A new study of a hunter-gatherer community in Tanzania has found that how humans rest may affect their risk for heart disease. The study, published in the journal *Current Biology*, found that the Hadza people, who live a traditional hunter-gatherer lifestyle, have a much lower risk of heart disease than Westerners. The researchers believe that this difference may be due to the Hadza's unique sleep patterns.

The Hadza sleep in short bouts throughout the day and night, rather than in one long block like most Westerners. This means that they wake up more frequently, which may help to keep their blood pressure and cholesterol levels in check. The researchers also found that the Hadza have a lower body mass index (BMI) and a higher level of physical activity than Westerners. These factors may also contribute to their lower risk of heart disease.

The study's findings suggest that our modern lifestyle, with its emphasis on long work hours and sedentary behavior, may be contributing to our high rates of heart disease. By adopting some of the Hadza's sleep habits, we may be able to reduce our risk of this deadly disease.

Here are some tips for getting a better night's sleep:

* Go to bed and wake up at the same time each day, even on weekends.

* Create a relaxing bedtime routine.

* Make sure your bedroom is dark, quiet, and cool.

* Avoid caffeine and alcohol before bed.

* Get regular exercise, but not too close to bedtime.

* See a doctor if you have trouble sleeping.

By following these tips, you can improve your sleep quality and reduce your risk of heart disease.
