Have you ever climbed a tree? When was the last time you took a walk in a park? When you're busy with schoolwork, you may have no time to spend outdoors. However, it can actually be bad for your mental health. The World Health Organization reported that more than 450 million people around the world have some kind of mental disorder(精神疾病).
According to researchers from Aarhus University in Denmark, children who spend more time outside are less likely to have mental disorders later in life. They mapped the amount of "green space"" around the homes of 1 million Danes(丹麦人) who were born between 1985 and 2003.They compared this data with the risk of developing different mental disorders later in life. They found that people who grow up in "green" areas are 55 percent less likely to develop mental disorders in adulthood.
Having more green space in a particular area means there are probably fewer roads and less pollution. This gives more chances for people to exercise and interact with each other. Simply being in a green area outside can help people relax and release pressure. All of these factors can have an impact on mental health, lead scientist Kristine Engelmann told Science Daily.
