Document Summary
Relationships: friendships and development of familial relationships. Sleep: allows body to rest and recover, restore energy levels and establishes mental health, allows you to convert short term memories into long term. The body cycles between non-rem and rem sleep. Vivid dreams tend to occur during rem. 50% reduction in activity btw wakefulness, eyes are closed. Waves of muscle contraction and relaxation, heart rate slows and body temperature decreases: stages 3 and 4. During nrem sleep, body repair and regenerates tissues, build bones and muscle, and strengthens immune system. As you get older, you get less nrem sleep. People under 30 have about 2 hours of restorative sleep every night: under 65, 30 min. Increased brain activity: accelerated respiration and increased heart rate, eye movement, muscle relaxation. Typically: rem sleep occurs 90 minutes after sleep onset, 1st period of rem typically lasts 10 minutes, with each recurring rem stage lengthening, and final one lasting an hour, face, fingers, and legs twitch.
