Many people hear “yoga”, and think Zen gardens, meditation, and free spirits. But you may be surprised to find that one recent study showed that those who incorporated yoga into their life had improved stress levels and lower blood pressure. Yoga was ultimately developed to combine controlled breathing and poses to achieve physical, mental, and spiritual strength and unity. In fact, Michelle Obama even attributes her sleek physique to frequent yoga sessions. There are multiple types of yoga, but Hatha Yoga is the most commonly practiced type in the United States.

Here are some surprising health benefits of practicing yoga that you may have never known!

Relief of Back Pain: More than 60 million Americans suffer from chronic back pain. Yoga is one of the best exercises to help alleviate pain. This is due to the increase in core stability (abdominal muscles) and the reduction of pressure across the lower back and surrounding muscles. Yoga also helps to release endorphins throughout the body that can calm inflammation. Practicing yoga for just two sessions a week may reduce or even eliminate back pain. Many individuals also report an increase in pain tolerance after attending sessions for only three weeks.

Heart Healthy: Further research also demonstrates that even one yoga session can produce a calming effect on the body, and individuals in one study showed reduction in their systolic blood pressure after only 12 weeks of two yoga sessions per week. Additionally, incorporating yoga into a cardiac rehabilitation program after a heart attack or bypass surgery has also shown promise in maintaining lower levels of stress and healthy blood pressure levels.

Increased Flexibility: You may be thinking, “No Duh”, on this one, but the benefits may be surprising. Practicing poses like downward dog, and tree pose can improve balance and flexibility. This can directly strengthen and protect your larger joints (knees, hips, back, neck) from injury and reduce inflammation in the smaller joints (fingers and ankles). This can also help reduce falls in the elderly, and ultimately avoid fractures in this age group.

Mood Booster: In addition to mental clarity and relaxation, yoga has been shown to improve depression, anxiety, and chronic stress. A small German study reviewed in the Harvard Mental Health Letter demonstrated that at the end of a three-month period, women perceived less stress, depression, anxiety, and fatigue. A few yoga classes could leave you happier and less stressed. Increased happiness alone is reason enough to give it a try!

As with any new exercise, always consult your physician before you begin. This is to ensure your body can safely complete the activity. I also recommend you attend a beginner class or view a video with some common poses. This will make you feel more confident during your first class and ensure you obtain the most benefit.

I’ve been teaching a stress less/relaxation class for years and below is one the handouts that participants report is most helpful.:0854f-feelings-54

Change the situation: Avoid – Alter. Change your reaction: Adapt – Accept

1. Avoid unnecessary stress

Not all stress can be avoided, and it’s not healthy to avoid a situation that needs to be addressed.

Learn how to say “no” – Know your limits and stick to them.

Avoid people who stress you out –Limit the amount of time you spend with people that cause you stress.

Take control of your environment – If the evening news makes you anxious, turn the TV off.

Avoid hot-button topics –If you repeatedly argue about the same subject with the same people, stop bringing it up or excuse yourself when it’s the topic of discussion.

Pare down your to-do list –If you’ve got too much on your plate, distinguish between the “shoulds” and the “musts.”

2. Alter the situation

If you can’t avoid a stressful situation, try to alter it. Figure out what you can do to change things so the problem doesn’t present itself in the future.

Express your feelings instead of bottling them up. If something or someone is bothering you, communicate your concerns in an open and respectful way.
Be willing to compromise. When you ask someone to change their behavior, be willing to do the same.

Be more assertive. Deal with problems head on, doing your best to anticipate and prevent them.

Manage your time better. Plan ahead and make sure you don’t overextend yourself.

3. Adapt to the stressor

If you can’t change the stressor, change yourself. You can adapt to stressful situations and regain your sense of control by changing your expectations and attitude.

Reframe problems. Try to view stressful situations from a more positive perspective.

Look at the big picture. Will it matter in a month, or a year?

Adjust your standards. Set reasonable standards for yourself and others, and learn to be okay with “good enough.”

