6. Your DNA
While it is easy to understand that smoking can physically damage your body and lungs, it may be surprising to know that your very DNA is affected. Constant exposure to smoke causes your cells to mutate at the cellular level. These cellular mutations can develop into cancer. It can take years to undo the effects smoking has on your DNA. There’s no better time than the present to give up smoking and be on your way to healthier DNA.
5. Your Hormones
Give up smoking and your hormones will get back into balance. In women, smoking can cause infertility, irregular menstrual cycles, and early menopause. In both men and women, smoking affects the pituitary, thyroid, and adrenal glands. Stopping smoking allows your hormone levels to return to normal.
4. Your Stomach
Stop smoking and your stomach will thank you. Heartburn will decrease as the sphincter in your esophagus becomes strengthened and keeps stomach acids from backing up. Smoking may be linked to an increased risk of Helicobacter pylori infection, the bacteria that causes peptic ulcers. Smoking cessation decreases this risk and allows your gastrointestinal tract to return to normal.
