How
Sleep Deprivation Leads to Cardiovascular Disease

Sleep
Deprivation is a condition where an individual does
not meet the required hours of sleep most of the time. It is a common problem among teenagers and adults. Although lack of
sleep does not lead to a serious health problem right away, doing it
repetitively can lead to physical and health problems gradually. Sleeping is
one of the basic needs that our body makes in order to regenerate good health
for both mental and physical aspect.

Sleep
Deprivation is a common health problem in the United
States. There is an appropriate sleep duration for each age group. According to
National Sleep Foundation, School-Age Children should be having 9-11 hours of
sleep, Teenagers 8-10 hours, and Adults for 7-9 hours. People who sleep less
than their recommended sleep duration are considered sleep deprived. In
addition, there is a survey conducted by The Centers for Disease Control and
Prevention in the year 2005-2009 that
according to it there an estimated of 50-70 million Americans that are Sleep
Deprived. Having sleep deprivation in a long run can result in increased
cardiovascular diseases such as heart attack, hypertension, and hormonal
imbalances.

            The effects of
sleep deprivation can increase a lot of health risk in the cardiovascular
system. Heart rate and blood pressure change during sleep. With lack of sleep,
this can put a lot of strain in the heart that makes
a heart works double time that can cause tachycardia and blood pressure.
Researcher Daniela Grimaldi, M.D., Ph.D. noted, “Almost all physiological and
behavioral processes, in particular, the
sleep-wake cycle, follow a circadian rhythm that is regulated by an internal
clock located in the brain.” This means that if we do not follow our internal
body clock sleep, it can cause dysfunction and serious problem in our
cardiovascular system and other parts of the body as well. Lack of sleep can
put a lot of stress in the body which can raise the blood pressure and can
cause a contraction in the blood vessels.
The elevation of blood pressure and contraction of the blood vessel can
decrease the function of the vagus nerve that has a restorative effect on the
function of the heart during resting or sleep state.

            Just one night of lack of sleep can result in increased
blood pressure. In one large study conducted by Institute of Medicine Committee
on Sleep Medicine and Research—that lack
of sleep and disordered sleep are also associated with heart attacks and
possible stroke. Getting 5 or fewer hours of sleep per night was associated
with a 45 percent increase of heart attack (the researcher controlled for age, weight,
smoking, and snoring)— (Colten HR and Altevog BM 2006)

During
sleep, the primary hormone that works is the melatonin. It is a hormone that is
released by the pineal gland that alerts an individual that the body needs to
sleep at night this hormone can also be suppressed by light. When an individual
is sleeping the bodies blood pressure drops. This reduces the workload of the
heart, but when an individual has an inadequate sleep there are several
hormones that can interrupt the sleep cycle. The hormones that work or can interrupt the sleep are Adrenaline,
Cortisol, and Thyroid hormones. Adrenaline is a strong hormone that can
directly affect the blood pressure. When
the adrenaline level remained high during the night this causes a big spike in
the blood pressure which can cause hypertension. Cortisol is known as “stress hormone” are highest in the
morning. Upon waking up, the cortisol level spikes up to prepare the body to
deal with the stress that it is going to face. The cortisol hormone levels are
very high in the morning and gradually declines throughout the day to prepare
the body for the resting state or sleep. But when the body is sleep deprived,
the cortisol level is disrupted that it increases in the night instead of the
morning and this makes the cycle messed up. This signals the body to do
unnecessary stress response that causes a negative
effect in the body.

Moreover,
Sleep Deprivation can affect the Thyroid hormone as well inadequate sleep can
increase the production of the thyroid of individuals that are not getting enough rest. An individual with increased thyroid hormone
causes increased blood pressure which can lead to hypertension or make the heart do unnecessary workload which
can lead to a heart attack as well.

There
are many ways which can help the body to overcome sleep deprivation, such as
going to bed at night and waking up every morning same time. This helps the
body to build a sleep-wake pattern. When going to bed, avoid intense activity
and as much as possible lessen the use of mobile devices or watching television
an hour before going to sleep because the light that comes from the devices may signal the brain that the body needs to
wake up. Avoid drinking caffeine before going to bed because the caffeine is a
stimulant that can disrupt the sleep. We know that banana has an excellent
source of magnesium and potassium which helps the bodies muscle to relax.
Furthermore, banana also contains a tryptophan that converts to serotonin and
melatonin that has a huge contribution to sleep. Lastly, after a long day of
stressful or tiring work that the body and mind goes through having a nice warm
bath or shower before going to bed helps the body relax and calm the muscles

            In conclusion, Sleep Deprivation is bad to our body it
can cause a lot of interference in our daily work such as having bad mood swings, the brain is not functioning
properly, fatigue, irritability, and so much more. This is only short outcomes in an occasional sleep deprivation, but in a
long run on having a habitual lack of sleep
it can affect our cardiovascular system which causes to hypertension, heart
attack, and hormonal imbalances that if left untreated may lead to death. Make
sure to have enough sleep daily for a productive
day and helps regenerate our body to protect our health and well-being.
