Cognitive Dissonance01:38

Cognitive Dissonance

32.5K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Decreased Body Temperature01:29

Decreased 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...

Robbers Cave04:49

Robbers Cave

14.3K
During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

134
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

Respiration is a crucial physiological function involving exchanging oxygen (O2) and carbon dioxide (CO2) between an organism and its environment. Various factors can impact this essential process:

Area of Science:

  • Occupational Health
  • Sleep Medicine
  • Cardiovascular Disease Risk

Background:

  • Firefighter occupation is linked to poor sleep quality and disturbed sleep architecture.
  • Impaired sleep in firefighters can contribute to chronic diseases, including cardiovascular disease (CVD).
  • Understanding sleep patterns is crucial for mitigating occupational health risks.

Purpose of the Study:

  • Quantify firefighter sleep patterns using polysomnography.
  • Compare sleep quality and architecture between sleeping at home and in barracks.
  • Benchmark firefighter sleep data against age-matched normative data.

Main Methods:

  • Ten male firefighters underwent three nights of polysomnography (SleepProfiler™).
  • Sleep recordings were counterbalanced between home and barrack environments.
  • Statistical analysis (rmANOVA with Bonferroni correction) assessed sleep parameter differences (p < 0.05).

Main Results:

  • Statistically significant differences (p < 0.05) were found in cortical arousals, autonomic activations (p < 0.01), and spindle duration (p < 0.01).
  • Sleep in barracks was significantly more disturbed than sleep at home.
  • Firefighter sleep, particularly in barracks, was more deleterious compared to normative data.

Conclusions:

  • Firefighters exhibit poor sleep quality and significantly impacted sleep architecture.
  • Rotating shifts and occupational stress likely contribute to sleep disturbances.
  • Clinical manifestations of disturbed sleep are evident in firefighters compared to the general population.
