Getting less than seven hours' sleep a night 'could damage DNA beyond repair'

Researchers studied doctors in Hong Kong, some of whom worked night shifts. A lack of sleep was shown to increase DNA damage by up to 30 per cent.

ConclusionsRestoration of knee joint homeostasis is essential to cruciate ligament recuperation, micro-trauma repair, and remodeling. The nervous and immune systems are intricately involved in this process. Varying combinations of high-intensity training, under-recovery, technostress, and environmental pollutants (including noise) regularly expose many athletically active individuals to factors that abrogate the environment needed for cruciate ligament recuperation, micro-trauma repair, and remodeling. Current sports training practice, lifestyle psychobehaviors, and environmental factors combine to increase both primary no...

This study provides a possible reason why genes carrying health risks have persisted in human populations. The second found evidence for multiple variants in genes related to ageing that exhibited antagonistic pleiotropic effects. They found higher risk allele frequencies with large effect sizes for late-onset diseases (relative to early-onset diseases) and an excess of variants with antagonistic effects expressed through early and late life diseases. There also exists other recent tangible evidence of antagonistic pleiotropy in specific human genes. The SPATA31 gene has been found under strong positive genomic sele...

Chromosomes ’ movement when the brain is resting allows cells to mend DNAErnest Hemingway prized sleep for good reason. Not one to dwell on rest and recuperation, the novelist saw snoozing as a form of damage limitation. “I love sleep,” he once said. “My life has the tendency to fall apart when I’m awake.”The author ’s observation may be truer than he imagined. Scientists have discovered that broken DNA builds up in brain cells in the daytime and repair work reverses the damage only during sleep.Continue reading...

(CNN) — Wake up, America, and raise your hand if you try to repair your exhausted body by sleeping in on weekends. A new study says the habit may not be such a good idea for your waistline — or your health. “Weekend catch-up sleep is not protective,” said Dr. Vsevolod Polotsky, director of sleep research at the Johns Hopkins University School of Medicine. “The bottom line of this study is that even if you sleep longer on weekends, if you continue to sleep poorly, you will still eat too much, and you will still gain weight.” The common behavior of “sleeping in on the weekends doesn&...

When Tom Shicowich’s toe started feeling numb in 2010, he brushed it off as a temporary ache. At the time, he didn’t have health insurance, so he put off going to the doctor. The toe became infected, and he got so sick that he stayed in bed for two days with what he assumed was the flu. When he finally saw a doctor, the physician immediately sent Shicowich to the emergency room. Several days later, surgeons amputated his toe, and he ended up spending a month in the hospital to recover. Shicowich lost his toe because of complications of Type 2 diabetes as he struggled to keep his blood sugar under control. He wa...

If you shower before bed, you’ve probably wondered whether sleeping with damp hair is a problem. Maybe you’ve heard it could make you sick, or that it can damage your hair or skin. What’s the truth? Let’s address the “it can make you sick” myth first. “This idea seems to fit into the old bit of folklore that getting yourself chilled and wet will cause you to come down with a cold,” says Dr. William Schaffner, a professor of medicine in the Division of Infectious Diseases at Vanderbilt University Medical Center. While this idea persists, Schaffner says it was long ago disprove...
