While it
is obvious that your feelings can influence your movement, it is not as obvious
that your movement can impact your feelings too. For example, when you feel
tired and sad, you may move more slowly. When you feel anxious, you may either
rush around or become completely paralyzed. But recent studies show that the
connection between your brain and your body is a “two-way street” and that
means movement can change your brain, too!
How exercise can improve mood
disorders
Regular
aerobic exercise can reduce anxiety by making your brain’s “fight or flight”
system less reactive. When anxious people are exposed to physiological changes
they fear, such as a rapid heartbeat, through regular aerobic exercise, they
can develop a tolerance for such symptoms.
Regular
exercise such as cycling or gym-based aerobic, resistance, flexibility, and
balance exercises can also reduce depressive symptoms. Exercise can be as
effective as medication and psychotherapies. Regular exercise may boost mood by
increasing a brain protein called BDNF that helps nerve fibers grow.
For people
with attention-deficit disorder (ADHD), another study showed that a single
20-minute bout of moderate-intensity cycling briefly improved their symptoms.
It enhanced the participants’ motivation for tasks requiring focused thought,
increased their energy, and reduced their feelings of confusion, fatigue, and
depression. However, in this study, exercise had no effect on attention or
hyperactivity per se.
Meditative
movement has been shown to alleviate depressive symptoms. This is a type of
movement in which you pay close attention to your bodily sensations, position
in space, and gut feelings (such as subtle changes in heart rate or breathing)
as you move. Qigong, tai chi, and some forms of yoga are all helpful for this.
For example, frequent yoga practice can reduce the severity of symptoms in
post-traumatic stress disorder to the point that some people no longer meet the
criteria for this diagnosis. Changing your posture, breathing, and rhythm can
all change your brain, thereby reducing stress, depression, and anxiety, and
leading to a feeling of well-being.
The surprising benefits of
synchronizing your movements
Both
physical exercise and meditative movement are activities that you can do by
yourself. On their own, they can improve the way you feel. But a recent study
found that when you try to move in synchrony with someone else, it also
improves your self-esteem.
In 2014,
psychologist Joanne Lumsden and her colleagues conducted a study that required
participants to interact with another person via a video link. The person
performed a standard exercise — arm curls — while the participants watched, and
then performed the same movement.
The “video
link” was in fact a pre-recorded video of a 25-year-old female in a similar
room, also performing arm curls. As part of the experiment, participants had to
either coordinate their movement or deliberately not coordinate their movement
with the other person’s arm curls. They filled out a mood report before and
after each phase of synchronizing or falling out of synchrony. They also
reported on how close they felt to the other person.
The
results were interesting. When subjects intentionally synchronized their
movement with the recording, they had higher self-esteem than when they did
not. Prior studies had shown that synchronizing your movement with others makes
you like them more. You also cooperate more with them and feel more charitable
toward them. In fact, movement synchrony can make it easier to remember what
people say and to recall what they look like. This was the first study to show
that it makes you feel better about yourself, too. That’s probably why dance
movement therapy can help depressed patients feel better.
Putting it all together
Your mind
and body are intimately connected. And while your brain is the master control
system for your body’s movement, the way you move can also affect the way you
think and feel.
Movement
therapies are often used as adjunctive treatments for depression and anxiety
when mental effort, psychotherapy, or medication is not enough. When you are
too exhausted to use thought control strategies such as focusing on the
positive, or looking at the situation from another angle, movement can come to
the rescue. By working out, going on a meditative walk by yourself, or going
for a synchronized walk with someone, you may gain access to a “back door” to
the mental changes that you desire without having to “psych yourself” into
feeling better.
The holidays are coming so if you plan on celebrating with a few drinks ,read this first.
Straight to Your Head
Thirty
seconds after your first sip, alcohol
races into your brain. It slows down the chemicals and pathways that your brain
cells use to send messages. That alters your mood, slows your reflexes, and
throws off your balance. You also can’t think straight, which you may not
recall later, because you’ll struggle to store things in long-term memory
Your Brain Shrinks
If you
drink heavily for a long time, booze can affect how your brain looks and works.
