Response to hyperthermia:
1. Behavioural
Activities to cool down (move into shade, jump into river)
2. Non-behavioural
Think about physiological changes required to meet the increased metabolic demand.
CVS
- Increased cardiac output (tachycardia)
- Peripheral vasodilation
- Sweating
Respiratory
- Increased gas-exchange (tachypnoea)
CNS
- decreased seizure threshold
Cellular
- Altered enzyme function
- Tissue damage
