It may make you more susceptible to viruses.
While alcohol may make you feel sleepy, it can actually reduce the amount of quality sleep you get each night. According to a 2018 study published in JMIR Mental Health, individuals with low alcohol consumption reduced their sleep-induced physiological recovery by 9.3%, individuals with moderate alcohol consumption reduced recovery by 24%, and those with high alcohol intakes—more than one drink a day for women or more than two drinks per day for men—reduced recovery by 39.2%.
Unfortunately, over time, this can lead to serious immune health issues. A 2017 study conducted by researchers in the University of Washington Health Sciences department and UW Medicine found that, among 11 pairs of identical twins, those who slept for fewer hours had a less robust immune system than those who slept more.

It could lower your risk of getting colds.
Though you may be more likely to develop certain viruses if you're a regular wine drinker, the common cold may not number among them. According to a 2012 retrospective study published in BMJ Public Health, among a group of 899 men, frequent alcohol consumption was associated with lower rates of developing the common cold compared to those who never drank.
It may make your flu symptoms worse.
If you're worried about getting the seasonal flu and how it might affect you, you might want to start limiting your alcohol consumption now. A 2014 study published in Alcoholism Clinical & Experimental Research found that chronic alcohol consumption can make influenza virus A infections worse due to alcohol's impairment of T cells that might otherwise boost a person's immune response.
It may make you less susceptible to autoimmune thyroid disease.
Your thyroid function has wide-ranging effects throughout your body, from influencing your weight to your energy levels throughout the day. Surprisingly enough, this vital gland may actually benefit from wine consumption—a 2012 study published in the European Thyroid Journal found that individuals in two separate studies who regularly consumed alcohol developed lower rates of autoimmune thyroid disease than members of the studies' control groups.
