St George's: People who smoke shisha regularly could be increasing the threat of heart disease, according to new research. Shisha smoking, which is also called hookah or hubble-bubble smoking, is a way of smoking tobacco which is sometimes mixed with flavouring, through a bowl using a hose or tube which has become fashionable in Middle Eastern-style cafes. New research from University of London, shows that heart rate, blood pressure and carbon monoxide levels rise significantly immediately after smoking shisha. These physiological changes may lead to heart disease which in turn can lead to heart attacks.
The study was carried out in 2012 in six London shisha cafés where
participants smoked for a period between 45 and 90 minutes.The same
brand of tobacco and coal was used.
Those who had had smoked shisha in the previous 24 hours, who
normally smoked cigarettes or who suffered from cardiorespiratory
problems, were excluded from the study.
Professor Madden said: “Young people may be attracted to the social
ambiance of these smoking cafes but they should also be aware that
shisha smoking may well have an adverse effect on their health.
“There is minimum public awareness of the health risks of shisha smoking and a lack of scientific data.
“This research shows that there is an elevation in heart rate and
mean blood pressure and carbon monoxide levels after smoking shisha and
this may important in the development of cardio vascular disease.
“Further research is needed to verify the results of this research and to investigate the wider effects of smoking shisha.
“If future studies note the same effects of this research then the
public should be made aware of the health effects of shisha smoking.
This would include mandatory labelling of shisha tobacco packs and
apparatus with ‘smoking kills’, which to date is not enforced at shisha
Researchers found that mean average arterial blood pressure increased
from 96 mmHg to 108 mmHg, as did heart rate increased from 77 to 91 bpm
and carbon monoxide also increased from an average of 3 to 35 parts per
The weak correlation between carbon monoxide levels and the other
variables suggests that carbon monoxide levels had not contributed to
their significant increase.
