How Does Sleep Deprivation Affect Your Brain? with Dr. Shane Creado

Given that a single sleepless night can make you irritable and moody the following day, it’s not surprising that chronic sleep debt may lead to long-term mood disorders like clinical depression and generalised anxiety disorder in adults.

When people with anxiety or depression were surveyed to calculate their sleeping habits, it turned out that most of them slept for less than 6 hours a night.

Worsens Mood And Behavior

Kids can get moody or silly when theyre tired. They may have less self-control than they usually do. And they might get frustrated or lose their temper more easily. Having a shorter fuse may cause them to give up on homework or tests. And if they lose their temper, they might end up in the principals office instead of the classroom.

The Immune System Doesn’t Work As Well When You’re Tired

You know those great things your immune system does when you get a wound but don’t immediately get an infection, or you come near a sick person but don’t get ill yourself? Prolonged sleep deprivation and even one night of sleeplessness can impede your body’s natural defenses against infection. Sleep deprivation also seems to make newly received vaccines less effective.

A Growing Body Of Evidence Links Bad Sleep With Signs Of Alzheimer’s In The Brain

Several studies have found that sleep helps cleanse the brain of the beta-amyloid protein that can build up while you are awake. That protein is strongly associated with Alzheimer’s disease. Researchers say that a lack of sleep can lead to a vicious cycle, since the more beta-amyloid protein there is in the brain, the harder it is to get to a cleansing deep-sleep state. People with more disrupted sleep schedules tend to have more beta-amyloid protein built up.

The story of Tripp has an unhappy ending. Shortly after his wakeathon his marriage broke down, and he eventually lost his job and career in radio. In 1964 his record was broken by Randy Gardner, a high school student from San Diego, who managed to remain awake for 264 hours.

Tripps later troubles however are unlikely to be connected to his sleep deprivation as Gardner and others who later tried to beat the record did not report similar long-term detrimental effects. Nonetheless, there are lessons to be learned from Tripps experience and from the latest discoveries in sleep science.

Many people arent getting enough sleep as people sacrifice rest time to work, especially on devices which emit blue light. This light makes falling asleep more difficult, further eroding the quantity and quality of sleep.

Are The Impacts Of Poor Sleep On Thinking The Same For Everyone

Not everyone is affected by poor sleep in the same way. Studies have found that some individuals may be more inclined to have cognitive impairment from sleep deprivation, and this may even have a genetic component.

Research has generally discovered that adults are better at overcoming the effects of sleep deprivation than younger people. Teens are considered to be especially high-risk for detrimental effects of poor sleep on thinking, decision-making, and academic performance because of the ongoing brain development occurring during that age.

Some studies have also found that women are more adept at coping with the effects of sleep deprivation than men, although it is not yet clear if this is related to biological factors, social and cultural influences, or a combination of both.

National Geographic Magazine has reported that the demands of work, social activities, and the availability of 24-hour home entertainment and Internet access have caused people to sleep less now than in premodern times.USA Today reported in 2007 that most adults in the USA get about an hour less than the average sleep time 40 years ago.

Other researchers have questioned these claims. A 2004 editorial in the journal Sleep stated that according to the available data, the average number of hours of sleep in a 24-hour period has not changed significantly in recent decades among adults. Furthermore, the editorial suggests that there is a range of normal sleep time required by healthy adults, and many indicators used to suggest chronic sleepiness among the population as a whole do not stand up to scientific scrutiny.

A comparison of data collected from the Bureau of Labor Statistics‘ American Time Use Survey from 19651985 and 19982001 has been used to show that the median amount of sleep, napping, and resting done by the average adult American has changed by less than 0.7%, from a median of 482 minutes per day from 1965 through 1985, to 479 minutes per day from 1998 through 2001.

Sleep loss can put you at risk for heart disease, high blood pressure, diabetes, obesity and several other chronic medical conditions. A greater degree of sleep deprivation is possibly associated with greater adverse effects on health. ;For example, sleep loss leads to an increase in ghrelin levels, a hormone responsible for stimulating appetite.

There is also a relationship between shorter sleep time and impaired glucose tolerance, a key issue in diabetes. Large population studies indicate increased risk of heart attacks and strokes related to sleep loss. Poor sleep is associated with lower life expectancy.;

That number might not sound large, but its a significant change statistically speaking, Ochab says. And it could have meaningful real-world consequences, such as if youre in a high stakes job like one that requires you to operate heavy machinery, perform surgery, or direct air traffic, he explains. Any drop in performance might be significant in your real life.

