of breathable socks might be even helpful for people with insomnia. Many socks factory and socks distributors can even customize socks according to your requirements. Maybe you don’t like to wear socks all day long, however, a pair of breathable socks will probably give you a good night's sleep!
