Lack of Sleep

You’ll feel grumpy and tired if you don’t get enough sleep on a regular basis, but it can raise your risk of a heart attack, too. In one study, researchers found that people who usually slept fewer than 6 hours a night were twice as likely to have a heart attack as those who slept 6 to 8. Doctors aren’t sure exactly why this is, but they do know that losing sleep can raise your blood pressure and lead to inflammation. Neither of those is good for your heart.
