What is sleep pressure and how does it change over 48 hours? |
Sleep pressure is the tendency to asleep that increases throughout the day. It is lowest when you first wake up in the morning and highest at night. |
|
|
What happens to sleep pressure when you skip a night of sleep? |
Sleep pressure fluctuates between normal ranges every day; when you skip a night of sleep, sleep pressure will accumulate and go over that homeostatic range. This results in sleep debt. |
|
|
What would happen to sleep pressure if you took a nap during the day? |
Sleep pressure would decrease. |
|
|
Describe three examples of how sleep pressure can interfere with human performance. |
Driving, medical errors, pilots - lack of motor skills and concentration lead to increased human errors as sleep pressure builds |
|
|
How much sleep is recommended for children (6-13), teens (14-17) and adults(18-64)? |
Children: 10-11 hours Teens: 8.5-9.5 hours Adults: 7-9 hours |
|
|
How would you calculate your sleep deficit over one week? |
(Amount of sleep we need - amount of sleep we get) |
|
|
What are limitations to calculating sleep deficit based on the equation provided in class? |
It doesn't take into account sleep efficiency, and likewise it is hard to recall how much sleep you actually get per night. |
|
|
Define sleep latency and describe why it interferes with sleep quality. Provide an example of changes in sleep latency. |
Sleep latency: time it takes to fall asleep; if it takes longer to fall asleep, you will be sleeping for fewer hours throughout the night Napping during the day might make it harder to sleep at night; increased sleep latency |
|
|
Define mid-sleep disturbances and describe why they interfere with sleep quality. Provide an example of changes in mid sleep disturbances. |
Mid sleep disturbances refer to waking up in the middle of the night after falling asleep. |
|
|
Define sleep fragmentation. Provide an example of fragmented sleep. |
Sleep fragmentation refers to waking up in the middle of the night multiple times rather than falling asleep throughout the entire night. |
|
|
How do you calculate sleep efficiency? Is sleep efficiency good or bad? |
Sleep time/ time in bed; having higher sleep efficiency is better for sleep quality |
|
|
Why do individuals with sleep apnea feel sleepy during the day? |
Their sleep is very fragmented. |
|
|
How does sleep pressure differ for an individual who is rested versus drowsy? |
Sleep pressure is much lower for an individual who is well rested, where as the sleep pressure is much higher for the drowsy individual. |
|
|
Describe the details of the study that demonstrated the correlation between poor sleep quality and academic performance? Who did they test? What did they measure?What were the conditions? What did they find? What does it mean? What were the limitations of the study? |
414 university students, about half of them have a full course load Measured sleep quality through the Pittsburgh Sleep Quality Index (a survey) and academic performance in an intro pysch. course and overall GPA Found that there was an association between sleep quality and academic performance (both mark in the psych. course and overall GPA) for students taking a full course load Limitations: self-reported sleep measure, didn't consider intellectual differences, correlation not causation |
|
|
What factors do we need to account for when calculating the costs associated with sleep deprivation? |
Lost productivity and human error, health care costs, and human life. |
