“…Additionally, rewarming after cold exposure was not impaired after 2 days of sleep loss with energy restriction and exhaustive exercise. The current study therefore extends previous research that reported rewarming was not affected by 2 nights of sleep loss only (Esmat et al 2012). One important additional distinction between the current and previous sleep loss and cold thermoregulation studies is that participants in this study completed exhaustive daily exercise, whereas previous study participants completed only low levels of physical activity.…”

PurposeIn persons completing exhaustive daily exercise, sleep and energy restriction have been highlighted as risk factors for hypothermia in cold environments. The present study therefore sought to determine the effect of sleep deprivation (SDEP), with and without energy restriction, on the thermal response to cold. MethodsIn a random order, ten recreationally active men (means ± SD: age 25 ± 6 y, body fat 17 ± 5%) completed CAT Tre (P = 0.78). In contrast, perceived thermal discomfort during the initial hour of the CAT tended to be greater after SDEP and SDEP+ER (P ≤ 0.1). ConclusionSleep and energy restriction, at least as evaluated within this experiment, should be considered minimal risk factors for hypothermia. The greater perception of cold discomfort at the same body temperature suggests that sleep and energy restriction may actually reduce cold injury risk, as people are likely to engage earlier in normal behavioural cold adaptation.

Exposome factors that lead to stressed skin can be defined as any disturbance to homeostasis from environmental (meteorological factors, solar radiation, pollution or tobacco smoke) and/or internal exposure (unhealthy diet, hormonal variations, lack of sleep, psychosocial stress). The clinical and biological impact of chronic exposome effects on skin functions has been extensively reviewed, whereas there is a paucity of information on the impact of short‐term acute exposure. Acute stress, which would typically last minutes to hours (and generally no more than a week), provokes a transient but robust neuroendocrine‐immune and tissue remodelling response in the skin and can alter the skin barrier. Firstly, we provide an overview of the biological effects of various acute stressors on six key skin functions, namely the skin physical barrier, pigmentation, defences (antioxidant, immune cell‐mediated, microbial and microbiome maintenance), structure (extracellular matrix and appendages), neuroendocrine and thermoregulation functions. Secondly, we describe the biological and clinical effects on adult skin from individual exposome factors that elicit an acute stress response and their consequences in skin health maintenance. Clinical manifestations of acutely stressed skin may include dry skin that might accentuate fine lines, oily skin, sensitive skin, pruritus, erythema, pale skin, sweating, oedema and flares of inflammatory skin conditions such as acne, rosacea, atopic dermatitis, pigmentation disorders and skin superinfection such as viral reactivation. Acute stresses can also induce scalp sensitivity, telogen effluvium and worsen alopecia.

“…Thus, 53 h of TSD exacerbated thermal discomfort during the initial 1 h of a 4 h exposure to 0 • C air; a response that was independent of any TSD-driven variation in the whole-body thermal state of subjects (Oliver et al, 2015). Such a thermoperceptual sensitization, however, is not supported by other cold-relevant studies (Costa et al, 2010;Esmat et al, 2012;Landis et al, 1998). Conflicting findings have also been obtained during whole-body heat stress.…”

“…Of interest is the work of Oliver et al (2015) and Costa et al (2010), who, by using a within-subject design, found that 53 h of TSD combined with or without negative energy balance neither perturbed thermoeffector capacities (Oliver et al, 2015) nor modulated the immune reactions (the suppression of circulating lymphocytes, neutrophil degranulation and saliva secretory immunoglobulin A) evoked by acute cold (0 • C air) stress (Costa et al, 2010). Lastly, the rewarming response after a period of whole-body cooling does not appear to be disturbed by TSD (Esmat et al, 2012;Oliver et al, 2015).…”

Relatively short periods of inadequate sleep provoke physiological and psychological perturbations, typically leading to functional impairments and degradation in performance. It is commonly accepted that sleep deprivation also disturbs thermal homeostasis, plausibly enhancing susceptibility to cold-and heat-related illnesses.Herein, we summarize the current state of human-based evidence on the impact of short-term (i.e., ≤4 nights) sleep deprivation on autonomic and behavioural thermoeffectors during acute exposure to low and high ambient temperatures. The purpose of this brief narrative review is to highlight knowledge gaps in the area and stimulate future research to investigate whether sleep deprivation constitutes a predisposing factor for the development of thermal injuries.

Fifty-Three Hours of Total Sleep Deprivation Has No Effect on Rewarming From Cold Air Exposure

Abstract: Under the conditions of the present study, sleep-deprived persons are not at a greater risk for a decline in rectal temperature (ie, a hypothermic afterdrop) during rewarming from cold air.
