BENEFITS OF SLEEP
The benefits of sleep impact nearly every area of our daily
lives. While it may be obvious that sleep is beneficial, most people don’t
realize how much sleep they need and why it is so important. According to the
Division of Sleep Medicine at Harvard Medical School, your body manages and
requires sleep in much the same way it regulates the need for food, drinking
and breathing. Extensive research has been done on the effects of sleep. These
studies have consistently shown that sleep plays a vital role in promoting
physical health, longevity and emotional well-being.
Sleep Helps to Repair the Body
Your body produces extra protein molecules while you are sleeping
that help strengthen your ability to fight infection and stay healthy. These
molecules help your immune system mend your body at the cellular level when you
are stressed, or have been exposed to compromising elements such as pollutants
and infectious bacteria.
Sleep Helps Keep Your Heart Healthy
Your cardiovascular system is constantly under pressure and
sleep helps to reduce the level of stress and inflammation in your body. High
levels of “inflammatory makers” are linked to heart disease and strokes. Sleep
can also keep blood pressure and cholesterol levels (which play a role in heart
disease) in check.
Sleep Reduces Stress
A good night sleep can help lower pressure and elevated
levels of stress hormones, which are a natural result of today’s fast paced
lifestyle. High blood pressure can be life threatening and the physical effects
of stress can produce “wear and tear” on your body, and degenerate the cells
which propel the aging process. Sleep helps to slow these effects and
encourages a state of relaxation.
Sleep Improves Your Memory
The foggy feeling that you struggle with when deprived of
sleep makes it difficult to concentrate. This often leads to memory problems
with facts, faces, lessons or even conversations. Sleeping well eliminates
these difficulties because, as you sleep, your brain is busy organizing and
correlating memories. One of the great benefits of sleep is that it allows your
brain to better process new experiences and knowledge, increasing your
understanding and retention. So, next time you hear someone say, “Why don’t you
sleep on it?” Take the advice.
Sleep Helps Control Body Weight Issues
Sleep helps regulate the hormones that affect and control
your appetite. Studies have shown that when you are deprived of sleep, the
normal hormone balances are interrupted and your appetite increases.
Unfortunately, this increase in appetite doesn’t lead to a craving for fruits
and veggies. Rather, your body longs for foods high in calories, fats and
carbohydrates. So, if you are trying to lose those stubborn few kilograms that just
keep hanging around, consider the benefits of sleep each day. Research has also
shown that lack of sleep may lead to type 2 diabetes by affecting how your body
processes glucose, which is the carbohydrate your cells use for fuel. The
Division of Sleep Medicine at Harvard Medical School reports that a study
showed a healthy set of people who have reduced their sleep from eight to four
hours per night processed glucose more slowly. Other research initiatives have
revealed that adults who usually sleep less than five hours per night have
increased risk of developing diabetes.
With sufficient sleep during the night, many people still
become agitated or moody the following day. When limited sleep becomes a
chronic issue, it can lead to long-term mood disorder such as depression and
anxiety.
The benefits of sleep are extensive and can make a difference
in your quality of life, as well as the length of your life. Therefore, it is
vital to place a priority on getting ample and consistent sleep.