Focus on the positive. When stress is getting you down, take a moment to reflect on all the things you appreciate in your life, including your own positive qualities and gifts.

4. Accept what you can’t change

Some sources of stress are unavoidable, in such cases; the best way to cope with stress is to accept things as they are. Acceptance may be difficult, but in the long run, it’s easier than railing against a situation you can’t change.

Don’t try to control the uncontrollable. Focus on the things you can control such as the way you choose to react to problems.

Look for the upside. As the saying goes, “What doesn’t kill us makes us stronger.” When facing major challenges, try to look at them as opportunities for personal growth.

Share your feelings. Talk to a trusted friend or make an appointment with a therapist.

Learn to forgive. Accept the fact that we live in an imperfect world and that people make mistakes.

Addiction Hijacks the Brain

≈ Comments Off on Addiction Hijacks the Brain

You’ve probably heard of the brain’s reward network. It’s activated by basic needs — including food, water and sex — and releases a surge of the feel-good neurotransmitter dopamine when those needs are met. But it can also be hijacked by drugs, which lead to a greater dopamine release than those basic needs. Brain-0020.jpg

But the reward network isn’t the only brain network altered by drug use. A new review concluded that drug addiction affects six main brain networks: the reward, habit, salience, executive, memory and self-directed networks.

In 2016, a total of 20.1 million people ages 12 and older in the U.S. had a substance-use disorder, according to the National Survey on Drug Use and Health, an annual survey on drug use. And drug addiction, regardless of the substance used, had surprisingly similar effects on the addicted brain, said the new review, published yesterday (June 6) in the journal Neuron.

The review looked at more than 100 studies and review papers on drug addiction, all of which studied a type of brain scan called functional magnetic resonance imaging (fMRI).

More than half of the studies out there look at the effects of drug use on the reward network, said Anna Zilverstand, lead author of the new review and an assistant professor of psychiatry at the Icahn School of Medicine at Mount Sinai in New York City. [7 Ways Alcohol Affects Your Health]

“Because we showed that the effects are very distributed across the six different networks … [we can conclude that] an approach that only looks at one of these networks isn’t really justified,” Zilverstand told Live Science. “This [finding] will hopefully lead other researchers to look beyond the reward network.”

For example, the memory network is pretty much ignored in research on substance-use disorders, Zilverstand said. This network allows humans to learn non-habit-based things, such as a new physics concept or a history lesson. Some research has suggested that in people with substance-use disorders, stress shifts the person’s learning and memory away from the memory network to the habit network, which drives automatic behavior, such as seeking and taking drugs.

Another less-studied network is the self-directed network, which is involved in self-awareness and self-reflection, the review said. In people with addictions, this network has been associated with increasing craving.

Two other networks are involved in substance-use disorders: The executive network is normally responsible for goal-maintaining and execution, but drugs can alter this network as well, reducing a person’s ability to inhibit their actions. The salience network picks up important cues in a person’s environment and redirects the individual’s attention to them. (In people with drug addiction, attention is redirected toward drugs, increasing craving and drug-seeking.)

Which comes first, the brain activity or the drug use?

“For me, the most surprising [finding] was how consistent the effects were across addictions,” Zilverstand said. What’s more, “the fact that the effects are quite independent of the specific drug use points to them being something general that might actually precede drug use rather than be a consequence of drug use.”

Zilverstand said she hopes that more studies will look at whether some people have abnormal brain activity in these six networks naturally and if that activity just gets exacerbated if they begin drug use. It’s important to know if some of these traits precede drug use; if that’s the case, it might be possible to identify people who are prone to addiction and intervene before an addiction begins, she said.

Some research has pointed toward this possibility already. For example, studies have shown that some people have “difficulties … inhibiting impulsiveness before drug use,” Zilverstand said. “Some of these impairments precede drug use, and they may become worse with more drug use, but they exist before the problem escalates.”

