Health Informatics?

Whenever I tell people about the Masters of Health Informatics program at the University of Victoria, they always ask what Health Informatics is.  I guess to a certain extent, the term Health Informatics is still fairly new.  Here is a brief introduction of what Health Informatics really is.

Health Informtics is the intersection of information science, computer science, and health care.  It deals with the resources, devices, and methods required to optimize the acquisition, storage, retrieval, and use of information in health and biomedicine.  Health informatics tools include not only computers but also clinical guidelines, formal medical terminologies, and information and communication systems.  Sometimes,  Health Informatics is referred to as Medical Informatics.

Health Informaticians are expected to have knowledge in:

  • architectures of Electronic Health Records and other health information systems used for billing, scheduling, and research;
  • decision support systems in healthcare;
  • standards and integration profiles to facilitate the exchange of information between healthcare information systems;
  • controlled medical vocabularies;

If you want to know more about Health Informatics, Wikipedia has an in-depth explanation on its development, location, legal aspects, and management.

Difference between Aerobic and Anaerobic exercises

Aerobic exercises are those that help to reduce fat, these include walking, running, swimming, cycling, hiking, etc.  This type of exercise increases the heart rate and breathing becomes heavier.  After about 20 minutes of aerobic exercise, the body begins to use its stored fat as fuel, hence the phrase “burning fat”.  Regular aerobic exercise raises your body’s metabolism and enables your body to use more calories, even when you are at rest.

Anaerobic exercises help you to develop stronger muscles.  These exercises involve short bursts of force followed by periods of rest.  Anaerobic exercise does not burn fat like aerobic exercise, but helps to build muscle.  An increase in muscle mass complements aerobic exercise by enabling you to use more calories.

The benefits of exercising

I’m sure we all know exercising is good for us, but do we really know how good it is for us?  Let me break it down for ya.

  • Aids in the prevention of disease – Physical inactivity can lead to a number of degenerative diseases such as diabetes; regular exercise can help delay and even prevent the onset of chronic illnesses.
  • Helps treat injury – Exercise is used to treat physical limitations through exercise, stretching and conditioning.
  • Promotes restful sleep – Those who participate in regular exercise tend to be more relaxed and burdened with less stress.
  • Promotes optimal body composition – When participating in regular physical activity you use up more calories; therefore decreasing the likeliness of gaining unhealthy weight.
  • Optimal bone density – Resistance exercise helps to build and strengthen bones thus reducing  your risk of developing osteoporosis.
  • Strengthens circulation and lung function – Aerobic exercise helps to strengthen the heart and lungs and helps to lower your risk of cardiovascular disease.
  • Promotes self-confidence and decreases depression – Setting and achieving your goals help increase self image and can promote positive well-being.

That’s what I can think of so far.  I’m sure you know more than the above benefits.  I would love to hear your ideas.  Please post your ideas under this topic by leaving your comments.  Thank you 🙂
