My personal sleep item: dark-colored curtains

First, it must be dark in order to sleep well.

Melatonin is secreted well, leading to restful sleep.

It is said that you can get intoxicated.

I forgot where the curtain is.

Using dark-colored curtains to block out the light

I think it's good.

Wouldn't it be better to sleep even better if it's quiet there?

I have some insomnia, but some people use white noise.

I heard that if I leave it on, I sleep well, but I have sensitive ears.

It actually becomes a hindrance.

Dark and quiet seems to be the best.

I look forward to a good night's sleep again today.
