Music and your health.

"If music be the food of love, play on" 

                                                           

                                 (William Shakespeare)

When we read that we are bound to agree. Music has been an integral part of most civilizations and still is. Mankind has used music in so many ways; to entertain, to express emotions and get feelings across, to heal and recover, to relax and meditate, and to learn or record facts and history to name a few.

Music is like the soundtrack of our lives. How often we hear a song and can right away be transported to another time, another place where we heard it first or where it impacted us. How often has music brightened up our mood or helped us relax. How many times has music brought so many together, that is why it is the universal language. It is clear that we need music in our lives,  “Without music, life would be a mistake.” as Friedrich Nietzsche concluded.

Over the decades, countless studies and continued research work has repeatedly supported the belief that music can be more than just food for the soul, it can have real beneficial effects on our overall health and well-being. Here are some of those benefits:

Physical benefits

Pain:
According to a study published in Frontiers of Psychology, scientists found that listening to music that is relaxing, highly pleasant, familiar, and self-chosen, reduced pain and increase functional mobility in fibromyalgia patients.

Endurance:
British researchers studied 12 healthy male college students riding stationary bikes while listening to six different songs of their choosing, each with a different tempo. It was observed that not only their pedaling speed changed along with the tempo of the music so did their overall affect. As tempo slowed, they slowed the pedaling, their heart rate decreased, breathing slowed and mileage fell. But as music tempo increased so did their pedaling speed, heart rate, distance covered and showed reduced exertion. Hence the conclusion 'healthy individuals performing submaximal exercise not only worked harder with faster music but also chose to do so and enjoyed the music more when it was played at a faster tempo."
In another study, researchers had 20 moderately active adults (22±4 y), unfamiliar with interval exercise, complete an acute session of SIT(Sprint Interval training) under two different conditions: music and no music. Leading to the conclusion ' Music enhanced in-task performance and enjoyment of an acute bout of SIT.'

Post-exercise recovery:
After a workout music not only helps relax, it also helps the body recover faster. A study published in the Journal of Strength & Conditioning Research showed beneficial effect of both music and rhythm was greater toward the end of the recovery period. Results suggest that listening to music during non structured recovery can be used by professional athletes to enhance recovery from intense exercise.


Sleep:
A study showed classical music to improve the quality of sleep in individuals with poor sleep. Relaxing classical music can thus be used to help alleviate insomnia instead of sleep inducing medications.


Eating Habits:
A recent study found that with softening of the music and lighting while eating, diners end up eating less and enjoying the food more, suggesting that a more relaxed environment increases satisfaction and decreases consumption.

Blood Flow:
Previous studies have demonstrated that music may influence physiologic parameters such as heart rate and blood pressure. A study of the effect of music on endothelial function showed an increased blood flow and a happier mood.


Mental Benefits

Stress:
Over the past years, music has been increasingly used as a therapeutic tool in the treatment of different diseases in healthy and ill subjects over recent years (e.g., the so called "Mozart effect"). Music has been found to lead to release of biochemical measurable stress-reducing effects in some individuals. Some kinds of music have also been known to cause changes in cardiac and neurological functions.
It has also been seen that music helps individuals perform better under pressure if listening to music. Such a study involving basketball players known to choke under pressure, showed improved performance by the same players when listening to upbeat music and lyrics.


Meditation:
Music has been found to cause actual change in brainwave. Researchers found that most music combines many different frequencies that cause a complex set of reactions in the brain, but researchers say specific pieces of music could enhance concentration or promote relaxation.

Mood:
A study found arousal and mood regulation to be the most important dimension of music listening closely followed by self-awareness.

Cognitive function:
Research has shown that upbeat music improves the efficiency and accuracy in performance of workers on assembly lines or quality-control operators. It helps them to stay focused on their work even though what they’re doing is not necessarily interesting, and attention would normally fade over time.

Anxiety:
When used in conjunction with conventional cancer treatments, music therapy has been found to help patients promote a better quality of life; better communicate their fear, sadness, or other feelings; and better manage stress, while alleviating physical pain and discomfort.

Patients:
There is sufficient practical evidence that listening to music while resting in bed after open heart surgery can reduce patients' stress level. Therefore it is recommended that music intervention be offered as an integral part of the multimodal regime offered to patients after cardiovascular surgery. It is a supportive source that increases relaxation. Music is also effective in under conditions and music can be utilized as an effective intervention for patients with depressive symptoms, geriatrics and in pain, intensive care or palliative medicine. However,  music used should be carefully selected incorporating a patient's own preferences to offer an effective method to reduce anxiety and to improve quality of life. The most benefit on health is seen in classic music, meditation music whereas heavy metal music or technosounds are even ineffective or dangerous and will lead to stress and/or life threatening arrhythmias.

