How to practice Keep feet warm
Wear loose, breathable socks or use a warm foot bath 10–20 minutes before bed. Avoid tight garments or electric heating pads that overheat. Combine with a cool bedroom for optimal temperature gradient. Discontinue if overheating or restlessness occurs.
The evidence behind Keep feet warm
Warming extremities increases blood flow and heat loss from the core, aiding sleep onset. Controlled studies show that wearing socks reduces sleep latency by 10–20 minutes and increases total sleep time. Mechanism: peripheral warming accelerates the body’s natural thermoregulatory drop required for sleep initiation. Evidence moderate and consistent.
