  2. Interesting Sleep Facts • Horses, cows, and snakes don’t close their eyes when they sleep • An overworked shipmate falling asleep at the wheel caused the oil spill disaster of the Exxon Valdex in 1989. • Some seals and dolphins sleep with one-half of their brain while the other half is alert for danger.

  3. Why Do I Need Sleep? • Lack Of Sleep May Cause… • Increased irritability • Decreased motivation, memory and concentration • Decreased creativity and spontaneity • Increased proneness to injury • Great likelihood of problems such as stomach upset or headaches

  4. What is REM Sleep anyway? • REM stands for Rapid Eye Movement • 25% of each sleep cycle (which is typically 90-minutes) • REM is the stage of most intense dreaming • While in REM your large muscles can’t move, but your pulse, breathing, and temperature go up

  5. Substances that Disrupt Sleep: • Caffeine – don’t have coffee, tea, chocolate or soft drinks with caffeine after mid-afternoon • Alcohol – suppresses REM sleep and may make you wakeful later in the night • Nicotine – people who smoke take longer to fall asleep, wake more often and have less REM and deep non-REM sleep • Diet Pills – often contain ingredients that disrupt sleep

  6. More Interesting Sleep Facts • Humans will die from lack of sleep sooner than from lack of food • The immune system is most active during sleep • All mammals sleep. Grazing animals sleep only 3 hours a day, while bats sleep 20 • Studies suggest Americans may get 2½ to 3 hours less sleep per day than our bodies were designed to have
