So what you think how many hours sleep is good for everyone?
Here are some contradicting studies:
Study a- Less than 8 hours Sleep is good-
A recent study done by the University of California and the shocking finding of it: "People who sleep 8 hours or more have a 50% higher mortality (death) rate than people who sleep less." Yes, it's true that such a study was carried out; however, does this mean that sleeping longer will create a higher chance of death and disease for you?
No. There's no solid proof for that, but as you read about this study in I sent you from our Powerful Sleep eBook, you might have realized the connection between less sleep, your daily energy levels, and the strength of your immune system.
As you might notice, it's during deep sleep that your body undergoes major physiological changes to repair your muscles, power up your immune system and replenish your energy.
The question really isn't "how long should I sleep?" The question really is...
"How can I optimize my sleep system to gain POWERFUL and QUALITY sleep?"
There are several reasons why sleeping longer damages your sleep system. What most people don't know is that there is a very important element of your inner sleep clock which is prior wakefulness. When you sleep longer you limit your prior wakefulness which puts stress on a number of other factors such us your melatonin hormone levels, your exposure to sunlight, and your body temperature rhythm
MYTH #2) you need to “Catch Up on Sleep” if you missed some before.
TRUTH: Unless you go on a huge sleep deprivation marathon, you do not need to "catch up on sleep".
MYTH #3) “I feel so low on energy, I Must Get More Sleep”
TRUTH: More Sleep DOES NOT Provide you with more Energy! You don't need MORE sleep, you need QUALITY sleep.

Sleep can be categorize into two cycles “Light Sleep” and “Deep Sleep”
During our first 3-4 hours of our sleep that we experience the longest period of Stage 3 and Stage 4 sleep. Stage 3 and Stage 4 Sleep is also commonly termed "deep sleep."
It's during deep sleep that we experience very low brain waves called Theta and Delta brain waves.
Our blood vessels dilate and all the blood that is usually stored in our organs throughout the day moves into our muscles to nourish and repair them.
Our immune system also activates during deep sleep to fight disease. This is why people tend to sleep longer when they're sick.
When you don't take proper care of your inner sleeping system, you're usually at risk of "poor sleep." Poor sleep happens for a variety of reasons which I outline in the Powerful Sleep book, but the main "symptom" is the inability or the difficulty of obtaining proper amounts of "deep sleep."
Study b-More sleep is good for our body:
Sleeping you to good health: those people who can clock up seven hours of shut-eye a night can slash the risk of health problems
Long-term studies show that those who drop down to five hours or fewer face a 70 per cent extra risk of dying from all causes.
They also face twice the risk of death from a cardiovascular problem.
However, getting more than seven hours can also be a risk, according to the study by the University of Warwick and University College London.
Those who slept for eight hours or more a night were more than twice as likely to die as those who had not changed their habits.
The study looked at how sleep patterns affected death rates among 10,308 subjects, mainly white-collar civil servants.
Researchers examined data for 1985-8 and for those still alive in 1992-3.
Once adjustments were made for factors such as age, smoking and illness, the study was able to isolate the effect of changes in sleep patterns.
The average night's sleep is seven hours but around a third of adults in Britain regularly sleep five hours or fewer a night.
Professor Francesco Cappuccio, of the University of Warwick medical school, said: "Fewer hours of sleep and greater levels of sleep disturbance have become widespread in industrialised societies.
"This change, largely the result of sleep curtailment to create more time for leisure and shiftwork, has meant that reports of fatigue, tiredness and excessive daytime sleepiness are more common. Sleep represents the daily process of physiological restitution and recovery, and lack of sleep has far-reaching effects.
"Our findings indicate that consistently sleeping around seven hours per night is optimal for health."
He said insufficient sleep was a risk factor in weight gain, high blood pressure and type 2 diabetes.
But it is unclear how sleeping too long could cause ill-health, he added, although possible causes included depression and low socio-economic status.
Last week, researchers showed that children who did not get enough sleep were more likely to become obese as adults

Typical Sleep Needs
Infants
About 16 hours per day of sleep
Babies and toddlers
From 6 months to 3 years: between 10 and 14 hours per day. Infants and young children generally get their sleep from a combination of nighttime sleep and naps.
Children
Ages 3 to 6: between 10 and 12 hours of sleep
Ages 6 to 9: about 10 hours of sleep
Ages 9 to 12: about 9 hours of sleep
Teenagers
About 9 hours of sleep per night. Teens have trouble getting enough sleep not only because of their busy schedules, but also because they are biologically programmed to want to stay up later and sleep later in the morning, which usually doesn’t mesh with school schedules.
Adults
For most adults, 7 to 8 hours a night appears to be the best amount of sleep.
Older adults
Older adults are also thought to need 7-8 hours of sleep. However, this sleep may be for shorter time spans, is lighter than a younger adult’s, and may include a nap during the day. See Sleep & Aging for more detailed information.
Pregnant women
During pregnancy, women may need a few more hours of sleep per night, or find that they need small catnaps during the day
