Lasers - can they regulate your heart?

Your heartbeat marks the fact that you are alive. For some of us, though, the regulation of the heartbeat becomes dysfunctional.

In such cases, it may need a pacemaker to regulate the beating of the heart.

A pacemaker works by installing a small device the size of a coin with wires connected to your heart. The wires sense the beating of the heart.

In case the rhythym is not what it ought to be, it sends a small electric pulse that will make the heart beat.

For people around the world with a dysfunctional heartbeat, a pacemaker has been a godsend.

But researchers have not found an ingenious way of doing this, perhaps even without invasive surgery.

A research team led by Dr. Andrew Rollins at Case Western Reserve University has been studying the use of laser lights.

Their objective was to understand the use of lasers to regulate heart muscles.

In the past, laser lights have been shown to be effective on small groups of muscles.

Recently, they found that the same technique could be used to regulate the entire heart.

So think of a tiny device sitting on your chest, sending laser lights to your heart, and regulating its beating.

No surgery required, no devices that need to be installed or, worse, reinstalled after a few years.

I know a large part of my content is geared toward preventive health. Ensuring that we do not allow our body to fail us such that we need medical intervention.

But medical science is as magical as preventive health care; a laser light regulating your heartbeat is one example.

One of the challenges of a pacemaker is that you need to set it to a constant. Your heart does not beat that way.

Instead, you have something known as heart rate variability, or HRV. HRV is the natural variability of your heartbeat.

Perhaps with laser lights, we can restore the heartbeat and also retain variability.

Sensors - the future

Sensors are devices that detect a change. Light, sound, or smoke, for example. But what might the future of sensors hold for your personal health? Most of us have used simple sensors. Temperature gauge. Blood pressure. But in the not-too-distant future, we might scoff at these simple devices. Let us

Reversal or Remission?

We have come a long way. About a decade ago, when I started my amazing health transformation, most of the people I met were skeptics. The thrust of the argument I would hear would be that there was no way to reverse a disease. In essence, diseases were a one

But then he died

I was recently reading a book on beating cancer. The author outlined the steps he had taken to beat grade III colon cancer successfully. Then I realized he had recently died of cancer. Naturally, my first instinct was to question everything he had said. He had rejected chemotherapy. He had

Preferences - do you have any?

Quick, tell me what your preferences are for food. Ok, at least think of things you like. What if I told you that you do not really have any preferences? What if I told you that your preferences are malleable depending on the circumstances and what you are being told
