Skin temperature, sleep, and vigilance [PDF]

open access: yes, 2018
A large number of studies have shown a close association between the 24-hour rhythms in core body temperature and sleep propensity. More recently, studies have have begun to elucidate an intriguing association of sleep with skin temperature as well. The present chapter addresses the association of sleep and alertness with skin temperature. It discusses

Core Temperature in Triathletes during Swimming with Wetsuit in 10 °C Cold Water

open access: yesSports, 2019
Low water temperature (<15 °C) has been faced by many organizers of triathlons and swim-runs in the northern part of Europe during recent years. More knowledge about how cold water affects athletes swimming in wetsuits in cold water is warranted.
