Using Your Phone to Get Fit

Regular physical activity is vital for health, preventing chronic illnesses and improving quality of life. The WHO stresses the importance of accessible and enjoyable exercise. Fitness trackers like Fitbit can motivate users, monitor progress, and enhance health management through personalized coaching. Engaging in physical activity can lead to significant health benefits.

Do you do some type of physical activity regularly, or wish that you did?

You probably know that medical experts recommend physical activity; it not only helps us feel and look better, but it can even prevent certain chronic illnesses and delay death.

“Physical inactivity is a silent threat to global health, contributing significantly to the burden of chronic diseases,” said Dr Rüdiger Krech, Director of Health Promotion at the World Health Organization (WHO.

“We need to find innovative ways to motivate people to be more active, considering factors like age, environment, and cultural background.

By making physical activity accessible, affordable, and enjoyable for all, we can significantly reduce the risk of noncommunicable diseases and create a population that is healthier and more productive.”

Ask yourself these questions :

  1. Has your doctor told you to increase physical activity to treat a chronic condition or to prevent one?
  2. Do you need to lose weight, lower your blood pressure, control your blood glucose(sugar) or cholesterol?
  3. Do you want to feel more fit, stronger, and energetic?
Controlling blood pressure, blood sugar and cholesterol can help prevent and manage heart disease.

 

 

If you answered yes to any of these, and you own a smartphone, consider wearing a smartwatch or tracker like Google Fitbit. I’ve worn a Fitbit watch for several years and find its benefits invaluable. (This is an affiliate link.)
