Hitting snooze repeatedly may fragment your sleep, worsen morning grogginess and affect your mood and focus—here’s why one alarm and better sleep may be the smarter approach

For many people, mornings begin with the sound of an alarm. Then comes another one. And another. You may tell yourself that five more minutes will help you feel more rested, but after several rounds of snoozing, you finally get out of bed feeling even more tired. This habit is common, especially among people who struggle to wake up early. But repeatedly going back to sleep after an alarm may not give your body the proper rest it needs. Instead, it can leave you groggy, confused, and slow to get started.

Dr. Dhiraj Jain, Consultant Pulmonologist & Sleep Medicine Specialist, explains, “Repeatedly hitting snooze can fragment sleep and disrupt important stages like REM sleep, affecting memory, mood, and mental clarity. Maintaining a consistent wake-up time and getting up with the first alarm can support better sleep and morning alertness.”

Here are five reasons your multiple alarms may be leaving you more tired.
