Sleep Deprivation and Memory Loss – A Undeniable Link

“Memory is all we are. Moments and feelings, captured in amber, strung on filaments of reason. Take a man’s memories and you take all of him.” Mark Lawrence, King of Thorns

Sleep Deprivation and Memory Loss

image of a woman who is forgetful.If we are the sum of our memories, the loss of them can be devastating. Memory loss is attributed to a number of conditions such as age, Alzheimer’s, injury, and illness, but the one cause that we have some control over is our sleep.

Studies show that sleep deprivation diminishes cognitive abilities because the brain minimizes clutter and maximizes memory when you’re sleeping. Without sleep, the brain just can’t function properly, and the longer you go without enough sleep the worse it gets. Exhaustion interferes with coordination, balance, and decision-making capacity.

How it Works

If you’re going to compare the central nervous system to anything, it would be a highway…a very busy highway. Every waking moment requires brain activity, and at the end of the day your brain is simply exhausted from that non-stop, hour after hour business of processing information. A major component of your brain activity is the synapses that serve as the lanes of communication that help retain all that information collected during the day.

New research that studies brain fatigue works around a theory called “synaptic homeostasis.” The theory’s basis is that sleep acts like a filter that weeds out and discards excess information and allows those busy synapses to relax. While some neurons rest, new communication lanes are created and long-term memories are stored. By the next morning the brain is refreshed and ready to start a new day. It makes sense–the only decent time for repairs to a highway or a nervous system is during a time when traffic is at its lowest.

Consequences

Lack of sleep means no rest for the old synapses and no new synapses to pick up and help carry the load. That impairs overall cognitive function, including concentration, the ability to learn new things, and short-term and long-term memory. Decision-making suffers and creativity is stifled. Even emotions are affected, which can cause mood swings and a short temper.

If you go long enough without sleep, you can start having hallucinations! For people who have narcolepsy or a condition called systemic lupus erythematosus, the potential for hallucinations from sleep deprivation doubles. People diagnosed with manic depression can end up with mania if they go sleepless too long. Additionally, sleep deprivation increases the risk of depression, suicidal thoughts, impulsive behavior and paranoia.

Let’s face it–without adequate sleep, your thought processes become muddled, your reasoning is reduced, and even your fine motor skills are mired because of inability to focus.

Making Memories while Avoiding Sleep Deprivation and Memory Loss

Memories come in different forms. Fact-based memories deal with things like remembering the names of former presidents and all the states. Episodic memories come from life events, such as a marriage proposal or when you attended the prom. Instructional or procedural memories are attached to things such as how to do math problems, play a guitar, or how to swim.

Memories develop from three steps that must occur:

  • When you learn or experience something new it is “acquisition.”
  • When a memory is stabilized in the brain it is “consolidation.”
  • Finally, when you’re able to access the memory later, it is “recall.”

Only when you’re awake can acquisition and recall occur. Studies indicate that consolidation only occurs during sleep, no matter which memory type it is. When you’re really tired and don’t get enough sleep, it’s difficult for your brain to absorb and recall anything new.

It isn’t known, yet, exactly how sleep augments memory, but it seems to revolve around the brain’s neocortex and hippocampus, which are where the brain stores long-term memories. It’s believed that when you’re asleep, the hippocampus repeats the day’s events for the neocortex, where the memories are reviewed and processed. That helps the memories to become long-term.

Another interesting area of research is the study of how the various stages of sleep affect the generation of certain memory types. Some memories are stabilized when you dream during rapid eye movement (REM) sleep. Other memories are secured during the period of slow-wave, very deep sleep. There are a good many questions still to be answered.

Save Your Memories!

The point is we know that sleep is an important factor in terms of both short-term and long-term memory. No matter what your age, those memories are a basic part of who you are. Children need memory to learn and progress. Adults need memory to function and have a good quality of life. Seniors need memory to hold close what life has been for them. You don’t want to squander those memories!

Strive for decent sleep by following steps recommended by the experts. We’ve covered these before, but let’s reiterate:

  • Set up a sleep schedule. Go to bed and get up at the same time, as that sets your body’s internal clock.
  • Be selective with food. If you’re hungry or stuffed when you go to bed, it will fool with your sleep, so be cautious with amounts and don’t eat too late. Limit beverages to avoid bathroom trips.
  • Develop a bedtime ritual. Pick what works for you—a book, a bath, or calming music. However, no electronic devices!
  • Make your room right for sleep. The best conditions are cool, dark, and quiet. A good mattress and pillow help.
  • Love your pets, but if they disrupt your sleep, make them stay in their own beds!

Remember, your memories are too important to ignore how sleep deprivation can affect them.

Your Mind/Body Connection – How Emotions Affect your Health

Have you ever noticed a physical reaction in your body when you experience intense emotions? Maybe you’re happy about seeing an old friend, or you passed an important test, or you discovered a five-dollar bill on the dresser that you thought you’d lost—whatever the reason, such experiences generate an elation that expresses as an actual sensation in your body. That’s why we refer to a rush of excitement, a flutter of joy.

