Everyone says ageing is inevitable. Some of what gets filed under age is stress load – and your smartwatch may already be measuring it.
HRV, heart rate variability, tracks the small changes in time between heartbeats. Under pressure, it tends to fall. As you recover, it tends to rise.
So what is a good HRV by age? It tends to fall as we get older and varies widely from person to person – so the useful reading is your own trend across a few weeks. A single morning says very little.
It is a free readout of where you’re heading – and it moves when the load you carry changes.
Do you track HRV – yes or no?
