One very effective step that an individual can take to enhance their health and well-being is to quit smoking. But one question that most smokers want to get clarified is what happens to their body the moment they stop smoking and how soon they will record a serious change in terms of health.
Being aware of the quitting cigarettes timeline and its health-related milestones can encourage you to quit cigarettes and get ready to experience beneficial changes on the way.
This article provides a detailed health timeline of all of the benefits you will see as you stop smoking, from the very first hour after your final cigarette to years further along. And find out how new technologies such as the QuitSure app can help you quit without fail, the smart way, using science and psychology.
The Importance of Quitting Smoking
The World Health Organization (WHO) says that cigarette smoking causes over 8 million deaths annually across the globe. Smoking harms almost all organs of the body and causes most preventable illnesses like lung cancer, heart disease, stroke, and chronic obstructive pulmonary disease (COPD).
However, there are huge dangers that can still be minimized by giving up smoking, despite having years of smoking experiences. The sooner you stop smoking, the higher the odds of avoiding critical health issues. Yet, a number of smokers are afraid or never succeed because nicotine is not only a chemical addiction but also a mental one.
Why You Cannot Quit Mental Addiction
Mental addiction is subconscious associations you formed with smoking for stress relief, social triggers, or habits like a cigarette with coffee or after meals. These generate intense triggers as well as cravings, which chemical solutions cannot overcome.
That is why the majority can stop smoking with the help of nicotine patches or medication. Long-term success requires rewiring the brain's reward system and learned behaviors.
