The Dangers of Sleep Deprivation

THE DANGERS of
SLEEP
DEPRIVATION

By A Page

Just one week of insufficient sleep
alters the activity of our genes,
which control our response to
stress, immunity, inflammation
and overall health. Here are the
hidden health hazards caused
by sleep deprivation.

HIGHER LEVELS
OF ANXIETY

PANIC


Lack of sleep amplifies the brain’s
anticipatory reactions, raising
overall anxiety levels.

HIGHER LEVELS
OF DEPRESSION

decrease in neurotransmitters
which regulate mood.

health, which weakens our

HEART DISEASE
When we sleep our blood pressure
drops. Not experiencing this nightly
drop in pressure is a risk factor
for heart disease.

BREAST CANCER

Late night exposure to light

production, which disrupts estrogen
production. Too much estrogen
promotes the growth of breast cancer.

HIGHER RISK
OF DIABETES

Lack of sleep triggers our stress
response, leading to the release of the
stress hormones cortisol and
norepenephrine, which are associated
with insulin resistance.
