Check out the benefits of quality sleep to your body.
While some people get into the regular workout and breathing routines, many
neglect the third factor that completes the trifecta: good quality sleep.
Your Body Needs 7 to 8 Hours of Sleep
More than 15 years ago, studies told us that
getting 6 hours of sleep daily is enough. However, in the last decade, many
studies have shown that for people to function well and maintain good health,
they need to have 7 to 8 hours of sleep a day, with 8 hours giving the most
health benefit. Unfortunately, statistics tell us that Americans spend only an
average of 6.5 hours of sleep a day[1]. This is no
surprise, considering the distractions that surround us: TV, the Internet,
social media, and others. We always seem to be doing something.
In our busyness, the first thing that usually gets
sacrificed is the time we spend for sleep. To cram as many activities as we can
during the day, we cut back on our sleeping hours. Some people think that sleep
is a luxury they can’t afford, and they conveniently sacrifice their sleeping
hours to do more things, believing that losing a few hours of sleep is nothing
compared to what they are able to accomplish because of it. Unfortunately, if
you think this way, you overlook the negative long-term consequences of
inadequate sleep on your health and total well being.
If you are serious about losing weight and staying
healthy, you must keep in mind that not getting the right amount of sleep
affects your health negatively, and the consequences can worsen over time. For
you to understand this better, you have to know what good quality sleep
actually does to your body.
Adequate Sleep Improves Your Mind’s Performance
Sleeping undisturbed for 7 to 8 hours every day
will give you an alert mind[2]. It allows
your mind to maintain focus for prolonged periods of time. In other words, you
are able to concentrate more at work, such as during long meetings, when you
are writing important reports, or when you are reading for a prolonged period
of time. People with 7 to 8 hours of sleep can sit down and concentrate longer
than those who are sleep deprived.
On the other hand, those who sleep for less than 7
hours a day have difficulty focusing and analyzing things, and over time, the
effect worsens. Memory weakens and judgment becomes impaired. Some studies have
shown that those who suffer from lack of sleep can’t even tell that the
performance of their mind has deteriorated even though the results of their
tests indicate that it has; they claim that they are still the same.
Adequate Sleep Helps Your Body to Recover
Good quality sleep also helps your body to recover
from your workout. When the body is asleep, it turns into an anabolic state, or
the state in which it conserves energy, and the growth and repair of muscles
take place[3]. Allowing
the body to recover from your workout is very important. When you train, your
muscle tissues suffer from small damages. If your body has not recovered well
and you continue to train, you push it into a strenuous condition. Your
performance and your health will deteriorate instead of improve. Working out
when you are sleep deprived is disastrous to your health. Get the proper amount
of sleep and let your body heal and repair itself.
Adequate Sleep Strengthens Your Immune System
Having good quality sleep for 7 to 8 hours a day
strengthens your immune system and makes your body more resistant to sickness
and disease. Poor sleep, on the other hand, weakens your body over time and
makes it more susceptible to diseases like diabetes, obesity, hypertension, and
cardiovascular disease. Sleep deprived people are also three times more
susceptible to the common cold. Some studies have shown that sleeping for just
5 hours or less per day increases one's mortality risk by up to 15%.[4] Sleep
deprivation has also been linked to the development of mental disorders like
Alzheimer’s disease[5],
schizophrenia, and depression[6].
It is very clear that getting sufficient sleep impacts the body just as much as
having proper exercise and nutrition, and should be taken more seriously.
Adequate Sleep Helps You to Maintain or Lose Weight
A number of studies have shown that sleep
deprivation causes weight gain. This is in part because lack of sleep leads to
increased levels of ghrelin, the hormone that signals the body to take in more
calories, and decreased levels of leptin, the hormone that suppresses appetite.
As a result, the sleep deprived individual eats more. One study, in particular, showed that those who slept less tended to reach for carbohydrate rich foods
for their late-night snack[7].
Adequate Sleep Makes Your Look Good
Adequate sleep also improves your physical
appearance. BMJ published a study[8] that was
conducted to determine whether people who lacked sleep were perceived as being
less healthy and less attractive. The study concluded that sleep deprivation
affects one's physical appearance. Lack of sleep makes people look tired and
less healthy, and therefore less attractive.
All in all, having a good quality sleep every day
gives you a sharper mind, longer life span, a stronger body, and better physical
appearance. Adequate sleep decreases your risk of developing diseases
dramatically, so never take sleep for granted. If you combine good quality
sleep with proper nutrition and regular exercise, you can be assured of better
health, and you lessen the need for dietary supplements.
If it has been your habit to cut back on your
sleeping hours, you have to stop doing that right now. There are no studies yet
citing how many hours we need to catch up on the sleep we lost and restore our
health, but it surely takes more than one weekend to reverse the effects of our
sleep loss during the entire week. One can only imagine how years of sleep
deprivation can affect one's health.
How Can You Get Good Quality Sleep?
Some people do not get the required amount of
sleep because they have trouble sleeping. Stress and worry are among the top
causes of sleeplessness. Other factors include not having enough physical
activity, not spending enough time outdoors, poor sleeping conditions, drinking
alcohol, and others.
To help you sleep better at night, you need to
have some regular physical activity. Exercise helps your body in many ways.
First, it decreases the levels of the stress hormone cortisol and increases the
levels of the “happy hormone” endorphin, which improves mood. Second, it boosts
your energy during the day and helps your body to easily go into rest mode at
night.
You also need to spend some time outdoors during the early morning for you to get sunlight exposure. Early morning sunlight has an
important role in the sleep—wake cycle; it regulates your internal biological
clock and signals your brain that it's morning[9]. Because of
this, your internal clock is able to keep track of the time, and it knows when
it's time to sleep. Daily exposure to sunlight, ideally from 6:30 to 8:00 in
the morning, for about 30 minutes keeps your internal clock intact. It also
enables you to wake up and sleep at the same time each day.
For better sleep, avoid drinking alcohol before
you hit the sack. Alcohol does not help you sleep better; it actually
diminishes sleep quality[10].
Therefore, it is not to be taken to induce sleep, and ideally should not be
ingested right before bedtime. You should also check if the temperature in your
bedroom is comfortable enough. Most people sleep comfortably at 68 to 70
degrees, but this may vary for each individual, so adjust the temperature
according to your preference. If concerns for the following day keep popping in
your mind and prevent you from dozing off, keep a small notebook by your
bedside so you can write them down and get back to them in the morning.
An undisturbed sleep of 7 to 8 hours every day is
imperative for good health, so do whatever you can to improve your sleep. After
all, you don't just want to lose weight, you also want to be healthier.
