Why Dry January Could Be the Perfect Reset for Your Gut and Skin

As the New Year begins, many of us feel the need to reset after the indulgences of the festive season. One increasingly popular way to do this is by embracing Dry January, a commitment to avoiding alcohol for the entire month. This isn’t just about saying no to your favourite drink—it’s an opportunity to reset your gut and skin health, especially if you’re mindful of sugar intake at the same time.
​
As a Registered Nutritional Therapist specialising in gut and skin health, I’ve seen first-hand how alcohol and sugar impact the body, and how a break can lead to dramatic improvements.
Let’s explore why Dry January could be the best thing you do for your health this year and how to make the most of it.

Alcohol and Gut Health: Why Your Gut Deserves a Break

Your gut plays a foundational role in your overall health, acting as home to trillions of bacteria and other microorganisms collectively known as the gut microbiome. These microorganisms are essential for digestion, immunity, hormone regulation, and even mental health. However, alcohol disrupts this delicate balance in several ways, particularly when consumed in excess.
​
Alcohol contributes to an imbalance in the microbiome, often referred to as dysbiosis, by feeding harmful bacteria while suppressing beneficial microbes. This disruption can cause digestive discomfort, bloating, and inflammation. Alcohol also damages the lining of the gut, increasing its permeability. This condition, often called "leaky gut syndrome," allows toxins, bacteria, and undigested food particles to pass into the bloodstream, triggering widespread inflammation. Over time, this inflammatory state can contribute to chronic health issues, including autoimmune conditions and skin problems like eczema.

Additionally, alcohol promotes the overgrowth of yeast, such as Candida albicans. When levels of Candida rise unchecked, symptoms such as fatigue, brain fog, and digestive issues can occur. This imbalance in the gut can also exacerbate skin conditions. By stepping away from alcohol during Dry January, you give your gut the chance to heal. Beneficial bacteria can begin to thrive again, the gut lining can repair itself, and inflammation can subside, paving the way for improved digestion and overall wellbeing.

Alcohol and Skin Health: A Visible Transformation

The impact of alcohol isn’t limited to your gut; it also takes a toll on your skin. Alcohol dehydrates the body, stripping your skin of the moisture and nutrients it needs to remain healthy and resilient. This can lead to dry, flaky skin that looks dull and lacks elasticity.

Chronic alcohol consumption also accelerates the ageing process by reducing collagen production and increasing oxidative stress. Collagen is a vital protein that keeps skin firm and youthful, and its depletion leads to the early onset of fine lines and wrinkles. Additionally, alcohol depletes the body of essential nutrients, such as vitamin A, vitamin C, and zinc, which are critical for skin repair and maintenance.
​
For those with sensitive or reactive skin, alcohol can exacerbate existing conditions such as rosacea, eczema, and psoriasis. Its inflammatory effects often manifest as redness, puffiness, and breakouts.
The good news is that within weeks of giving up alcohol, many people notice significant improvements in their skin. Increased hydration and reduced inflammation allow the skin to recover, revealing a healthier, more radiant complexion.

Alcohol and Dermatitis

For individuals dealing with dermatitis, including eczema, seborrheic dermatitis, or contact dermatitis, alcohol and sugar can be particularly problematic. Both substances act as triggers that can worsen symptoms or interfere with the healing process.

Alcohol contributes to inflammation, a key driver of dermatitis flare-ups. It also dehydrates the body, leaving the skin more vulnerable to irritants and less able to retain moisture—a critical factor for managing dermatitis. Additionally, alcohol’s impact on gut health can worsen skin conditions. The gut and skin are intricately linked through the gut-skin axis, and alcohol-induced gut dysbiosis can increase inflammatory markers that trigger dermatitis.
​
By removing alcohol and reducing sugar intake during Dry January, you provide your skin with the opportunity to calm down, rebuild its barrier function, and repair itself. Many individuals with dermatitis report fewer flare-ups, less itching, and healthier skin when they eliminate these two triggers.

The Role of Sugar in Gut and Skin Health

Sugar plays a significant role in gut and skin health and is often a hidden problem in many diets. High sugar intake disrupts the balance of the gut microbiome by feeding harmful bacteria and yeasts, leading to dysbiosis. It also reduces the diversity of gut bacteria, which is a key marker of good gut health.
​
In the skin, sugar triggers a process known as glycation, where sugar molecules bind to proteins like collagen and elastin. This weakens these vital proteins, causing the skin to lose its elasticity and firmness, leading to sagging and wrinkles. Sugar can also exacerbate acne and oily skin by spiking insulin levels, which in turn stimulate the production of androgens—hormones that increase oil production.

Hidden Sugar in Drinks: What You Need to Know

Many alcoholic drinks are packed with hidden sugars, which can undermine your efforts to improve your health. For example, a margarita contains around 13g of sugar, while a piña colada can pack a staggering 32g, more than a can of coke.

Sweet wines, such as dessert wines, contain 8-10g of sugar per small glass, while even a pint of lager may have 1-2g. Spirits mixed with tonics or sugary sodas can add 15-20g of sugar per drink.

Even non-alcoholic options, such as mocktails, can contain significant amounts of sugar if made with syrups or fruit juices. A virgin mojito, for instance, may have over 20g of sugar.

That said, mocktails are still preferable to alcoholic cocktails as they avoid alcohol’s inflammatory effects.
​
Over time, many people find that they no longer crave sugary or alcohol-like replacements, preferring instead to sip on sparkling water with a splash of fresh fruit juice or herbal teas.

How Dry January Supports Your Gut and Skin Health

​By removing alcohol and reducing sugar, Dry January offers a powerful reset for your gut and skin. As your microbiome begins to rebalance and inflammation decreases, you may notice better digestion, reduced bloating, and clearer, calmer skin. The reduction in dehydration and oxidative stress also allows your body to repair itself more effectively, leaving you feeling energised and looking refreshed.

Practical Tips for a Successful Dry January

To maximise the benefits of Dry January, focus on hydration, nutrition, and gut health. Drink plenty of water, and consider adding lemon, cucumber, or mint for variety. Prioritise whole foods, including fresh vegetables, lean proteins, healthy fats, and fermented foods like kimchi, sauerkraut, or live yoghurt to support your gut microbiome.
​
Keep track of how you feel throughout the month, noting improvements in your digestion, energy, and skin.
