How Your Sleep Position Can Impact Your Brain’s Waste Removal

How Your Sleep Position Can Impact Your Brain’s Waste Removal

If you aren’t sleeping in the right position, you could be increasing your odds of developing Alzheimer’s and other neurological disorders later in life.

This shocking conclusion was the result of a study performed by researchers at Stony Brook University when studying the effects of sleeping positions on the removal of brain waste.

Before understanding how the research was conducted and what the findings can mean for your health, it’s first important to understand what brain waste is and how improper removal can negatively impact your health.

Brain Waste and the Devastating Role It Can Play

With the amount of work that your brain performs on a daily basis, it’s no wonder that there will be an excess of waste that requires removal. While our brains don’t have the luxuries of custodians and garbage collectors, they do have their own mechanism for cleaning, and that’s the glymphatic system.

An extensive and organized system of pipes that works to clear brain waste just as the lympathic system clears waste in the rest of the body, this system for waste removal was unknown until 2012 when a group of researchers at the University of Rochester Medical Center made the discovery.

Simply put, brain waste is a combination of amyloids and tau proteins that have overstayed their welcome. The buildup of these improperly functioning proteins has been linked to Alzheimer’s and other neurological disorders and can have truly devastating effects.

The glymphatic system, which functions at all times during the day but which is most active during sleep, is what makes the removal of these proteins possible. Without this system in place, the non-soluble proteins would continue to buildup, leading to a plaque formation within our brain’s cells and wreaking havoc on our nervous system.

How the Research was Conducted

With the use of MRI (magnetic resonance imaging) and contrast dye, the researchers were able to locate the glympathic system and track the movement of its waste-clearing substance in the brains of anesthetized mice.

The mice were then manipulated into lying in one of three different positions — lateral (side), supine (on the back), and prone (on the stomach).

Researchers tracked the rates of waste removal based on these three positions, and the lateral position during sleep had an overwhelming advantage.

What this Discovery Means for You and How You Sleep

While this experiment was performed on mice and has yet to be done on human subjects, there are still some things that we can learn from the study’s conclusion.

The benefits of these findings were best explained by Dr. Nedergaard, a researcher from the University of Rochester and co-author of the study:

“Many types of dementia are linked to sleep disturbances, including difficulties in falling asleep. It is increasing[ly] acknowledged that these sleep disturbances may accelerate memory loss in Alzheimer’s disease. Our finding brings new insight into this topic by showing it is also important what position you sleep in.”

While there is still much research to be done, the conclusion of this study is clear:

“The analysis showed us consistently that glymphatic transport was most efficient in the [side] position when compared to the [back] or [stomach] positions,” said Dr. Benveniste.

The Future of Sleep and Brain Studies

While this new study may not be enough to convince diehard back and stomach sleepers to change their sleep positions, it does lead to future research questions and gives hope to those with a history of Alzheimer’s and similar disorders in their family.

The mysteries of the brain and nervous system are only now beginning to be solved — what this study and similar studies does is prove that each day we are one step closer to a fuller understanding of the human brain and how this knowledge can be used to fight the crippling and fatal effects of neurological diseases.

10 Real Reasons Why Breaking Bad Habits Is So Difficult

10 Real Reasons Why Breaking Bad Habits Is So Difficult

Bad habits expose us to suffering that is entirely avoidable. Unfortunately, breaking bad habits is difficult because they are 100% dependent on our mental and emotional state.

Anything we do that can prove harmful to us is a bad habit – drinking, drugs, smoking, procrastination, poor communication are all examples of bad habits. These habits have negative effects on our physical, mental, and emotional health.

Humans are hardwired to respond to stimuli and to expect a consequence of any action. This is how habits are acquired: the brain expects to be rewarded a certain way under certain circumstances. How you initially responded to certain stimuli is how your brain will always remind you to behave when the same stimuli are experienced.

If you visited the bar close to your office with colleagues every Friday, your brain will learn to send you a signal to stop there even when you are alone and eventually not just on Fridays. It will expect the reward of a drink after work every day, which can potentially lead to a drinking problem.

Kicking negative behavior patterns and steering clear of them requires a lot of willpower, and there are many reasons why breaking bad habits is so difficult.

1. Lack of Awareness or Acceptance

Breaking a bad habit is not possible if the person who has it is not aware that it is a bad one.

Many people will not realize that their communication skills are poor or that their procrastination is affecting them negatively, or even that the drink they had as a nightcap has now increased to three.

Awareness brings acceptance. Unless a person realizes on their own that a habit is bad, or someone manages to convince them of the same, there is very little chance of the habit being kicked.

