How do you fix your sleep when you share a room with a noisy night owl?

I disonnect the digital devices one hour before atleast. Make the room dark and cool. Apply warm oil on my foot and deep breate for 3-4 minutes

That is definitely hard to do, I used to be that noisy night owl. I suggest trying to communicate with them to be else where around the time you go to sleep.

The best to way is compromisation or to make a healthy boundary.You hafta communicate openly to your roommate and share your consent as politely as possible and in order to make some healthy boundary.

Try a white noise machine to drown out the noise or use earplugs. Earbuds may also work if they have noise canceling or you play soft music or white noise/rain sounds
