1.It Helps You Get Exercise
Walking outside makes you more likely to exercise, especially if you’re a kid. You don’t need a gym membership, transportation, or special equipment: Just walk right out your door. You can do many gym exercises at your local park with a simple incline, pull up bar, or set of steps. The push of the wind and the uneven ground can help you vary your workout and burn more calories.
2.It Helps You Get Vitamin D
It’s important for your bones, blood cells, and immune system. It also helps your body absorb more of certain minerals, like calcium and phosphorus. Your body needs sunlight to make it, but you don’t need much. In the summer, just getting sun for 5 to 15 minutes, 2 or 3 times a week, should do it. In the winter, you might need a bit more.
