For people with diabetes or circulatory problems, wearing tight socks can restrict blood flow and increase the risk of foot ulcers, a serious complication. Overheated feet can also disrupt the body's natural cooling system during sleep, impairing REM sleep and causing fatigue the next day.
Tip: When possible (and even when it isn't),
do this: wear loose, breathable cotton or bamboo socks.
Avoid: tight-fitting socks, nylon socks, or thick wool socks, especially if you have diabetes, neuropathy, or sweaty feet.
Tip: If your feet get hot at night, take off your socks; it's your body's signal that it's time to cool down.
In short? Sleeping in socks can be beneficial for some... and detrimental to others. Listen to your body, choose the right material, and you'll wake up refreshed and ready to go without regretting that extra layer.
