The sunlight is nice...

In order to have a good sleep, there are several things we should take note.

One of those is the sunlight.

Exposure to sunlight leads to earlier melatonin onset.

Which makes it easier to fall asleep, improving the quality of one's sleep...

...Ever since I heard them say that on TV, I can't help but sunbathe when the sun is strong.

This is nice.

Ah, Susumu-sensei.
