8. Regulation in human health

Alcohol

Alcohol with a single but not systematic intake in small doses causes a slight increase, in moderation doses – a decrease in TP of HRV with a simultaneous rise in VLF and HF and a significant increase only VLF. In non-drinkers, an hour after taking alcohol, changes in HRV are more significant than in those who regularly take alcohol. In general, alcohol affects all parts of the regulation. The increase in HR under the influence of alcohol is due to a decrease in the high-frequency component of the HRV spectrum.
In alcohol, the well-known saying “everything is medicine, and everything is poison” finds a concentrated expression.
