Be healthy! Aim for a minimum of 30 minutes of moderate intensity activity five times a week – and that doesn’t necessarily mean going to the gym. A brisk walk is just as effective. If you don’t have time for a 30-minute work-out, split it into three 10-minute sessions. Exercise releases endorphins, or ‘happy hormones’, which affect your brain in many positive ways, including helping to decrease muscle tension during sleep.
Exercise also alleviates many of the negative physical effects of stress such as headaches, upset stomach, chest pain and insomnia.
