Sleep and sleep cycles were presented by an assistant professor. Rapid eye movement (REM) sleep and sleep spindles, which are neural activity marking the transition from waking to sleep, were discussed. Circadian rhythms, the 24-hour cycle including sleep, are regulated by the circadian clock which responds to light and dark and helps control functions like sleep schedule, appetite, temperature, hormones, alertness, performance, blood pressure, and reaction times.

physiological and behavioral rhythms like sleeping
• The circadian clock plays a physical, mental, and
behavioral role that responds to light and dark.
This clock helps regulate functions that include:
• sleep schedule
• appetite
• body temperature
• hormone levels
• alertness
• daily performance
• blood pressure
• reaction times
