- People exposed to power lines and electrical machinery
at work are at a greater risk of suicide, an American study has shown.
- Power line workers or electricians were up to twice as
likely to die by suicide, possibly because the electromagnetic fields to
which they were exposed made them depressed by reducing the production
of the "mood hormone" melatonin, Dr David Savitz and his colleagues
from the University of North Carolina say.
- They studied the health records of 138,905 male workers
employed by five utility companies between January 1950 and December 1985,
and found 536 suicides. They estimated the exposure of the men to electromagnetic
fields and reported that electricians or linemen appear more likely to
commit suicide, but not those who were plant operators.
