Eczema is a common inflammatory skin condition that is associated with itchiness and difficulty sleeping, which commonly affect quality of life. It occurs mostly during childhood but can often affect adults. Typically childhood eczema improves with age in 80% of the cases. Eczema is often associated with other conditions like asthma. Multiple things have been found to cause eczema flares, and environmental, dietary, psychological, and lifestyle factors are all considered as some of the potentially modifiable triggers of these flares. Genetics, environment, and weather are some examples of non-modifiable triggers.
Diet can have a profound correlation with eczema, and it is estimated that it is associated with food allergy or food sensitivities in approximately one third of children. Cow’s milk, eggs, peanuts, soy, wheat, nuts and fish are some of the common food allergies in children with eczema. Further research is needed on elimination diets for those with eczema.
Lifestyle can play a role in eczema flare-ups. Smoking is one of the modifiable lifestyle choices that can be made. Significantly more smokers suffer from chronic hand eczema than non-smokers, and the association between eczema and depression is higher in smokers than it is in non-smokers. Even pre and postnatal exposure to second hand smoke can increase the risk of eczema development later in life.
Eczema and stress have a fairly understandable connection. The skin is visible to those around us, and any blemish can seem much more prominent than it may actually be. In the case of eczema, not only the visible lesion but also the sensation can have psychological effects. The severe itch sensation can cause anxiety, and patients with eczema generally rate higher on tests that evaluate depression, anxiety, private body consciousness, quality of life, and interaction anxiousness.
There is a complex relationship between sleep and eczema. Patients with eczema have a higher chance of regular insomnia. Poor sleep can lead to a worsening of itch sensation and more scratching events at night, possibly due to problems with temperature regulation within the body. Even the parents of children with eczema suffer from sleep disruptions.
Environmental factors, such as dust mites, pollen, and plants like mugwort, birch and grasses are considered triggers in a number of patients with eczema. Other factors that have been found to trigger eczema flare-ups can include: wool, nylon clothing, pets, sweating and the use of shampoo, especially during cold weather.
There is a psychological correlation with eczema that has been defined, showing that depression, anxiety and stress are associated with the condition. These psychological facets can reduce quality of life and make healing more difficult.
What Are Ways to Avoid Eczema Flare-Ups?
It is important for people with eczema to first understand what is responsible for the flares they experience. When the source of the flare-ups is found, it can be easier to avoid them. Some of the lifestyle choices may be the simplest of all triggers to avoid, but others can be quite difficult. Clothing-induced flares can be prevented simply by not wearing or coming in contact with that type of clothing. Hygiene and personal care products can be avoided if they are the triggers. Shampoo use can be minimized or substituted with a gentler type in order to prevent future flares.
If the eczema flares are suspected to be caused by a food allergy or sensitivity, it is best that they are identified with an oral food challenge or though skin testing. Once they have been identified they can be eliminated from the diet, which can often result in dramatic improvement of symptoms.
A difficult trigger to remove from the lifestyle is smoking. Tobacco smoking can be one of the most difficult things to quit, but can often be one of the most beneficial for health. In addition to the benefits that quitting can have on the heart and lungs, smoking cessation can be important to the health of the skin.
Many different forms of management exist to control flares that are caused by psychological stress.
Sleep can be improved by many things. Pharmaceuticals, natural products, relaxation techniques, and stress relief methods are just some of the things that can be used to improve sleep. If the poor sleep is caused by itching, there are also multiple approaches that can be used to improve that symptom.
Although it may be a difficult choice, it may be necessary to consider removing a pet from the home if that pet is the source of the flare. The difficulties of trigger avoidance come with the uncontrollable environmental factors. Dust can be controlled through regular cleaning but continues to affect those people whose eczema is worsened by that dust. One study demonstrates that avoidance of indoor allergen exposure is only effective when allergenic foods are also avoided. Pollen, grasses, and other plants are more difficult to avoid, especially if parts of those plants are airborne.
Overall, flares of eczema can be caused by a number of controllable and non-controllable factors. Knowledge of triggers may be one of the most important aspects to manage eczema symptoms. When you understand the cause of a flare, you can then make the necessary changes to avoid or minimize contact with that trigger.
