Periocular skin warming promotes body heat loss and sleep onset: a randomized placebo-controlled study

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 wakefulne...
