Wellness and psychology expert Lauren Lepley has offered up some top tips for helping you to "rewire" the brain and move through anxious thoughts and mental health challenges. Move your body. This can include anything from going on a walk to working out in your local gym. "Physical exercise releases endorphins, which are natural mood boosters and can help alleviate symptoms of anxiety.” Exercise your mind. Try simple exercises such as positive self-talk or writing down your worries.
