MEN WHO GET A GOOD NIGHT’S SLEEP MAY REDUCE THEIR RISK OF FATAL PROSTATE CANCER

Adequate sleep isn’t a luxury; it’s essential. And for men, it might even mean the difference between life and death, a preliminary study suggests.

Researchers found that men younger than 65 who slept just three to five hours a night were 55 percent more likely to develop fatal prostate cancer than those who got the recommended seven hours of shut-eye nightly.

And, six hours of sleep a night was linked to a 29 percent higher risk of prostate cancer death compared to seven hours.

“If confirmed in other studies, these findings would contribute to evidence suggesting the importance of obtaining adequate sleep for better health,” said lead study author Susan Gapstur, vice president of epidemiology at the American Cancer Society.

However, more research is needed to better understand the biologic mechanisms, said Gapstur. For now, she considers the study “intriguing” but not substantive enough to cause sleep-deprived males any alarm.

Still, the findings contribute to the evidence that the body’s natural sleep/wake cycle — circadian rhythms — might play a role in prostate cancer development, Gapstur said.

The study results stem from an analysis of long-term data on more than 823,000 men in the United States. The findings were scheduled for presentation Monday at the annual meeting of the American Association for Cancer Research, in Washington, D.C.

Lack of sleep can inhibit production of melatonin, a hormone that affects sleep cycles. Low melatonin production can lead to an increase in genetic mutations, greater oxidative damage, reduced DNA repair and a weakened immune system, Gapstur said in an association news release.

Lack of sleep may also contribute to the disruption of genes involved in tumor suppression, she added.

It’s not clear why the link between limited sleep and higher death risk from prostate cancer wasn’t seen in men 65 and older. But, Gapstur suggested that the natural decline in nocturnal melatonin levels with age might possibly reduce the relative impact of lack of sleep.

The National Sleep Foundation recommends adults get at least seven hours of sleep a night.

Research presented at meetings should be considered preliminary until published in a peer-reviewed medical journal.

About Mastering You

"Mastering You" is about helping African American's to see their value in this world. I post only positive stories and information about what African American's have contributed to society in the past and currently. I don't post anything about Sports, Entertainment, Religion, or Politics. I also don't post anything that has a negative spin. While I am aware that there are negative things happening all over the world and that most people focus on the above four topics when it comes to African American's that is not my goal. If all you heard was negativity about any race that's all you will come to expect from them and everything else will be out of the norm. My goal is to show everyone that the negativity is often out of the norm, or at best they are equal to the positive. Just like every other race.
