You’ve probably heard that taking a break from alcohol can reset your health, but can just one month really make a difference? With Dry January gaining popularity, it’s time to separate fact from fiction. In this article, we tackle five common myths about short-term sobriety and reveal what the science says about the real impact of 30 alcohol-free days on your body and mind.
The idea of committing to a month without alcohol has rapidly grown in popularity since the conception of initiatives like Dry January and Sober October. First launched in 2013 with 4,000 participants, the Dry January scheme saw almost 9 million people in the UK planning to commit to an alcohol-free month a decade later in 20231.
In the long term, alcohol intake can negatively impact blood pressure and increase the risk of stroke, hypertension, cancer, and liver disease2. So, is one month of short-term sobriety really enough to impact your long-term health?
Myth 1 – “One Month Isn’t Long Enough to Matter”
One month is long enough to make a difference. Studies show health benefits to short-term sobriety that start within days to weeks. Alcohol abstinence for one month has been shown to significantly enhance sleep quality3, support weight loss4, and enhance overall well-being5.
The benefits of short-term abstinence are not just outwardly visible. One month of sobriety has also shown to:
- Decrease enzymes indicative of liver damage6.
- Lower blood pressure4.
- Improve insulin resistance4.
- Lower the abundance of cancer-related growth factors4.
This suggests that a short break from alcohol can lower the risk of liver disease, stroke, diabetes, and cancer.
In addition to reducing cumulative damage, a short-term break can also reset your relationship with alcohol. Over 17,000 people took part in Dry January 2014, and Public Health England reported that, for many, this break allowed them to not only drink less but also drink less frequently for months afterwards7.
Myth 2 – “If You’re Not a Heavy Drinker, It Won’t Make a Difference”
Even moderate drinking raises the risk of several cancers, particularly breast and bowel cancers, but also mouth, oesophagus, larynx, pharynx, and liver cancer. It is estimated that one in 10 breast cancer cases is caused by drinking alcohol8.
There are three main ways that alcohol increases the risk of cancer:
- Cell damage: Alcohol is converted to acetaldehyde in the body, a toxic compound that can damage cells as well as DNA9.
- Cell division: Cancer is characterised by uncontrolled and excessive cell division. Alcohol influences hormone levels and makes cells divide more often10.
- Harmful chemicals: Alcohol damages the protective layers between cells and tissues, making it easier for carcinogens from tobacco smoke or diet to move into the body and cause damage11,12.
Unfortunately, there is no “safe” level of alcohol when it comes to cancer risk, and all alcoholic drinks, no matter the type, increase the risk of cancer8.
Myth 3 – “You’ll Just Go Back to Old Habits Anyway”
Research from the University of Sussex shows that 70 per cent of people participating in Dry January drink less, even six months later, highlighting the long-term impact of one month sobriety13.
Changing drinking behaviour starts with awareness. Initiatives like Dry January create a clear psychological boundary that helps people notice how, when, and why they drink. The pause can break automatic habits and offer space to reflect on physical and emotional triggers, such as stress, fatigue, or social pressure, that drive alcohol cravings14.
Short-term sobriety also provides proof that alcohol is not needed to have fun, relax, or socialise. Aside from health benefits, 86 per cent of Dry January participants also report saving money, a further motivation to maintain lower-risk drinking patterns once January ends14.
Myth 4 – “It’s All or Nothing, You Have to Quit Forever”
Dry January is a health experiment, not a lifelong commitment. This is what makes the initiative approachable for many people.
Cutting down is still clearly beneficial. Fewer units and fewer heavy-drinking days reduce risks of high blood pressure, liver disease, cancer, poor sleep, and low mood4. The NHS emphasises cutting down on drinking, and encourages people to:
- Track units and set a limit
- Plan drink-free days
- Use low alcohol or alcohol-free alternatives
- Set a strict budget for alcohol
This promotes a sustainable way forward, instead of ‘all or nothing’ behaviour, which may not be realistic2,14. Aside from going teetotal, drinking in moderation and being mindful about how much and how often you drink is the best way to reduce adverse health consequences.
Myth 5 – “If You’re Healthy Now, There’s No Need to Worry”
Health is cumulative, and risks build slowly over time. The impact of alcohol on the body accumulates quietly over many years. There may be no obvious symptoms.
Evidence shows clear relationships between long-term drinking and conditions such as cancer, liver disease, and hypertension. This means small, repeated exposures gradually increase risk8,14.
Cumulative health damage may seem impossible to track, but it’s not. MRI scans, such as Ezra’s multi-organ MRI scan, offer a way to see what is happening beneath the surface. Structural changes, silent tumours, or organ damage can be revealed.
In the UK, proactive screening and early detection are central pillars of cancer and cardiovascular prevention. This is particularly important as diseases linked to alcohol consumption, such as coronary heart disease, stroke, and breast cancer, are among the top 10 causes of death in the UK15.
Finding problems early, before symptoms occur, greatly improves treatment options and prognosis, and allows proactive changes in lifestyle to be enacted before early warning signs progress into serious disease.
Conclusion: Short-Term Actions Can Influence Long-Term Health
One month without alcohol may not seem like a lot of time to make big changes, but short-term sobriety can lead to noticeable improvements in well-being and quality of life, long-term health benefits, and healthier drinking habits.
It’s never too early or too late to start investing in long-term health. Proactive actions, like eliminating alcohol, drinking mindfully, or having regular health checks, can help limit the adverse effects of alcohol and catch alcohol-associated diseases earlier.
