Japan is tackling the sleep issue from many angles to help people overcome “sleep debt” — being owed more sleep than you get. But sleep is deeply personal, and a product that works for one person may not for another.
Experts warn that many products in Japan’s booming sleep tech market have not gone through rigorous scientific testing to prove they actually improve sleep. And because sleep patterns vary individually, it’s difficult to verify which products are most effective for a wide range of people.
At its core, experts say, getting better sleep is about the basics: low lighting, comfortable temperature and no noise.
And those simple steps transcend borders — no gadget required.
