Tired muscles
Muscle deterioration. When you smoke, less blood and oxygen flow to your muscles, making it harder to build muscle. The lack of oxygen also makes muscles tire more easily. Smokers have more muscle aches and pains than non-smokers.
More Broken Bones
Ingredients in cigarette smoke disrupt the natural cycle of bone health. Your body is less able to form healthy new bone tissue, and it breaks down existing bone tissue more rapidly. Over time, smoking leads to a thinning of bone tissue and loss of bone density. This causes bones to become weak and brittle. Compared to non-smokers, smokers have a higher risk of bone fractures, and their broken bones take longer to heal.
