Sort out the sleep ‘hygiene’

We all know that a balanced diet and plenty of regular physical activity are cornerstones of a healthy lifestyle. But what about sleep? Evidence is mounting that the amount and quality of sleep you get is also a key factor.

It's pretty obvious in the short term that if you miss out on sleep (maybe there's a new baby in the house, you're travelling or there is an exam on the horizon) it can make you a bit irritable. But in the longer term poor sleep is also linked with a higher risk of obesity and even heart disease.

Practising good so-called sleep 'hygiene' can help ensure you get that all important restful slumber. The National Sleep Foundation in the US offers some tips here as well as some tips on making your bedroom a sleep-friendly environment.
