If you routinely hit the snooze button, it might be a sign you are “chronically tired,” according to a new study published in the journal Sleep. Researchers at Notre Dame found that people who use an alarm to wake up feel more groggy than those who wake up naturally. They observed that people who wake up naturally without an alarm sleep longer and drink less caffeine in the day. They are also less likely to feel tired during the day. When we wake up naturally, our bodies experience a stress response just to make us feel alert. Using an alarm appears to bypass this stress response and interrupt our sleep cycles. Close to three in five adults hit the snooze button each morning.
