Scientists Say This Is Probably the Real Reason Why People Have Addiction

Scientists Say This Is Probably the Real Reason Why People Have Addiction

$700 billion a year. Yes, that is the whopping bill the USA has to fork out because of addiction every year. This is the cost in terms of health care, lost working days to the nation for addiction to drugs, alcohol and smoking, just to name a few. What is the solution? The first step would be to understand what really causes addiction and what is the latest scientific explanation for this. Secondly, we could look at the role of decriminalization of drugs and how this may lead to a safer and healthier society.

Why do people get addicted?

The problem arises when the pleasurable activities such as sex, food, gambling or use of drugs and alcohol becomes compulsive and starts to interfere with work, health and relationships. It is interesting to note that in the early 1930s addiction to alcohol and other substances was seen as having a lack of willpower or character. But now scientists are investigating the real cause of addiction and their results are surprising, to say the least.

One view is that people become addicted to a substance or behavior because it gives them some comfort or relief from some sort of psychological stress. Alcohol can give a sense of euphoria in the short term especially when anxiety and depression are present. The long term effects are damaging to health. Even more troubling is that the addiction prevents the sufferer from looking for the cause and in seeking treatment.

Researchers have homed in on the lateral habenula region of the brain which governs whether we see something as being rewarding or having too many negative consequences. Experiments with rats seem to indicate that is one of the areas of the brain affected by alcohol, but more studies need to be done.

More rat experiments in the 1980s got a lot of publicity from ads which were run by the Partnership for a Drug-Free America (PDFA). Here, one lone rat was put into a cage with two bottles, one containing water and the other a mix of water and cocaine. The rat became addicted to the drugged water, kept on coming back for more and then died. The advert then warns:

“Only one drug is so addictive, nine out of ten laboratory rats will use it. And use it. And use it. Until dead. It’s called cocaine. And it can do the same thing to you.”

The message was clear that there were strong chemical agents which were causing the craving and addiction. You can see some of the PDFA ads which were broadcast in 1987 here. Chemical agents could not explain an addiction to gambling, however.

The view from Rat Park

But Professor Bruce Alexander of Simon Fraser University and author of The Globalisation of Addiction: A study in poverty of the spirit, was not so sure. He started experiments with the famous Rat Park.

He put some rats in solitary confinement with a water bottle and another with a mix of drugs. Then for another group of rats, he created Rat Park. This was an ideal environment for them where they had exercise wheels, balls to play with and great food. The researchers noticed that the rats in solitary were addicted to the cocaine mix while the rats in Rat Park hardly touched the stuff and were extremely happy and contented. None of them died.

Alexander’s crucial question was whether humans might be similar to the rats. Could one’s environment and psychological state really determine whether a person would become addicted or not? Unfortunately, the impact of the study on the theory of addiction was almost nil and Rat Park was closed.

The questions that need answers.

People on medication do not become addicted whereas the typical street addict is hooked for life, unless he or she seeks rehab. Could it really be just due to the fact humans need to bond and receive affection from a loving and caring environment? The figures from the return of the Vietnam War veterans would seem to support this theory.

It is a well known fact that about 20% of these soldiers were heroin or cocaine addicts. But after they returned home, a whopping 95% of these addicted soldiers simply gave up the habit. Only a tiny number actually needed rehab. Like the rats in the cage, they had no need of any drugs once they were back in a safer and more caring environment. We cannot imagine a more terrifying cage than war!

Is decriminalization the answer?

Look at what Portugal did. In the year 2000, the government decided to decriminalize drug use. They wanted to treat drug addicts, rather than punish them. Now, more than 10 years later, the drug use ratio has fallen by 50%. Of course, more innovative treatment methods and reducing some of the risk factors played a part in this turnaround.

This may well be the way forward. The vast sums of money spent in chasing, arresting, trying and imprisoning drug users was used in helping drug users to reconnect with society again and to help give them a purpose in life. In other words, they have helped them get out of their solitary confinement cage.

