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.
Na+ and K+
balance is lostH2O is lostNa+ is lost
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
