👩 Specific Benefits for Women
Women who quit smoking experience specific health benefits:
- Reproductive Health:
- Fertility improves, making it easier to conceive.
- Quitting reduces the risk of premature births, low birth weight babies, and miscarriage.
- If you’re already pregnant, quitting is the best thing you can do for the health of both you and your baby.
- Contraceptive pill: it is dangerous to both smoke and take the pill. The associated risks (in particular thrombosis) start to decrease as soon as you quit smoking.
- Nicotine affects the nervous system of fetuses and infants because it crosses the placental barrier and passes into breast milk.
- The risk of sudden infant death syndrome is higher when parents smoke.
- Compared to children of non-smokers, children of smokers are twice as likely to become smokers themselves, and they are also more affected by respiratory infections and asthma..
- Hormonal Balance: Your estrogen levels gradually return to normal. Smoking can lead to earlier menopause (1–4 years earlier) and more severe menopausal symptoms; quitting helps mitigate this.
- Cancer Risk: Your risk of cervical cancer drops to near that of a non-smoker within as little as five years.
- Bone Health: Quitting helps protect against osteoporosis and reduces the risk of fractures.
- Wrinkles: Sun exposure and smoking are the two main risk factors for wrinkles. By quitting smoking, you can improve the appearance of your skin.
👴 Specific Benefits for People Aged 65 or Older
It is never too late to quit. Even long-term smokers who quit in their later years gain significant health advantages, often leading to a longer, more active life.
- Longevity: Quitting at age 65 can still significantly add years to your life expectancy and improve quality of life. Even quitting at age 80 reduces the risk of dying from smoking-related diseases.
- Cardiovascular Health: The rapid improvement in circulation and lower risk of heart attack are particularly vital for older adults, whose systems may already be under stress.
- Cognitive Function: Smoking is a risk factor for dementia and Alzheimer’s disease. Quitting can preserve and improve cognitive function, including memory, attention, and processing speed.
- Respiratory Function: Improved lung function is crucial for maintaining an active and independent lifestyle. Quitting helps enhance respiratory capacity and reduces the risk of respiratory infections.
- Medication Efficacy: Smoking can interfere with how some medicines work. Quitting can ensure your medications work more effectively.
