However, there are general lifestyle changes that would benefit anyone suffering from depression. Exercise is especially useful. Can he join a gym or take a dog for a long walk each evening? A brisk walk just three times a week would make a difference. He can also make dietary changes - cutting out caffeine and junk foods is a good idea because they keep the body in a stressful state.
