Sleep Deprivation Is Killing You and Your Career

,

The next time you tell yourself that you’ll sleep when you’re dead, realize that you’re making a decision that can make that day come much sooner. Pushing late into the night is a health and productivity killer.

According to the Division of Sleep Medicine at the Harvard Medical School, the short-term productivity gains from skipping sleep to work are quickly washed away by the detrimental effects of sleep deprivation on your mood, ability to focus, and access to higher-level brain functions for days to come. The negative effects of sleep deprivation are so great that people who are drunk outperform those lacking sleep.

Feeling Anxious or Depressed? Sleep Deprivation May Be to Blame

,

Feeling emotionally overwhelmed during times of stress and can't figure out why? Your current sleeping habits might offer some helpful insight.

According to findings in Sleep and Affect: Assessment, Theory and Clinical Implications, a new book from University of Arkansas psychology professor Matthew Feldner and National Center for Post Traumatic Stress Disorder health science specialist Kimberly Babson, we are more likely to react emotionally to stressful situations when we are sleep deprived.

Previous research has linked sleep loss with anxiety and mood disorders, so this additional study corroborated those results as well as expanded symptom observation beyond anxiety and depression specifically.

10 Habits You Should Ditch Now to Bring Productivity to an All-Time High

They say that you have the same number of hours in the day as Beyonce -- so why does it feel like you’re never able to get caught up on your business to-do list?

Apart from not having your own team of personal assistants, stylists and other hangers-on, it could be your habits that are keeping you from achieving your business goals. Fortunately, habits can be broken.

Here are 10 habits you should ditch right away to improve your productivity:

Dreaming of More Creative, Productive Employees? Let Them Sleep In

,

“How did you sleep last night?”

We often ask our family members and house guests this question over breakfast. But should business leaders be just as concerned about how well—and how much—their employees are sleeping?

Research into the science of sleep has proven what most people figure out through life experience: When we don’t get enough shuteye, we’re not our best selves. We aren’t as alert, focused, or creative as we are after a restful night. Instead, we’re crankier, more impatient, and less enthusiastic—about both life and work.

Sleep Scientists Want Your Workdays to Start Later

,

A team of sleep scientists have an idea and I think we'd better hear them out: One way to ensure that adults get more sleep could be to focus on "delaying the morning start time of work," or at least making it more flexible. 10 a.m. seems reasonable, offers a paper published online this week in the journal SLEEP.

After analyzing results from 124,517 American adults on their sleep and work habits, as recorded in the American Time Use Surveys from 2003 to 2011, lead study author Dr. Mathias Basner of the University of Pennsylvania Perelman School of Medicine and colleagues found an (unsurprising) association between earlier starting times for work or school and less time spent sleeping. "Results show that with every hour that work or educational training started later in the morning, sleep time increased by approximately 20 minutes," explains the press release. "Respondents slept an average of only 6 hours when starting work before or at 6 a.m. and 7:29 hours when starting work between 9 a.m. and 10 a.m."

9 Science-Backed Reasons Why You Should Go to Bed Early

,

Show of hands if you've ever stayed up way too late texting with friends, catching up on TV shows, or scrolling aimlessly through Pinterest or Reddit. Yep, plenty of us are guilty as charged -- and as a result, we end up feeling exhausted in the morning.

That most Americans are falling short on getting the recommended eight hours of sleep per night is nothing new. Clearly though, not everyone who fails to log enough shut eye actually has trouble sleeping. Plenty of us are just staying up too late or putting off bedtime in favor of other activities.

But over time, staying awake into the wee hours can come with a hefty cost. Here are nine surprising ways you can benefit from ditching, or at least minimizing, your night owl habit and following a consistently early bedtime schedule.

Why do we sleep?

Sleep is a normal, indeed essential part of our lives. But if you think about it, it is such an odd thing to do.

At the end of each day we become unconscious and paralyzed. Sleep made our ancestors vulnerable to attack from wild animals. So the potential risks of this process, which is universal among mammals and many other groups, must offer some sort of evolutionary advantage.

Research in this area was slow to take off. But recently there has been a series of intriguing results that are giving researchers a new insight into why we sleep and what happens when we do it.

Lost Sleep Leads to Loss of Brain Cells, Study Suggests

Sleep loss may be more serious than previously thought, causing a permanent loss of brain cells, research suggests.

In mice, prolonged lack of sleep led to 25% of certain brain cells dying, according to a study in The Journal of Neuroscience.

If the same is true in humans, it may be futile to try to catch up on missed sleep, say US scientists.

They think it may one day be possible to develop a drug to protect the brain from the side-effects of lost sleep.

How Dangerous is Sleep Deprivation, Really?

Everyone has a night here or there where sufficient sleep just doesn't happen. (Just ask anyone who's ever been to Vegas... or cared for a newborn.) But a lot of people miss out on getting significant shut-eye on a regular basis. In fact, about one in five American adults are sleep deprived.

The rumor: Sleep deprivation is harmful and can even be life-threatening

If you've ever come close to nodding off in the boardroom or behind the wheel, you know that the effects of sleep deprivation can range from embarrassing to downright terrifying. But are we really putting ourselves and others at risk, however inadvertently? And if we are sleep deprived, how do we fix it?

Here’s How Much Experts Think You Should Sleep Every Night

The National Sleep Foundation releases new recommendations

A national panel of sleep experts released new recommendations Monday that call for more hours of sleep for most young people.

The National Sleep Foundation, a nonprofit aimed at promoting healthy sleep and safety, says the amount of sleep a person needs is highly variable and that some people need more than others.
