AI Article Synopsis
- Periocular skin warming has been shown to positively impact both perceived and measured sleep quality.
- A study with 18 healthy participants found that using a warming eye mask improved the temperature gradient of the skin and led to faster sleep onset and deeper sleep stages compared to a sham mask.
- The findings suggest that warming the skin around the eyes may help enhance heat loss in the body, promoting quicker and more restful sleep, similar to natural sleep patterns.
Article Abstract
Periocular skin warming was reported to have favorable effects on subjective and objective sleep quality. We hypothesized that enhancing body heat loss by periocular skin warming would reduce sleep onset and improve sleep quality. Eighteen healthy volunteers were asked to maintain wakefulness with their eyes closed for 60 min after applying either a warming or sham eye mask, followed by a 60-min sleep period. Compared to the sham, periocular warming increased the distal skin temperature and distal-proximal skin temperature gradient only during the 30-min thermal manipulation period. In the subsequent sleep period, periocular warming facilitated sleep onset, increased stage 2 sleep and electroencephalographic delta activity during the first half of the sleep period relative to the sham. These results suggest that periocular skin warming may accelerate and deepen sleep by enhancing physiological heat loss via the distal skin, mimicking physiological conditions preceding habitual sleep.