The same thing happens when you’re sad, but the sensations aren’t as pleasant. You might feel tired and apathetic, and in the case of an extreme sadness—such as grief due to a loss or a natural disaster—you might even experience tightness in your chest or develop a stomach ache.

These physical reactions are real. It’s well known that certain emotions generate specific chemical reactions, and your body responds to the way you think, feel, and act. It’s a veritable “mind/body connection.”

Our Garland Chiropractic Clinic is invested in helping you find the mind/body balance you need to achieve good health. Let’s take a look at the issue.

First, an interesting history

More than a millennia ago, ancient Greeks, Romans, and East Indian physicians intuitively recognized that there was a link between illness and emotion. They embraced the theory that an imbalance in the four ‘humors’ (secretions) of blood, yellow bile, black bile, and phlegm caused diseases, and that the imbalance was caused by emotions.

This connection is so important we even derived some of our words from it. Melancholy comes from melan, the Latin word for “black,” and choler, the Latin word for “bitter bile.” A gloomy or embittered person is melancholic. And a phlegmatic person is considered languid and lethargic. We even developed the term “feeling sick” as a collective description that includes our sensory symptoms, such as nausea, fever, and exhaustion with how we feel psychologically, such as sad or apathetic.

The Mind/Body Connection and How it works

The effects your mind has on your physical body are profound. A different chemical is released each time we experience an emotion, whether it’s happiness or sadness, joy or depression. Each chemical literally creates a different environment inside our bodies. Considering our wide array of emotions, it’s no wonder our bodies suffer such a range of reactions!

Let’s think about negative reactions. Cortisol and adrenaline levels increase in your bloodstream when you’re stressed. They’re actually called stress hormones. These hormones work to redirect the blood supply from your deep organs into areas where it’s needed to allow your instinctive “flight-or-flight response,” preparing you to run as fast as you can. Your body believes that’s your best chance to escape whatever is causing the stress. It doesn’t matter if you’re stressed because you’re in real physical danger—like being stalked by a hungry tiger!—or if it’s caused by grief, sadness, or depression. Nature developed a very efficient and cool arrangement for us, utilizing our human emotions to initiate our survival instinct.

On the other end of the spectrum, when you feel happy, the body releases dopamine, oxytocin, or serotonin. Those hormones make you feel good.

  • Dopamine is a motivator, encouraging the action and persistence you need to meet your needs and goals.
  • Oxytocin is often referred as a “cuddle neurochemical” because it’s released by skin-to-skin contact.
  • Serotonin is the “confidence molecule,” coming into play when you feel important or significant. Low levels of serotonin can result in loneliness and depression.

It’s quite fascinating how the interplay of these hormones manifests in your physical responses. It’s been noted that love and happiness are “felt strongly all over our bodies, while depression causes us to lose sensation in every limb.” Pride creates a huge increase in the body’s internal activity, but it focuses in the upper body. Shame only burns your cheeks, while fear is felt in your chest and disgust—like phlegm—fills your throat.

Physical health impacts of the Mind/Body Connection

What happens if you think negatively all the time?

  • Long term stress can cause an ulcer.
  • Anxiety can increase the heartrate and blood pressure, cause shortness of breath, and could result in chest pains.
  • Depression causes tiredness and fatigue.
  • The immune system can be weakened.
  • Physical health is impacted when stress, anxiety, and depression interfere with a person taking care of themselves.

Additional issues may include: poor appetite, dry mouth, back pain, constipation or diarrhea, insomnia, sweating, stiff neck, headaches, weight loss or gain, and just general aches and pains.

Controlling your own health

If negative thoughts can hurt you, positive thoughts can help you.

Optimism alone seems to reduce cortisol levels and inflammation that’s caused by stress. It might well decrease a person’s potential to be impacted by diseases because it suppresses activity of the sympathetic nervous system while stimulating the “rest-and-digest” response of the parasympathetic nervous system. Positive people can lower their cardiovascular responses to stress.

Good emotional health means being aware of your own thoughts, feelings, and reactions. There are always stress and problems in life and you have to learn to deal with them in a manner that helps you stay healthy.

Here are some helpful tips for taking charge of your mind/body connection:

  • Don’t keep your feelings inside if it makes you feel worse. Express yourself, and do it in a positive way. Tell people how you feel. Turn to a doctor, counselor or pastor if you need emotional support.
  • Keep your life balanced. Try not to obsess about the things in your daily life that bother you. You have to deal with them, but bring in positive feelings and activities to lessen that burden. Focus on a positive outlook.
  • Learn resilience so you can cope. Find social support, accept change, and keep the issues in perspective.
  • Work to calm yourself mentally and physically. Try yoga, meditation, music, a good book or a movie you love. If an intimate group of friends helps, invite them over for a talk fest!
  • It’s important to take care of yourself. If you’re emotionally healthy, work on body health. If your body is healthy, work on your emotional strength. Eat right, sleep enough, and exercise to throw off tension. Avoid alcohol and drugs.
  • Contact Texas Spine & Wellness and let our trained professionals set up a program that will help you reach an optimal level of physical health.

