i sleep with a sleep mask every day, with the curtains open.
(bought this $35 Tempur mask last month.)
it helps me sleep deeply while preventing depression.
Note: i have non-24-hour sleep-wake disorder. i usually never go out.
i reco a sleep mask to everyone.
but idk if its bad for wrinkles.
somnologists reco people sleep with the curtains closed.
(bc the sunrise disturbs ur sleep.)