Why You’re Feeling Tired All the Time (and What to Do About It)

Why You’re Feeling Tired All the Time (and What to Do About It)

If you find that you’re feeling tired all the time, it’s important to understand that it’s a common problem for many. With all of the demands of daily life, being tired seems to be the new baseline. In fact, two-fifths of Americans are tired most of the week.[1]

If you’re tired of feeling exhausted, then I’ve got some great news for you. New research is helping us gain critical insights into the underlying causes of feeling tired all the time.

In this article, we’ll discuss the latest reasons why you’re so tired and practical steps you can take to finally get to the bottom of your fatigue and feel rested.

What Happens When You’re Too Tired

If you sleep just two hours less than the normal eight hours, you could be as impaired as someone who has consumed up to three beers.[2] And you’ve probably experienced the impact yourself.

Here are some common examples of what happens when you’re feeling tired:[3]

  • Trouble focusing because memory and learning functions may be impaired.
  • Experience mood swings and an inability to differentiate between what’s important and what’s not.
  • Dark circles under your eyes and/or your skin make look dull and lackluster in the short term and over time your skin may get wrinkles and show signs of aging because your body didn’t have time to remove toxins during sleep.
  • Finding it more difficult to exercise.
  • Immune system may weaken, causing you to pick up infections more easily.
  • Overeating because not getting enough sleep activates the body’s endocannabinoids, even when you’re not hungry.
  • Metabolism slows down, so what you eat is more likely to be stored as belly fat.

Why Are You Feeling Tired All the Time?

Leading experts are starting to recognize that there are three primary reasons people feel tired on a regular basis: sleep deprivation, fatigue, and Chronic Fatigue Syndrome (CFS).

Here’s a quick overview of each common cause of fatigue and feeling tired all of the time:

  1. Tiredness occurs from sleep deprivation when you don’t get high-quality sleep consistently. It typically can be solved by changing your routine and getting enough deep, restorative sleep.
  2. Fatigue occurs from prolonged sleeplessness, which could be triggered by numerous health problems, such as mental health issues, long-term illness, fibromyalgia, obesity, sleep apnea, or stress. It typically can be improved by changing your lifestyle and using sleep aids or treatments, if recommended by your physician.
  3. Chronic Fatigue Syndrome (CFS) is a medical condition also known as Myalgic Encephalomyelitis that occurs from persistent exhaustion that doesn’t go away with sleep.

The exact cause of CFS is not known, but it may be due to problems with the immune system, a bacterial infection, a hormone imbalance, or emotional trauma. It typically involves working with a doctor to rule out other illnesses before diagnosing and treating CFS.[4]

Always consult a physician to get a personal diagnosis about why you are feeling tired, especially if it is a severe condition.

Feeling Tired Vs Being Fatigued

If lack of quality sleep doesn’t seem to be the root cause for you, then it’s time to explore fatigue as the reason you are frequently feeling tired.

Until recently, tiredness and fatigue were thought to be interchangeable. Leading experts now realize that tiredness and fatigue are different.

Tiredness is primarily about lack of sleep. However, fatigue is a perceived feeling of being tired that is much more likely to occur in people who have depression, anxiety, or emotional stress and/or are overweight and physically inactive[5].

Symptoms of fatigue include:

  • Difficulty concentrating
  • Low stamina
  • Difficulty sleeping
  • Anxiety
  • Low motivation

These symptoms may sound similar to those of tiredness, but they usually last longer and are more intense.

Unfortunately, there is no definitive reason why fatigue occurs because it can be a symptom of an emotional or physical illness. However, there are still a number of steps you can take to reduce difficult symptoms by making a few simple lifestyle changes.

How Much Sleep Is Enough?

The number one reason you may feel tired is because of sleep deprivation, which means you are not getting enough high-quality sleep.

Research suggests that most adults need 7 to 9 hours of high-quality, uninterrupted sleep per night[6]. If you’re sleep deprived, the amount of sleep you need increases.

Get the right amount of sleep to stop feeling tired.

