On-the-Job Hearing Loss Keeping Workers Awake01/27/11
THURSDAY, Jan. 27 (HealthDay News) -- Work-related hearing loss
can lead to sleep problems, a new study has found.
Israeli researchers gave hearing tests to 298 male employees at
a workplace where they were exposed to harmful noise and found that
99 of the workers had a hearing impairment and 199 had normal
hearing. Those with hearing problems tended to be older and to have
been exposed to workplace noise for a longer time.
The condition known as tinnitus, which is a continual ringing in
the ears, was noted in 51 percent of those with hearing loss and 14
percent of those with normal hearing.
Tinnitus was reported as the main sleep-disrupting factor among
the workers. However, insomnia and other sleep problems were also
found among those with other hearing impairments, and neither age
nor years on the job seemed to play a role in that finding, the
researchers from Ben-Gurion University of the Negev, said in a
university news release.
The study, which was carried out by medical student Tsafnat Test
under supervision of Dr. Einat K. Sheiner and others, was published
in the January issue of the journal
"The homogeneous study population exposed to identical harmful noise at the same workplace allowed us to compare sleep quality between similar groups differing only by hearing status," Test explained in the news release.
