Studies carried out at an American University show that, mindfulness meditation can help improve the symptoms of anxiety and depression. Improvement can be seen if practiced for 30-40 minutes every day. Mediation is also known to have a positive effect on disruptive teenagers, one secondary school in San Francisco America has adopted ‘Quiet Time’ which twice a day a gong sounds and those disruptive teenagers sit still, shut their eyes and clear their minds. A school which was known as one of the roughest schools now has the number of school suspensions fall by 45 % and daily attendance rates have increased to 98%. This is evidence enough of the benefits of still and clearing one’s mind once a day. Credits.