Fats are not the enemy

Allison Aubrey presented a case for adding some fat to our diets on  NPR's Morning Edition as few weeks back.

Fats have been the target of most of the popular dietary plans. They are looked upon as the enemy to any healthy lifestyle. But is that justifiable and right?

It is well documented that saturated fats can raise the LDL ( Low-density lipoprotein)in the blood, which is the so-called bad cholesterol. Whereas on the other end, plant-based fats such as those found in nuts and olive oil are actually beneficial to our heart health and can help reduce the risk of heart disease. Yet it seems the risks might be more then the benefits, leading most of us to minimize fats intake whenever trying to eat healthy.

Thus the task of  convincing most of us to bring some ats back into our diets is a tough one.
Here is an excerpts of what experts had to say to Allison Aubrey on the subject;

"Fat was really the villain," says , who is chairman of the department of nutrition at the Harvard School of Public Health. And, by default, people "had to load up on carbohydrates."
But, by the mid-1990s, Willett says, there were already signs that the high-carb, low-fat approach might not lead to fewer heart attacks and strokes. He had a long-term study underway that was aimed at evaluating the effects of diet and lifestyle on health.
"We were finding that if people seemed to replace saturated fat — the kind of fat found in cheese, eggs, meat, butter — with carbohydrate, there was no reduction in heart disease," Willett says.
Willett submitted his data to a top medical journal, but he says the editors would not publish his findings. His paper was turned down.
"There was a lot of resistance to anything that would question the low-fat guidelines," Willett says, especially the guidelines on saturated fat.
Willett's was eventually published by a British medical journal, the BMJ, in 1996.

But here's where it gets interesting: "We've learned that carbohydrates aren't neutral," explains , an epidemiologist at Harvard Medical School.
"[Carbs] were the base of the pyramid," says Mozaffarian. The message was "eat all carbohydrates you want."
Americans took this as a green light to eat more refined grains such as breads, processed snack foods and white pasta.
"But carbohydrates worsen glucose and insulin — they have negative effects on blood cholesterol levels," he says. The thinking that it's OK to swap saturated fats for these refined carbs "has not been useful advice."
He says it's clear that saturated fats can raise LDL cholesterol, the bad cholesterol. But that's only one risk factor for heart disease.
There's now evidence that — compared with carbs — saturated fat can raise HDL cholesterol (the good cholesterol) and lower trigylcerides in the blood, which are both countering effects to heart disease, he says.
"When you put all of this together," says Mozaffarian, what you see is that saturated fat has a relatively neutral effect compared with carbs. He says it's "not a beneficial effect but not a harmful effect. And I think that's what the recent studies show." He points to a of studies published in 2010.
He also points to a highly publicized that concludes there's no convincing evidence to support the dietary recommendations to limit saturated fat.
The in that paper have created quite a bit of controversy. For instance, the American Heart Association it stands by its recommendations to limit saturated fat.


Although these new points of view don't say 'Go ahead and load up on fats' they do make it clear that fats should not be excluded from our diets completely. Maybe moderation is a good way to go with all diets.

Reduce all animal proteins in our diet to live longer

It has been well documented that consumption of too much red meat as an adult can lead increased risk for type 2 diabetes, coronary heart disease, stroke and certain cancers.

Now researchers in the US and Italy have gathered enough data, over a period of two decades, to conclude that individuals who have diets high in animal proteins during their middle age are four times more likely to die of cancer then their counterparts who had diets low in animal proteins. A risk some have compared with smoking. An increased risk of developing Diabetes Type 2 was also observed.

Valter Longo, a University of Southern California gerontology professor and director of the school’s Longevity Institute, who co-authored the study pointed out "The great majority of Americans could reduce their protein intake," and added "The best change would be to lower the daily intake of all proteins, but especially animal-derived proteins."

The interesting finding though was the fact that if you started eating more animal proteins after the age of 66 years, it is actually good for your health.


Here are two articles on the subject:

Too much animal-based proteins could lead to early death, study says ( Brady Dennis for The Washington Post)

Anger really harmful to cardiovascular health

We all lose our temper from time to time, and it never feels good. An angry outburst is almost always leaves on exhausted, unhappy and feeling drained. We've all been told a bad temper and anger are bad for us at some point in our life.
Now a research study conducted at the Harvard School of Public Health, has found that the risk of a heart attack or stroke is much higher for about two hours immediately following an angry outburst. The risk for a heart attack is increased almost five-folds, whereas the risk is increased two-folds for stroke. This finding is more consistent in individuals with preexisting risk factors.
According to the researchers, 'At a population level, the risk with a single outburst of anger is relatively low - one extra heart attack per 10,000 people per year could be expected among people with low cardiovascular risk who were angry only once a month, increasing to an extra four per 10,000 people with a high cardiovascular risk. But the risk is cumulative, meaning temper-prone individuals will be at higher risk still.'

