Sleep - or lack of it - is one of the most common 21st century health complaints. Only 1 in 10 of us say we always sleep well; 1 in 5 suffer from lack of sleep; and two thirds say we get less sleep now than we did a few years ago - around 90 minutes less, according to one leading American sleep expert.

There are many different views as to how much sleep we need - eight hours is often quoted, but some of us need less; and some more. The simplest answer is enough sleep to feel refreshed in the morning and stay awake and alert throughout the day.

If lack of sleep is a problem - what should you do about it? Do you realise that often the solution lies in our own hands and simply requires some simple changes to our sleep environment and lifestyles - probably even less arduous than going on a diet to lose weight, although, like a diet, it might take a few weeks to get into the habit of new habits.
