The possible relationship between dietary
cholesterol and cardiac outcomes has been
scrutinized for decades. However, recent reviews of
the literature have suggested that dietary
cholesterol is not a nutrient of concern.
Exposure to traffic pollution is a trigger for
daytime sleepiness, according to new research,
released as part of the Healthy Lungs for Life
campaign.
The new research was presented at the European
Respiratory Society’s International Congress in
London from 3-7 September, which brings together the
brightest minds in lung health to discuss possible
breakthroughs.
Over 12,000 adults were included in the Respiratory
Health in Northern Europe (RHINE) study, which shows
that people exposed to high levels of pollution had
a 65% higher chance of suffering from daytime
sleepiness, compared to those who had no exposure.
Traffic noise in the bedroom was also a trigger –
with people 46% more likely to feel sleepy in the
day if exposed.
What’s more, the research suggests that you are also
29% more likely to be a habitual snorer if you are
exposed to traffic noise while you sleep.
Daytime sleepiness affected 1 in 5 involved in the
study, while one in 4 reported habitual snoring.
Ane Johannessen, epidemiologist from the University
of Bergen in Norway, who has authored the study
together with Icelandic professor Thorarinn Gislason
and other Northern European researchers, said:
“Exposure to traffic should be taken into account
when planning treatment for patients with sleep
disturbances, because reducing noise and pollution
exposure in the bedroom may have a beneficial
effect.
Reducing exposure through relocating the bedroom
away from pollution sources or making the bedroom
more soundproof to protect against traffic noise, as
well as mapping alternative and less polluted
outdoor everyday routes may help patients with their
sleep disorders.”
The study also showed that men, older subjects,
smokers and those with lower education were more
likely to report habitual snoring. Typically they
were less physically active, with a higher BMI, and
more likely to have a diagnosis of OSA (Obstructive
Sleep Apnea).
Women, older subjects, smokers, and those with lower
education were more likely to report daytime
sleepiness.
Commenting on the study, Professor Jørgen Vestbo,
President of ERS and Professor of Respiratory
Medicine at the University of Manchester, said:
“The question of who snores may be a running joke in
some households but for many snoring is a serious
issue, with direct links to physical and mental well
being and the same is true for daytime sleepiness.
We want people to think more about the environment
around them and the impact it can have – from the
way they sleep to the air they breathe”.
