School-age children are going to change a lot physically as they get older. The changes can be subtle and normal, or they may be more obvious and even cause some concern. Here's what you need to know about the physical changes that happen during the teenage years:

Growth spurts

Growth spurts are a normal part of growing up. They can be caused by puberty, but they're more likely to happen during the first few years at school.

Growth spurts are usually associated with puberty, which is when your body starts producing hormones that cause you to grow and develop into an adult. Your body also matures along with your brain; this process happens over several years as well.

Changes in hair and skin

As your child ages, his or her hair will begin to change color. This is actually a good thing! Your child's skin will also become darker and more pigmented as he or she grows older. The changes in both the hair and skin are a sign that your child is getting used to being around other people on a regular basis—and it's important for him or her to develop social skills so that he can make friends at school before starting middle school next year.

As you can see from this list of physical changes of school-age children, there's no denying that puberty happens—and it happens fast!

Changes in sleep patterns

As children get older, their sleep patterns will change. As they approach school age, children may begin to wake up earlier in the morning and go to bed later at night. This is because they are growing and developing physically.

In addition to physical changes like height, weight and body mass index (BMI), puberty can also cause hormonal shifts that affect sleep patterns as well. During puberty girls start producing estrogen which has been shown to make falling asleep more difficult for some young women.[2] Additionally, boys' testosterone levels rise during puberty making it harder for them to fall asleep or stay asleep.[3]
