The validity of HRV results using wearables has been questioned in academia. Wearable devices usually adopt photoplethysmography (PPG), using the photo sensors in the device, rather than electrocardiograph (ECG) that is used in medical and strap based heart rate monitors (HRM), to measure HRV. The top wearable devices use algorithms to compensate for the inaccuracies… Continue reading Using wearables to measure HRV

Resting Heart Rate and mortality
Men with a resting hearth rate (RHR) of over 75 beats per minute at 50 years of age have twice as high risk of all-cause death, cardiovascular disease and coronary heart disease during 21 years of follow-up compared with men with RHR of 55 beats per minute or below[1]Impact of changes in heart rate with age on all-cause death and… Continue reading Resting Heart Rate and mortality
Getting the most out of HRV Health
Heart rate variability is a science. To get the most out of the HRV Health Platform requires a scientific approach. Firstly, as a new user you need to establish a base line to see what your HRV metrics are for your current state of health. This requires taking readings at the same time each day,… Continue reading Getting the most out of HRV Health
People with high HRV live longer
HRV declines with age[1]RMSSD by age and gender. When looking at the statistics it appears that the rate of declines slows as we get older, and then reverses after 80[2]Relation of high heart rate variability to healthy longevity. The reason for this pattern lies in the way that averages work. People with lower HRV die… Continue reading People with high HRV live longer
Using HRV to reduce stress and improve training
The top athletes having been using HRV for the past couple of decades to improve their training to higher performance levels. Here’s how they do it. After putting in months of diligent base training, the racing season approaches. Most athletes follow a training plan. The basic training process isn’t complicated. Assessment: Ability and event demands;… Continue reading Using HRV to reduce stress and improve training
HRV and smoking
I am the guinea pig for many of the experiments that I’ve conducted with HRV. This one has been involuntary. While a number of countries, like the UK and New Zealand, are taking active steps to reduce smoking in the population, Switzerland is way behind. New Zealand is aiming to reduce smokers to 5% of the… Continue reading HRV and smoking
Stealing hope
A.L.S is a death sentence. Amyotrophic lateral sclerosis is a fatal type of motor neuron disease. It is characterized by progressive degeneration of nerve cells in the spinal cord and brain. It’s often called Lou Gehrig’s disease, after a famous baseball player who died from it[1]Amyotrophic Lateral Sclerosis (ALS). The muscles don’t get nutrition, and… Continue reading Stealing hope
Is America broke?
When evaluating a company, ratios provide profound insights into a company’s performance, it’s financial stability, and what its future holds. One of the key ratios is that between interest charges and cash flow. Anyone who has had a mortgage understands the problem. If your mortgage repayments represents a significant proportion of your disposable income, you’re… Continue reading Is America broke?
Modern medical myths
I have recently published a series of articles exposing how the arrogance of the medical fraternity caused deaths in the 19th century[1]Smallpox[2]How medical arrogance kills[3]John Snow and Cholera. Reading the articles, many people may think that today we have modern science making sure that these episodes are so much history. It’s not history. Ben Goldacre,… Continue reading Modern medical myths
John Snow and Cholera
As a child, John Snow showed an aptitude for mathematics and science and obtained a medical apprenticeship in 1827 at the age of 14. In 1831, the first cholera epidemic struck England, and Snow’s first encounter with the disease occurred in 1832. He treated many victims of the disease during this outbreak and became very… Continue reading John Snow and Cholera
