Sleeping well is a necessity - 6-8 hours is the suggested amount that we need to allow us to function properly. Every now and then, we can lose a night’s sleep but it can take a while to recover from it, but chronic sleep deprivation isn't so easy to get over. Trouble sleeping affects the sleep of millions around the globe. The worst part of this condition would be that frequently there is no distinct reason for the sleep loss itself. Your bed feels good, it's tranquil, you’re cosy and warm and you don’t really feel anxious, but for some reason you simply are unable to rest.
