Bad night's sleep? Study says don't start your day with coffee

BATH, United Kingdom -- Drinking coffee before breakfast after a bad night's sleep could be bad for your health, according to a new study.

Researchers at the University of Bath in the United Kingdom studied the combined impacts of broken sleep and morning coffee.

Specifically, they were looking at the effect on a person's metabolism.

Their findings suggest that drinking strong, black coffee after disrupted sleep has a negative impact on blood sugar control.

Elevated blood sugar levels increase the risk of conditions like diabetes and heart disease.

The take-away was that if you don't sleep well, you should drink coffee after breakfast, not before.