It is not exactly clear how anger causes the increased risk, but a constant rise in stress level might be significant. Chronic stress is known to lead to high blood pressure which itself is a risk factor for heart diseases. Use of alcohol consumption or smoking for relieving the stress might further exacerbate that risk. Yet, further research is required to fully understand how anger could lead to an increased risk of cardiovascular events and what steps might successfully abate that risk.

This study involved the data analysis of nine studies in which anger and cardiovascular events were self-reported over a period of two decades. It was published in the European Heart Journal on March 3rd, 2014.

Shift work clearly detrimental to health

It is a fact that doing the night shift at work is terribly hard. It not only affect our personal and social lives it also throws our whole sleep cycle into chaos. Now scientists at the Sleep Research Center Surrey have found definite proof that night work can lead to long term damage starting at molecular level. Night shift work has been linked to a higher risk of type 2 diabetes, heart attacks and cancer.

According to an article in BBC World News by James Gallagher;
'Experts said the scale, speed and severity of damage caused by being awake at night was a surprise.

The human body has its own natural rhythm or body clock tuned to sleep at night and be active during the day.
It has profound effects on the body, altering everything from hormones and body temperature to athletic ability, mood and brain function.'

Scientists observed 22 individuals as their bodies adjusted from their normal patterns to working the night shift. Preliminary blood test showed that 6% genes had precise daily activity cycles. As the individuals got into a night work routine, these cycles were thrown off. 
The researchers call this 'Chrono-Chaos', here the scientists on the team explain it;

"Over 97% of rhythmic genes become out of sync with mistimed sleep and this really explains why we feel so bad during jet lag, or if we have to work irregular shifts," said Dr Simon Archer, one of the researchers at the University of Surrey.
Fellow researcher Prof Derk-Jan Dijk said every tissue in the body had its own daily rhythm, but with shifts that was lost with the heart running to a different time to the kidneys running to a different time to the brain.
He told the BBC: "It's chrono-chaos. It's like living in a house. There's a clock in every room in the house and in all of those rooms those clocks are now disrupted, which of course leads to chaos in the household."
Prof Dijk added: "We of course know that shift work and jet lag is associated with negative side effects and health consequences.
"They show up after several years of shift work. We believe these changes in rhythmic patterns of gene expression are likely to be related to some of those long-term health consequences."

According to Web MD about 8.6 million people do shift work, meaning either they work the night shift or they rotate shifts during the week.  These include police officers, firefighters, nurses, doctors, pilots, waitresses, truck drivers, and many more professionals. Even a personal trainer who works out at the gym with clients in the early mornings and evenings is a shift worker.
Some of the short term health problems seen more commonly in shift workers are; 

• Gastrointestinal symptoms like upset stomach, nausea, diarrhea, constipation, and heartburn
• Increased risk of injuries and accidents
• Insomnia
• Decreased quality of life
• General feeling of being unwell

Whereas the long term effects on health are harder to measure but there has been compelling proof that shift workers might be more prone to these long term medical problems;

• Cardiovascular disease
• Diabetes and Metabolic Disorder
• Depression and Mood Disorders
• Serious Gastrointestinal Problems
• Obesity
• Problems with Fertility and Pregnancy
• Cancer

 Although most of these long term effects may occur only after decades of disruptive shift work, but some health problems might develop much faster. For many professions shift work is inevitable, hence can not be completely avoided. In those cases, here are some suggestions on the Web MD to help minimize the damage:

• Eat Well and Exercise
• Get enough Sleep
• Change your Schedule
• See your Doctor

Heart Attacks, Strokes and Apples

We all heard our parents encouraging us to eat fresh fruit and vegetable, specially apples, and all of them used the old Victorian saying " An Apple a Day Keeps the Doctor Away" to further motivate us. Well, more then a century later it still holds true, especially for the above 50 population.
According to an article published in the christmas edition of the British Medical Journal, a research study led by Dr Adam Briggs of the BHF Health Promotion Research Group at Oxford University came to the conclusion that about 8500 deaths from heart attacks and strokes could be averted if all adults of 50 years and above were prescribed an a apple a day. The significance of this outcome is more apparent when compared to another recent study that showed that if adults 50 and above not already on it, were prescribed statins, it could prevent about 9400 deaths from heart diseases. 
Dr. Adam Briggs says 'It just shows how effective small changes in diet can be, and that both drugs and healthier living can make a real difference in preventing heart disease and stroke.' But the researchers stress that this does not encourage individuals already on statins to stop taking them, just try adding apples to your daily diet.
Although apples appear to be exceptionally good for maintaining a healthy heart, it is clearly essential to eat a variety of fresh fruits and vegetable on a daily basis to stay healthy.
