Going to bed early may be a warning sign you have serious heart problems, experts have warned.
New research presented at the world's biggest heart conference in Rome found those who chose to turn in sooner were more likely to be suffering with high blood pressure.
They also had a greater chance of suffering a worse night’s sleep.
Experts said although the study showed getting tired early could be a key warning sign that you have high blood pressure, it also suggested going to bed early would not help lower it.
High blood pressure, or hypertension, rarely has noticeable symptoms. But if untreated, it increases your risk of serious problems such as heart attacks and strokes.
Professor Jeremy Pearson, Associate Medical Director at the British Heart Foundation, said: “This study indicates that people with known high blood pressure may go to bed a few minutes earlier than those with normal blood pressure, and the quality of their sleep may be slightly worse.
“People often have raised blood pressure without knowing it. You should check your blood pressure regularly and see your GP if you are concerned.”
