‌Hyperpyrexia is a condition where the body temperature goes above 106.7 degrees Fahrenheit (41.5 degrees Celsius) due to changes in the hypothalamus — the organ in the brain that regulates temperature.‌ Hyperpyrexia is a life-threatening emergency that demands urgent medical attention.

Who is at risk of Hyperpyrexia?

The very young and elderly: Seniors (over 65) and children (especially those under the age of 4) are often more at increased risk of heat-related illness, as they typically tend to less aware of temperature changes and their bodies generally don’t regulate as well.

Does high fever affect brain?

Brain damage from a fever generally will not occur unless the fever is over 107.6°F (42°C). Untreated fevers caused by infection will seldom go over 105°F (40.6°C) unless the child is overdressed or in a hot place.

What causes rigor?

Rigors are triggered by the presence of chemicals called pyrogens in the blood which ‘turn up’ the body’s thermostat setting, telling the body to aim for a higher target temperature. Pyrogens are produced by our own immune systems in response to certain triggers, of which infection is the most common.

What happens when the body temperature rises above normal?

When the body core temperature rises above the critical level of 37 C (98.6 F), there is an increase in the rate of heat loss by sweating. Shivering and chemical thermogenesis are strongly inhibited.

How does hyperthermia affect the body?

Heat stroke occurs when someone’s body temperature increases significantly (generally above 104 degrees Fahrenheit) and has symptoms such as mental status changes (like confusion or combativeness), strong rapid pulse, lack of sweating, dry flushed skin, faintness, staggering, or coma.

As hyperpyrexia is caused by another disease, treating the latter will usually cause the body’s temperature to go down.

Can hyperpyrexia cause brain damage?

If the fever is not treated and a person’s temperature brought down to a safe level, hyperpyrexia can cause permanent brain damage or death. However, in most circumstances, correct treatments can lower the fever safely, giving doctors time to diagnose and treat the underlying cause of the hyperpyrexia.

Can hyperpyrexia cause high fevers?

Fevers, including very high fevers, are never illnesses in themselves, or the causes of illnesses. Instead, they are symptoms of other problems, such as an infection or injury. Viral or bacterial infections cause most fevers. However, in hyperpyrexia, that is not always the case.
