  • More people are measuring their heart-rate variability and seeing those HRV numbers plummet after a few drinks the night before.

The article from MSN discusses how alcohol consumption negatively impacts heart rate variability (HRV) and sleep quality. Alcohol, while often used as a sleep aid, actually disrupts the sleep cycle, particularly by reducing REM sleep, which is crucial for restorative rest. This leads to less restful sleep and can contribute to feelings of fatigue and grogginess the next day. Moreover, alcohol decreases HRV, which is an indicator of the body's ability to adapt to stress and maintain health. A lower HRV is linked to poorer cardiovascular health and increased stress levels. The article explains that while alcohol might initially make one feel relaxed, its overall effect on the body's autonomic functions like heart rate and sleep architecture is detrimental, potentially leading to long-term health issues if consumption is regular or excessive.
