Music Found to Significantly Reduce Pain, Anxiety in Postop Heart Surgeries
Given that heart disease is the leading cause of death in the world, prevention and treatment have never been more important. While conventional cardiology relies heavily on pharmaceuticals in the management of cardiac conditions, music has been shown to have remarkable benefits without any side effects—music as medicine.
Ancient cultures understood the healing benefits of music and integrated it into their promotion of health and healing of disease. But this practice was mostly lost in the rise of western medicine. Today, that connection is gradually being restored as a new wave of research is being done on the healing benefits of music on the heart.
One such recent study found that listening to music is linked to a significant reduction in anxiety and pain after major heart surgery. The researchers concluded that clinicians should consider music for patients scheduled for surgery as it has none of the risks or side effects, and many of the benefits of the drugs most commonly used to aid in post-surgery recovery.

Why Do We Sleep? For More Reasons Than You May Think
Most of us spend about a third of our lives asleep, despite not really having an answer to the question, ‘why do we sleep?’ Now neuroscientists are realizing that sleep is more important than previously thought. They’re also realizing that the worn-out platitude, “you can sleep when you die,” is terrible advice, as that day will undoubtedly come sooner if you short yourself on a good night’s sleep.
According to most contemporary research, you should be getting around seven to eight hours of sleep every night, and if you think you can get by on fewer than that, there’s a really good chance you’re fooling yourself.
Why is Sleep Important?
While the exact mechanisms of sleep are still being studied, neuroscientists including Matthew Walker have made interesting learnings about what happens when we deprive ourselves of sleep and the impacts sleep (or lack thereof) has on society as a whole.
When we’re awake, Walker says that essentially, we’re causing low-level brain damage. By this, he is referring to the build-up of the sticky, toxic junk in our brain known as beta-amyloid. This accumulation of beta-amyloid has been found to correspond with the onset of Alzheimer’s, among many other adverse health effects correlated with a lack of sleep.
Sleep is beneficial as more than just a healing function; it also replenishes spent resources and regulates hormone levels that dictate our appetite, cognitive function, and motor skills. The two hormones that dictate whether we are hungry or full, ghrelin and leptin, have been observed to flare up and down, respectively, when we’re sleep deprived. This inevitably leads to an increase in hunger, but even worse, it leads our bodies to crave unhealthy and fattening foods — those heavy on carbs and light on greens. In fact, people who run on four to five hours of sleep per night tend to eat 200-300 more calories per day.
For men, sleep is an important regulator of hormones, most notably testosterone. Sleep-deprived males can have the same virility and strength as a man 10 years their senior. For women, a lack of sleep can lead to a significantly increased risk of breast cancer and drops in immune hormones.
According to Walker, just introducing a single night of just four hours of sleep among a normal eight-hour sleep schedule, can bring about a 70 percent drop in natural cancer-killing cells, the immune assassins that target malignant carcinogens. Every day our bodies produce these cells and others to fend off disease and maintain our health, and while a cat nap might make you feel refreshed, it won’t make up for the loss of these cells.
