If you sleep 75 more minutes, move more intensely for 12.5 extra minutes, and eat a bit healthier each day, you might cut your risk of dying from any cause in half—especially if you're middle-aged or older.

If you sleep 15 minutes longer, move a bit more, and eat a little healthier—like adding half a serving of veggies or skipping one piece of processed meat a week—your risk of dying from any cause might drop by 10%. Small changes together could make a big difference for your health.

People who sleep just the right amount, exercise moderately to vigorously, and eat well are 64% less likely to die from any cause compared to those who don’t do any of those things well — especially if they’re middle-aged or older.

People who sleep less than 7 hours a night are more likely to develop heart problems or die from them compared to those who sleep 7 to 9 hours, based on wearable device data.

People who sleep more than 9 hours a night don’t seem to have a higher chance of heart problems or dying from heart issues than those who sleep 7 to 9 hours, at least based on how their sleep was tracked with a wrist device.

If you sleep less than 7.7 hours a night, the less you sleep, the higher your body mass index (BMI) tends to be — for example, people who sleep 5 hours have a 3.6% higher BMI than those who sleep 8 hours, even when you account for their age, gender, or breathing issues during sleep.
