    Napping can be a boon to busy professionals who snatch a few winks in the middle of a day to return refreshed to their work, but for people who suffer from insomnia or have nothing much to do by day it can also disrupt their night's sleep.

    The optimum length of a nap is currently said to be a relatively short 15 to 30 minutes, the lightest stage of non-REM sleep that will still revitalize people's energy levels without making them groggy when they wake up.

    A longer sleep taking people to a deeper stage of sleep can make it hard to get back to routine. Certainly napping longer than 90 minutes is not recommended.

    Longer naps can also interfere with a good night's sleep. Those who suffer from insomnia and try to catch up on sleep by taking a nap can enter a vicious cycle.

    If you feel you must take a nap, set the alarm for 15 to 30 minutes. Some people recommend drinking a cup of coffee just before lying down. The effect of caffeine will kick in about half an hour later, helping them to wake up alert.
