The Takeaway

The importance of sleep for children

Nighttime sleep

After the first couple of months—when they sleep round-the-clock!—babies will begin to get the majority of their sleep at night.

Nighttime sleep plays an important role in your child's development and is a vital part of keeping them healthy, both physically and mentally. Here are some of the many ways that sleep affects your child’s health.

Physical health and growth

Getting enough sleep is necessary to ensure that your child has enough energy throughout the day to be physically active, which is essential to their physical health.

Children who aren’t physically active enough due to lack of proper rest are at increased risk of obesity, high blood pressure, and diabetes.

Sleep is also necessary for your child’s physical growth and development. It's when most of their human growth hormone (HGH) level is released into their bloodstream. HGH is vital to your child's growth, but it also helps their body heal and repair itself and regulates their metabolism.
