                                The human body metabolizes alcohol at a remarkably constant rate, a process primarily carried out by the liver. For most people, blood alcohol concentration (BAC) decreases by approximately 0.015% to 0.020% per hour, and this rate cannot be substantially increased by external factors like coffee or cold showers.