    The key to quality sleep is being able to get long, uninterrupted sleep cycles throughout the night. It typically takes 90 minutes for you to reach a state of deep REM sleep where your body’s healing crew goes to work.

    Ideally, you want to get at least 3 to 4 deep REM sleep cycles in per night. That’s why it’s so important to stay asleep for 7 or more hours.

    Research also shows that people who think they can get by on less sleep don’t perform as well as people who get at least seven hours of sleep a night[7]

    If you are not getting 7 hours of high-quality sleep regularly, then sleep deprivation is the most likely reason you feel tired all the time. That is actually good news because sleep deprivation is much simpler and easier to address than the other root causes.

    It’s also a good idea to rule out sleep deprivation as the reason why you are tired before moving on to the other possibilities, such as fatigue or Chronic Fatigue Syndrome, which may require a doctor for diagnosis and treatment.

    4 Simple Changes to Reduce Fatigue

    Personally, I’m a big believer in upgrading your lifestyle to uplift your life. I overcame chronic stress and exhaustion by making these four changes to my lifestyle:

    1. Eating healthy, home-cooked meals versus microwaving processed foods or eating out
    2. Exercising regularly
    3. Using stressbusters
    4. Creating a bedtime routine to sleep better

    After I made the 4 simple changes in my lifestyle, I no longer felt exhausted all of the time.

    I was so excited that I wanted to help others replace stress and exhaustion with rest and well-being, too. That’s why I became a Certified Holistic Wellness Coach through the Dr. Sears Wellness Institute.

    Interestingly enough, I discovered that Dr. Sears recommends a somewhat similar L.E.A.N. lifestyle:

    • L is for Lifestyle and means living healthy, including getting enough sleep.
    • E is for Exercise and means getting at least 20 minutes of physical activity a day, ideally for six days a week.
    • A is for Attitude and means thinking positive and reducing stress whenever possible.
    • N is for Nutrition and means emphasizing a right-fat diet, not a low-fat diet.

    The L.E.A.N. lifestyle is a scientifically-proven way to reduce fatigue, get to the optimal weight, and to achieve overall wellness.[8]

    Living Healthy

    Getting enough high-quality sleep every day is the surefire way to help you feel less fatigued, more rested, and better overall.

    In fact, if you aren’t getting enough sleep, your body isn’t getting the time it needs to repair itself; meaning that if you are suffering from an illness, it’s far more likely to linger. In fact, long-term sleep deprivation has been linked to an increase in Alzheimer’s later in life[9].

    As unlikely as it sounds, though, fatigue can sometimes make it difficult to sleep. That’s why I’d recommend taking a look at your bedtime routine before you go to bed and optimize it based on sleep best practices.

    Here are 3 quick and easy tips for creating a pro-sleep bedtime routine:

    1. Unplug

    Many of us try to unwind by watching TV or doing something on an iPhone or tablet. However, tech can affect your melatonin production due to the blue light that they emit, fooling your body into thinking it’s still daytime. This won’t help you stop feeling tired all the time.

    Try to turn off all tech one hour before bed and create a tech-free zone in your bedroom.

    2. Unwind

    Use the time before bed to do something you find relaxing such as reading a book, listening to soothing music, meditating, or taking an Epsom salt bath.

    3. Get Comfortable

    Ensure your bed is comfortable and your room is set up for sleep.

    Make sure you room is cool. 60-68 degrees is the ideal temperature for most people to sleep. Also, it’s ideal if your bedroom is dark and there is no noise.

    Finally, make sure everything is handled (e.g., laying out tomorrow’s clothes) before you get into your nice, comfy bed. If your mind is still active, write a to-do list to help you fall asleep faster.[10]

    Exercise

    Many people know that exercise is good for them, but they just can’t figure out how to fit it into their busy schedules.

    That’s what happened in my case, but when my chronic stress and exhaustion turned into systemic inflammation (which can lead to major diseases like Alzheimer’s), I realized it was time to change my sedentary lifestyle.

