Mental Health and Wellness

92 flashcards by MentisLibrary

Stress physiology, sleep architecture, mindfulness, burnout, and the coping concepts that research actually supports. Educational literacy for understanding your own mind, not a substitute for professional care.

Is this deck a substitute for professional mental health care?
No. This deck is educational reference material only. Anyone with a personal concern should contact a qualified professional or a local crisis line.
What is the HPA axis?
The hypothalamic pituitary adrenal axis, the hormonal pathway that governs the body's slower stress response.
What is cortisol?
A glucocorticoid hormone released by the adrenal cortex that raises available blood glucose and shifts the body toward mobilizing energy.
Which hormone drives the fast, immediate stress response?
Adrenaline, also called epinephrine, released by the adrenal medulla within seconds.
What does the fight or flight response describe?
The rapid physiological mobilization for confronting or escaping a perceived threat.
What does the sympathetic nervous system do?
It is the branch of the autonomic nervous system that mobilizes the body for exertion or threat.
What does the parasympathetic nervous system do?
It is the autonomic branch associated with rest, digestion, and recovery after arousal.
What is the difference between acute and chronic stress?
Acute stress is a short lived response to a specific demand that resolves; chronic stress is prolonged activation that does not fully switch off.
What is allostatic load?
The cumulative wear on the body from repeated or prolonged activation of stress response systems.
What does the Yerkes-Dodson relationship describe?
An inverted U shape between arousal and performance: performance improves as arousal rises, then declines once arousal gets too high.
What is a stressor?
Any demand, event, or condition that triggers a stress response.
What is cognitive appraisal in stress theory?
The process by which a person evaluates whether a situation is threatening and whether they have the resources to handle it.
What is heart rate variability?
The variation in time between consecutive heartbeats.
What are the main stages of human sleep?
Three NREM stages (N1, N2, N3) plus REM sleep.
What characterizes REM sleep?
Rapid eye movements, brain activity resembling wakefulness, vivid dreaming, and near paralysis of most skeletal muscles.
What is slow wave sleep?
The deepest NREM stage, N3, marked by high amplitude, low frequency delta waves.
What is the circadian rhythm?
The roughly 24 hour internal cycle that regulates sleep, alertness, hormone release, and body temperature.
What is a zeitgeber?
An external cue that synchronizes the internal body clock to the outside world.
What is sleep pressure?
The steadily building drive for sleep that accumulates the longer a person stays awake.
What role does adenosine play in sleepiness?
Adenosine accumulates in the brain during waking hours and promotes the feeling of sleepiness; sleep clears it.
What is melatonin?
A hormone released by the pineal gland as ambient light falls, signaling biological night.
What does the term sleep hygiene refer to?
The set of behavioral and environmental habits associated with better sleep, such as a consistent schedule, a dark cool room, and limiting late caffeine.
What is sleep debt?
The accumulated shortfall between the sleep a person needs and the sleep they actually get.
What is a chronotype?
An individual's natural tendency toward earlier or later timing of sleep and peak alertness.
What is social jetlag?
The mismatch between a person's biological sleep timing and the schedule their work or school demands.
Why is morning light exposure emphasized in sleep research?
Bright light early in the day helps anchor the circadian clock and tends to advance sleep timing earlier.
What is sleep inertia?
The temporary grogginess and reduced performance right after waking.
How is mindfulness usually defined?
Paying attention on purpose, in the present moment, without judgment.
What is MBSR?
Mindfulness Based Stress Reduction, a structured eight week group program combining meditation, body awareness, and gentle movement.
What is MBCT?
Mindfulness Based Cognitive Therapy, which combines mindfulness practice with cognitive therapy elements.
