How to fall asleep faster is being discussed on TikTok – the app is buzzing
Fans of TikTok are discussing how to fall asleep faster. Some users write that wearing socks keeps the toes warm, creating a sense of comfort and coziness. At the same time, the temperature of other parts of the body decreases. Although there is a lack of quality research on how wearing socks can help lower body temperature, there is a widely accepted theoretical explanation. Most sleep experts agree that people sleep better when they are cool. The National Sleep Foundation recommends keeping the ambient temperature between 60 and 67 degrees Fahrenheit while sleeping. However, this is a broad range and depends on the individual, experts say. A 2023 study shows that for older adults, sleep is “most effective and peaceful” when the temperature is between 68 and 77 degrees.
Our bodies also help us stay cool at night. Body temperature — on average around 98.6 degrees Fahrenheit — follows the circadian rhythm and tends to fluctuate slightly throughout the day and night. Research shows that our body temperature is at its lowest around 4 a.m., then gradually rises throughout the day, reaching its peak in the evening before bedtime.
According to medical professionals, sweating can lower body temperature, as can distal vasodilation — a process where small blood vessels under the skin expand, allowing heat to escape. When we warm up our feet by wearing socks, the blood vessels under the skin expand not only in the feet but throughout the body, medical experts claim. This vasodilation allows warm blood to reach the surface, and as it continues to circulate and reach the skin, body heat is released, ultimately causing the internal body temperature to drop. It’s this drop in body temperature that signals the brain to prepare for sleep, specialists conclude.
