Running not only keeps you in shape, but it also helps you live longer. And while it all looks great, it’s only a small part of what sport can do for you. It literally influences your body, from head to toe. Even your trips to the bathroom can be affected.

We like to go for a good run. However, we never think about the body changes that can occur during exercise. Let’s find out more on this topic together.

Your Toenails May Turn Black


With every step you take on the ground while running, your toes hit the front of the shoe. Small shoes and tight socks may squeeze the toenails. The same happens if your legs swell.

And all this can lead to a bruise under the nail. The vessels break, blood pools outside of them, and the nail changes color.

You Can Become Shorter


When you run, the height and volume of your spinal discs decrease. This happens due to loss of fluid and compression, and you can lose almost 0.5 inches. Fortunately, this will only be temporary, as your height will be restored.

Your Hearing May Sharpen

Running increases blood flow to the cochlea while increasing the flow of nutrients and oxygen in the body. Helps reduce wear and tear on the auditory system and preserves capillaries, hair, and nerve cells that send audible signals to the brain.

You Might Get A Runny Nose

As you run, you breathe faster and deeper and inhale more air. By doing so, you inhale more allergens, pollution, and irritants from the environment. This irritates the airways and makes your nose runny.

Your Temperature Can Rise

Muscles obtain energy by burning fat and carbohydrates. As a result, heat is generated. Along with the muscles, the blood is also heated, increasing the temperature.

After that, blood flow to the skin increases and sweat cools it down.

You May Have The Urge To Poop

Running can release hormones in the stomach that increase contractions in the intestines. The contents of the stomach tremble and can disrupt the mucous membrane of the gastrointestinal tract.

Also, blood flow to the intestines decreases, causing cramps and defecation.
