Enough rest: Most children need 10-12 hours of sleep; adolescents require 8-10 hours per night. Sleep is essential for growth, since growth hormone is secreted during slow wave sleep. In addition, reduced and disturbed sleep in older children will suppress Leptin (satiety hormone), increasing hunger which may lead to obesity.

Good nutrition: A balanced diet, rich in necessary vitamins and minerals will enable children to reach their full growth potential.

Regular exercise: Ensure children are physically active. Encourage them to run, cycle, dance and play sports. Exercise strengthens bones, tones muscles, and keeps children active and happy. Set limits for the time they sit in front of the TV, computer and use the smartphone.
