Teenage stress

Now teenagers have stress, some of the reasons are:

Her parents have arguments very often because of their problems.Teenagers have to move to a new school, make new friends and  adapt themselves to new things. Sometimes they don't  have enough privacy.
The activities that theyhave to do also affect teenagers. They have  to train many hours a day, to study for exams, and after all these activities the teenagers don't sleep  enough hours; they should sleep eight hours, but they prefer to go to bed late and sleep more in the morning.
Therefore they should improve their habits.
