Employees who forego lunch in an attempt
to meet a pressing deadline may finish the task, but their
work just might fall short of company standards.
Low blood sugar (hypoglycemia), which
can occur when otherwise healthy individuals neglect to eat,
can slow the speed at which
people process information and shorten their attention span,
researchers explain. Although low blood sugar can be reversed
with just a few bites of a sandwich, it can affect daily activities
at work and at home.
The results of the study apply to both
healthy individuals who ignore hunger pangs and to diabetics,
who must monitor blood sugar (glucose) and insulin levels
on an ongoing basis. Hypoglycemia occurs when the brain is
temporarily deprived of glucose, its main source of energy.
Many complex attention tasks that are
relevant to everyday life are likely to be impaired during
moderate hypoglycemia.
Individuals
were less able to pay attention during hypoglycemia,
the report indicates, and they also processed visual and auditory
information more slowly.
In the map tests, participants were able
to pick out designated symbols correctly but the speed at
which they located symbols declined. Nonverbal intelligence,
however, was not affected. During hypoglycemia, a significant
deterioration occurs in attentional abilities.
