When stress and anxiety start getting to you, try inhaling four counts and exhaling eight counts. Repeat four to sixteen times. Another method to lower your cortisol and adrenaline (the stress hormones) is to lie on your back or sit in a comfortable position with your eyes closed and slowly relax your toes, your feet, your ankles etc up to your neck, your jaw, the back of your head, the top of your head, your forehead, your eyelids and then your eyes. Stay here as long as you feel comfortable. These exercises stimulate your parasympathetic nervous system which is your rest and digest system.
