Eczema, also known as atopic dermatitis, is a common skin condition that affects millions of people worldwide. It is characterized by dry, itchy, and inflamed skin, which can be both uncomfortable and embarrassing for those who suffer from it.
While the exact cause of eczema is still unknown, researchers believe that a combination of genetic and environmental factors play a significant role in its development. In recent years, there has been increasing evidence suggesting a hidden connection between eczema and certain risk factors.
Understanding these risk factors can help individuals manage their eczema symptoms more effectively and possibly prevent its occurrence altogether.
1. Family History
If you have a family history of eczema, your chances of developing the condition are significantly higher. Studies have shown that certain genes are associated with an increased susceptibility to eczema.
If one or both of your parents have eczema, there is a greater likelihood that you will develop it as well. However, it’s important to note that having a family history of eczema does not guarantee its occurrence. Many individuals with no family history also develop eczema, suggesting that other risk factors are at play.
2. Allergies and Asthma
Eczema, allergies, and asthma are all part of a group of conditions known as the atopic triad. People who have one of these conditions are more likely to develop the others.
Research has found that individuals with eczema are at a higher risk of developing allergies and asthma later in life. The exact relationship between these conditions is complex and still not fully understood, but it’s believed that a shared genetic predisposition, as well as an abnormal immune response, may play a role.
3. Environmental Triggers
Various environmental factors can trigger or exacerbate eczema symptoms. These triggers may vary from person to person, but some common ones include exposure to harsh chemicals, certain fabrics, pet dander, pollen, and mold.
Additionally, extreme temperatures, humidity levels, and stress can also contribute to eczema flare-ups. Identifying and avoiding specific triggers can help individuals better manage their eczema and reduce its impact on their daily lives.
4. Irritants in Skincare Products
People with eczema often have sensitive skin that reacts negatively to certain skincare products. Harsh soaps, fragrances, dyes, and preservatives can all irritate the skin and trigger eczema flare-ups.
It’s important for individuals with eczema to choose skincare products specifically formulated for sensitive skin and free from potential irritants. Patch testing new products before applying them to larger areas of the skin is also recommended to avoid adverse reactions.
5. Stress and Emotional Factors
Stress and emotional factors can have a significant impact on eczema symptoms. It has been observed that stress and anxiety can worsen eczema flare-ups and increase the intensity of itching and inflammation.

In turn, the symptoms of eczema can also lead to increased stress and emotional distress. This cycle can be challenging to break, but incorporating stress management techniques such as meditation, exercise, and therapy can help reduce the impact of stress on eczema.
6. Climate and Seasonal Changes
Changes in climate and seasons can affect the severity of eczema symptoms. Dry and cold weather conditions can cause the skin to become more dehydrated, leading to increased itching and irritation.
On the other hand, hot and humid climates can cause excessive sweating, which can also trigger eczema flare-ups. Individuals with eczema should pay attention to the weather forecast and adjust their skincare routine accordingly to maintain optimal skin health.
7. Food Allergies and Sensitivities
While food allergies are not a direct cause of eczema, they can exacerbate symptoms in some individuals. Common allergenic foods such as dairy, eggs, nuts, soy, and wheat have been known to trigger eczema flare-ups in sensitive individuals.
It’s important to identify and avoid any specific food triggers that may be worsening eczema symptoms. Keeping a food diary and working with a healthcare professional can help pinpoint any dietary factors contributing to eczema.
8. Microbial Imbalance
The skin is home to a variety of microorganisms, including bacteria and fungi. Research suggests that an imbalance in the skin microbiome may play a role in the development and severity of eczema.
Disruptions in the delicate balance of microbes can lead to increased inflammation and skin barrier dysfunction. Probiotics, which are beneficial bacteria, have shown promise in managing eczema symptoms by restoring the skin’s microbial balance. However, more research is needed to fully understand the connection between microbial imbalances and eczema.
9. Occupational Hazards
Certain occupations may expose individuals to substances or conditions that can trigger or worsen eczema.
Healthcare workers, hairdressers, construction workers, and individuals in other professions that involve frequent exposure to water, chemicals, or irritants may be more prone to developing occupational eczema. Taking protective measures such as wearing gloves and using barrier creams can help reduce the risk of eczema in these work environments.
10. Age and Gender
Eczema can develop at any age, but it is most commonly diagnosed in early childhood. In many cases, eczema symptoms improve or disappear by adulthood. However, some individuals continue to experience eczema throughout their lives.
Studies have shown that males are more likely to develop eczema during childhood, while females are more prone to developing it later in life. The reasons for these age and gender differences in eczema prevalence are still not fully understood, and further research is needed to elucidate these patterns.
