Recently, thanks to Nic who recommended a sleep mask to me, my sleeps have been much more restful. Living in a condo, there is a lot of city light that subconsciously woke me up throughout the night. And in the mornings, I would be blasted with sunlight. I noticed on my sleep performance on WHOOP I was awake for close to 10% of my sleep, which seemed quite high.
Since using a sleep mask consistently every night I’ve noticed 2 major changes.
1. The initial complete darkness has helped me fall asleep faster.
2. I am sleeping for more time (on average) and on my WHOOP my time awake has gone down from 10% to 3-5%.
Now it feels weird sleeping without a sleep mask. I don’t think I’ll ever go back to sleeping without one on. I recommend everyone to wear a sleep mask. It has supremely helped my sleep and recovery.
