Why Your Body Loves Sleep

You may think your body just shuts down when you sleep. However, your body goes through an amazing and complex process. As you go through the four stages of sleep each night, your body triggers processes that help you achieve that rested and healthy feeling the next morning.

Here’s a graphic from the Huffington Post that shows each stage of the sleep cycle and the effects that being in that stage have on your body.

Why Do Teens Nowadays Get Less Sleep Than Previous Generations?

Teens of this generation are generally getting less sleep than those of previous generations. What could be the reasoning behind this trend?

According to a study performed at Uni Research Health in Norway, the culprit could be the hours a day teens spend using electronic devices. The study was based on data gathered from 10,000 16- to 19-year-old boys and girls, who were asked about their daily quantity of screen time as well as their sleeping habits.

The findings were that those who used an electronic device for over four hours a day had a 49% higher risk of taking longer than an hour to fall asleep. Those who exceeded two hours of screen viewing per day were more likely to toss and turn before falling into a deep sleep. Teens who used multiple devices throughout the day were more likely to get less than five hours of sleep per night.

The reasoning behind this might be linked to the screen light, which may impact sleep hormone production. It could also be related to the social communication aspect, such as anticipating a response from a friend.

An easy way to fix this problem would be to treat electronic devices like any other stimulant (such as caffeine) and limit their use before bedtime and just in general. If the devices are not used while in bed, the body and mind won’t associate the bedroom with wakefulness, and could thus obtain better sleep.

The Science of the Brain During Sleep

Posted on

Our brains account for only 2% of our body’s mass, yet they use approximately a quarter of our entire energy supply. How does the brain receive and then expel the vital nutrients needed for all that energy? New research suggests that sleep has some amazing impacts on the brain. This Ted Talks video features Jeff Iliff, a neuroscientist, who explores the unique functions of the brain during sleep.

Sleep Deprivation and the Scary Effect It Can Have on Your Health

The importance of a good night’s sleep is often ignored as impending deadlines approach, or the countless tasks of the day require you to stay up later and later. But what is the damage that can be caused by not getting enough sleep? A sleep study was preformed last year, and the results were astonishing. The study showed that just sleeping less than six hours a night for a week caused changes to more than 700 genes! Here are some of the scary effects that not getting enough sleep can cause:

After one night of inadequate sleep you are…

More likely to eat more and be hungrier. Studies have shown that short-term sleep deprivation can result in a preference for high-calorie, high-carb foods and a greater likelihood of choosing unhealthy foods options.

You can be less focused and have memory problems. Being exhausted zaps your focus and renders you forgetful. According to Harvard University, sleep is thought to be involved in the process of memory consolidation, which means that not getting enough sleep can make it more difficult to learn and retain new things.

More likely to have an accident. Getting less than six hours of sleep can triple your risk of drowsy driving-related accidents, according to the National Sleep Foundation.

More likely to catch a cold. Proper rest is a major factor in a healthy immune system. A study preformed by Carnegie Mellon University found that sleeping fewer than seven hours a night tripled the risk of coming down with a cold.

You can’t look your best. Beauty sleep is a very real thing! Researchers have found that there are links between sleep deprivation and skin aging.

After an extended period of sleep deprivation you will experience an increased risk of stroke, obesity, some types of cancers, and heart disease, as well as other serious medical issues.

What Happens to Your Body When It’s Deprived of Sleep?

We all know how it feels to have a restless night. You feel irritable, dizzy, and unfocused throughout the next day. But when you are chronically sleep deprived, it can be seriously detrimental to your health. It can affect your body in many ways and in several different places.

 belly-2354_640

Body Fat- People who get only a few hours of sleep per night tend to have more body fat than those who get a full night’s rest. The lack of sleep/energy is compensated for the following day by consuming extra calories.

 Stomach

Stomach- Lack of sleep leads to a lower production of leptin, a hormone that regulates hunger and the storage of fat.

Motor Skills- After being awake for an extended period of time, you will notice a loss of precision in your motor skills. There is a delayed reaction from your brain in signaling a physical response.

 Blood_pressure_measurement_(2009)

Blood Pressure- Someone who sleeps very little on a regular basis will have much higher blood pressure than if they slept more. This is due to increased amounts of cortisol, a hormone that is released in response to stress.

Pancreas- People who are regularly deprived of sleep are twice as likely to develop diabetes, regardless of age or fitness level. The regulation of other hormone production is disrupted as well.

 Heart_(more_red)

Heart- Cardiovascular issues tend to develop in a large portion of people who have chronic sleep problems. The issues can range from weak or abnormal heartbeats to clogged arteries, or even cardiac arrest.

 Brain_picture

Brain- In a period of just a few days, you can damage and kill brain cells by not getting enough sleep at night. Without precious sleep, your brain cannot rid itself of proteins that cause plaque build-up. Over time, this plaque can cause dementia and Alzheimer’s disease.

Benefits of a Cool Sleeping Environment

Igloo_outside

Recent studies have found a correlation between cooler sleeping environments and metabolic health, relating to the volume of “brown fat” that is stored in a person’s body.

“Brown fat” is one of two types of fat found in mammals, along with the more common “white fat.” An abundance of brown fat is found in newborns and hibernating mammals, generating body heat for those who do not shiver.

Research has shown that this type of fat is metabolically active, unlike white fat. It takes sugar out of the bloodstream to burn calories and maintain the body’s core temperature.

It was previously thought that adults didn’t have brown fat stores in their bodies, but recent studies have detected small amounts stored in their necks and upper backs.

In a new study, five healthy male adults volunteered to sleep in climate-controlled rooms over the course of four months. Their blood-sugar and insulin levels were tracked throughout, along with their caloric expenditures. At the end of each month, they measured the amount of brown fat found in their bodies.

After four weeks of sleeping in cooler temperatures (66º F), the volume of brown fat had almost doubled, and improved insulin sensitivity was also seen.

By sleeping in a cooler room, adults could over time add to their stores of brown fat and lessen their risk for diabetes and other metabolic health problems.
