Observational trials suggest that alcohol consumption also raises the risk of specific subtypes of breast cancer that respond to these hormones. For example, randomized controlled trials show that alcohol consumption raises levels of sex steroid hormones in the blood. Such nuance is rarely captured in broader conversations about alcohol research—or even in observational studies, as researchers don’t always ask about drinking patterns, focusing instead on total consumption. Observational studies can still yield useful information, but they also require researchers to gather data about when and how the alcohol is consumed, since alcohol’s effect on health depends heavily on drinking patterns. And heavy drinking is unequivocally harmful to health. Steatotic liver disease develops in about 90% of people who drink more than 1.5 to 2 ounces of alcohol per day.

Overhydration sometimes occurs among athletes and outdoor laborers, but it can also be a sign of disease or damage to the hypothalamus. Some desert insects, such as Onymacris unguicularis, have evolved to drink substantially from nighttime fog.
To date, federal agencies like the National Institutes of Health have shown no interest in exclusively funding these studies on alcohol. Medicine and public health would benefit greatly if better data were available to offer more conclusive guidance about alcohol. Instead, much alcohol research is observational, meaning it follows large groups of drinkers and abstainers over time.

The less alcohol you drink, the lower your risk for these health effects, including several types of cancer. Similarly, in randomized trials, alcohol consumption lowers average blood sugar levels.
Excessive alcohol use
Current research points to health risks even at low amounts of alcohol consumption, regardless of beverage type. The term “drinking” is often used metonymically for the consumption of alcoholic beverages. Evidence-based hydration experts say that the amount of drinking water needed depends on ambient temperature, activity level, body size, and sweat rate. Lack of hydration causes thirst, a desire to drink which is regulated by the hypothalamus in response to subtle changes in the body’s electrolyte levels and blood volume. It’s tempting to assume that because heavy alcohol consumption is very bad, lesser amounts must be at least a little bad.
