We all know that eating healthy, exercising, and getting enough sleep is good for our health, and that smoking and drinking too much is not, but there are various other bad habits hurting our bodies that doctors suggest we stop doing immediately.

From sitting down for too long to carrying a heavy bag on one shoulder, there are many things that we do each day that can hurt our health.

Doctors recommend we break these 5 bad habits that are harming our bodies:

1. Wearing shoes that hurt your feet. That pain you feel when you wear high heels, or shoes that don't fit properly, is your body saying you could be harming it. Jeannette South-Paul, MD, told Reader’s Digest that footwear was linked to the health of your feet, knees, hips and back. High heels cause Achilles tendon tightness and put pressure on the calves while studies found that flip-flops can cause problems from your feet all the way up to your lower back because they change the way you walk.
2. Not practicing good oral care. If you are guilty of skimping on brushing your teeth and are lazy about flossing the chances are you could be harming your body without realizing it. Grant Fowler, MD told Reader's Digest that these bad habits are the biggest risk for dental decay.  "Poor dentition is a risk factor for many things including major, overwhelming infections and malnutrition — especially in the elderly — and also cardiovascular disease," he said. Dr. Ann Bolger, a cardiologist and professor of medicine emeritus at the University of California, San Francisco, noted that gum disease puts the body in a continual state of inflammation, which could be a very powerful predictor of cardiovascular disease, according to the American Heart Association.
3. Poor bathroom habits.  Not answering the call of nature is another bad health habit that doctors really want us to break. "Urine is like a creek or river. If you block it, the stream becomes stagnant and gives bacteria the chance to grow in the bladder, and maybe to move back upstream to your kidneys," Fowler told the Reader's Digest.
4. Biting your nails. It may be a nervous tic but nail biting is a bad habit that can hurt your body in several ways. Firstly, it can damage the nails and cause infection to the skin surrounding it, Asif Ansari, MD, told Reader's Digest. You can also introduce viruses into your body that can lead to infection and illness. It is also bad for your teeth. According to news from the Texas A&M University Health Science Center, biting your nails can actually cause your teeth to shift out of place.
5. Chewing gum. Constantly chewing gum could be putting too much pressure on your jaw and can lead to arthritis, clicking, and pain, South-Paul told to the Reader's Digest. "The temporomandibular joint — at the top of the jaw — is a synovial joint just as seen in the knees," she explained. It is even worse if the gum you are chewing is sweetened with sugar, which is bad for the teeth and can cause tooth decay, Healthline noted.
