Knocking back a cocktail is one of the most time-honored ways to chill after a stressful day of work. The reason? Alcohol, including rum, acts as a depressant that dampens the central nervous system. In other words, it’s a sedative.
In addition to its warming, calming qualities, rum is rich in antimicrobial properties that can help knock out the common cold. The British Army was actually known to give its sailors the drink for preventing scurvy (a disease caused by vitamin C deficiency); it was the lime in the rum that did the trick, but we still say bottoms up to a rum toddy for a nightcap.
