Drinking alcohol while having a cold is generally not recommended. Alcohol can weaken the immune system, prolong the sickness, worsen symptoms like congestion, headaches, and nausea, and can also cause dehydration which makes symptoms worse. Additionally, alcohol can interact negatively with common cold medications, increasing the risk of side effects or liver damage if combined with drugs like acetaminophen. For these reasons, it's best to avoid alcohol until fully recovered from a cold.
