HRV, or heart rate variability, is a measure of the variation in time between each heartbeat. A higher HRV is generally considered to be better because it indicates that the body’s nervous system is functioning properly and is able to respond to changes in the body’s needs. A lower HRV, on the other hand, can be a sign of poor health or increased stress.

There are several ways to increase HRV, including regular physical activity, getting enough sleep, managing stress, and eating a healthy diet. Some people may also find that practicing deep breathing or meditation can help to increase their HRV.

As for longevity and health, a higher HRV has been associated with a lower risk of heart disease and other health problems. However, more research is needed to fully understand the link between HRV and longevity. It is important to note that HRV is just one factor that can affect a person’s health and lifespan, and it is not the only thing that should be considered when trying to improve health and longevity.
