Responses to Heat and Cold Stress02:45

Responses to Heat and Cold Stress

13.6K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

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.

Increased Body Temperature01:25

Increased Body Temperature

718
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...

Requirements for Human Life

8.3K
The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

Homeostatic Imbalances in Body Temperature

159
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...

Thermal Stress01:09

Thermal Stress

2.5K
If the temperature of an object is changed while it is prevented from expanding or contracting, the object is subjected to stress. The stress is compressive if the object expands in the absence of constraint and tensile if it contracts. This stress resulting from temperature change is known as thermal stress. It can be quite large and can cause damage. To avoid this stress, engineers may design components so they can expand and contract freely. For instance, on highways, gaps are deliberately...

Summary

Extreme heat disproportionately impacts vulnerable older adults. Targeted interventions are crucial, as heat vulnerability varies significantly between geographic areas and individuals, especially those in rental housing.

Area of Science:

  • Environmental health equity
  • Climate change adaptation
  • Gerontology and public health

Background:

  • Extreme heat poses a significant environmental health equity challenge, disproportionately affecting low-income older adults and communities of color.
  • Factors like rental housing, lack of air conditioning, chronic disease, and social isolation amplify mortality risks for older populations.
  • Adaptive heat mitigation faces barriers, particularly in historically temperate regions.

Purpose of the Study:

  • To measure two heat vulnerability indices to identify high-risk areas and individuals.
  • To analyze spatial variations in heat vulnerability at both area and individual scales.
  • To discuss targeted mitigation strategies for older adults vulnerable to extreme heat.

Main Methods:

  • Construction of two heat vulnerability indices for the Portland, OR metropolitan area.
  • Area-scale index using existing regional proxy measures.
  • Individual-scale index using post-heat dome event survey data, analyzed with principal component analysis and GIS.

Main Results:

  • Significant spatial divergence between area- and individual-level heat vulnerability.
  • Identification of a specific area with a high concentration of age- and income-restricted rental housing as highly vulnerable on both indices.
  • Demonstration of differing risk distributions across scales.

Conclusions:

  • Heat risk management policies should be spatially tailored, not uniform, due to variations in vulnerability.
  • Targeting resources to specific vulnerable older adults and areas enhances efficiency and cost-effectiveness.
  • Prioritizing assistance in high-risk zones, like those with concentrated rental housing, is essential for effective heat risk reduction.
