How Sleep Affects Your Heart Rate

Sleep Affects Heart Rate

We all know that sleep deprivation is unhealthy but a new study suggests, what time of day you sleep also plays a key role. Researchers examined 26 adults between 20 and 39 years old for eight days, the volunteers were only allowed five hours of sleep.

Half of the volunteers slept during the day and half slept at night. At the end of the study, both groups had increased heart rates during the day. This is especially bad news for the people who slept during the day. Normally, heart rate slows during the most restorative stage of sleep.

Since this wasn't the case for day sleepers, it suggests they couldn't fully recover. The study itself is small, but its results support similar findings. past studies have found that shift workers suffer a higher risk of heart attack.

The researchers suggest that their results help explain why. Adults need seven to eight hours a day of sleep.
