Heat exhaustion & heatstroke

Hyperthermia et ictus solis · Vyčerpání z horka a úpal

What it is

Thermoregulation fails; above about 40 °C core temperature, cells and organs start to fail.

Symptoms & signs

  • Heavy sweating then no sweating
  • dizziness
  • nausea
  • confusion
  • hot skin, dry or still sweating
  • collapse
  • seizures

🚩 Get help if…

  • call 112 / 911 now Hot skin with confusion, odd behaviour, fits or collapse
  • call 112 / 911 now Body temperature 40 °C or higher
  • see a doctor soon Not better after 30 minutes of cooling and drinking
  • see a doctor soon Vomiting and cannot keep fluids down

Where it strikes

Medical treatment

  • Rapid cooling by cold-water immersion (first priority)
  • IV fluids
  • monitor for rhabdomyolysis and kidney failure
  • ICU care

Natural & lifestyle

  • Acclimatise gradually
  • hydrate and salt
  • avoid midday exertion
  • light clothing
  • check on vulnerable neighbours

Emerging & experimental

  • Cooling vest technology
  • pre-cooling protocols for athletes

Alternative, off-label & anecdotal

Approaches used outside the guidelines, with what their supporters report and what testing has found so far.

  • Ice-slurry drinks before exertion — trials lower core temperature mixed evidence
  • Ice packs to the neck and armpits alone — much slower than cold-water immersion anecdotal / traditional
