Sleep Needs
How many hours of sleep do you require? What happens when you don’t get sufficient? Explore the stages of sleep and how to get on a well sleep schedule.
Why is sleep so important?
The quality of your sleep straight affects your mental and
physical health and the excellence of your waking life, including your output,
emotional balance, intellect and heart health, immune system, creativity,
vitality, and even your weight. No other activity delivers so many benefits
with so little endeavor!
When you’re scramble to meet the demands of a busy programme,
though, or just finding it hard to sleep at night, getting by on less hours may
seem like a good clarification. But even minimal sleep loss can take a considerable
toll on your mood, energy, mental sharpness, and ability to handle stress. And
over the long-term, continual sleep loss can wreak havoc on your mental and
physical health.
Sleep isn’t only a time when your body shuts off. While you
rest, your brain stays busy, supervision biological maintenance that keeps your
body running in top condition, preparing you for the day ahead. Without enough
hours of healing sleep, you won’t be able to work, learn, create, and converse
at a level even close to your true potential. Regularly skimp on “once-over”
and you’re headed for a major mental and physical breakdown.
The good news is that you don’t have to choose between physical
condition and productivity. By addressing any sleep problems and making time to
get the sleep you need each night, your energy, competence, and overall health
will go up. In fact, you’ll likely get much more done during the day than if
you were skimping on shut eye and trying to work longer.
Tradition and Facts
about Sleep
Saga:
Getting just one hour less sleep per night won’t affect your daytime
functioning.
Detail: You may not be
noticeably sleepy during the day, but trailing even one hour of sleep can
affect your ability to think properly and respond quickly. It also compromises
your cardiovascular physical condition, energy balance, and ability to fight
infections.
Saga: Your body adjusts quickly to different sleep schedules.
Fact: Most people can
reset their biological clock, but only by appropriately timed cue and even
then, by one or two hours per day at best. Consequently, it can take more than
a week to adjust after travelling across several time zones or switch to the
night shift.
Fact: The quantity of
sleep you get is imperative, sure, but it’s the quality of your sleep that you
really have to pay attention to. Some people sleep eight or nine hours a night
but don’t feel healthy rested when they wake up because the quality of their
sleep is pitiable.
Myth: You can make up for
lost sleep during the week by sleep extra on the weekends.
Fact: Although this
sleeping outline will help relieve part of a sleep debt, it will not completely
make up for the lack of sleep. Furthermore, sleeping later on the weekends can change
your sleep-wake cycle so that it is much harder to go to sleep at the correct
time on Sunday nights and get up early on Monday mornings.
How many hours of sleep
do you need?
There is a big difference between the amount of sleep you
can acquire by on and the amount you need to function optimally. According to
the National Institutes of Health, the average adult sleeps less than seven
hours per night. In today’s fast-paced society, six or seven hours of sleep may
sound attractive good. In reality, though, it’s a recipe for chronic sleep
deprivation.
Just because you’re able to operate on six or seven hours of
sleep doesn’t mean you wouldn’t feel a lot better and get more done if you tired
an extra hour or two in bed.
While sleep requirements vary slightly from person to person, most healthy adults need between 7 to 9 hours of sleep per night to task at their best. Children and teens need even more. And despite the notion that our sleep needs decrease with age, older people still need at least 7 hours of sleep. Since older adults often have trouble sleeping this long at night, daytime naps can help fill in the gap.

The best way to figure out if you’re meeting your sleep
needs is to evaluate how you feel as you go about your day. If you’re logging
enough sleep hours, you’ll feel energetic and alert all day long, from the instant
you wake up until your regular bedtime.
Think six hours of
sleep is enough?
Think again. Researchers at the University of California,
San Francisco, discovered that some people have a genetic material that enables
them to function well on six hours of sleep a night. This genetic material,
however, is very rare, appearing in less than 3% of the population. For the
other 97% of us, six hours doesn’t come close to cutting it.
The importance of deep
sleep and REM sleep
It’s not just the number of hours you expend asleep that’s
important it’s the quality of those hours. If you give yourself plenty of time
for sleep but still have trouble waking up in the morning or staying alert all
day, you may not be spending sufficient time in the different stages of sleep.
