Today is a long-overdue podcast, but I wanted to make sure that I got a great expert on the topic, and then I discovered Dr Torkil Faero, who wrote a great book called The Pulse Cure.

What if you could see the toll that over-work, too much sugar or bad sleep really take on your system, knew what boosts your energy, and what saps it, and when you are heading for burnout? What if you could feel more vitality and joy, have stronger will power and live longer?

With the aid of your phone, smartwatch or a wearable heart rate monitor and The Pulse Cure, you can. The key lies in measuring your heart rate variability - the distance between your heart beats - which indicates what is happening in your autonomic nervous system. Tuning into your heart rate variability can show you how your personal constitution reacts to specific stressors and help you tailor what you need to do to recharge.
