Sleep May Aid in Brain Repair, Mouse Study Finds

Meanwhile, sleep deprivation appeared to harm brain cells

The reproduction of cells involved in brain repair is boosted during sleep, according to a new study of mice.

Researchers from the University of Wisconsin, Madison, found that sleep increases the process by which certain cells, known as oligodendrocytes, form myelin. Myelin is the insulation on nerve cells in the brain and spinal cord that allows electrical impulses to move rapidly from one cell to another.

In conducting the study, published in the Sept. 4 ...

Sleep Deprivation May Disrupt Your Genes

But small study doesn’t explain how that works or effects on health.

Far more than just leaving you yawning, a small amount of sleep deprivation disrupts the activity of genes, potentially affecting metabolism and other functions in the human body, a new study suggests.

It’s not clear how your health may be affected by the genetic disruption if you don’t get enough sleep. Still, the research raises the possibility that the effects of too little sleep could have long-lasting effects on your ...

Sleep Apnea Treatment Linked to Improved Appearance

New research shows that people who stick to a treatment for sleep apnea end up looking more alert, youthful and attractive.

The most effective treatment for sleep apnea — continuous positive airway pressure (CNAP) therapy — requires users to wear a mask connected to a machine all night. Since this is burdensome, many people eventually stop CNAP, but a new finding suggesting that the therapy improves physical appearance may convince people to plug back in.

Researchers from the University of Michigan took ...

Sleep Apnea Raises Risk For Hard-To-Treat Hypertension

People with severe sleep apnea are at a higher risk for high blood pressure that does not respond to medication, according to preliminary new research.

Researchers looked at 284 people with sleep apnea and found that ...

Sleep Affects Concussion-Testing Results, Study Finds

Athletes with the least shuteye had lower baseline scores.

Getting too little sleep the night before undergoing baseline concussion testing can skew results, a new study finds.

Baseline concussion testing depicts an athlete’s basic mental abilities, such as reaction time, working memory and attention span. Athletes who suffer a concussion retake the test, and if there is a large decrease in the score, they are typically banned from play until their score improves.

The study included more than 3,600 high school- and college-aged ...

Poor Sleep in Old Age Linked to Forgetfulness

Researchers at UC Berkeley found deep ‘slow wave’ sleep could restore memory as we age.

Improving sleep quality could provide a memory boost in older people who may have difficulty remembering things like people’s names, according to neuroscientists at the University of California, Berkeley.

For their study, the researchers tested memory in 18 healthy adults mostly in their twenties, and 15 healthy adults in their seventies after a full night’s sleep. Before going to sleep, participants learned and were tested on 120 ...

Poor Nutrition Can Bite Into Your Sleep

Researchers found that certain nutrients may play a role in sleep duration. And they also concluded that people who eat a wide variety of foods (an indicator of an overall healthy diet) had the healthiest sleep patterns.

“Although many of us inherently recognize that there is a relationship between what we eat and how we sleep, there have been ...
