Longevity doctor shares what alcohol does to health and how to optimise drinking for longevity
There is no safe limit for alcohol consumption when it comes to longevity healthcare. However, one drink does not ruin it all, explains Dr Vass.
When we refer to alcohol as our “poison of choice,” we might be closer to the truth than we realise. The effects of alcohol on human health have been under study since time immemorial. However, not everyone is updated on the latest findings.

Taking to Instagram on March 31, Dr Vassily Eliopoulos, a longevity expert trained at Cornell University and co-founder and chief medical officer of Longevity Health, shared some of them, highlighting their impact on longevity healthcare.
“This isn't about telling you to stop drinking. It's about giving you the data your doctor never did,” he explained. “Because the research on alcohol and ageing has shifted significantly, and most people are still operating on decade-old assumptions.”
Debunking the wine myth
It is popularly believed that a glass of red wine a day is good for health. While the narrative has dominated conversations on alcohol for years, it has been debunked by modern research, shared Dr Vass.
The claim was originally made based on observational studies that did not account for the fact that moderate drinkers also tended to be wealthier, more social, and more health-conscious across the board.
“The wine wasn't the variable. The lifestyle was,” noted Dr Vass.
Effect of alcohol on sleep
According to Dr Vass, sleep is where the damage due to alcohol consumption is most immediate and most underestimated.
“Alcohol feels like a sleep aid. It isn't,” he explained. “It suppresses REM sleep and slow-wave deep sleep, the stages where your brain clears metabolic waste, consolidates memory, and regulates cortisol.”
Two drinks before bed can reduce sleep quality by up to 24 percent, even if the individual does not wake up mid-sleep. Poor sleep leads to elevated cortisol levels and accelerated cellular ageing.
Effect of alcohol on hormones
Regular consumption of alcohol significantly impacts the endocrine system. This includes:
- Directly suppressing testosterone production, even at moderate intake
- Elevating estrogen conversion via aromatase activation
- Disrupting growth hormone release during sleep
- Raising baseline cortisol
“For a man in his 40s already experiencing natural hormonal decline, alcohol is quietly accelerating the process,” cautioned Dr Vass.
Alcohol as a cause of inflammation and cellular ageing
Alcohol metabolises into acetaldehyde, a compound that has the following effects:
- Damages DNA directly
- Triggers systemic inflammatory response
- Depletes NAD+, the molecule your cells need for energy production and repair
- Shortens telomeres over time with chronic use
“None of this shows up on a standard blood panel after a night out. But it compounds over the years, and it shows up in biological age testing,” noted Dr Vass.
How to safely consume alcohol
The first thing to keep in mind is that the latest research shows that there is no safe limit for alcohol consumption when longevity optimisation is concerned.
“That doesn't mean one drink ruins everything,” stated Dr Vass. “It means the dose-response curve is real and the impacts on sleep, hormones, and inflammation start at lower levels than most people assume.”
He went on to share the following drinking tips to keep in mind:
- Avoid alcohol within three hours of sleep, non-negotiable for sleep quality
- Track HRV (heart rate variability) the morning after drinking
- Consider a 30-day elimination as a diagnostic, not a lifestyle sentence
- If drinking, prioritise recovery: hydration, quality sleep, next-day movement
