Introducing my own sleep item
My quality of sleep is so heavily influenced by whether or not I have blackout curtains.
Blackout curtains are really an essential sleep item for my sleep!
I am sensitive to light and sound, but I am especially sensitive to light.
I can't sleep when it's bright, but ever since I started using blackout curtains, I've been sleeping soundly.
Those who truly say their quality of sleep is poor
I strongly recommend you to change the curtains first.
