Do you envy people who can drop off to sleep in the middle of the day? Research suggests that taking regular ‘naps’ may help reduce stress, and experts say it also increases your energy levels and helps you think more clearly.
Sleeping for different lengths of time can have different benefits. But the idea behind a ‘power nap’ is that you don’t sleep for very long – just 15 to 30 minutes – so that you stay in the ‘light’ stage of sleep.
This is because if you sleep for more than 30 minutes, you’ll start entering the ‘deep’ stage of sleep – which can make you feel groggy when you wake up. If you sleep for 90 minutes, you’ll have completed an entire sleep cycle and will feel more rested – but most of us don’t have time for a nap this long.
So how should you power nap? Try to do it at the same time every day (early afternoon is good) and set an alarm so you don’t have to worry about over-sleeping.
