As I have said before being outside improves your health greatly. One of the reasons this is true is because outside air is better quality air. The air inside our homes is often recycled and contains dust and everything else that becomes trapped in the air, making the home a bit of a health risk. Another reason being outside is healthy is because the sun supplies us with the best source of Vitamin D. Getting enough of this hormone (not a Vitamin) is essential to maintaining a healthy immune system and those who don't get enough Vitamin D are more likely to suffer from osteoporosis, cancer and Alzheimer's in later life. As always, it's better to get Vitamin D from natural sources-supplementing can be ineffective, expensive and even unsafe. Being outside doesn't just provide children with Vitamin D but is absolutely free and burns any excessenergy
Another reason for children to spend time outside is that it burns any extra energy and feelings of frustration that they might be experiencing at school or home. Children can easily exercise by playing sport or just jogging around the block. Poor diet, misinformation and lack of excercise are leaving many kids overweight. All you have do is thirty minutes of exercise a day which sounds like a lot but goes really fast when your playing basketball in a team with your friends or jogging while listening to music. Exercising also is a good way to stop the "I'm bored" phrase from happening because it gives children something to do that they actually like, playing your favourite sport or just skipping at your own time. Exercising is also a great way to relieve stress.
Tensed and stressed? Head for the trees. One study found that students sent into the forest for two nights had lower levels of cortisol - a hormone often used as an indicator for stress - than those who spent time in the city. In another study, researchers found a decrease in both heart rate and levels of cortisol in subjects in the forest compared to the subject in the city. "Stressful states can be relieved by forest therapy," they concluded. Even among office workers the view of nature outside a window is associated with lower stress and higher job satisfaction. Going outside is also good for concentration.
