Many people choose to start a new year with a renewed focus on health and well-being.
One increasingly popular way to do this is by taking part in Dry January – an international campaign that encourages people to take a break from alcohol for 31 days.
First launched in 2013, Dry January offers a chance to reset your relationship with alcohol, especially after the Holidays, when drinking levels often increase.
Over a decade later, the campaign has grown into a well-recognized movement, with thousands of participants around the world, reporting improvements in sleep, energy, mood, and physical health.
Here, we explore what alcohol does to the body, alcohol consumption guidelines, the benefits of reducing alcohol intake, and tips for taking part in Dry January.
What happens to your body when you drink alcohol?
According to data from the 2024 National Survey on Drug Use and Health (NSDUH), about 21.7% of U.S. adults reported binge drinking at least once in the previous 30 days.
When alcohol is consumed, it is absorbed into the bloodstream and processed mainly by the liver. While the liver can metabolize small amounts efficiently, excessive or frequent drinking causes a build-up of toxins, which can have harmful effects across multiple organ systems.
Some of the ways alcohol affects the body include:
- Liver damage: The liver breaks down alcohol, but heavy or prolonged drinking can lead to fatty liver, alcoholic hepatitis, fibrosis, or cirrhosis – a serious condition involving permanent liver scarring.
- Brain function: Alcohol interferes with the brain’s communication pathways, impacting mood, behavior, coordination, and decision-making. Long-term use is associated with cognitive decline and increased risk of dependency.
- Heart health: Drinking too much alcohol raises blood pressure, weakens the heart muscle (cardiomyopathy), and increases the risk of heart attack and stroke.
- Digestive system: Alcohol irritates the stomach lining, contributing to acid reflux and inflammation. Over time, it can impair nutrient absorption and increase the risk of pancreatitis and ulcers.
- Cancer risk: Alcohol consumption is classified as a Group 1 carcinogen by the International Agency for Research on Cancer, and has been linked to several cancers, including mouth, throat, esophagus, liver, colon, and breast cancer.
- Mental health: Regular heavy drinking can worsen or contribute to conditions such as anxiety, depression, and sleep disorders.
Alcohol’s effects are dose-dependent, meaning the more you drink, and the more frequently you drink, the higher your risk of developing health problems.

Understanding low-risk alcohol guidelines
To support healthier drinking habits, the Centers for Disease Control and Prevention (CDC) provides low-risk alcohol consumption guidelines based on extensive research into the short- and long-term health risks associated with drinking alcohol.
These recommendations are intended to help people make informed decisions and reduce the risk of alcohol-related harm.
Current US low-risk alcohol guidelines
- Daily limits:
- Men are advised to consume no more than two standard drinks per day
- Women are advised to consume no more than one standard drink per day
- Weekly intake: While US guidelines focus on daily limits rather than a weekly total, regularly exceeding these amounts increases the risk of high blood pressure, liver disease, heart disease, and certain cancers.
- Avoid binge drinking: Drinking large amounts in a short period of time significantly increases the risk of injury, alcohol poisoning, and long-term health problems. Binge drinking is defined as:
- Five or more drinks on a single occasion for men
- Four or more drinks on a single occasion for women
It’s important to understand that no level of alcohol consumption is completely risk-free. For individuals with certain health conditions, those taking specific medications, or those who are pregnant or trying to conceive, not drinking alcohol at all is the safest option.
What is a standard drink in the US?
In the US, a standard drink contains approximately 14 grams of pure alcohol. This is equivalent to:
- 12 ounces of regular beer (about 5% ABV)
- 5 ounces of wine (about 12% ABV)
- 1.5 ounces of distilled spirits (about 40% ABV)
Because alcohol strength and serving sizes can vary widely, particularly with craft beers, large wine pours, or mixed drinks, it’s easy to consume more alcohol than intended without realizing.
What are the benefits of cutting back on alcohol?
Whether you’re taking part in Dry January or simply aiming to reduce your intake, cutting back on alcohol can lead to significant improvements in your physical and mental health, often within just a few weeks.
Here are some key benefits:
- Improved liver health
Reducing or stopping alcohol consumption gives the liver a chance to repair itself and reduces the risk of long-term liver disease. - Better mental well-being
Alcohol is a depressant and can worsen anxiety, low mood, and irritability. Many people notice improved mental clarity, mood stability, and resilience after reducing their intake. - Deeper, more restorative sleep
While alcohol might make it easier to fall asleep, it disrupts REM (deep) sleep stages, leaving you feeling groggy the next day. Cutting back can lead to more restful and energizing sleep. - Weight loss and improved digestion
Alcohol contains hidden calories and sugars that contribute to weight gain. Reducing intake may support weight loss and improve digestive function, including reduced bloating and acid reflux. - Lower risk of serious health conditions
Reducing alcohol consumption decreases your risk of serious conditions such as high blood pressure, stroke, heart disease, liver disease, and several forms of cancer. - Increased energy and focus
Without the dehydrating and sedating effects of alcohol, many people experience a noticeable boost in energy levels and concentration. - Financial savings
Alcohol can be expensive. Cutting back, even for a month, can lead to noticeable savings.
Taking a break from alcohol, even temporarily, can offer a valuable opportunity to reassess your habits and experience how your body and mind respond without regular alcohol use.
Please note: if you are struggling with alcohol addiction, reducing your alcohol intake without medical advice might not be right for you. It is strongly recommended that you speak to your physician or healthcare provider, who will be able to provide advice on reducing alcohol intake safely.
