Methods of reducing fever01:22

Methods of reducing fever

1.4K
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.

Specific Heat01:16

Specific Heat

67.6K
The specific heat capacity of a substance refers to the energy required to increase the temperature of one gram of that substance by one degree Celcius. Specific heat capacity is often represented in calories (cal), grams (g), and degrees Celsius (oC), but can also be expressed in joules (J), kilograms (kg), and Kelvin (K), among other units.
For example, increasing the temperature of one gram of water by 1°C requires one calorie of heat energy and can be written as 1 cal/g-°C, or...

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 higher temperature. When the...

Heat Flow and Specific Heat01:12

Heat Flow and Specific Heat

6.8K
Heat is a type of energy transfer that is caused by a temperature difference, and it can change the temperature of an object. Since heat is a form of energy, its SI unit is the joule (J). Another common unit of energy often used for heat is the calorie (cal), which is defined as the energy needed to change the temperature of 1 g of water by 1 °C, specifically between 14.5 °C and 15.5 °C, since the energy needed shows a slight temperature dependence. Another commonly used unit is...

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.

Heating and Cooling Curves02:44

Heating and Cooling Curves

28.1K
When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves.
For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...

Area of Science:

  • Physiology
  • Occupational Health
  • Thermal Regulation

Background:

  • Personal protective equipment (PPE) use is essential in many occupations but increases the risk of heat-related illnesses.
  • Glabrous skin regions on the hands, face, and feet are critical for regulating body core temperature through heat exchange.
  • Effective heat dissipation strategies are needed for individuals working in PPE, especially in hot or demanding conditions.

Purpose of the Study:

  • To assess the impact of PPE on heat storage during exercise.
  • To evaluate the effectiveness of palmar (hand) glabrous skin cooling in mitigating heat gain while wearing PPE.
  • To develop and test a wearable cooling system for enhanced thermoregulation.

Main Methods:

  • Subjects performed treadmill exercise in thermoneutral and hot environments, with and without PPE.
  • Palmar cooling was applied using a stationary water circulation system.
  • A novel wearable cooling system was developed and tested for mobility and thermal efficacy.

Main Results:

  • Wearing PPE increased the rate of core temperature rise five-fold during vigorous exercise.
  • Palmar cooling reduced the rate of core temperature rise by 30-60% across various exercise intensities while wearing PPE.
  • The wearable cooling system demonstrated thermal benefits comparable to the tethered system, allowing free movement.

Conclusions:

  • Palmar skin cooling is an effective method to reduce heat storage and core temperature rise in individuals wearing PPE.
  • A wearable cooling system offers a practical solution to counteract the thermoregulatory challenges posed by PPE.
  • This technology has the potential to improve safety and performance for workers in high-heat environments, including healthcare professionals and firefighters.
