Repeated alarms can have detrimental health impacts, research finds

In a study conducted at the University of Notre Dame, researchers found that people who repeatedly set the alarm to snooze were likely to have a greater heart rate than those who got up immediately when the alarm went off. .
The study indicated that alarm snoozers spent an hour in light sleep before waking owing to repeated alarm disruptions, but those who did not set their alarms to snooze benefited from deeper sleep in the last hour, indicating they had an overall better quality of sleep.

Repeated alarms



A recent study from the same university found that a rapid heart rate may be the reason of the association between poor sleep and cardiovascular disease.
In another study, same researchers found that people who went to bed 30 minutes later than their typical bedtime had increased heart rates throughout the night and occasionally into the next day.

These sleeping habits are also worrisome because elevated heart rate raises the risk of heart disease and diabetes.

It should be remembered that setting the alarm to snooze is an option that turns off the alarm for a brief period of time and starts ringing again after a while.
