True of false low BAL will always cause a hangover?

False. A low blood alcohol level (BAL) does not always cause a hangover; hangovers are influenced by various factors, including the type and amount of alcohol consumed, individual tolerance, hydration levels, and overall health. While higher BALs are more commonly associated with hangovers, some people may experience hangover symptoms even after consuming small amounts of alcohol. Each individual's response to alcohol can vary significantly.
