Make the most out of Daylight Saving Time

This weekend, we spring ahead and lose an hour of sleep as part of Daylight Saving Time. For many people, this may create some problems only because they forgot to set their clock ahead before going to bed.

For those who tend to be night owls, shift workers, or who have sleep disorders, it can be more problematic. The additional loss of precious sleep can be a more substantial problem. When we are sleepy, we often don’t perform as well at work and are more likely to make mistakes and have car accidents.

Sleep key component to athletic performance

The world’s best athletes are descending upon Sochi, Russia for the 2014 Olympic Winter Games. Every elite athlete looks for an edge against their competitors to improve their athletic performance but what if the answer was as simple as getting more sleep?

According to Michael Howell, M.D., a sleep expert within the Department of Neurology, that’s precisely what elite athletes excel at.

“The best athletes I’ve ever met are extremely good sleepers,” said Howell. “Although you may not think your brain is doing much during sleep, your brain is putting connections together and it is amplifying circuits that are important.”

Study says sleep ‘cleans’ the brain of toxins

Last week, researchers from the University of Rochester Medical Center released a new study in the journal Science that demonstrated why fostering a healthy “waste removal system” may be one of the fundamental reasons for sleep. According to the study, brain cells shrink during sleep to open gaps between neurons and allow fluid to wash the brain clean.

The scientists used magnetic resonance imaging (MRI) in the brains of mice and found that the glymphatic system became 10 times as active while the mice were asleep. Brain cells shrink during sleep which increases the size of the interstitial space (gaps between brain tissue) allowing for more fluid to be pumped in and wash toxins away.

U of M sleep expert discusses the importance of a good night sleep for teens

Lack of sleep among teenagers is a rapidly developing issue and has researchers concerned about the harmful effects linked to it. Michael Howell, M.D., a sleep expert within the Neurology Department, appeared on Fox 9 to discuss the matter further.

“In general, teenagers should be getting at least two more hours of sleep than an adult,” Howell said. “The consequences of poor sleep are immense. Not only will teens actually be sleepy, but they’re prone to risky behavior and their academic performance goes down.”

These findings were some of the main reasons that sleep experts from across the country convened in the Twin Cities for a first ever national sleep conference devoted to teens, appropriately named Teens & Sleep
