Competing Interests

The study was sponsored by airweave (to Ota Memorial Sleep Center). In addition, Drs. Chiba and Nishino occasionally have given lectures on sleep physiology and hygiene for the general audience at educational events supported by airweave. This does not alter our adherence to PLOS ONE policies on sharing data and materials.
