Sleep Quality, not quantity Jet Lag – affects cognitive functioning 1 day to recognize 5 Cycles of Sleep: 1. Transitional stage (1-7 minutes) Sleep onset. Decline in heart rate, muscle tension,, body temperature, Alpha/Theta wave brain activity. 2-4. further decline in heart rate, respiration, muscle tension, body temperature. 3-4. are called slow wave sleep (get there in less than an hour. Remain there for one half hour) low frequency 5. Rapid Eye Movement. Lateral eye movement. Ripple movement across the eyelid Deep Sleep – hard to wake someone up. Irregular breathing, and pulse rate, relaxed muscle tone, Active beta brain wave activity Dreams – Frequent, vivid, memorable. Repeat sleep cycle 4 times REM gets longer 40-60 minutes in length. Non-REM-shorter and shallower Adults=20% Babies=50 Slow wave sleep declines with age. Repair Restoration Theory – we need sleep to recuperate from our daily activities.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
