Physical activity is an important component of a healthy lifestyle. However, while children once spent much of their free time playing, usually outdoors, modern kids are leading more sedentary lives indoors. Sitting or reclining while using a phone or playing video games means children are spending more time than ever in sedentary behavior, which can lead to long-term negative health effects.  

 According to the Centers for Disease Control and Prevention, only about 24% of children ages 6 to 17 get 60 minutes of physical activity each day. The World Health Organization (WHO) reports that more than 80% of the world’s school-aged adolescents are insufficiently active.

Here’s a look at how this lack of exercise is impacting children.
 

  • According to the WHO, inactivity is directly linked to the global rise in childhood obesity, as sedentary behavior reduces metabolic rates and alters how the body processes fats and sugars. 
  • Without regular physical activity, the lungs and heart are unable to develop the same efficiency as they would if children were physically active. The Journal of the American Heart Association reports that sedentary childhood habits may contribute to arterial stiffness, a precursor to heart disease. 
  • Sedentary children run the risk of entering adulthood with weaker bones and low bone density, potentially leading to orthopedic issues and higher rates of fractures.  
  • Physical activity releases neurotransmitters in the body, such as endorphins and dopamine. Without these natural mood boosters, sedentary children may be at an elevated risk for anxiety and depression. 
  • Reduced physical activity lowers blood flow to the brain and compromises their cognitive health. Children can benefit from physical activity, as it protects against various health conditions that may arise in childhood and later in life.
