Smoking in the morning, especially accompanied by a cup of coffee, a ritual that has become hard to break. However, these habits seem to need to be stopped from smoking at the beginning of the day is more dangerous than the smoke of the day or night.
Research shows that smoking after waking may increase the risk of lung cancer, head and neck.
“Smokers have elevated morning levels of nicotine and other tobacco toxins in his body. They are also more dependent than smokers who have quit smoking a half hour or so after waking up,” said researcher Joshua Muscat of Penn State College of Medicine.
To discover why some smokers get cancer or not, Muscat and his team examined the link between cancer risk is there with the habit of first cigarette of the morning.
The first study involved 4775 patients with lung cancer and 2835 of other smokers without lung cancer. Those who smoke 30 minutes after waking up 1.79 times higher risk of suffering from lung cancer than those who waited more than 60 minutes.
Meanwhile, those who smoked 31-60 minutes after waking was 1.31 times the risk compared to those who wait at least an hour.
The second study involved 1055 people with brain and neck and 795 people who smoked but did not suffer the brain and neck cancer. Those who smoked less than 30 minutes when you wake up 1.59 times the risk of cancer to the brain and neck than those who waited an hour.
The risk of smokers who smoked 31-60 minutes after waking up 1.42 times compared to those who wait at least an hour.
The researchers say the findings could help identify smokers who are at high risk of lung cancer, brain and neck as well as benefit from a program aimed at smoking cessation.
However, the risk of cancer remains high even in those who continue to smoke regardless of the time.