    I decided to start swimming because it was something I had always loved to do. Find an exercise you love and stick to it to stop feeling tired all the time. Ideally, get a combination of endurance training, strength training, and flexibility training during your daily 20-minute workout.

    If you haven’t exercised in a while and have a lot of stress in your life, you may want to give yoga a try as it will increase your flexibility and lower your stress.

    Attitude

    Stress may be a major reason why you aren’t feeling well all of the time. At least that was the case with me.

    When I worked 70 hours per week as a High-Tech Executive, I felt chronically stressed and exhausted, but there was one thing that always worked to help me feel calmer and less fatigued: Breathing.

    But not just any old breathing. It was a special form of deep Yogic breathing called the “Long-Exhale Breathing” or “4-7-8 breathing” (or “Pranayama” in Sanskrit).

    Here’s how you do Long-Exhale Breathing:

    Advertising

    1. Sit in a comfortable position with your spine straight and your hand on your tummy.
    2. Breathe in deeply and slowly from your diaphragm with your mouth closed while you count to 4 (ideally until your stomach feels full of air).
    3. Hold your breath while you mentally count to 7 and enjoy the stillness.
    4. Breathe out through your mouth with a “ha” sound while you count to 8 (or until your stomach has no more air in it).
    5. Pause after you finish your exhale while you notice the sense of wholeness and relaxation from completing one conscious, deep breath.
    6. Repeat 3 times, ensuring your exhale is longer than your inhale so you relax your nervous system.

    This type of “long-exhale breathing” is scientifically proven to reduce stress.

    When your exhale is twice as long as your inhale, it soothes your parasympathetic nervous system, which regulates the relaxation response.[11]

    Nutrition

    Diet is vital for beating fatigue if you’re feeling tired all the time – after all, food is your main source of energy.

    If your diet is poor, then it implies you’re not getting the nutrients you need to sustain healthy energy levels, which may lead to daytime sleepiness.

    Eating a diet for fatigue doesn’t need to be complicated or time-consuming though. For most people, it’s just a case of swapping a few unhealthy foods for a few healthier ones, like switching from low-fiber, processed foods to whole, high-fiber foods.

    Here’re 9 simple diet swaps you can make today:

    1. Replace your morning coffee with Matcha green tea and drink only herbal tea within six hours of bedtime.
    2. Add a healthy fat or protein to any carb you eat, especially if you eat before bed.
    3. Fill up with fiber, especially green leafy vegetables.
    4. Replace refined, processed, low-fiber pastas and grains with zucchini noodles and whole grains such as buckwheat, quinoa, sorghum, oats, amaranth, millet, teff, brown rice, and corn.
    5. Swap natural sweeteners for refined sugars, and try to ensure you don’t get more than 25g of sugar a day if you are a woman and 30g of sugar a day if you are a man.
    6. Replace ice cream with low-sugar alternatives.
    7. Swap omega-6, partially-hydrogenated oils such as corn, palm, sunflower, safflower, cotton, canola and soybean oil for omega-3 oils such as flax, olive, and nut oils.
    8. Replace high-sugar yoghurts with low-sugar, dairy-free yoghurts.
    9. Swap your sugar-laden soda for sparkling water with a splash of low-sugar juice.

    Also, ensure your diet is giving you enough of the daily essential vitamins and minerals. Most of us don’t get enough Vitamin D, Vitamin B-12, Calcium, Iron, and Magnesium. If you are low on any of the above vitamins and minerals, you may experience fatigue and low energy.

    That’s why it’s always worth having your doctor check your levels. If you find any of them are low, then try to eat foods rich in them.

    Alternatively, you might consider a high-quality multivitamin or specific supplement.

    The Bottom Line

    If you are tired of feeling tired all the time, then there is tremendous hope.

    If you are tired because you are not getting enough high-quality sleep, then the best remedy is a bedtime routine based on sleep best practices. If you are tired because you have stress and fatigue, then the best remedy are four simple lifestyle changes discussed above.

    Overall, adopting a healthier lifestyle is the ideal remedy for feeling more rested and energized.
