Stereotypes, Prejudice, and Discrimination

Stereotypes, Prejudice, and Discrimination

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who are...

Insufficient Sleep and Sleep Deprivation

Insufficient Sleep and Sleep Deprivation

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...

REM Sleep Behavior Disorder

REM Sleep Behavior Disorder

REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

Sleep-Wake Cycles

Sleep-Wake Cycles

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

Sleep Apnea

Sleep Apnea

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...

Nightmares and Night Terrors

Nightmares and Night Terrors

Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.
Nightmares often...

Area of Science:

Sleep Science
Social Determinants of Health
Psychology

Background:

Racism significantly impacts sleep, with higher discrimination linked to poor sleep in Black adults.
Research on racism's effects on sleep across the adult lifespan is limited.
Racism-related vigilance, the anticipation of racist experiences, is a key factor to explore.

Purpose of the Study:

To investigate the association between racism-related vigilance and sleep duration and quality in Black adults.
To examine if these associations differ between men and women across the adult lifespan.

Main Methods:

Utilized data from a community-based cohort study (Offspring Study of Racial and Ethnic Disparities of Alzheimer's Disease).
Assessed racism-related vigilance using a questionnaire in 258 Black adults (aged 27-89).
Measured sleep duration and quality using a modified Pittsburgh Sleep Quality Index; analyzed associations via linear regression.

Main Results:

Higher levels of racism-related vigilance were significantly associated with poorer sleep quality.
Increased vigilance correlated with lower sleep duration in the overall sample.
These associations between vigilance and sleep were consistent for both women and men.

Conclusions:

Anticipatory experiences of racism, or racism-related vigilance, are linked to diminished sleep quality.
The threat of racist experiences negatively affects sleep quality in Black adults.
Future research and policies should focus on reducing racism-related vigilance to enhance sleep quality.
