NOTE

Heart Rate Variability is a Measure of Resource Allocation in the Body

Alcohol consumption redirects resources to the liver, decreasing heart rate variability (HRV) as the body prioritizes detoxification. HRV reflects the availability of resources for allocation, with high HRV indicating abundant resources and low HRV indicating limited availability. During sickness, the immune system monopolizes resources, reducing HRV. Conversely, HRV increases after cooling down or completing digestion, freeing up resources. HRV fluctuates daily based on resource demands.