The good news, however, is that activity in four of these networks — executive, reward, memory and salience — moves back toward “normal” once drug use ends. “We know that four of the networks (partially — not fully) recover but not yet what happens to the other two networks,” Zilverstand said in an email.

Zilverstand added that she’s particularly excited about an ongoing study called the Adolescent Brain Cognitive Development (ABCD) Study, which is tracking 10,000 children across the U.S. from around ages 9 or 10 to age 20 (the children are now around 13). Some of these individuals will inevitably become addicted to drugs, most likely marijuana or alcohol, Zilverstand said.

“We’ll be able to see if the effects that we found [in the review] exist in youth who have not yet abused drugs,” she said, and she predicted that researchers will be able to find a lot of the effects identified in the review in the six brain networks.

The authors noted that because some regions of the brain are very small — for example, the amygdala, which is found toward the center of the brain — the studies can’t identify strong signals from those areas on brain scans. So, it’s possible that drugs affect additional networks in the brain that are hidden because of the limitations of our technologies, Zilverstand said.

“We don’t want to conclude that [those effects] don’t exist,” she said.

According to scientists from Harvard and Boston University, meditation produces enduring changes in emotional processing in the brain according to an article published in November of 2012 in the journal Frontiers in Human Neuroscience.
Researchers trained people with one of two different types of meditation, mindful meditation and compassionate meditation over an 8 week period. They measured activity in the brain using functional MRIs 3 weeks before the study and at 3 weeks after and noted what happened to areas of the brain related to compassion. They found the those people who learned compassionate meditation had a different and more loving response 3 weeks after the course even when not meditating.

 

 

Self-Control Can Drain Your Memory

The human body has a finite amount of resources, and scientists are always discovering more about how these resources are shared, depleted, and replenished. Now a new study suggests that the areas in your brain responsible for self-control and forming memories are closely linked – in other words, if you’re concentrating hard on staying disciplined, you’re probably becoming less adept at remembering what’s happening.

Researchers Yu-Chin Chiu and Tobias Egner from Duke University in the US asked a group of volunteers to recognise a series of faces, both with and without the inclusion of a self-control test in the middle. They found that having to exercise self-control had a negative impact on the participants’ ability to recall which pictures they’d previously seen. The same experiment was then repeated with a new set of volunteers and brain-scanning fMRI (functional magnetic resonance imaging) equipment on hand. Brain-0008.jpg

The pair discovered that one area of the brain – the ventrolateral prefrontal cortex – was activated frequently during the self-control test and predicted the strength of the volunteers’ memory later on. The findings suggest that self-control and memory compete for the same resources inside the brain, and support the theory that inhibiting ourselves can also cause us to forget more easily.

“The control demands of response inhibition divert attention away from stimulus encoding, thereby weakening memory traces for inhibitory cues,” the researchers conclude in The Journal of Neurosience. “These findings shed new light on the relation between the control process of response inhibition and the cognitive domains of perception, attention, and memory.”

The self-control test used was a traditional Go/No-Go task: these tasks work by asking participants to view a series of items and push a button only when certain criteria are met – in the case of this experiment, when the face shown is male rather than female. The theory is that those who are able to hold back from a button push when necessary are those with the strongest self-control (or “response inhibition”, as neuroscientists like to call it). The participants were not told in advance that they would need to remember the faces they were shown.

“The scans revealed that responding to a cue and inhibiting a response produced overlapping activation patterns in brain regions within the right frontal and parietal lobes, a network that has previously been implicated in response inhibition,” Mo Costrandi reports for The Guardian. “Crucially, ‘no-go’ trials produced greater activation of this network than ‘Go’ trials, and activity in one specific brain region (the ventrolateral prefrontal cortex) predicted the strength of the participants’ memory, such that the greater the observed network activation, the more likely the participants were to forget that face later on.”

The researchers admit their theory is still “speculative” for now, but if further study confirms the link, they believe their discovery could be used to treat people who have problems with self-control: those suffering from ADHD (Attention Deficit Hyperactivity Disorder), for example, or some form of addiction.

