My personal sleep item; Chang'anai blackout blinds + Yoga Boy sleep induction meditation

Dark curtains are essential for sleep.

I am using the Chang'anai blackout blinds installed satisfactorily.

On days when you have trouble falling asleep, play the Yoga Boy Sleep Induction Meditation Video for 15 minutes with auto-shutdown.

I fall asleep immediately after listening for about 10 minutes^^

Highly recommend Yoga Boy's collection; there are many sleep meditations, so choose the one that suits you.
