In this short explanatory segment, the speaker describes how the body processes alcohol and why a hangover can leave you feeling exhausted. When alcohol is consumed, it is metabolized into acetaldehyde, a toxin that is far more harmful than ethanol itself. The co‑enzyme NAD (nicotinamide adenine dinucleotide) is essential for converting acetaldehyde into less toxic substances and for clearing other harmful metabolites. As drinking continues, NAD is consumed faster than it can be replenished, leading to a depletion of this crucial molecule. The resulting NAD shortage impairs the body’s ability to detoxify, which manifests as classic hangover symptoms—low energy, difficulty getting out of bed, headaches, and overall fatigue.
