Sleep your way slim.

Early to bed, early to rise,
Makes a man healthy, wealthy, and wise!

Stay up late, get up too early,
Gives a man baggy eyes, a foul mood,
and maybe extra body fat!

The first paragraph is an age-old rhyme, but the second, surprisingly enough, is the result of scientific research carried out on volunteers in two separate sleep studies, as reported in The Scotsman today.

Chronic lack of sleep could be one reason people are getting so broad in the beam, suggest the authors of two new studies. Their research found that going without sleep seems to elevate blood levels of a key appetite-stimulating hormone, ghrelin. It causes levels of a "stop eating" hormone, known as leptin, to take a dive. The likely net effect is an increase in appetite. It appears that the hunger-inducing powers of sleep deficits - i.e. the craving for salty, fatty food and the resulting extra weight that this puts on does not conversly prove that getting extra sleep will help shed extra weight!

Seems like a no-win situation, but either way getting a good nights sleep will certainly help your body through the daily rigours of life.
