Lifestyle Medicine

Achieving good health is about more than fixing problems after they appear. Quality of health often begins with the choices we make every day for ourselves, our families, and our communities. Those choices are at the center of lifestyle medicine, an emerging specialty focused on preventing, treating, managing or even reversing many of the most common chronic diseases in today's world.

The World Health Organization estimates that up to 80% of non-communicable conditions such as diabetes, heart disease, cancer, and stroke are preventable when we make better choices in these key areas:

  • Increasing consumption of whole, plant-based foods
  • Increasing aerobic activity
  • Getting enough sleep
  • Decreasing use of tobacco, alcohol, and other unhealthy substances
  • Maintaining healthy relationships
  • Managing stress

The Pillars of Lifestyle Medicine

  • Nutrition

    Food is medicine. Learn how to incorporate more whole foods, fruits, and vegetables into your diet.

  • Physical Activity

    Learn how to make physical activity part of your day-to-day life to improve overall health and well-being.

  • Stress Management

    Stress is inevitable. Learn skills to manage it in healthy and positive ways.

  • Improved Sleep

    Sleep is essential for optimal health. Learn the ins and outs of sleep to get the rest you need.

  • Positive Relationships

    Social connections—friends and family—are key to your wellbeing and directly influence your health.

  • Avoiding Toxic Substances

    Learn strategies to help minimize the impact toxic substances have on your health.