Its cells start to change and even get smaller. Too much alcohol can actually
shrink your brain. And that’ll have big effects on your ability to think,
learn, and remember things. It can also make it harder to keep a steady body
temperature and control your movements.
Does It Help You Sleep?
Alcohol’s
slow-down effect on your brain can make you drowsy, so you may doze off more
easily. But you won’t sleep well. Your body processes alcohol throughout the
night. Once the effects wear off, it leaves you tossing and turning. You don’t
get that good REM sleep your body needs to feel restored. And you’re more
likely to have nightmares and vivid dreams. You’ll also probably wake up more
often for trips to the bathroom.
More Stomach Acid
Booze
irritates the lining of your stomach and makes your digestive juices flow. When
enough acid and alcohol build up, you get nauseated and you may throw up. Years
of heavy drinking can cause painful sores called ulcers in your stomach. And
high levels of stomach juices mean you won’t feel hungry. That’s one reason
long-term drinkers often don’t get all the nutrients they need.
Diarrhea and Heartburn
Your small
intestine and colon get irritated, too. Alcohol throws off the normal speed
that food moves through them. That’s why hard drinking can lead to diarrhea,
which can turn into a long-term problem. It also makes heartburn more likely –
it relaxes the muscle that keeps acid out of your esophagus, the tube that
connects your mouth and stomach.
Why You Have to Pee … Again
Your brain
gives off a hormone that keeps your kidneys from making too much urine. But
when alcohol swings into action, it tells your brain to hold off. That means
you have to go more often, which can leave you dehydrated. When you drink
heavily for years, that extra workload and the toxic effects of alcohol can wear
your kidneys down.
The Steps to Liver Disease
Your liver
breaks down almost all the alcohol you drink. In the process, it handles a lot
of toxins. Over time, heavy drinking makes the organ fatty and lets thicker,
fibrous tissue build up. That limits blood flow, so liver cells don’t get what
they need to survive. As they die off, the liver gets scars and stops working
as well, a disease called cirrhosis.
Pancreas Damage and Diabetes
Normally,
this organ makes insulin and other chemicals that help your intestines break
down food. But alcohol jams that process up. The chemicals stay inside the
pancreas. Along with toxins from alcohol, they cause inflammation in the organ,
which can lead to serious damage. After years, that means you won’t be able to
make the insulin you need, which can lead to diabetes. It also makes you more
likely to get pancreatic cancer.
What’s a Hangover?
That
cotton-mouthed, bleary-eyed morning-after is no accident. Alcohol makes you
dehydrated and makes blood vessels in your body and brain expand. That gives
you your headache. Your stomach wants to get rid of the toxins and acid that
booze churns up, which gives you nausea and vomiting. And because your liver
was so busy processing alcohol, it didn’t release enough sugar into your blood,
bringing on weakness and the shakes.
An Offbeat Heart
One night
of binge drinking can jumble the electrical signals that keep your heart’s
rhythm steady. If you do it for years, you can make those changes permanent.
And, alcohol can literally wear your heart out. Over time, it causes heart
muscles to droop and stretch, like an old rubber band. It can’t pump blood as
well, and that impacts every part of your body.
A Change in Body Temperature
Alcohol
widens your blood vessels, making more blood flow to your skin. That makes you
blush and feel warm and toasty. But not for long. The heat from that extra
blood passes right out of your body, causing your temperature to drop. On the
other hand, long-term, heavy drinking boosts your blood pressure. It makes your
body release stress hormones that narrow blood vessels, so your heart has to
pump harder to push blood through.
A Weaker Immune System
You might
not link a cold with a night of drinking, but there might be a connection.
Alcohol puts the brakes on your immune system. Your body can’t make the numbers
of white blood cells it needs to fight germs. So for 24 hours after drinking,
you’re more likely to get sick. Long-term, heavy drinkers are much more likely
to get illnesses like pneumonia and tuberculosis.
Hormone Havoc
These
powerful chemicals manage everything from your sex drive to how fast you digest
food. To keep it all going smoothly, you need them in the right balance. But
alcohol throws them out of whack. In women, that can knock your periods off
cycle and cause problems getting pregnant. In men, it can mean trouble getting
an erection, a lower sperm count, shrinking testicles, and breast growth.
