Sedentary lifestyle effects/What happens to your body when you are less active?

While you may be enjoying that sitting or desk job, driving back home and watching your favorite Tv show every day, it is killing you softly. A sedentary lifestyle has a lot of side effects on the body and general health.

  • A sedentary lifestyle may also weaken your immune system leaving your body prone to diseases and attacks. 
  • Hormonal imbalances are also very common in people who are less physically active. 

what are the health risks associated with an inactive lifestyle?

According to Wikipedia, ”At least 300,000 premature deaths, and $90 billion in direct healthcare costs are caused by obesity and sedentary lifestyle per year in the US alone.” The risk of diseases and premature death is higher in people who sit more than 5 hours per day. 


Obesity is a medical condition where the body gains excessive amounts of body fat causing a negative effect on health. 

The body makes fat when you consume more calories than you burn.  A sedentary lifestyle makes you less active, burn fewer calories and increase chances of being obese. 

Since a lot of calories are burned t through physical activities, when you are less active, the number of calories burned is usually minimal. 

You will not become obese overnight but your body will keep accumulating or gaining fat to the extent of overweight and finally obesity if no action is done towards calorie restriction and exercises.

Type 2 diabetes.

Diabetes is a condition or disease that occurs when blood glucose or blood sugar is too high.  

A sedentary lifestyle can lead to overweight or obesity which eventually increases the risk of pre-diabetes and type 2 diabetes. From statistics, over 90% of diabetics are overweight. 

Being less active increases insulin resistance and other conditions such as high blood pressure which all contribute to type diabetes development. 

Increased risk of certain cancers.

According to a study published in NCI: Journal of the National Cancer Institute to assess the relationship between Screen time, recreational sitting time, and occupational sitting with the risk of various cancers. 

From a meta-analysis carried out by Daniela Schmid, Ph.D. and Dr. Michael Leitzman of the Department of Epidemiology and Preventive Medicine, University of Regensburg, Germany, it was found out that people with a high sedentary level had a significantly high risk of three types of cancers compared to people with lower sedentary behaviors. 

Cancers such as colon cancer, endometrial, and lung cancer were highly associated with people who are less active.  

Watching Tv showed the strongest relationship to these cancers since it usually involves drinking sweetened drinks and eating junk foods. 

From the researchers, ‘’ sedentariness has a detrimental impact on cancer even among physically active persons implies that limiting the time spent sedentary may play an important role in preventing cancer…”. 

Increased cardiovascular disease.

A sedentary lifestyle increases the risk of cardiovascular diseases since it is linked to diabetes, weight gain, high blood pressure, and hypertension which are great contributors to the development of cardiovascular diseases. 

It is estimated that approximately 35% of coronary heart disease in the USA is due to a sedentary lifestyle from statistics by the New York State. 

People who live a sedentary lifestyle are more likely to experience heart diseases such as coronary artery disease and heart attack.  

According to an old study by NCBI. ”In men, riding in a car and combined time spent in these two sedentary behaviors were significant CVD mortality predictors. Additionally, high levels of physical activity were related to notably lower rates of CVD death even in the presence of high levels of sedentary behavior. Health promotion efforts targeting physically inactive men should emphasize both reducing sedentary activity and increasing regular physical activity for optimal cardiovascular health.” 

 Pre-mature death.

It’s not to scare you but being a couch potato reduces your life span. Since it is also associated with diseases such as obesity, heart disease diabetes, and certain cancers, you are more likely to die if you do nothing on such a type of living. 

A more physically active person is likely to be much healthier than a sedentary person. When you involve yourself in challenging activities such as workouts, your body becomes a lot much healthy since physical activities can burn fat, clear veins, sweat out toxins, and many different body activities that contribute to healthy living. 

According to Science Daily, ”Two decades of a sedentary lifestyle is associated with a two times risk of premature death compared to being physically active, according to recent study results.”
