Increased Body Temperature01:25

Increased Body Temperature

7.5K
A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Types of Fever

Fever can be triggered by several factors, including infections, nervous system disorders, certain cancers, blood diseases like leukemia, embolism, thrombosis, heatstroke, dehydration, surgical trauma, crushing injuries, and allergic reactions.
Here are the different types of fever:

Methods of reducing fever

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Homeostatic Imbalances in Body Temperature01:19

Homeostatic Imbalances in Body Temperature

4.3K
Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

Summary

Fever can help or harm infection resistance. From a species perspective, fever aids recovery in mild infections but eliminates individuals with severe infections to prevent epidemics.

Area of Science:

  • Immunology and evolutionary biology

Background:

  • Fever and its mediators exhibit dual effects on infection resistance, potentiating or inhibiting it.
  • These contradictory effects are challenging to explain from an individual's survival standpoint.

Purpose of the Study:

  • To reconcile the paradoxical roles of fever in infection resistance.
  • To explore the evolutionary and species-level implications of fever's effects.

Main Methods:

  • Review and synthesis of existing data on fever and infection resistance.
  • Teleological and evolutionary analysis of fever's functions.

Main Results:

  • Fever's effects are plausible when considering species preservation over individual survival.
  • Fever aids recovery in mild/moderate infections, promoting species propagation.

  • Fever eliminates individuals with severe infections, preventing epidemic spread.

    • Conclusions:

    • Fever and its mediators evolved as mechanisms for species survival.
    • Fever balances individual recovery with the elimination of epidemic threats.