2. No Motivation

Going through a divorce, not being able to cope with academic pressure, and falling into debt are instances that can bring a profound sense of failure with them. A person going through these times can fall into a cycle of negative thinking where the world is against them and nothing they can do will ever help, so they stop trying altogether.

This give-up attitude is a bad habit that just keeps coming around. Being in debt could make you feel like you are failing at maintaining your home, family, and life in general.

3. Underlying Psychological Conditions

Psychological conditions such as depression and ADD can make it difficult to start breaking bad habits.

A depressed person may find it difficult to summon the energy to cook a healthy meal, resulting in food being ordered in or consumption of packaged foods. This could lead to a habit that adversely affects health and is difficult to overcome.

A person with ADD may start to clean their house but get distracted soon after, leaving the task incomplete, eventually leading to a state where it is acceptable to live in a house that is untidy and dirty.

The fear of missing out (FOMO) is very real to some people. Obsessively checking their social media and news sources, they may believe that not knowing of something as soon as it is published can be catastrophic to their social standing.

4. Bad Habits Make Us Feel Good

One of the reasons it is difficult to break habits is that a lot of them make us feel good.[1]

We’ve all been there – the craving for a tub of ice cream after a breakup or a casual drag on a joint, never to be repeated until we miss how good it made us feel. We succumb to the craving for the pleasure felt while indulging in it, cementing it as a habit even while we are aware it isn’t good for us.

Overeating is a very common bad habit. Just another pack of chips, a couple of candies, a large soda… none of these are necessary for survival. We want them because they give us comfort. They’re familiar, they taste good, and we don’t even notice when we progress from just one extra slice of pizza to four.

5. Upward Comparisons

Comparisons are a bad habit that many of us have been exposed to since we were children. Parents might have compared us to siblings, teachers may have compared us to classmates, and bosses could compare us to past and present employees.

The people who have developed the bad habit of comparing themselves to others have been given incorrect yardsticks for measurement from the start.

These people will always find it difficult to break out of this bad habit because there will always be someone who has it better than they do: a better house, better car, better job, higher income and so on.

Research shows that in the age of social media, social comparisons are much easier and can ultimately harm self-esteem if scrolling becomes a bad habit[2].

6. No Alternative

This is a real and valid reason why breaking bad habits is difficult. These habits could fulfill a need that may not be met any other way.

Someone who has physical or psychological limitations, such as a disability or social anxiety, may find it hard to quit obsessive content consumption for better habits.

Alternately, a perfectly healthy person may be unable to quit smoking because alternates are just not working out.

Similarly, a person who bites their nails when anxious may be unable to relieve stress in any other socially accepted manner.

7. Stress

As mentioned above, anything that stresses us out can lead to adopting and cementing an unhealthy habit.

When a person is stressed about something, it is easy for bad habits to form because the mental resources required to fight them are not available[3].

We often see a person who had previously managed to kick a bad habit fall back into the old ways because they felt their stress couldn’t be managed any other way.

8. Sense of Failure

People looking to kick bad habits may feel a strong sense of failure because it’s just that difficult.

Dropping a bad habit usually means changes in lifestyle that people may be unwilling to make, or these changes might not be easy to make in spite of the will to make them.

Overeaters need to empty their house of unhealthy food, resist the urge to order in, and not pick up their standard grocery items from the store. Those who drink too much need to avoid the bars or even people who drink often.

If such people slip even once with a glass of wine, or a smoke, or a bag of chips, they tend to be excessively harsh on themselves and feel like failures.

9. The Need to Be All-New

People who are looking to break bad habits feel they need to re-create themselves in order to break themselves of their bad habits, while the truth is the complete opposite.

Advertising

These people actually need to go back to who they were before they developed the bad habit and try to create good habits from there.

10. Force of Habit

Humans are creatures of habit, and having familiar, comforting outcomes for daily triggers helps us maintain a sense of balance in our lives.

Consider people who are used to lighting up a cigarette every time they talk on the phone or eating junk food when watching TV. They will always associate a phone call with a puff on the cigarette and screen time with eating.

These habits, though bad, are a source of comfort to them, as is meeting with those people they indulge in these bad habits with.

Final Thoughts

These are the main reasons why breaking bad habits is difficult, but the good news is that the task is not impossible. Breaking habits takes time, and you’ll need to put long-term goals in place to replace a bad habit with a good one.

There are many compassionate, positive and self-loving techniques to kick bad habits. The internet is rich in information regarding bad habits, their effects and how to overcome them, while professional help is always available for those who feel they need it.
