Whiskey is a dark-grain alcohol made all over the world. It was first developed in medieval Scotland and Ireland. In Gaelic, its name loosely translates to “water of life.”
In 16th-century Scotland, apothecaries sold whiskey as a tonic to slow aging, cure congestion, and relieve joint pain. During American Prohibition, doctors prescribed whiskey to treat pneumonia, high blood pressure, and tuberculosis.
Today, whiskey is available by different names based on its production — like single malt, scotch, bourbon, and rye. While these days it’s more likely to be listed on a bar tab than on a prescription pad, modern research has found evidence that may support some traditional claims that whiskey boosts health.
To reduce the risk of alcohol-related harms, the CDC's 2020-2025 Dietary Guidelines for Americans recommends that adults of legal drinking age can choose not to drink, or to drink in moderation by limiting intake to 2 drinks or less in a day for men or 1 drink or less in a day for women, on days when alcohol is consumed. The Guidelines also do not recommend that individuals who do not drink alcohol start drinking for any reason and that if adults of legal drinking age choose to drink alcoholic beverages, drinking less is better for health than drinking more.

Potential Health Benefits of Whiskey
Research suggests that there are other health benefits to drinking whiskey. However, these benefits are all associated with moderate consumption — heavy drinking can lead to serious health issues.
A glass of whiskey a day may offer health benefits like:
Whiskey has high levels of polyphenols, plant-based antioxidants linked with lowering your risk of heart disease. The polyphenols in whiskey have been shown to decrease “bad” cholesterol (LDL) and increase “good” cholesterol (HDL) levels, and reduce triglycerides, or fat in your blood.
Relief of Cold Symptoms
Whiskey can temporarily widen your blood vessels. In small amounts, this can help clear mucus congestion in your sinuses and chest, which lets your body better deal with sickness and infection. This effect may also relieve other symptoms of a cold or flu, like coughing or wheezing.
Immune System Support
Scientists are unsure why, but several studies link moderate alcohol consumption to improved immunity of diseases and improved responses to vaccines. Studies show lower rates of the common cold, faster removal of bacteria, and better antibody response in people who have a daily drink compared to those who don’t. However, much more research is needed to understand this effect.
The plant-based antioxidants in whiskey may help maintain a healthy chemical balance in your brain. Research shows small amounts of whiskey — especially aged varieties — increases our activity in the brain’s GABA neurotransmitter, responsible for things like nervous system function and memory.
One study found that people who consumed one to six drinks weekly had a lower risk of dementia than non-drinkers. Another showed that moderate alcohol intake might reduce cognitive decline in people with Alzheimer’s Disease.
Potential Risks of Whiskey
Whiskey’s potential health benefits are associated with low to moderate amounts. Over time, high alcohol consumption can increase your risk of chronic disease and other health issues.
Talk to your doctor to make sure alcohol is safe for you, and consider the following health risks:
Whiskey's heart benefits come with small doses. Heavy alcohol use can lead to high blood pressure, high cholesterol, and heart disease.
Mental and Cognitive Health
While low amounts may support brain health, in excess, studies show alcohol can disrupt how memories form. Over time, this can lead to cognitive decline.
Because your liver breaks down alcohol in your body, heavy drinking can lead to liver disease. High amounts of alcohol cause fatty deposits in your liver and scarring, which can eventually cause liver failure.
Immune System Function
High amounts of alcohol can weaken your immune system, reducing your body’s ability to fight off infection and raising your risk of chronic diseases.
While whiskey contains many health-boosting antioxidants, other foods — like fruits and vegetables — have similar or higher levels, but with more nutrition and fewer health risks.
