Smokers are lazier than non-smokers, lack inspiration and have higher chances of falling into depression and anxiety, a new study says.
According to the study by researchers from Universidade Estadual de Londrina in Brazil, and published in the journal Respirology, smokers walk less each day and feel a lot more fatigued.
Also, they have considerably diminished lung function, which restricts their ability to exercise for long.
During the study about 60 smokers and 50 non-smokers wore a pedometer for a minimum of 12 hours a day for six days, after which they filled out questionnaires rating their fitness-related quality of life.
"To our knowledge, this is the first study that has demonstrated a reduction in the objectively measured level of physical activity in daily life of adult smokers compared with non-smokers," Dr Karina Furlanetto, lead researcher, said in a press release.
The report says that the smokers felt conspicuously tired and admitted to feeling less inspiration to change their lifestyles compared to non-smokers.
"Besides presenting poorer lung function, exercise capacity, quality of life and symptoms of anxiety and depression, smokers also walked less than non-smokers in daily life," Furlanetto said.
In Britain, about ten million adults smoke cigarettes, which amount to a sixth of the total UK population, according to a UK public charity, Action on Smoking and Health (ASH).
Every year, over 100,000 smokers in the country die from smoking-related causes.
Earlier studies have shown that they are more likely to have disturbed sleep and tend to sleep less than non-smokers.
