Spring fatigue has arrived, and even those who need less sleep than others are gripped by listlessness and a drop in motivation. The answer may be a brief catnap, which experts say can help recover from fatigue and boost efficiency at work.
Human sleeping patterns repeat according to a certain biorhythm, and people generally feel the greatest urge to sleep in the early morning and in the early afternoon roughly eight hours after they wake up.
Thus someone who wakes up at 6 a.m. will feel most sleepy at 2 p.m. That is the best time for a nap. Napping after 4 p.m. is best avoided as it may cause trouble falling asleep at night.
A 15 to 30-minute nap is enough. People should wake up while they are in light sleep in order not to feel too drowsy afterwards. Normally, 15 minutes are ideal, but for older people who have trouble falling asleep, a 30-minute nap is fine.
