This mode increases the risk of heart attack and hypertension. The specialists gathered about 4,000 people aged 23-90. Of these, those who wake up early became more likely to seek medical assistance with signs of a heart attack.
This is what scientists from Pennsylvania say. When every day a person wakes up early, sacrificing sleep, then her heart is faced with a heavy load. For this reason, Japanese colleagues note, the need to get up early and insecure. It is better to spend more time in bed. Incidentally, this also applies to people who are getting up early in the workout. True, there is a paradoxical moment: among the "larks" more longevity.
But the opportunity to wean in the daytime reduces the load on the heart. As the analysis showed, people who slept in the afternoon three times a week (at least 30 minutes) had a 37% lower risk of death from heart disease.
Daytime sleep reduces the levels of cortisol stress hormones, thereby protecting yourself from heart attacks.
