Psych #1 Test Flashcards
Why is Sleep important for mental health? What Kind of relationship do they have?
Sleep deprivation can affect mental health. People with existing mental disorders are likely to have sleep disorders.
Lack of sleep leads to a lack of REM sleep which is when the brain is restored. This can contribute to mental health disorders.
What are the theories of sleep?
- Repair and Restoration
- Evolutionary Theory
Explain Repair and Restoration.
- During REM sleep the body increases cell division and protein synthesis.
- The body repairs and restores basic body functions and strengthens the immune system from daily activities and possibly sleep deprivation.
Explain Evolutionary Theory
- Sleep to conserve energy during periods of Inactivity
- Over periods species have evolved to enhance survival by sleeping during times when being awake would put them at danger.
- We sleep at night as its dark and we cant see predators and food.
What does the evolutionary theory not explain?
Doesn’t explain why species lose consciousness when asleep if they sleep during times when most at risk.
What Is Sleep Deprivation?
Sleep deprivation increases as sleep debt increases. It is bad for physical and mental health. As there are increased rates of cancer, CVD, infection and brain function decreases.
There are two kinds of sleep deprivation.
Partial sleep deprivation is when most nights of the week you won’t get enough sleep causing sleepiness, desire to nap, and irritable mood.
Continuous sleep deprivation is when you don’t sleep for a while.
Societal Factors of Sleep Deprivation
- Co-sleeping - sharing a bed or room can influence sleep deprivation.
- Social media use - Research has shown that individuals who use social media have more trouble falling to sleep at night.
- Shift work - People who work shift work tend to loose hours of sleep each night or day, this builds up sleep debt.
Personal factors of Sleep deprivation
- Personal Decisions - An individual may make choices that reduce the amount of time available to sleep e.g. watching TV.
- Sleeping disorders - An individual may have a sleeping disorder that reduces the quality and therefore quantity of their sleep.
- Stress - Chronic stress can cause a heightened state of arousal, this can delay onset sleep times.

Due to the parasympathetic nervous system relaxing the body.
Physiological response to stress
- The body when exposed to a stressor activates the automatic nervous system.
- There are two branches.
- Sympathetic Nervous system arouses the body for fight or flight
- The parasympathetic nervous system relaxes the body to freeze response.
Psychological Response to stress

Good effects of fight or flight
- Released adrenaline that helps provide energy by increasing heart rate.
- Cortisol increases glucose in blood bloodstream which provides energy for the brain and nervous system.