One scenario put forward by the pair is having to suddenly cancel a lane change on the motorway because a car is already in the spot you want to move into. If they’re right, the act of having to control and inhibit your actions would make it less likely that you would remember the details of the incident – such as the make and model of the car that was blocking your path.

Drugs and the Brain

The human brain is the most complex organ in the body. This three-pound mass of gray and white matter sits at the center of all human activity—you need it to drive a car, to enjoy a meal, to breathe, to create an artistic masterpiece, and to enjoy everyday activities. In brief, the brain regulates your body’s basic functions; enables you to interpret and respond to everything you experience; and shapes your thoughts, emotions, and behavior.

The brain is made up of many parts that all work together as a team. Different parts of the brain are responsible for coordinating and performing specific functions. Drugs can alter important brain areas that are necessary for life-sustaining functions and can drive the compulsive drug abuse that marks addiction. Brain areas affected by drug abuse include:

  • The brain stem, which controls basic functions critical to life, such as heart rate, breathing, and sleeping.
  • The cerebral cortex, which is divided into areas that control specific functions. Different areas process information from our senses, enabling us to see, feel, hear, and taste. The front part of the cortex, the frontal cortex or forebrain, is the thinking center of the brain; it powers our ability to think, plan, solve problems, and make decisions.
  • The limbic system, which contains the brain’s reward circuit. It links together a number of brain structures that control and regulate our ability to feel pleasure. Feeling pleasure motivates us to repeat behaviors that are critical to our existence. The limbic system is activated by healthy, life-sustaining activities such as eating and socializing—but it is also activated by drugs of abuse. In addition, the limbic system is responsible for our perception of other emotions, both positive and negative, which explains the mood-altering properties of many drugs.

How do the parts of the brain communicate?

The brain is a communications center consisting of billions of neurons, or nerve cells. Networks of neurons pass messages back and forth among different structures within the brain, the spinal cord, and nerves in the rest of the body (the peripheral nervous system). These nerve networks coordinate and regulate everything we feel, think, and do.

  • Neuron to Neuron
    Each nerve cell in the brain sends and receives messages in the form of electrical and chemical signals. Once a cell receives and processes a message, it sends it on to other neurons.
  • Neurotransmitters – The Brain’s Chemical Messengers
    The messages are typically carried between neurons by chemicals called neurotransmitters.
  • Receptors – The Brain’s Chemical Receivers
    The neurotransmitter attaches to a specialized site on the receiving neuron called a receptor. A neurotransmitter and its receptor operate like a “key and lock,” an exquisitely specific mechanism that ensures that each receptor will forward the appropriate message only after interacting with the right kind of neurotransmitter.
  • Transporters – The Brain’s Chemical Recyclers
    Located on the neuron that releases the neurotransmitter, transporters recycle these neurotransmitters (that is, bring them back into the neuron that released them), thereby shutting off the signal between neurons.

To send a message, a brain cell (neuron) releases a chemical (neurotransmitter) into the space (synapse) between it and the next cell. The neurotransmitter crosses the synapse and attaches to proteins (receptors) on the receiving brain cell. This causes changes in the receiving cell—the message is delivered.

How do drugs work in the brain?

Drugs are chemicals that affect the brain by tapping into its communication system and interfering with the way neurons normally send, receive, and process information. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter. This similarity in structure “fools” receptors and allows the drugs to attach onto and activate the neurons. Although these drugs mimic the brain’s own chemicals, they don’t activate neurons in the same way as a natural neurotransmitter, and they lead to abnormal messages being transmitted through the network.

Other drugs, such as amphetamine or cocaine, can cause the neurons to release abnormally large amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals. This disruption produces a greatly amplified message, ultimately disrupting communication channels.

How do drugs work in the brain to produce pleasure?

