=== Hyperthermia ===
Humans use sweat thermoregulation for body heat removal, particularly to remove the heat produced during exercise. Moderate dehydration as a consequence of exercise and heat is reported to impair cognition.<ref>{{Cite journal |last=Baker |first=LB |last2=Conroy |first2=DE |last3=Kenney |first3=WL |year=2007 |title=Dehydration impairs vigilance-related attention in male basketball players |journal=Medicine & Science in Sports & Exercise |volume=39 |issue=6 |pages=976–83 |doi=10.1097/mss.0b013e3180471ff2 |pmid=17545888 |s2cid=25267863 |doi-access=free}}</ref><ref>{{Cite journal |last=Cian |first=C |last2=Barraud |first2=PA |last3=Melin |first3=B |last4=Raphel |first4=C |year=2001 |title=Effects of fluid ingestion on cognitive function after heat stress or exercise-induced dehydration |journal=International Journal of Psychophysiology |volume=42 |issue=3 |pages=243–51 |doi=10.1016/S0167-8760(01)00142-8 |pmid=11812391}}</ref> These impairments can start after body mass lost that is greater than 1%.<ref>{{Cite journal |last=Sharma |first=VM |last2=Sridharan |first2=K |last3=Pichan |first3=G |last4=Panwar |first4=MR |year=1986 |title=Influence of heat-stress induced dehydration on mental functions |journal=Ergonomics |volume=29 |issue=6 |pages=791–9 |doi=10.1080/00140138608968315 |pmid=3743537}}</ref> Cognitive impairment, particularly due to heat and exercise is likely to be due to loss of integrity to the blood brain barrier.<ref name="Maughan, R.
