The mechanism of heat loss from the human body is known as thermoregulation.
Thermo-regulation is defined as an important aspect of the homeostasis. The process of
thermoregulation is adjusted by the neuronal regulations of the brain (hypothalamus) in
accordance prevailing external temperature of the environment. There are four different
avenues of heart loss by the process of thermoregulation from the body namely: convection,
conduction, radiation and evaporation (Romanovsky, 2014).
If the temperature of the skin is higher in comparison to the temperature of the
surrounding environment, then the body loose heart by the process of radiation and
conduction. However, if the temperature of the surroundings is higher than that of the skin,
the body gains heart by the process of radiation and conduction. Conduction is defined as a
process of loosing heart from the body by physical contact (contact with another body or
object) like coming in contact with warm blanket helps to increase the temperature of the
body (Tansey & Johnson, 2015). The process of radiation deals with loss of heart through
infrared rays. This deals with transfer of heart from one object to another in the absence of
direct physical contact. Like transfer of heat to earth by the process of radiation obtained
through heat rays of the sun (Tansey & Johnson, 2015).
The temperature of the body increases from the threshold value (normal body
temperature is 36.5 to 37.5 degree Celsius), then the body initiates the process of cooling by
the process of sweating. Sweating leads to the excretion of the sweat (liquid in nature)
through the sweat glands present over the surface of the skin. The sweat that is being excreted
is evaporated either due to the high temperature in the surrounding (summer) or due to dry
climate in the surrounding (in winter). This loss of sweat by the process of evaporation
promoted cooling of the body (Taleghani et al., 2014). Flouris and Schlader (2015) stated that
during intensity exercise activity or during sport, the process of evaporation is the main
approach behind the conduction of thermo-regulation of the body.
