Los días calurosos o las olas de calor: una división sobre cómo contar las muertes por calor
Science (New York, N.Y.)
|August 29, 2024
Resumen
Centrarse en las temperaturas extremas puede impulsar cambios en las políticas. Sin embargo, este enfoque puede llevar a subestimar el impacto total del cambio climático.
Área de la Ciencia:
- Ciencias del medio ambiente
- Ciencias del clima
- Salud pública
Sus antecedentes:
- El cambio climático presenta diversos riesgos para la salud más allá de las temperaturas extremas.
- Las políticas a menudo se dirigen a eventos de alto impacto como olas de calor y brotes de frío.
- Un enfoque estrecho puede pasar por alto otras cargas significativas para la salud relacionadas con el clima.
Objetivo del estudio:
- Evaluar el impacto de centrarse únicamente en las temperaturas extremas en la política de cambio climático.
- Evaluar la posibilidad de subestimar las cargas sanitarias excluyendo los factores climáticos no extremos.
- Abogar por un enfoque más integral de la adaptación y la mitigación del cambio climático.
Principales métodos:
- Análisis de los datos sobre la temperatura global y los resultados sanitarios asociados.
- Comparación de las estimaciones de la carga para la salud de las exposiciones climáticas extremas frente a las no extremas.
- Revisión de los marcos actuales de la política de cambio climático y su alcance.
Principales resultados:
- Las políticas que hacen hincapié en las temperaturas extremas pueden movilizar la acción.
- Este enfoque corre el riesgo de subestimar significativamente los impactos totales del cambio climático en la salud.
- Los cambios climáticos no extremos pero persistentes contribuyen sustancialmente a la morbilidad y la mortalidad.
Conclusiones:
- Si bien las temperaturas extremas son objetivos políticos críticos, representan solo una fracción de los riesgos para la salud relacionados con el clima.
- Es necesario un enfoque holístico para evaluar y abordar con precisión todo el espectro de los efectos del cambio climático en la salud.
- Las políticas climáticas integrales deben integrar diversos datos ambientales y de salud para una protección efectiva de la salud pública.

01:22Methods of reducing fever
649
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.

01:19Homeostatic Imbalances in Body Temperature
114
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...

01:25Increased Body Temperature
647
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...

01:14Mechanisms of Heat Transfer
290
Heat transfer between the human body and its environment occurs through four main mechanisms: conduction, convection, radiation, and evaporation.
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant...

01:29Decreased Body Temperature
602
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...

02:46Quantifying Heat
54.2K
Thermal Energy Microscopically, thermal energy is the kinetic energy associated with the random motion of atoms and molecules. Temperature is a quantitative measure of “hot” or “cold”, which depends on the amount of thermal energy. When the atoms and molecules in an object are moving or vibrating quickly, they have a higher average kinetic energy (KE) (or higher thermal energy), and the object is perceived as “hot”, or it is described as being at a...
