Cold-induced vasodilation responses before and after exercise in normobaric normoxia and hypoxia

Wilderness Medical Society Clinical Practice Guidelines for the Prevention and Treatment of Frostbite: 2024 Update

“…16 An additional study demonstrated the CIVD response may be negatively affected by the introduction of hypoxia, whereas metabolic heat production via exercise may counteract adverse effects of hypoxia and improve CIVD responses. 17 However, using exercise to increase warmth can lead to exhaustion, with subsequent profound systemic heat loss should exhaustion occur. Recognizing this caveat, exercise and its associated elevation in core and peripheral temperatures may be protective in preventing frostbite.…”

Sensitivity of cognitive function tests to acute hypoxia in healthy subjects: a systematic literature review

“…Eighteen studies were performed in a hypoxic chamber (Asmaro et al, 2013;Kim et al, 2015;Seo et al, 2015;Lefferts et al, 2016;Legg et al, 2016;Valk et al, 2016;Beer et al, 2017;Feeback et al, 2017;Seo et al, 2017;Decroix et al, 2018;Reményi et al, 2018;Gerhart et al, 2019;Williams et al, 2019;Seech et al, 2020;Blacker and McHail, 2021;Blacker and McHail, 2022;Chroboczek et al, 2022;Falla et al, 2022;Kerr et al, 2022), 16 with a breathing mask that induced hypoxia (Turner et al, 2015a;Noble et al, 1993;Ochi et al, 2018;Malle et al, 2016;Lei et al, 2019;Caldwell et al, 2018;Hewett et al, 2010;Legg et al, 2012;Ogoh et al, 2018;Stepanek et al, 2013;Nakata et al, 2017;Loprinzi et al, 2019;Kourtidou-Papadeli et al, 2008;Turner et al, 2015b), two studies were performed at altitude (Wang et al, 2013;Davranche et al, 2016), one both at altitude and in a chamber (Kammerer et al, 2018), and one both in a chamber and with a breathing mask (Rossetti et al, 2021). The exposure duration ranged from 10 min to 6.5 h with 92% of studies using durations of <3 h. The data points obtained were divided into exposure to normobaric hypoxia (133; 67%) and hypobaric hypoxia (66; 33%).…”
