Sleep-deprivation is a stressor and can trigger the stress
response. High levels of the stress hormone, cortisol, are linked with cravings
for fatty snacks. Columbia University researchers found that those with
insufficient sleep tended to eat an extra 300 calories a day. Both genders ate
more protein-rich foods but only females ate more fat—an average of 31 more
grams of fat after sleeping only four hours.
According
to University of Chicago researchers,
the marked decrease in average sleep duration over the last 50 years coincides
with the increase in prevalence of obesity worldwide—a pandemic.
The
Wisconsin Sleep Cohort Study found that too little sleep altered levels of
appetite-regulating hormones. When tired from lack of sleep, doing
energy-intensive tasks, or dealing with high-maintenance people, many may
further stress their brain by snacking on high fat, high sugar, fast food
items, or beverages with high levels of sugar and caffeine or alcohol.

tomorrow.