Most drugs of abuse directly or indirectly target the brain’s reward system by flooding the circuit with dopamine. Dopamine is a neurotransmitter present in regions of the brain that regulate movement, emotion, motivation, and feelings of pleasure. When activated at normal levels, this system rewards our natural behaviors. Overstimulating the system with drugs, however, produces euphoric effects, which strongly reinforce the behavior of drug use—teaching the user to repeat it.

Most drugs of abuse target the brain’s reward system by flooding it with dopamine.

soa_014_large

How does stimulation of the brain’s pleasure circuit teach us to keep taking drugs?

Our brains are wired to ensure that we will repeat life-sustaining activities by associating those activities with pleasure or reward. Whenever this reward circuit is activated, the brain notes that something important is happening that needs to be remembered, and teaches us to do it again and again without thinking about it. Because drugs of abuse stimulate the same circuit, we learn to abuse drugs in the same way.

Why are drugs more addictive than natural rewards?

When some drugs of abuse are taken, they can release 2 to 10 times the amount of dopamine that natural rewards such as eating and sex do.15 In some cases, this occurs almost immediately (as when drugs are smoked or injected), and the effects can last much longer than those produced by natural rewards. The resulting effects on the brain’s pleasure circuit dwarf those produced by naturally rewarding behaviors.16,17The effect of such a powerful reward strongly motivates people to take drugs again and again. This is why scientists sometimes say that drug abuse is something we learn to do very, very well.

Long-term drug abuse impairs brain functioning.

What happens to your brain if you keep taking drugs?

For the brain, the difference between normal rewards and drug rewards can be described as the difference between someone whispering into your ear and someone shouting into a microphone. Just as we turn down the volume on a radio that is too loud, the brain adjusts to the overwhelming surges in dopamine (and other neurotransmitters) by producing less dopamine or by reducing the number of receptors that can receive signals. As a result, dopamine’s impact on the reward circuit of the brain of someone who abuses drugs can become abnormally low, and that person’s ability to experience anypleasure is reduced.

This is why a person who abuses drugs eventually feels flat, lifeless, and depressed, and is unable to enjoy things that were previously pleasurable. Now, the person needs to keep taking drugs again and again just to try and bring his or her dopamine function back up to normal—which only makes the problem worse, like a vicious cycle. Also, the person will often need to take larger amounts of the drug to produce the familiar dopamine high—an effect known as tolerance.

Decreased Dopamine Transporters in a Methamphetamine Abuser18

soa_015.gif

How does long-term drug taking affect brain circuits?

We know that the same sort of mechanisms involved in the development of tolerance can eventually lead to profound changes in neurons and brain circuits, with the potential to severely compromise the long-term health of the brain. For example, glutamate is another neurotransmitter that influences the reward circuit and the ability to learn. When the optimal concentration of glutamate is altered by drug abuse, the brain attempts to compensate for this change, which can cause impairment in cognitive function. Similarly, long-term drug abuse can trigger adaptations in habit or non-conscious memory systems. Conditioning is one example of this type of learning, in which cues in a person’s daily routine or environment become associated with the drug experience and can trigger uncontrollable cravings whenever the person is exposed to these cues, even if the drug itself is not available. This learned “reflex” is extremely durable and can affect a person who once used drugs even after many years of abstinence.

What other brain changes occur with abuse?

Chronic exposure to drugs of abuse disrupts the way critical brain structures interact to control and inhibit behaviors related to drug use. Just as continued abuse may lead to tolerance or the need for higher drug dosages to produce an effect, it may also lead to addiction, which can drive a user to seek out and take drugs compulsively. Drug addiction erodes a person’s self-control and ability to make sound decisions, while producing intense impulses to take drugs.

The Pew Research Center has been polling American adults on their perceptions of China since 2005. The latest report, based on interviews conducted in March 2020, shows that growing numbers of Americans have become increasingly negative about China. For the first time, more than half of Americans between the ages of 18 and 29 held unfavorable views of China. Almost nine in ten Americans see China’s power and influence in the world as a threat, with 62% saying that it is a “major threat.”
