Everyone wants to feel healthy and have energy! I created this page so that I can share ideas and information about how diet, exercise, sleep and stress impact your health. I have a PhD in Physiology and I am a Registered Holistic Nutritionist. I am a professor and textbook author and I love teaching and writing about anything that affects our health.  All of my posts reference published peer-reviewed research studies and the links are available at the end of each post.  I welcome all comments and questions.
