How does heat and sun affect Hidradenitis Suppurativa in the summer?

Heat and sun exposure can potentially affect Hidradenitis suppurativa (HS) in different ways. While the impact may vary from person to person, here are some general considerations:

Heat: Excessive heat can lead to increased sweating, which may exacerbate HS symptoms. Increased sweating can worsen inflammation and contribute to the development of new lesions or the enlargement of existing ones. Additionally, heat and humidity can create an environment conducive to bacterial growth, increasing the risk of infection. It is advisable for individuals with HS to try to keep cool, avoid overheating, and take measures to manage excessive sweating, such as wearing loose-fitting, breathable clothing and using absorbent materials. Blow drying moist areas such as the armpits, groin, and under the breasts can help to keep these sites dry. Gentle fragrance-free antiperspirants can be applied at night to moist areas, to prevent sweating during the day. Anti-chafing sticks or powders can also minimize skin friction. Hidrawear is a brand that provides clothing specifically for individuals with HS, with breathable material and built-in dressing systems.

Sunlight: Sun exposure does not directly impact the underlying causes of HS. However, some individuals with HS may find that sunlight or ultraviolet (UV) radiation has varying effects on their symptoms. Sun exposure can lead to skin damage, including sunburn, which can cause additional inflammation and discomfort in HS-affected areas. Conversely, some people with HS report that exposure to sunlight or UV light may temporarily alleviate symptoms or provide a calming effect. However, the benefits of sun exposure should be weighed against the potential risks, and it’s important to protect the skin from excessive sun exposure to minimize the risk of sunburn and other skin damage.

It’s worth noting that individual responses to heat and sun exposure can differ, and what works for one person may not work for another. It’s important to pay attention to how your body responds and take necessary precautions to manage your HS symptoms. Consulting with a dermatologist or healthcare professional can provide personalized advice and guidance on managing HS in relation to heat and sun exposure. Organizations such as the HS Foundation, Hope for HS, and HS Connect are a great resource for support groups and guides on living with HS.
