When smoking, nicotine quickly enters the blood, causing the brain nervous system to produce a hormone, which can relieve mental symptoms such as tension, depression and irritability. The human body inhales nicotine for a long time, and the brain nervous system relies on nicotine stimulation to produce cigarette addiction. If you quit smoking completely by willpower and your body suddenly loses nicotine, withdrawal syndrome will appear, which is mainly manifested as irritability, anxiety, impatience, palpitation, inattention and serious gastrointestinal discomfort, such as various pains and nausea.
A lot of research evidence shows that quitting smoking can reduce or eliminate the health hazards caused by smoking. People of any age can benefit from quitting smoking. The earlier and longer it lasts, the greater the health benefits. At present, there are effective treatment methods to significantly improve the long-term smoking cessation rate, including short-term advice, drug treatment, smoking cessation consultation, smoking cessation hotline and so on.
