Thermal Stress01:09

Thermal Stress

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...
Thermoregulation01:26

Thermoregulation

The human body has a sophisticated thermoregulation system that employs negative feedback mechanisms to maintain an optimal core temperature. When the core temperature drops, peripheral and central thermoreceptors send signals to the hypothalamus, activating the heat-promoting center. This center triggers several responses aimed at increasing the core temperature. First, vasoconstriction reduces the flow of warm blood from internal organs to the skin so that the heat is not lost from the skin,...
Responses to Heat and Cold Stress02:45

Responses to Heat and Cold Stress

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.
Decreased Body Temperature01:29

Decreased Body Temperature

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 sustained extreme cold exposure, and severe...
Exercise Stress Test01:26

Exercise Stress Test

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
Thermosensation01:43

Thermosensation

Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

Summary

Firefighter gear (TPC) causes physiological strain. Cognitive function, particularly memory recall and reaction time, may be impaired up to two hours after strenuous exercise in TPC.

Area of Science:

  • Physiology
  • Occupational Health
  • Neuroscience

Background:

  • Firefighters face strenuous physical exertion in extreme heat.
  • Thermal protective clothing (TPC) hinders thermoregulation, risking hypohydration and hyperthermia.
  • These conditions can lead to cognitive decline.

Purpose of the Study:

  • To investigate cognitive function changes after treadmill exercise while wearing TPC.
  • To assess immediate and delayed neurocognitive effects of exercise-induced physiological strain in firefighters.

Main Methods:

  • Two studies (Cog 1 and Cog 2) involving healthy volunteers exercising on a treadmill in TPC.
  • Neurocognitive tests measuring memory, attention, and reaction time administered pre- and post-exercise.
  • Physiological parameters like heart rate and body core temperature were monitored.

Main Results:

  • Exercise in TPC induced near-maximal physiological strain (high heart rate, body mass loss, increased core temperature).
  • No immediate cognitive changes were observed post-exercise.
  • Memory recall was reduced at 60 and 120 minutes post-exercise.
  • Reaction times slowed significantly by 120 minutes post-exercise.

Conclusions:

  • Strenuous exercise in TPC causes significant physiological strain.
  • Cognitive impairments, specifically in memory and reaction time, manifest delayed (1-2 hours) after exercise in TPC.
  • These findings highlight potential risks for firefighters' cognitive performance post-exertion.
