Complete the chart to show the difference between what happens to the body during most stages of sleep AND REM sleep

• Heart rate and blood pressure rise during REM sleep, Sympathetic nervous system jumps to twice the state that is normal during the day

• Heart rate and blood pressure remain constant during most stages of sleep, Sympathetic nervous system is inactive

• Heart rate and blood pressure decrease during most stages of sleep, Sympathetic nervous system is more active

• Heart rate and blood pressure increase during most stages of sleep, Sympathetic nervous system is less active

What are the possible effects of stress hormones?

• We perspire, It expands the air passages in our lungs
