International Women’s Day 2025’s theme, #AccelerateAction, highlights the need for urgent steps toward gender equality—including health and safety awareness. One key area where knowledge can drive action is alcohol consumption and its unique effects on women.
Many people assume that alcohol affects everyone the same way, but biological differences mean that women process alcohol differently than men. These differences can lead to higher blood alcohol concentration (BAC) levels, increased health risks, and greater vulnerability to alcohol-related harm.
Understanding these effects can help women make informed choices about drinking, driving, and personal safety.
Why alcohol affects women differently
Women experience the effects of alcohol differently due to biological and physiological differences. Even when drinking the same amount as men, women tend to have higher BAC levels because of the following reasons:
- Lower body water percentage – Women naturally have less body water than men, meaning alcohol remains more concentrated in the bloodstream.
- Enzyme differences – Women produce less alcohol dehydrogenase (ADH), the enzyme that breaks down alcohol in the stomach. As a result, more alcohol enters the bloodstream before it can be metabolised.
- Hormonal fluctuations – Estrogen can affect how alcohol is processed, making its effects more pronounced at certain times in the menstrual cycle.
- Body composition – Higher body fat percentage slows alcohol metabolism, causing alcohol to stay in the system longer.

The impact of alcohol on women’s health
Because alcohol stays in a woman’s system longer and at higher concentrations, it can contribute to increased short- and long-term health risks:
- Stronger and quicker intoxication – Women often feel the effects of alcohol more intensely and for longer periods.
- More severe hangovers – Due to slower alcohol breakdown, women may experience longer-lasting hangovers.
- Higher risk of alcohol-related illnesses – Women are more vulnerable to liver disease, heart disease, and certain cancers from prolonged alcohol consumption.
- Increased risk of harm – Women face higher risks of alcohol-related violence, drink spiking, and assault.
Alcohol, driving, and safety risks for women
Women’s bodies metabolise alcohol differently, leading to higher BAC levels and longer impairment, increasing the risk of DUI offences and accidents. Understanding these risks can help women make safer decisions when it comes to drinking and driving.
- Morning-after risk – Many women unknowingly drive the next morning while still over the legal BAC limit due to their slower alcohol metabolism. This increases the risk of DUI penalties or accidents.
- Hangover driving is dangerous – Even when BAC has dropped below legal limits, reaction time, focus, and cognitive function remain impaired.
- Personal breathalysers – A personal breathalyser allows women to self-check BAC levels before driving, ensuring they are legally and physically safe to be behind the wheel.

How women can make safer choices when drinking
Taking proactive steps can help reduce risks and improve safety when drinking:
- Know your limits – Understand that alcohol affects you differently than it does men.
- Use a personal breathalyser – Ensure you’re safe to drive by checking your BAC before getting behind the wheel.
- Stay hydrated & eat before drinking – Helps slow alcohol absorption and reduce intoxication effects.
- Be aware of drink spiking risks – Never leave drinks unattended and stick with trusted friends in social settings.
- Plan a safe way home – Use a designated driver, taxi, or rideshare service if unsure of BAC levels.
