How
does a lack of sleep contribute to inflammation? The body's natural response to
disease and injury is inflammation.
When
you get a cold or cut yourself, your immune system activates white blood cells,
which release cytokines and other inflammatory molecules that attack invaders
and protect the body's tissues.
When
this reaction is only temporary, it is an effective defense mechanism. However,
chronic inflammation can contribute to the development of heart disease,
diabetes, stroke, cancer, and Alzheimer's disease.
Sleep
deprivation is linked to inflammation markers such as increases in inflammatory
molecules such as cytokines, interleukin-6, C-reactive protein (an inflammation
marker that is elevated in people at risk for heart disease and diabetes), and
others in people who aren't sleeping well.
While
these inflammatory signs could be attributed to other factors, such as stress,
smoking, or obesity, they do suggest that sleep deprivation plays a role in the
inflammatory process.

They
may also help to explain why people who sleep poorly are more likely to develop
heart disease, high blood pressure, and diabetes, among other chronic
conditions.
How
does a lack of sleep contribute to inflammation? One theory is centered on
blood vessels. Blood pressure drops and blood vessels relax while sleeping.
When
sleep is limited, blood pressure does not fall as it should, which may activate
cells in blood vessel walls that cause inflammation.
Sleep
deprivation may also alter the body's stress response system.
Furthermore,
a lack of sleep disrupts the normal operation of the brain's housecleaning
system, known as the glymphatic system (not to be confused with the lymphatic
system in the rest of the body).
Cerebrospinal
fluid rushes through the brain during deep sleep, sweeping away beta-amyloid
protein, which has been linked to brain cell damage.

This
housecleaning process is less thorough without a good night's sleep, allowing
the protein to accumulate and inflammation to develop.
Then
a vicious circle begins. Beta-amyloid buildup in the frontal lobe of the brain
begins to impair deeper, non-REM slow-wave sleep.
This
damage makes it difficult to sleep as well as retain and consolidate memories.
Even
one night of sleep deprivation can keep beta-amyloid levels elevated. The issue
is not so much a single night of poor sleep, which can be compensated for, as
it is a cumulative pattern of sleep loss, which leads to decreases in the
structural integrity, size, and function of brain regions like the thalamus and
hippocampal, which are especially vulnerable to damage during the early stages
of Alzheimer's disease.
FAQs Related To How Does A Lack Of Sleep
Contribute To Inflammation
Can sleep reduce inflammation?
If
you sleep better, your inflammation will decrease, and you will experience
relief from this chronic swelling. To help your body develop a consistent
sleeping pattern, go to bed and wake up at the same time each night.

How does the lack of sleep affect your immune
system?
Sleep
deprivation has been linked to a decrease in the production of these protective
cytokines. Furthermore, when you don't get enough sleep, your
infection-fighting antibodies and cells are reduced. As a result, your body
requires sleep in order to fight infectious diseases.
Why does inflammation increase during sleep?
The
immune system releases cytokines during sleep, which are protective proteins
that serve a variety of functions, including facilitating the body's
inflammatory response to illness and injury.
What is the main cause of inflammation in the
body?
The
following are the most common causes of chronic inflammation: Lupus is an
example of an autoimmune disorder in which your body attacks healthy tissue.
Toxin exposure, such as pollution or industrial chemicals. Untreated acute
inflammation, such as that caused by an infection or an injury.

What reduces inflammation fast?
Reduce
your intake of sugar and processed foods to reduce inflammation quickly. But,
perhaps more importantly, engage in stress-reduction activities, get a good
night's sleep, and eat a colorful, anti-inflammatory diet.
What slows down inflammation in the body?
Ice.
Apply an ice pack to the injured and painful area right away. Ice
"pulls" heat away from an injured body part, lowering tissue
temperature and slowing or stopping the "chemical" process of
inflammation.
What happens to your body when you lack sleep?
Sleep
deprivation has been linked to a variety of chronic health issues, including
heart disease, kidney disease, hypertension, diabetes, stroke, obesity, and
depression. Sleep deprivation has also been linked to an increased risk of
injury in adults, adolescents, and children.

Thus,
immune responses in humans are stronger in the second half of the night and early
morning hours. This is when inflammation is at its peak, and symptoms and
mortality rates are at their highest.
