The Exact Time You Should Go to Sleep, according to Science

This study, published in the European Heart Journal – Digital Health, found that your bedtime can play a role in your risk for developing cardiovascular disease.

To come to this conclusion, researchers collected sleep data from the study’s participants over a period of seven days. Then, during an average follow-up period of 5.7 years, researchers noted which participants developed cardiovascular diseases.

Other research also points to the importance of sleep timing in relation to your heart health. A study published in the Journal of the American Heart Association earlier this year found that participants who went to bed past 11 p.m. and slept later than 8 a.m. were at a higher risk for congestive heart failure…
