Extrinsic and Intrinsic Factors of Health

By Dr. Donald A. Ozello DC

Genetic, extrinsic and intrinsic factors play a major role in our health and fitness. Your genetic make-up is what’s inside your DNA. This is your starting point. Extrinsic factors occur outside the body and intrinsic factors take place in the body.

Each of us has a genetic factor for every disorder, disease and condition. Every person is unique because everyone’s genetic make-up is slightly different. Our fingerprint is a perfect example that no two people are the same.

We can improve our chances of preventing any disorder with our environment. Our environment consists of nutrition, exercise, sleep, rest, relaxation, toxins, the air we breathe, the fluids we drink, how we deal with stress, work station ergonomics and our attitudes. Extrinsic factors are a result of how we live our lives.

Correct strategies to improve how extrinsic factors affect our life increases health, fitness, and functionality and decreases the risk of acquiring disease and activity-limiting symptoms. Our daily decisions contribute to our health. Making healthy decisions lowers your risk of disease while making unhealthy decisions increases the likelihood of disease.

Extrinsic factors can either directly alter our genetics or increase or decrease our genetic risk for all diseases and disorders.

Extrinsic factors affect the intrinsic factors in our bodies. A perfect example is nutrition. Choosing foods which decrease inflammation lowers the risk of heart disease while eating foods that promote inflammation increases the risk of heart disease.

Another easy to understand example is exercise. Aerobic exercise builds endurance and anaerobic exercise build strength thus making the cardiovascular and musclo-skeletal systems function better. Lack of exercise leaves one feeling sluggish and weak because the cardiovascular and musclo-skeletal systems lack power and stamina.

Another classic example of how extrinsic factors affect intrinsic factors in the body is work station ergonomics. If your chair lacks proper lumbar support your back muscles will fatigue quicker. The muscles will tighten and spasm. The muscle spasm produces pain and limits pain-free motion. Proper lumbar support at your work station places the spine in a correct anatomical position and provides support to the muscles, bones and ligaments. This lowers the possibility of acquiring a lumbar sprain/strain from prolonged sitting at your workstation.

Make simple common sense decisions to lessen the damage that extrinsic factors have on your health. Heighten your health, fitness and functionality by increasing the positive affects that extrinsic factors have on your genetics. Enhance your well-being by limiting unhealthy intrinsic factors caused by unhealthy extrinsic factors.
