Coffee's little secret to stop/slow down the onset of sleep

A cup of coffee in the evening may be keeping you awake for more reasons than you realise, scientists say.

Their study, in Science Translation Medicine, showed caffeine was more than just a stimulant and actually slowed down the body's internal clock.

A double espresso three hours before bedtime delayed the production of the sleep hormone melatonin by about 40 minutes, making it harder to nod off.

"It could be useful with jet lag if you are flying east to west where taking caffeine at the right time of day might speed up the time it takes to overcome jet lag," he added.

I go a step further- I can't sleep if I haven't had a coffee before bed. This "caffeine keeps you awake" caper is an urban myth.

Caffeine will have an effect on sleep quality in everyone, even if you think it doesn't.
