Resumen

Se identifican las poblaciones vulnerables que se enfrentan a riesgos de mortalidad por temperatura, siendo la edad y el sexo factores clave. Esta investigación ayuda a desarrollar estrategias específicas para mitigar los impactos en la salud del clima extremo y el cambio climático.

Área de la Ciencia:

Epidemiología ambiental
Salud pública
Adaptación al cambio climático

Sus antecedentes:

Comprender la vulnerabilidad de la población a las asociaciones de temperatura y mortalidad es crucial para la salud pública.
Los fenómenos meteorológicos extremos y el cambio climático suponen importantes riesgos para la salud.

Objetivo del estudio:

Revisar y evaluar sistemáticamente la vulnerabilidad a las asociaciones entre temperatura y mortalidad.
Identificar los factores individuales y comunitarios que modifican estas asociaciones.

Principales métodos:

Una revisión sistemática de 207 estudios basados en la población publicados entre 1980 y 2017.
Resumen de los hallazgos sobre la modificación del efecto por las características individuales y comunitarias.

Principales resultados:

Fuerte evidencia de la modificación del efecto por factores individuales como la edad y el sexo.
Evidencia limitada para otros factores individuales (educación, raza, condiciones crónicas) y factores comunitarios (estado socioeconómico, aire acondicionado, espacio verde).
Evidencia débil de factores a nivel comunitario como la densidad de población y la contaminación del aire.

Conclusiones:

Los hallazgos proporcionan evidencia para dirigirse a poblaciones específicas en el desarrollo de estrategias contra temperaturas extremas.
Informa las políticas de salud pública para la adaptación y la mitigación del cambio climático.

Palabras clave:

Factors Affecting Body Temperature

Factors Affecting Body Temperature

As a nurse, it is vital to understand the factors affecting body temperature to monitor variations and effectively evaluate deviations from regular.
Factors may include:

Effect of Temperature Change on Reaction Rate

Effect of Temperature Change on Reaction Rate

The Arrhenius equation,

Homeostatic Imbalances in Body Temperature

Homeostatic Imbalances in Body Temperature

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...

Effects of Temperature on Free Energy

Effects of Temperature on Free Energy

The spontaneity of a process depends upon the temperature of the system. Phase transitions, for example, will proceed spontaneously in one direction or the other depending upon the temperature of the substance in question. Likewise, some chemical reactions can also exhibit temperature-dependent spontaneities. To illustrate this concept, the equation relating free energy change to the enthalpy and entropy changes for the process is considered:

Body Temperature

Body Temperature

The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

Factors Influencing Microbial Growth: Temperature

Factors Influencing Microbial Growth: Temperature

Microorganisms display remarkable adaptations, enabling them to thrive in diverse ecological niches across a wide range of temperatures. Temperature profoundly influences microbial growth by affecting enzymatic activity, membrane fluidity, and other cellular processes.Each microorganism operates within a specific temperature range defined by three cardinal points: minimum, optimum, and maximum. Below the minimum temperature, membranes lose fluidity, halting transport processes. Above the...
