Science Explains What Happens to Your Body from Physical Inactivity

What happens to your body during periods of physical inactivity? We will take a closer look at the decline that happens to the human body when you do not get enough exercise.

What Happens To Your Body If You Don’t Move It?

Remember studying Sir Isaac Newton’s Laws of Motion in high school physics class? Since Newton’s discovery is a physical law, it would also apply to human bodies. Do you keep your body in motion, or does it tend to stay at rest? Here are some serious things that can happen to you when you lack physical activity.

1. Your Metabolism Rate Becomes Sluggish

An article published by the Mayo Clinic states that your metabolism slows down as you get older. Other factors that affect your energy levels include basic body structure, weight, gender, and health. Another major contributor is your physical activity levels.

Think of your metabolism as an interconnected process. For example, when you stay active and exercise, your body can burn more calories. Not only will that help you maintain a healthy weight, but it will keep your body fit and active longer.

Conversely, you’re not going to burn many calories as a couch potato. Your body will eventually adapt to a sedentary lifestyle, and your metabolism is affected. Combine physical inactivity and the consumption of too many calories, and you have a recipe for disaster. You’re at risk for obesity and other severe health conditions.

2. Your Sleep is Affected

Everyone experiences a sleepless night occasionally. According to a study published by the Rand Health Quarterly, at least a third of the people in the U.S. don’t get enough sleep. The ramifications may be more severe than what you think.

An article published by the Sleep Foundation warns that chronic sleep deprivation can affect you physically and mentally. Among the possible consequences the article lists are cardiovascular disease, diabetes, obesity, and mental health disorders. So, sleep isn’t just an optional luxury.

Of course, several risk factors can cause a lack of sleep. Surprisingly, physical inactivity is on the shortlist. While you may feel groggy and sluggish from a sedentary lifestyle, sleep can be a huge issue.

3. You Get Out of Breath Easily

When you are running, lifting, or doing other strenuous activities, it’s normal to get winded. Most people can sit down for a “breather” to rest and restore an average breathing pace. Cardio workouts raise your heart and breathing rate to supply your body with more oxygen to help burn fat.

Physical inactivity can cause your body to have less endurance, including your lungs. For example, you may be gasping and out of breath by simply climbing the stairs at home or work. On the other hand, maybe you’ll notice that you must sit down often to rest and catch your breath if you must do any walking.

Aerobic exercise helps bring more life-sustaining oxygen into your body, plus it gives your lungs a healthy workout. Chronically lounging in front of the television puts your body in a snail mode, so you’re entirely winded with the slightest exertion.

What happens when your lungs aren’t bringing in enough oxygen? You could be at risk for several health issues, and your muscles can be weak. Also, you may notice a decline in memory and cognitive skills because your brain is getting less oxygen.

4. You May Experience Mood Swings and Decreased Mental Health

Have you ever seen a spunky and joyful couch potato? Sure, it may be fun to binge-watch a new tv series over a weekend. It may also be a luxurious splurge to sleep in on occasion. However, constant physical inactivity will eventually affect your moods and mental health.

An article published by Johns-Hopkins Medical states that physical inactivity can lead to mental illnesses such as depression and anxiety. If you have been diagnosed with one or both disorders, consider how much exercise you’re getting daily.

The good news is that being more active may decrease some of your anxiety and depression symptoms. According to an article published by the Journal of Clinical Psychology, exercises such as walking, swimming, cycling, and even gardening can positively affect.

Exercising can also influence endorphins and other chemicals in your brain responsible for well-being. Do you know that “natural high” that you may experience after a brisk walk or other activity? It’s your brain’s way of thanking you for giving your body the workout it needs.

If you are alive, there’s no avoiding stress. Some stress from change is good because it helps you grow and learn. Your body’s instinctual survival mode is dependent on stressors.

Marginal stress is inevitable, but chronic tension and pressure can wreak havoc on your entire being. Humans evolved with a survival response. When triggered, your brain pumps power hormones like adrenaline and cortisone into your bloodstream for a boost of strength.

Unfortunately, your brain doesn’t prioritize stress and will react the same in any situation. Therefore, if you are chronically stressed, the overdose of stress hormones can lead to physical and mental disorders.

An article published by the Anxiety & Depression Association states that regular exercise may reduce your responses to stress. Although physical activities won’t make your life stress-free, they may help you cope with stress in better ways.

Even walking for five minutes a day can positively affect your mood.

6. Your Bones Will Lose Strength

If it weren’t for your skeleton, you would be a puddle of flesh and organs. Your bones provide protection, strength, and stability. Your bone joints work in tandem with muscles and connective tissue to make movement possible.

Have you ever heard the warning “use it or lose it?” Besides eating a healthy diet rich in vitamins and minerals like calcium, your bones also depend on exercise for optimal health. Unfortunately, physical inactivity can make your muscles lax and flabby, and it can also weaken your bones.

Women are most at risk for a decrease in bone density, especially those in post-menopause. As a result, they can often develop brittle bone disease and osteoporosis. However, an article published by the American Journal of Physical Medicine & Rehabilitation says that resistance training may reduce these risks.