Each stage of sleep in your sleep cycle offers different
benefits. However, deep sleep (the time when the body maintenance itself and
builds up energy for the day ahead) and mind and mood-boosting REM sleep are
particularly important. You can ensure you get more deep sleep by avoiding
alcohol, nicotine, and being woken during the night by noise or light. While getting
better your overall sleep will increase REM sleep, you can also try sleeping an
extra 30 minutes to an hour in the morning, when REM sleep stage are longer.

Signs that you’re not
getting enough sleep
If you’re getting less than eight hours of sleep each night,
chances are you’re sleep destitute. What’s more, you probably have no idea just
how much lack of sleep is affecting you.
How is it possible to be sleep deprived without knowing it?
Most of the signs of sleep deprivation are much slighter than falling face
first into your dinner plate. Furthermore, if you’ve made a habit of thrifty on
sleep, you may not even remember what it feels like to be truly wide-awake,
fully alert, and firing on all cylinders. Maybe it feels normal to get sleepy
when you’re in a boring meeting, struggling through the afternoon slump, or
dozing off after dinner, but the truth is that it’s only “ordinary” if you’re
sleep deprived.
You may be sleep deprived
if you…
Need an alarm clock in order to wake up on time
Rely on the snooze button
Have a hard time getting out of bed in the morning
Feel sluggish in the afternoon
Get sleepy in meetings, lectures, or warm rooms
Get drowsy after deep meals or when driving
Need to nap to get through the day
Fall asleep while watching TV or calming in the evening
Feel the need to sleep in on weekends
Fall asleep within five minutes of going to bed
The effects of sleep
deprivation
While it may seem like losing sleep isn’t such a big deal,
sleep deprivation has a wide range of negative effects that go way beyond
daytime drowsiness. Lack of sleep affects your judgment, coordination, and
reaction times. In fact, sleep deprivation can affect you just as much as being
intoxicated.
The effects include:
Fatigue, weariness, and lack of motivation
glumness and bad temper; increased risk of depression
Decreased sex drive; relationship problems
Impaired brain activity; learning, concentration, and memory
problems
Reduced creativity and problem-solving skills; difficulty
making decisions
Inability to cope with stress, difficulty managing emotions
Premature skin aging
Weakened immune system; frequent colds and infections;
weight gain
impair motor skills and increased risk of accidents;
hallucinations and delirium
Increased risk of serious health problems including stroke,
diabetes, high blood pressure, heart disease, Alzheimer’s disease, and certain
cancers
How sleep deprivation
can add to your waistline
Ever noticed how when you’re short on sleep you crave sugary
foods that give you a quick energy boost? There’s a good reason for that. Sleep
deprivation has a direct link to overeating and weight gain.
There are two hormones in your body that control normal
feelings of hunger and tastiness. Gherkin stimulates appetite, while lepton
sends signals to the brain when you are full. However, when you don’t get the
sleep you need, your gherkin levels go up, stimulating your appetite so you
want more food than normal, and your lepton levels go down, meaning you don’t
feel satisfied and want to keep eating. So, the more sleep you lose, the more
food your body will crave.
How to get the sleep
that you need
Whether you’re looking to resolve a specific sleep problem,
or just want to feel more productive, mentally sharp, and expressively balanced
during the day, experiment with the following sleep tips to see which work best
for you:
Rule out medical causes for your sleep problems. A sleep trouble
may be a symptom of a physical or mental health issue, or a side-effect of
certain medications.
Stick to a regular sleep agenda. Support your biological
clock by going to bed and getting up at the same time every day, including
weekends.
Get regular exercise. Regular exercise can improve the
symptoms of many sleep disorders and problems. Aim for 30 minutes or more of
activity on most days—but not too close to bedtime.
Be smart about what you eat and drink. Caffeine, alcohol,
and sugary foods can all disrupt your sleep, as can eat heavy meals or drinking
lots of fluids too close to bedtime.
Get help with stress management. If the stress of managing
work, family, or school is keeping you awake at night, learning how to handle
stress in a creative way can help you sleep better at night.
Improve your sleep environment. Keep your bedroom dark,
quiet, and cool, and reserve your bed for just sleeping.
Develop a relaxing bedtime routine. Avoid screens, work, and
stressful conversations late at night. Instead, wind down and calm your mind by
taking a warm bath, reading by a dim light, or practicing a recreation
technique to prepare for sleep.
Postpone disturbing. If you wake during the night feeling anxious about something, make a brief note of it on paper and postpone disturbing about it until the next day when it will be easier to resolve the issues.
