Increased Body Temperature01:25

Increased Body Temperature

2.7K
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...

Methods of reducing fever

784
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.

Decreased Body Temperature01:29

Decreased Body Temperature

724
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Homeostatic Imbalances in Body Temperature01:19

Homeostatic Imbalances in Body Temperature

319
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

Extreme heat is linked to more emergency department visits for adults in the USA. This study highlights the health risks associated with high ambient temperatures.

Area of Science:

  • Environmental Health
  • Public Health
  • Epidemiology

Background:

  • Elevated ambient temperatures pose significant risks to human health, contributing to increased mortality.
  • Previous research indicates a correlation between heatwaves and adverse health outcomes.

Purpose of the Study:

  • To investigate the association between extreme heat and emergency department (ED) visits among adults in the United States.
  • To quantify the impact of high ambient temperatures on healthcare utilization.

Main Methods:

  • Retrospective analysis of emergency department visit data from adults in the USA.
  • Correlation analysis between daily ambient temperature records and ED visit counts.

Main Results:

  • A significant association was observed between extreme heat events and an increase in adult ED visits.
  • The study identified a clear trend of rising healthcare-seeking behavior during periods of high ambient temperatures.

    • Conclusions:

    • Extreme heat is a critical public health concern associated with increased demand for emergency medical services.
    • Findings underscore the need for public health interventions and adaptive strategies to mitigate the health impacts of rising global temperatures.
