characteristics of non rem sleep
slow, regular breathing and heart rate, no rapid eye movements, bp and brain activity at 24h low
characteristics of REM sleep
fast & irregular breathing and heart rate, adrenaline spikes, large muscle paralysis, increased brain wave activity, vivd dreams
how many stages of sleep & how long is each stage
5 stages (4 non rem) each lasting about 90 minutes
stage 1 characteristics
5-10 mins, theta brain waves, hypnagogic imagery
stage 2 characteristics
10-30 min, sleep spindles (sudden burst of activity)
stage 3 & 4
15-30 mins, delta brain waves, crucial to feel rested, suppressed by alcohol
