- Not sleeping enough can
     compromise our immune system.
 
•     
We
eat well and exercise in order to keep our immune system up.
•     
But
if we are not sleeping, we undo all the good work.
•     
The
immune system works best when we are sleeping.
- It can cause malfunctioning of
     natural killer cells.
 
•     
These
cells are produced in the bone marrow and are found in the blood and lymph.
•     
They
are part of the body’s defence system.
•     
They
do not work properly in the persons who are sleep-deprived.
•     
This
leaves our bodies undefended and susceptible to infection.
      3.   Heart failures.
•     
There
is a higher rate of heart failure among people with sleep disorders and
disturbances.
•     
There
is an increased evidence of C-reactive protein, an indicator of heart disease
risk, in people suffering from sleep loss.
     4.   It
causes problem of regulation of hormones.
•     
Chronic
sleep loss can reduce the body’s ability to regulate hormones and process
carbohydrates.
•     
Sleep
disturbances increase the likelihood of pre-diabetic state of glucose
intolerance and insulin resistance.
•     
Sleep
is also important for ensuring a balanced brain activity.
•     
During
sleep, brain neurotransmitters are replenished.
•     
When
we do not sleep well, our brain chemicals become depleted which leads to
emotional disturbances like-
•     
Depression
•     
Anxiety
•     
General
feelings of sadness
•     
Anger
and Irritation
