10 Tips to stop oversleeping

If you have been experiencing the symptoms of oversleeping, try the below tips for how to stop oversleeping. However, if you are sleeping for 12 hours a day or more, visit your doctor for the right oversleeping cure. 

Have A Routine 

A simple trick you must follow to rectify oversleeping is to create a bedtime routine for yourself where you have a consistent sleep-wake time. It helps your body get accustomed to this schedule. You can also include a good sleep hygiene routine to get into the zone before you doze off, such as a warm bath, meditation, listening to soothing music, and more. Also, make sure you avoid any stimulants. 

Drink Coffee 

Try drinking a cup of coffee as soon as your alarm goes off. When you sip on your morning coffee or chai, the caffeine present in them can make you feel less tired or sleepy. 

Don’t Hit The Snooze Button 

If you tend to sleep a lot, then chances are you hit snooze as soon as your alarm goes off. When you snooze and go back to sleep, it can make you feel tired and less productive. And without an alarm, you may end up sleeping all day. Therefore, you can try placing your alarm away from you. 

Get As Much Daylight As Possible 

As soon as you wake up, open the curtains of your bedroom or go out in the sun. This helps stabilise your body’s inner biological clock, known as circadian rhythm. 

Ask For Help 

If you cannot wake up on time, you can always ask your partner, roommate or family member to wake you up at a particular time. Doing it regularly will soon become a habit. 

Say No To Naps 

Sleeping too much, even in breaks, can make you feel more tired. Therefore, if you are sleepy during the daytime, opt for other methods to keep you awake, such as going for a walk, drinking coffee, or keeping yourself hydrated. 

Keep A Sleep Diary 

If you are a chronic oversleeper, you must keep a sleep diary. It helps you record your sleep and wake timings and lets you track your sleep quality. 

Avoid Blue Light Before Bed 

Keep your electronics away at least 30 minutes before bed as the blue light emitted can interfere with your sleep. Even if you enjoy reading before bed, try to avoid phones. 

Maintain Routine Even On Weekends 

It is essential that you avoid oversleeping on weekends or holidays as this could contribute to Sunday night insomnia. It is when you experience sleeplessness every Sunday night due to oversleeping. 

Speak To A Specialist 

If nothing works for you, speak to a healthcare professional, as oversleeping can be a symptom of depression. 

Oversleeping once in a while when you are exhausted is okay. However, sleeping more than 9 hours daily can negatively affect your health. Try to rectify your sleep routine on your own. But if it doesn’t work, make sure you visit your doctor.

Conclusion
