The Most Common Causes Of Eczema Flare-ups

While we don’t know the cause of eczema, research indicates it is caused by a combination of genetic factors and triggers. People with eczema may have an overactive immune system. While anyone’s skin can become irritated by factors like cold weather or sweat, those with eczema are affected more dramatically.  

There is no cure for eczema, but there are many treatment options to relieve eczema symptoms. One of the most effective means of managing eczema is identifying your triggers. Below, we will go over the most common triggers and how to cope with them.

Your Diet

Certain foods can trigger eczema flare-ups for many sufferers. Everyone’s body is different, so there is no single type of food to avoid if you have eczema.

However, many people seem to be triggered by sugar, refined carbohydrates, gluten, red meat, and dairy products. Also, anything you are allergic to can cause eczema flare-ups – even if you only ingest it in small amounts.

Causes of Eczema Flare-ups

The best means to handle dietary flare-ups is to simply avoid the foods in question. To identify potential culprits in your diet, try keeping a food diary and notice if flare-ups happen after you eat a certain food.

The Weather

Cold air in particular is harsh on dry skin, and air tends to get much dryer in the winter. For many, the cooler months can cause eczema flare-ups, but it isn’t just lower temperatures that can irritate your skin. Warm weather can cause excessive sweat, leading to flare-ups, and even sudden fluctuations in weather can affect your skin if it’s very sensitive.

You cannot entirely control the weather, but you can be aware of any seasonal changes that affect your skin and give your skin extra care as a precaution. For example, if you know rainy conditions trigger flare-ups, be more vigilant about moisturizing during rainier months.

There are many over-the-counter moisturizers designed for eczema. The most effective option is Delfina Dry Skin Oil. 

Delfina works by penetrating the outer layers of skin and stimulating hydration. You can read more about how Delfina works here and read patient success stories here.



Almost anyone with sensitive skin will react poorly to things like cigarette soap, lotions with fragrances, and certain fabrics. If you have eczema, you are even more likely to be adversely affected by common irritants.

Anything – from laundry detergent to lotion – can be an irritant. Everyone’s skin is different. Much like identifying your dietary triggers, it can help to pay attention to the products you use on a daily basis to see if you notice a pattern.

When it comes to irritants, the best defense is a good offense. If you suspect a product you use causes eczema flare-ups, cease use immediately.


Excessive sweat after a heavy workout can cause anyone to develop a skin rash. If you have eczema, you’re even more at risk for an adverse reaction to intense physical activity.

If you notice flare-ups after a workout, you do not need to halt your gym routine altogether. However, take steps to be gentle on your skin during and after exercise.

Wear light-fitting clothing and moisturize your skin after workouts. Delfina Dry Skin Oil is again your best option. In fact, many people whose eczema was specifically triggered by their workout routine found relief with Delfina.

Stress and Anxiety

Stress and anxiety can exacerbate many different skin conditions including eczema. Any sort of emotional stress can impact your immune system and, in turn, your body’s ability to suppress flare-ups.

You cannot entirely avoid stress or anxiety, but you can take steps to reduce your stress overall. Activities like yoga and meditation can help you manage stressful situations. A regular exercise routine helps with emotional regulation overall.

Also, take stock of what is causing stress in your life. If there are any situations or activities that cause anxiety, see if you can reduce or avoid them. Lifestyle changes can sometimes be the best means to lower your overall stress levels.

Eczema Flare-Ups: The Bottom Line

The precise cause of eczema is unclear, but many different factors can trigger flare-ups. Everyone’s body is different, so there is no single factor that universally causes eczema for all patients. Being vigilant about your lifestyle, diet, and stress levels can help you identify your personal triggers.