Hearing Loss
Alcohol
impacts your hearing, but no one’s sure exactly how. It could be that it messes
with the part of your brain that processes sound. Or it might damage the nerves
and tiny hairs in your inner ear that help you hear. However it happens,
drinking means you need a sound to be louder so you can hear it. And that can
become permanent. Long-term drinkers often have hearing loss.
Thin Bones, Less Muscle
Heavy
drinking can throw off your calcium levels. Along with the hormone changes that
alcohol triggers, that can keep your body from building new bone. They get
thinner and more fragile, a condition called osteoporosis. Booze also limits
blood flow your muscles and gets in the way of the proteins that build them up.
Over time, you’ll have lower muscle mass and less strength.
Bottom Line: Moderation is the key
Overweight vs overfat: Is your scale lying to you?
You may be storing unhealthy amounts of visceral fat even if your weight appears normal.
For decades, the body mass index (BMI) has been the gold standard for gauging obesity-related heart disease risk. But this handy tool doesn't always tell the whole story. It extrapolates your body fat percentage based on your height and weight . But the formula can't assess how or where your body stores its excess fat — a distinction that is crucial for cardiovascular health. By some estimates, the BMI misclassifies nearly 50% of people who are at higher disease risk from excess fat, meaning that you can be overfat even when you're not overweight.
The secret life of belly fat
Some people are genetically programmed to have a lot of fat tissue under the skin, which is deployed to store extra food energy during times of scarcity. But other people have very few of these designated fat cells, explains Dr. Christos Mantzoros, professor of medicine at Harvard-affiliated Beth Israel Deaconess Medical Center.
In individuals who lack an adequate quota of available fat storage cells (or people whose fat tissue is already filled to capacity), fat particles travel in the bloodstream and congregate in the liver, muscles, and other organs, which normally have no fat. This also leads to the accumulation of visceral or "belly" fat — a pattern of fat distribution that is particularly hazardous to your health (see "Who is prone to visceral fat?"). Visceral fat is associated with insulin resistance and other metabolic irregularities. "It also triggers the release of inflammatory substances that damage the arteries and help set the stage for cardiovascular disease," says Dr. Mantzoros.
Who is prone to visceral fat?
The tendency to accumulate visceral fat is governed by genetic, ethnic, and gender differences. For example, people who inherit two copies (one from each parent) of a mutation in a gene involved in fat metabolism are more likely to have higher amounts of visceral fat than people with just one copy. Those without any copies of the gene mutation are less likely to develop heart disease — even if they become obese. Natives of India and South Asia have a higher-than-average propensity for abdominal obesity. And white men and black women tend to accumulate more visceral fat than black men and white women.

Fat and aging
With age, people tend to lose muscle tissue, especially the type of specialized muscle fibers that produce quick bursts of speed and power. Fat frequently accumulates within the remaining muscle tissue, causing your body fat percentage to increase even when your weight remains constant. This scenario is closely linked to bodywide inflammation and diabetes risk. It may also explain why your BMI measurement doesn't provide a true reflection of your health risks.
Evidence suggests that waist circumference and waist-to-hip ratio are better indicators of metabolic health than BMI. Even among people with the same BMI, those who have a large waist (defined as more than 40 inches for men and 35 inches for women) have a significantly higher risk. In addition, people who tend to carry their weight in their hips and thighs (a "pear" shape) have lower waist-to-hip ratios and are less prone to heart disease than people with abdominal obesity (an "apple" shape); see "Measuring your midsection."
Measuring your midsection
To measure your waist accurately, exhale and wrap a measuring tape around your bare abdomen just above your navel (belly button). Don't suck in your gut or pull the tape tight enough to squeeze the area.
To compute your waist-to-hip ratio, first measure your hips by putting the tape measure around the widest part of your buttocks. Keep the tape measure level. Then, divide your waist size by your hip size.

What should you do about visceral fat?
People with abdominal obesity — even if they're not overweight — can lessen their heart disease risk with regular exercise and healthy eating habits. "Reducing the total amount of fat in your body frees up storage space for fat particles in places that are associated with less metabolic risk," says Dr. Mantzoros. That's why losing as little as 7% of your total weight helps lower heart disease risk: the most dangerous visceral fat disappears first.
