Behavioural therapy is the most effective treatment for depression. Change your state and your thinking and feelings will follow. Most of us can remember the exhilarating feeling of jumping on a trampoline, riding a bike or the fear of crossing a rickety bridge or swinging too high. These fun or fearful feelings are brought on by behaviour. Boosting your optimism and mental health through activities such as mediation, hot sauna, exercise, ice plunge or writing a journal is only the first step in managing your depression. We’ll explore the origins of your depression, why it visits you and how you can deal with it in a way that works for you.
