A 10-minute evening skincare massage may help women sleep better and feel less anxious

Four weeks of a 10-minute evening cosmetic routine with self-massage improved self-reported sleep quality, state anxiety, mental health, and vitality in women with sleep complaints compared with usual routines. Exploratory wearable data showed longer total and deep sleep on rest days, but the non-randomized design and absence of wearable controls limit causal conclusions.

Wearable forehead patch tracks brain-water shifts during sleep at home

A soft, wireless NIRS forehead patch tracked water-sensitive brain signals during 16 overnight home sleep recordings in four healthy men. The signals changed with EEG/EOG-defined sleep stages, suggesting a new way to study sleep-linked brain-fluid dynamics, although the device did not directly measure CSF flow or glymphatic clearance.
