IN SUMMARYIN HIGH ENVIRONMENTAL TEMPERATURES (ABOVE 25oC AND R. HUMIDITIES ABOVE 40%)

HOMEOSTASIS BEGINS TO FAIL ANDHEAT STRESS COMMENCES

As heat stress progresses, deep body temperature rises: for every 1oC rise, metabolic rate increases 20-30%. The temperature rise is detected in the hypothalmus which initiates behavioural and physiological responses as shown below.

PANTINGCools the body by

EVAPORATIVE COOLING(loss of H2O) from the lungs"x" mLs H2O = "x" calories

of HEAT

SHUNTS BLOODSPREADS WINGSTo radiate heatfrom body to

ground

STOPS EATING ANDDRINKS MORE (2x)

To lower production ofMETABOLIC HEAT and to cool body via the gut Away from gut to

reduce productionof METABOLIC HEAT

To comb to increaseheat loss

URINE EXCRETIONis increased due to less anti-diuretic hormone being secreted

ACID/BASE BALANCE IS LOSTand thus the control of allreactions within the cells.

This leads to at least 25% lossof productivity.

RESPIRATORY RATE

(from 20-250/minute)

Respiratory Alkalosis whereCO2 and HCO3 are lost

Plasma pH upto 8.0 (or so)

Intracellular pH to acid where K+ is lost

IT IS ESSENTIALTO RESTORE ELECTOLYTE Na+ : K+ : HCO3

- TO ENHANCE INTRACELLULAR RECOVERY

TO PROVIDE COOL DRINKING WATER

OTHERWISE ENZYME AND COENZYME REACTIONS (PRODUCTIVITY) WILL NOT RECOMMENCE

The answer lies in the use of ANIGANE and SELECTOLYTE
