Insomnia: Sleep Disorder > How Much Of Sleep Do You Really Need?
An adult needs an average of eight hours of sleep every night.
Where do you think this magic number comes from?
In 1993, a study conducted by Thomas Wehr at the National Institutes of Health in Bethesda concluded that eight hours is the optimal amount of sleep you really need each night.
In this study, 16 volunteers lay in bed in a darkened room for 14 straight hours a day for four weeks.
At first, the volunteers slept for more than 12 hours a day on average.
After a few weeks, most reduced their sleep time to somewhere between seven and a half to nine hours.
But, this research does not tell you how much sleep is crucial for your good health.
It only indicates the number of hours a person will sleep when he has nothing else to do.
Another reason why this number is important because your brain takes around eight hours to re-energizes your body while you sleep.
When your brain could not complete its night time duties, you will not be able to perform at your best the next day.
How much sleep you need changes over your lifetime.
Newborn babies usually sleep for about 17 hours each day while older children need 9 or 10 hours a night.
And adults sleep about 7 to 8 hours each night.
As you gets older, you will need the same amount of sleep but only have the first 3 or 4 hours of deep sleep during the night making you easily awaken after 5 hours of sleep.
You are the best person to know what it is like to inhabit your body.
If, all this while you have been sleeping for 10 hours every night and did not feel terrible about it, you should continue with this sleep routine.
Do not stumble around exhausting yourself and feeling miserable the next morning just because a study tells you that you really need eight hours of sleep each night.
Even if you have slept less than eight hours each night and feel great about it, you should still continue with this sleep routine.
You may have one night of insomnia or the whole week of it, research shows that the number of sleep hours you get throughout the year usually averages out to a normal amount.
Try your best to get a decent amount of sleep you can and not to let the eight hours sleep myth keep you up all night.

Prostate And 7 Cups Of Tea Per Day
Prostate Cancer > Prostate And 7 Cup Of Tea Per Day
If your drink 7 cups of tea per day, you are 50 per cent more likely to develop prostate cancer according to a controversial study by Dr Kashif Shafique of Glasgow University's Institute of Health and Wellbeing.
The study observed more than 6,000 male volunteers over a period of 37 years
The findings were published in the journal Nutrition and Cancer.
This contradicts previous research study published in the Journal of the American Association for Cancer Research that men with prostate cancer who consumed the active compounds in green tea shows a significant reduction in serum markers predictive of prostate cancer progression.
The researchers from Scotland point out that their study was not designed to find fault although their study shows that heavy tea drinking is linked to a higher risk for prostate cancer, it is not necessarily the cause of it.
They also admitted to being surprised at the link as heavy tea drinkers are,
* Unlikely to be overweight
* Do not consume alcohol
* Have healthy cholesterol level
To lower your risk of developing prostate cancer, you should reduce your consumption of green tea by one cup per day.
The tea industry rejected the Glasgow University's findings citing previous studies found that there is no link between black tea and prostate cancer.
The Tea Advisory Panel, a health information body funded by the UK Tea council highlight seven other studies concluded in the complete opposite result.
The Panel said the research was flawed as the higher incidence of prostate cancer could be attributed to other factors such as smoking, stress or diet.
If the researchers take into account of the participants’ age, health and lifestyle, they would found those heavy tea drinkers were 50 per cent more likely to develop the disease.
Dr Kashif Shafique, who led the research, said "We do not know whether tea itself is a risk factor or if tea drinkers are generally healthier and live to an older age when prostate cancer is more common anyway."
However, they have admitted they do not know if the link is just a coincidence; it might be that the heavy tea drinkers just lived to an age when prostate cancer is more common.
But Dr Bill Gorman, chairman of the UK Tea Council, which represents the industry, said: "I notice that Dr Shafique has said that he doesn't know if it is tea itself which increases the likelihood of prostate cancer."
Head of research Dr Kate Holmes pointed out: "The study" did not take into consideration family history or any other dietary elements other than tea, coffee and alcohol intake.
"It is therefore unclear as to whether there were other factors in play which may have had a greater impact on risk."
In the ten years leading up to 2010, the incidence of prostate cancer in Scotland went up by 7.4%. It is the most common cancer amongst Scottish men.
