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.
