Is climate change affecting eczema?
According to recent research, it is—but it depends on where you live.
In this post, we take a look at the impact climate change can have on your symptoms and what you can do to make your skin look and feel more comfortable.
Climate change affects eczema: What the research shows
Scientists published a new review in June 2024. They looked at 18 studies that looked at the effects of climate risks and atopic dermatitis (AD), another name for eczema.
They found that most climate hazards had evidence of worsening AD symptoms, with effects varying from direct to indirect effects.
For example, an increase in wildfires in some areas could worsen symptoms in those caused by the presence of particulate matter in the air. This was an immediate result. Then there were indirect effects, such as food insecurity and drought-induced migration.
Jessica Johnson, MPHdirector of community research and engagement at the National Eczema Association, noted that the majority of climate risks linked to greenhouse emissions “have a negative impact on the prevalence, severity, and health care utilization of NA.
He added that the impact of climate change on AD is “influenced by geographic region and climate,” with rainfall appearing to increase the risk of AD in children in the U.S. Studies in other geographic areas, however, have shown that rainfall is associated with increased AD symptoms only when daily rainfall was below a certain threshold.
The scientists also created maps that show how climate hazards affected eczema in some geographic areas, plotting cumulative exposure in 2005 and 2017, as well as projections to 2053. Maps from 2005 and 2017 showed overlap between areas with greater exposure to climate hazards and increased prevalence of atopic dermatitis. The 2053 maps were used to indicate those areas likely to be most affected in the future.
Ultimately, the scientists noted that more data was needed, particularly from those regions most likely to face more climate risks.
Other studies support the idea that climate change is affecting eczema
This is not the only study looking at this issue. Scientists reported in 2021 that Eczema is an ‘environmental disease’ noting that climate change “alters pollen allergenicity, which increases atopic eczema symptoms in some patients during the pollen season.”
Some eczema sufferers know that pollen triggers them and plants tend to produce more pollen in warmer temperatures. Temperature increases associated with climate change can increase pollen levels, which can worsen symptoms.
Researchers also reported in 2023 that both cold and hot temperatures can affect itchingskin eruptions, skin barrier dysfunction and development of AD.
Harvard Health reported in the summer of 2024 that wildfires in Quebec and the resulting dense fog over Boston, Massachusetts, increased eczema and dermatitis outbreaks in patients. When scientists examined itfound a marked rise and atypical summer peak in carbon monoxide levels in the Boston area while the fires were ongoing, and this was associated with a sharp increase in eczema-related disease, dermatitis, and dermatology clinic visits.
Air pollution, exacerbated by wildfires, can damage the skin through smoke and firefighting chemicals. These can cause inflammation in the skin, which leads to itching, rash, dryness and breakouts.
The link between climate change and eczema
In general, climate change can affect eczema in three main ways:
Increased Allergens
As the planet warms, the pollen season is getting longer and more intense. This means more allergens are floating around, which can trigger an eczema flare-up. Climate change also affects mold and dust mites, which can also cause symptoms.
Extreme weather phenomena
Heatwaves, heavy rains and humidity are becoming more frequent due to climate change. Excessive heat can dry out your skin and worsen itching, while high humidity can lead to excessive sweating, which is another eczema trigger.
Air pollution
Air quality decreases as pollutants increase. Ozone and particulate matter irritate the skin and can worsen eczema symptoms.
Climate change affecting eczema: Managing your symptoms
Being aware of what the weather is doing in your area can help you take precautions to increase your skin’s resistance and reduce your symptoms. Here are some practical tips to help keep your eczema under control.
Stay hydrated
One of the best ways to fight eczema is to keep your skin well moisturized. In dry, hot weather, our skin can quickly lose its moisture. Use a thick, emollient moisturizer daily and always apply immediately after bathing to lock in moisture.
Look for fragrance-free products designed for sensitive skin, such as Calming Moisture and Body Repair Lotion. Both are designed to help protect the outer barrier while providing deep nourishing moisture.
Choose your skin care products wisely
Choose gentle, hypoallergenic products. Avoid soaps and cleansers with harsh chemicals, as they can strip your skin of its natural oils, further drying it out. Also avoid alcohol-based toners, as they are drying and can make your symptoms worse.
We recommend using Rescue + Relief Spray as a tonic and refresher at all times. It is cooling, soothing and hydrating and helps to keep the skin moist throughout the day. It also helps prepare the skin for moisturiser, balancing pH levels and taming inflammation.
Allergen control
To deal with increased allergens, keep your environment as allergen-free as possible. Clean your home regularly to reduce dust and mold. Use HEPA filters in your air purifiers and consider keeping windows closed during high pollen seasons. Wash bedding and pillowcases frequently in hot water to reduce dust mites. Use a humidifier in your bedroom if you live in a dry climate.
Stay cool and hydrated
Since heat and humidity can trigger eczema symptoms, stay cool and dry. Wear light, breathable fabrics such as cotton and avoid overheating. Stay hydrated by drinking plenty of water, which helps maintain your skin’s moisture balance.
Manage stress
Climate change can be a source of stress, and stress is a known trigger for eczema flare-ups. Find ways to manage stress through relaxation techniques such as deep breathing, meditation, yoga, journaling and meditation. Find activities that you enjoy and that help you de-stress every day.
Monitor your surroundings
If air pollution is a concern in your area, limit your time outside during periods of high pollution. Check local air quality reports and stay indoors on days when pollution levels are high. Using a high-quality indoor air purifier can also help reduce exposure to pollutants. Houseplants also help clean indoor air, as long as you keep them well cared for and prevent mold.