The actigraphs also revealed that chronic sleep deprivation had lasting effects. At baseline, study participants sat still or took on physical activity for prolonged periods . But during the sleep deprivation phase of the study, their wrist sensors indicated participants were moving every 5 to 10 minutes. During the recovery phase, participants rest and activity patterns were closer to what they were at the start of the study, but still more disrupted on average.

Clearly sleep deprivation caused participants to be agitated, Ochab. The actigraph results dont record what activity was being done, but the patterns suggest that when sleep deprived, the study participants were less able to sit still to work for long periods of time or do an activity without stopping to rest every 5 to 10 minutes.

And finally, on the basis of EEG monitoring, electrical activity in study participants patterns of brain activity was also still disrupted after seven days of recovering from a lack of sleep.

Why Dont People Value Sleep

Most people who donât get enough sleep donât recognize the toll that it takes on their cognitive and mental health.

Many people think of sleep simply as a luxury — a little downtime. They know they feel better when they get a good nightâs sleep and worse when they donât. But sleep actually improves learning, memory, and insight.

âYouâre putting energy in the bank when you go to sleep,â says Barry Krakow, MD, medical director of Maimonides Sleep Arts and Sciences, Ltd. in Albuquerque, N.M., and author of Sound Sleep, Sound Mind: 7 Keys to Sleeping Through the Night. âOn a cellular level, the body is literally repairing and restoring itself. Without it, you canât do what you want — physically or mentally.â

And catching up on your sleep is a bigger job than many people realize. If you get less than six hours of sleep a night for a week, for example, youâll rack up a full nightâs sleep debt — too much to make up for with a few hours extra sleep on the weekend.

Study Blames Mental Lapses On Sleep

A new UCLA-led study is the first to reveal how sleep deprivation disrupts brain cells’ ability to communicate with each other. Itzhak Fried, MD, PhD ’81, professor of neurosurgery, and his colleagues believe that disruption leads to temporary mental lapses that affect memory and visual perception.

We discovered that starving the body of sleep also robs neurons of the ability to function properly, Dr. Fried says. This leads to cognitive lapses in how we perceive and react to the world around us.

The international team of scientists studied 12 people who were preparing to undergo surgery for epilepsy at UCLA. The patients had electrodes implanted in their brains in order to pinpoint the origin of their seizures prior to surgery. Because lack of sleep can provoke seizures, patients stay awake all night to speed the onset of an epileptic episode and shorten their hospital stay.

Researchers asked each participant to categorize a variety of images as quickly as possible. The electrodes recorded the firing of a total of nearly 1,500 brain cells as the patients responded, and the scientists paid particular attention to neurons in the temporal lobe, which regulates visual perception and memory. Performing the task grew more challenging as the patients grew sleepier. As the patients slowed down, so did their brain cells.

Weight Gain & Obesity

The effects of continual sleep problems include rapid weight gain. A lack of sleep is related to higher amounts of cortisol, a stress hormone; the resulting anxiety, stress and frustration often contribute to emotional eating and poor nutritional habits. Another hormone, called ghrelin, is produced in the stomach and has been associated with sleep long-term deprivation; an excess of ghrelin can actually make people feel more hungry.

Over time, sleep deprivation negatively impacts the bodys metabolism and eating habits. Tiredness often leads to unhealthy cravings and overindulgence, accompanied by a decrease in stamina and physical activity. Research has shown that people who feel unrested are more likely to choose foods that are rich in carbohydrates and sugar.

Mathematics tells us that a decrease in exercise, combined with an increase in the amount eaten plus an increase in the caloric value of the food ingested, equals weight gain. Obesity is a known risk factor for insomniacs.

What Happens To The Brain During Sleep

During a typical night of sleep, an individual goes through four to six sleep cycles that range from 70 to 120 minutes each. Both the brain and body experience distinct changes during these cycles that correspond to individual stages of sleep.

During NREM stages, brain activity slows overall, but there remain pulses of specific types of brain waves. This pattern of brain waves is most pronounced in stage 3 NREM sleep, which is also known as slow-wave sleep or deep sleep.

In contrast, REM sleep is marked by a sizable uptick in brain activity. In many ways, the brains activity during REM sleep is similar to when youre awake. Not surprisingly, REM sleep is known for more vivid and involved dreaming.

Its normal to cycle through both NREM and REM stages, with REM sleep being more concentrated in the second half of the night. During each part of this process, different chemicals in the brain become activated or deactivated to coordinate rest and recovery.

Experts still arent exactly certain why sleep proceeds in this pattern, but it is believed that it facilitates mental recovery, which can unlock cognitive benefits related to attention, thinking, and memory.
