Most of us spend about a third of our lives sleeping. Sleep restores the nervous, muscular, skeletal, hormonal, and immune systems and allows us to consolidate memories. The amount of sleep a child need varies for each individual. It is recommended that children ages 3-6 sleep 10-12hours a night, and children ages 7-10 sleep 10-11 hours a night. Getting more than 7 hours of sleep a night is associated with healthier blood pressure, cholesterol and triglyceride levels in adults. In order to promote healthy sleep habits, establish a regular, relaxing bedtime routine, and maintain this routine on weekends. Monitor your intake of stimulants like caffeine and chocolate. Avoid stimulating activities like exercise and screen time just before bedtime. Create asleep-conducive environment that is dark, quiet, and a comfortable temperature.
