Heat exhaustion results due to accumulation of large quantities of blood in the skin as a part of cooling mechanism in case of very high external temperature.

Due to the accumulation of blood in the peripheral system, the blood supply gets lowered centrally i.e the blood supply to the heart and brain gets decreased. Due to this fainting may result. Other symptoms may include profused cold perspiration and unusual pallor (reduced oxyhaemoglobin or paleness). The pulse rate may be weak and breathing may be shallow.
