I have an oxygen box at home, and I thought it would be nice to be able to put it in my room at home with 1.2 tatami mats, so I started using it. Before I started using it, I was chronically sleep deprived, which weakened my mind and body. However, these days, I am feeling lighter both physically and mentally, and I am able to spend every day in the best mood! Even if you just take 5 or 10 minutes a day, I think it's completely different.
