As people grow older, they may find that even one or two drinks have a stronger effect than they did when they were younger. This is due to natural changes in the body that make it more sensitive to alcohol and reduce the ability to tolerate it. Recent research has shown that alcohol consumption among people aged 65 and older has been increasing, especially as life expectancy rises and the number of older adults grows. The body's composition changes as we age, with more body fat and less water. A 2023 study published in the journal Kidney Research and Clinical Practice noted that the body's water content decreases with age. This is important because alcohol dissolves in water, so the same amount of alcohol can lead to higher concentrations in the bloodstream in older individuals, causing more immediate effects. Women tend to be more sensitive to alcohol than men, partly because they have less water in their bodies and fewer enzymes that break down alcohol. These enzymes, including alcohol dehydrogenase, aldehyde dehydrogenase, and cytochrome P450 2E1, become less active with age, leading to alcohol being processed more slowly and staying in the system longer. As people age, their brains also become more sensitive to alcohol’s effects, which can increase the risk of problems with balance and coordination, potentially leading to falls. Alcohol can also impair judgment, reaction time, and the ability to drive safely. Additionally, older adults often take more medications, and many of these can interact with alcohol, either reducing their effectiveness or causing side effects like drowsiness or stomach bleeding. Regular alcohol consumption can lead to various health problems, including worsening depression, raising blood pressure, and causing irregular heartbeats. It can also disrupt sleep patterns, reducing the quality of sleep, which is already a concern for older adults. Long-term drinking increases the risk of chronic conditions such as liver disease, head and neck cancer, and cognitive decline. Experts suggest that older adults should carefully consider the risks and benefits of drinking alcohol, taking into account their health and medication use. Some recommend adjusting guidelines for moderate drinking, possibly limiting it to one drink per day after the age of 65. Drinking with food can slow alcohol absorption, and alternating alcoholic drinks with non-alcoholic ones can help maintain hydration.
