Benefits of stopping smoking

Your health begins to improve sooner than many people realise.

After stopping smoking:

  • 20 minutes Your pulse rate and blood pressure start to return to normal.
  • 48 hours Carbon monoxide and nicotine levels fall. Your sense of taste and smell begin to improve.
  • 2 to 12 weeks Your circulation improves and breathing becomes easier.
  • 1 year Your risk of heart disease is around half that of someone who continues to smoke.

Every smoke-free day benefits your health, and every quit attempt brings you closer to quitting for good.

Protecting others from smoke

Stopping smoking benefits not only your own health, but also the health of the people around you.

Second-hand smoke can increase:

  • asthma and chest infections in children
  • the risk of miscarriage, stillbirth and low birth weight during pregnancy
  • the risk of sudden infant death syndrome (SIDS)
  • health problems in people regularly exposed to tobacco smoke

Creating a smoke-free home and smoke-free car is one of the best ways to protect children, babies and other non-smokers from harmful tobacco smoke.

Smoking and pregnancy

Stopping smoking at any stage of pregnancy can benefit both parent and baby.

Smoking during pregnancy increases the risk of complications including miscarriage, ectopic pregnancy, stillbirth and low birth weight.

If you are pregnant and would like support to stop smoking, specialist help is available at Stop Smoking NI.

Helping children get the best start in life

Children exposed to tobacco smoke are more likely to experience health problems including asthma, chest infections and ear conditions.

Supporting smoke-free environments helps give children a healthier start in life and reduces their exposure to harmful smoke.

The cost of smoking in Northern Ireland

Stopping smoking can improve both your health and your finances.

Someone who smokes 20 cigarettes a day could spend more than £5,000 a year on tobacco.

For many people, quitting smoking means having more money for everyday essentials, family activities and other priorities.

As well as improving your health, becoming smoke-free can bring immediate financial benefits.
