It's got to be one of the most frustrating things, a lack of sleep. You feel tired at work, tetchy with colleagues, friends and family members. You know you're not getting enough sleep but that knowledge in itself doesn't help much.
People can end up worrying too much about sleep - something that, as anyone familiar with that empty feeling as you toss and turn in your bed late at night, just makes the problem worse. It can even make some people actually fear going to bed, knowing what's waiting.
The recommended amount of sleep the average adults needs each night is often said to be about eight hours. Sometimes, however, even if you manage to get those hours in - you still feel tired and lethargic. What could the cause possibly be, and how do you address it?