Remember, the power to take on and overcome what life throws at you lies within yourself. Remember, too, these words said by Hippocrates:

“If someone wishes for good health, one must first ask oneself if he is ready to do away with the reasons for his illness. Only then is it possible to help him.”

Sleep Deprivation and Heart Health – A Serious Link

Our busy lifestyles often leave us little time for rest, which has resulted in a major change in sleep patterns. Now people sleep an hour to two hours less than they did just 50 years ago. While some people might consider this great for productivity, it’s not a good situation for our health. Recent research indicates there’s a link between those shorter hours of sleep and an increased potential to develop heart disease.

Man with sleep deprivationIn the United States, heart disease is reported to be the leading cause of death and disability, with strokes being the number 4 cause. A major threat factor in both cases is high blood pressure.

The lack of sleep—or prolonged sleep—isn’t necessarily the cause of heart disease, but it definitely affects the heart disease risk factors in terms of arrhythmia, stroke and heart failure.

These are the kinds of statistics that research has revealed about sleep deprivation:

  • A 48% increase in the risk of getting or dying from coronary heart disease (CHD);
  • A 15% risk increase in developing or dying from stroke;
  • Interestingly, there is also a 38% risk increase of CHD in people who sleep too much, such as nine or more hours a night!

Just like the rest of your body, your heart needs rest. It never stops beating, so resting that reduces the heart rate and blood pressure is essential to its health.

Sleep Regulates Your Health!

While you sleep, your body regulates insulin levels, hormone levels,including stress hormones, and blood pressure. When you don’t get enough sleep it throws all of those things out of sync.

It’s those hormone levels, in particular, which affect your appetite and energy. When those decrease because you’re tired, you have a greater chance for weight gain, the development of insulin resistance, and metabolic syndrome. Metabolic syndrome is a collection of physiological and biochemical abnormalities associated with initiating cardiovascular disease. This is because it triggers inflammation, and studies have shown that inflammation causes high blood pressure. This explains why the risk of stroke or heart attack shoots up when you don’t get enough sleep.

If you already have a heart problem, even short-term sleep deficit is shown to be harmful. The effect of daylight saving time, which strips away that extra hour of additional sleep in spring, is known to increase the risk for heart attacks by a surprising 4%!

The depth of your sleep is also important. Along with shorter sleep, shallow sleep can result in hypertension. Without long periods of deep rest, the important chemicals needed to keep the heart rate and blood pressure lowered, aren’t activated. So, the longer you sleep deeply, the better rested you are and the better your heart feels.

Sleep Apnea

Not everyone suffers from sleep apnea, but the manner in which the condition affects heart health is one of the reasons the “sleep and hearth health” link has been identified.

Sleep apnea causes snoring and gasping for breath while a person sleeps. That condition results in the heart rate increasing, a rise in blood pressure, and frequently disrupted sleep. All of the bodily functions that normally slow down at night are forced to continue operating at a higher rate of activity. Over time, the higher blood pressure carries over into the day. Some researchers believe at least one-third of identified cases of high blood pressure among adults are due to sleep apnea. As mentioned above, high blood pressure during the day increases the chance for cardiovascular issues.

Sleep Deprivation Catches Up with You

No one intentionally decides they just aren’t going to get enough sleep. Even night owls require down time to rejuvenate, and people who thrive on activity and long hours are forced to sleep whether they want to or not. But in many cases it’s simply difficult to fall asleep, or to stay asleep when you finally manage to drift off. That can be due to external factors, such as work, children, emergencies, a middle-of-the-night phone call, a restless partner or pet, an uncomfortable bed, or to internal factors such as worry, anxiety, bad dreams, depression, excitement, or sundry other mental intrusions.

A lack of sleep causes “sleep debt,” which isn’t unlike being overdrawn at your bank. It catches up with your body, and your body won’t let you go without repaying the debt. People don’t adapt to getting less sleep. Eventually all of your functions are impaired and you have to react.

Here are a few tips to help with sleep issues:

  • Get a little exercise during the day
  • Keep regular bedtime hours
  • Refrain from late night snacks; especially caffeine and alcohol
  • Keep your bedroom dark and quiet
  • Limit your use electronics such as a tablet or a cell phone

If you need extra help, a cup of soothing herbal tea, accompanied by a a small dose (1 to 3 mg.) of melatonin may help you fall asleep.

There is an Irish proverb that says “A good laugh and good sleep are the best cures in the doctor’s book.” An excellent perspective to embrace in order to keep your heart healthy!
