CLOCK WATCHING

HOW to harness the power of your bodyclock. This week: Wear socks to bed BED socks can help us fall asleep faster by tricking the body into cooling down.

When the feet are cold, the body produces heat to warm them up; this also warms up the body as a whole. Wearing

socks removes this need and allows body temperature to drop, which is necessary to fall asleep. Meanwhile, cotton and linen are better than man-made fabrics such as polyester at wicking away sweat, which is also important for temperature regulation, says sleep expert Neil Stanley.
