Lately I’ve come across a lot of research touting the heart benefits of a specific technique that’s seemingly taking the alternative health world by storm…
A technique that optimizes one of your body’s most powerful built-in systems.
A system that athletes, coaches, biohackers, and thousands of health-conscious people are striving to better track, understand, and optimize.
Understanding your HRV
This system is called heart rate variability, or HRV—a reliable health marker that can indicate your current state of health and fitness.
HRV measures the variation in time intervals between your heart beats. Some periods between heart beats may be quicker, and some slower—which is completely normal (and actually healthy).
This is an important measurement because HRV is controlled by your autonomic nervous system (ANS) which regulates your heart rate, blood pressure, breathing, and digestion.
Your ANS has two branches: your parasympathetic system (or your “rest and digest” response) and your sympathetic system (or your “fight or flight” response).
A low HRV has been linked to depression and anxiety, when your sympathetic system is dominant. And in more serious cases, this can increase the risk of cardiovascular disease and death.
But a higher HRV indicates that both parasympathetic and sympathetic systems are functioning properly and in balance—meaning you have a healthy, resilient ANS. In other words, the healthier your ANS, the faster your body is able to switch gears from calm and rested to proactive and alert.
And when your ANS system is strong, you tend to bounce back from stress more quickly—a very important factor when it comes to good health… particularly your cardiovascular health.
Fix your whole-body health with this simple technique
The big discovery the latest studies have made is that it’s possible to transform (or maintain) your HRV—and as a result, your whole-body health—with one simple technique.
Researchers have recently observed the profound effects this technique—a simple shift in your breathing rhythm—can have on improving your HRV and overall heart health.
The researchers found that this change in breathing pattern increases your heart rate variability (HRV). (Again, having a high HRV is a good thing.)
But the key to achieving this health-boosting breathing rhythm is to breathe at a 0.1 hertz (Hz) frequency.
“Frequency,” in this case, refers to how many times per minute you breathe.
Right now, you probably breathe around 12 to 15 breaths per minute—a normal breathing rate for most adults.
But breathing at 0.1 Hz frequency—a common form of slow, deep breathing—works out to be about half that much... approximately six breaths per minute.
At this rate of frequency, your heart rate and breathing rate eventually sync up, which helps your body produce your highest HRV levels.
To further illustrate the effects of 0.1 Hz breathing, another study from Brigham Young University in Provo, Utah, researchers split 95 study participants into two groups.
One group participated in the 0.1 Hz breathing technique for 15 minutes, while the others sat quietly for the same length of time.
Afterward, the researchers took various measurements. They found that those in the breathing group exhibited a higher HRV, lower systolic blood pressure, as well as a more positive mood.
The study participants who sat quietly showed no improvement in their heart measures and actually reported a decline in mood.
Control your breathing rhythms for peak heart health
So how can you achieve a 0.1 Hz breath frequency? It’s pretty simple, actually.
Give this a try:
Deliberately and regularly slowing your breathing is an effective, all-natural, and inexpensive way to strengthen your resilience to stress and improve your overall heart health.
Consider making this exercise a part of one of your established daily routines—perhaps during a daily walk, on your evening commute, or right before bedtime.
Sometimes all it takes is something as simple as 15 minutes a day to activate your body’s built-in healing systems and transform your health. Remember, oftentimes, the tools we’re born with can work better than anything money can buy… it’s all a matter of knowing the right way to use them.
