The baby boy, who was just a week old and still had his umbilical cord attached, was found in a plastic bag where the temperature had reached over 30°C.
Paramedics had to provide minimal medical intervention before handing him over to the relevant department. The baby, however, showed no signs of sunstroke, which is the biggest killer in similar situations.
Sunstroke: the facts
Sunstroke can be fatal if not properly treated. Once the body's cooling mechanism fails, the core temperature rises rapidly and death can occur in as little as 30 minutes. Some people die up to several weeks after the initial acute episode as a result of complications such as kidney failure or heart failure. Sunstroke kills over 10% of its victims. Sunstroke may also cause permanent damage to organs such as the liver.
In a hot environment, your body rids itself of excess heat through increasing blood flow to the skin, sweating and breathing out warmed air. These mechanisms can sometimes be overwhelmed, however, leading to heat-related symptoms, which, if left untreated, can lead to sunstroke.Read
: Beware of dehydration this summer
When blood temperature rises above its normal range, a control centre in the brain (the hypothalamus) signals the circulatory system to increase blood flow and enlarge the blood vessels, particularly those in the skin. As more blood flows through the enlarged vessels, excess heat from the blood passes into the cooler air. If this is not sufficient to cool the blood, the sweat glands begin to produce sweat, which cools the skin as it evaporates.
If the air temperature is very high, however, the blood may not cool down enough as it circulates through the skin. Also, when you lose too much fluid, the blood volume decreases, and body temperature rises. If the body continues to generate heat faster than it can be dissipated, the core temperature (central body temperature) may rise to dangerous levels.
Sunstroke usually occurs when working in an extremely hot environment, especially one to which you are unused; exercising too strenuously, particularly in summer; or when you have a high fever associated with illness. Read
: Be wise in the sun
Humid weather also renders the cooling mechanism of sweating less effective. Overdressing, overeating and drinking too much alcohol can be contributing factors.
