What Causes Dermatitis and How to Avoid It

Dermatitis is a common skin condition characterized by inflammation and irritation of the skin. Numerous things, including as irritants, allergies, the environment, and even stress, might contribute to it. Understanding the causes of dermatitis is crucial for effectively managing and preventing flare-ups. 

In this blog post, we will explore common causes of dermatitis and provide practical tips on how to avoid them. By adopting preventive measures and making lifestyle adjustments, you can minimize the occurrence of dermatitis and promote healthier, happier skin. Let’s delve into the causes and prevention strategies for dermatitis.


Irritants are one of the primary causes of dermatitis. Exposure to harsh chemicals, detergents, soaps, solvents, or even prolonged contact with water can irritate the skin. To avoid irritant-induced dermatitis, opt for mild, fragrance-free products that are less likely to trigger a reaction. 

When handling irritants, such as cleaning products or chemicals, wear protective gloves to minimize direct contact. Additionally, after exposure to irritants, make sure to rinse your skin thoroughly and moisturize to restore the skin’s natural barrier.


Allergic contact dermatitis occurs when the skin comes into contact with substances to which an individual is allergic. Common allergens include certain metals (such as nickel), cosmetics, fragrances, latex, and certain plants. To avoid allergen-induced dermatitis, it is important to identify your specific allergens through patch testing conducted by a dermatologist. 

Once identified, diligently read product labels and avoid products that contain your known allergens. Opt for hypoallergenic and fragrance-free products, and consider using alternative materials, such as nickel-free jewelry or latex-free gloves.

Environmental factors

Environmental factors can significantly impact the occurrence of dermatitis. Extreme temperatures, dry air, low humidity, and exposure to sunlight can exacerbate symptoms. To minimize the impact of these factors, use humidifiers in dry environments to increase moisture levels. 

Protect your skin from cold and windy weather by wearing appropriate clothing and using moisturizers to combat dryness. Avoid overheating or excessive sweating, as it can worsen symptoms. When outdoors, apply a broad-spectrum sunscreen to shield your skin from harmful UV rays. Being mindful of your environment and taking appropriate precautions can help prevent dermatitis flare-ups.

Allergenic foods 

In some cases, certain foods can trigger dermatitis, especially in individuals with food allergies or sensitivities. Common culprits include dairy products, eggs, nuts, soy, and gluten. If you suspect that certain foods are contributing to your dermatitis, consider keeping a food diary to track any patterns or reactions. 

Consult with an allergist or dermatologist to undergo specific allergy testing. Once you identify the allergenic foods, avoid consuming them and seek alternative options that are safe for you. A well-balanced diet with nutrient-rich foods can support overall skin health and minimize the risk of dermatitis flare-ups.

Clothing and fabrics 

The choice of clothing and fabrics can impact dermatitis. Rough or irritating fabrics like wool or synthetic materials can cause friction and worsen skin irritation. Opt for soft, breathable fabrics like cotton or bamboo, which are less likely to irritate the skin. 

Before wearing new clothing, wash it to remove any potential irritants or chemicals used during manufacturing. Avoid using fabric softeners or harsh laundry detergents that can leave residue on clothing. Additionally, consider wearing loose-fitting clothing to allow the skin to breathe and minimize friction against sensitive areas.


Stress has a significant impact on our overall well-being, including our skin health. It can exacerbate dermatitis symptoms and trigger flare-ups. To manage stress and reduce its impact on dermatitis, use stress-reduction methods like yoga, deep breathing exercises, meditation, and indulging in your favorite pastimes.

Adequate sleep, regular exercise, and maintaining a healthy lifestyle can also contribute to stress reduction. If necessary, seek professional support from a therapist or counselor who can provide guidance and coping strategies to effectively manage stress levels.

Poor skincare routine 

A poor skincare routine can disrupt the skin’s natural barrier and increase the risk of dermatitis. Harsh cleansers, excessive scrubbing, or using abrasive exfoliants can irritate the skin and worsen symptoms. Opt for gentle cleansers that are specifically formulated for sensitive skin. 

Avoid hot water, as it can strip the skin of its natural oils and cause dryness. After cleansing, pat your skin dry instead of rubbing it with a towel. Follow up with a moisturizer suitable for your skin type to maintain adequate hydration. A consistent and gentle skincare routine can help protect the skin’s barrier and prevent dermatitis flare-ups.


Skin infections, such as fungal or bacterial infections, can complicate dermatitis or trigger flare-ups. It is essential to maintain good hygiene practices to minimize the risk of infection. Keep your skin clean and dry, especially in areas prone to sweating or moisture buildup. 

Avoid sharing personal items like towels, clothing, or grooming tools that can spread infections. If you suspect an infection, seek prompt medical attention for appropriate diagnosis and treatment. By preventing and treating infections, you can effectively manage dermatitis and reduce its impact on your skin.


Dermatitis can significantly affect the quality of life, but by understanding its causes and taking preventive measures, you can minimize its occurrence. Avoiding irritants and allergens, managing environmental factors, adopting a healthy lifestyle, and practicing good skincare habits are key to preventing and managing dermatitis. Consult with a dermatologist for personalized advice and recommendations tailored to your specific needs to ensure optimal skin health.
