This is particularly evident in the form of spider veins—small, visible red or purple blood vessels—on the face and legs. Heat causes superficial veins to expand in order to help the body release excess warmth, but frequent or prolonged dilation can weaken vessel walls and make these veins more prominent over time (source). People with fair or sensitive skin are especially prone to visible redness and spider veins, as their skin offers less natural protection against environmental stressors.

Studies have shown a higher incidence of telangiectasia (spider veins) and persistent facial redness in populations exposed to hot climates or heatwaves, particularly among women and individuals with predisposing genetic factors (source). Preventive measures include avoiding excessive heat exposure, using cool compresses, and applying broad-spectrum sunscreen daily to minimize UV-triggered vascular changes. For those already affected, dermatological treatments like laser therapy can reduce the appearance of spider veins. As global temperatures rise, awareness and proactive skin care are key to managing heat-induced vascular changes and visible redness.

Shingles, or herpes zoster, is a painful skin eruption caused by the reactivation of the varicella-zoster virus—the same virus responsible for chickenpox. Climate-related events such as heatwaves, wildfires, and extreme storms are linked to heightened psychological stress and weakened immune responses, both of which can increase the frequency and severity of shingles outbreaks (source). Stress prompts the release of hormones that suppress the immune system, reducing the body’s ability to keep dormant viruses in check.

Recent hospital reports have shown spikes in shingles cases following major natural disasters and periods of extreme weather, particularly among older adults and individuals with preexisting health conditions (source). Symptoms include a painful, blistering rash—often on one side of the body—accompanied by burning, tingling, or numbness. To reduce risk, experts recommend stress management techniques, maintaining a healthy lifestyle, and vaccination for those over 50 or with weakened immune systems. As climate change increases both physiological and psychological stressors, staying vigilant and seeking prompt medical care is crucial for those at risk of aggravated shingles outbreaks.

Sunspots, also known as solar lentigines or age spots, are persistent brown patches that develop on sun-exposed areas of the skin after years of cumulative ultraviolet (UV) exposure. Climate change is resulting in more days of intense sunlight and higher UV indices, which in turn accelerates the formation and darkening of these spots (source). Older adults are especially prone to sunspots, as their skin has endured decades of sun exposure, and aging further reduces the skin’s ability to repair UV-induced pigment changes.

Studies have found a higher prevalence of lentigines among populations living in regions with consistently high UV radiation, such as Australia and the Mediterranean (source). These spots, while benign, are often cosmetically concerning and can sometimes be mistaken for more serious skin lesions. Preventive strategies include diligent use of broad-spectrum sunscreen, wearing hats and protective clothing, and avoiding sun exposure during peak hours. For existing sunspots, dermatologists may recommend topical treatments, chemical peels, or laser therapy. As climate change continues to intensify sun exposure, protecting the skin from UV damage is crucial to minimizing the appearance and severity of lentigines.

Skin tags, or acrochordons, are benign skin growths that often appear in areas of friction such as the neck, underarms, and groin. Climate change is indirectly contributing to a rise in skin tag incidence by increasing factors that promote their formation—namely, excessive sweating and weight gain during prolonged heatwaves. High temperatures drive more perspiration, which, combined with skin-to-skin contact or tight clothing, creates ongoing friction that stimulates the growth of these harmless lesions (source).

In addition, heatwaves are associated with decreased physical activity and dietary changes, leading to increased rates of obesity, a known risk factor for skin tag development. Studies have shown that overweight individuals are more likely to develop skin tags, especially in hot and humid environments (source). To reduce risk, experts recommend maintaining a healthy weight, wearing loose, breathable clothing, and practicing good hygiene to minimize friction and moisture in skin folds. While skin tags are not dangerous, they can be bothersome or cosmetically concerning. Dermatological removal is simple, and preventive measures can help limit their formation as climate conditions evolve.

Windburn occurs when strong, dry winds strip away the skin’s natural oils and moisture, leading to redness, stinging, flaking, and heightened sensitivity. As climate change intensifies weather patterns, many regions—especially coastal zones—are experiencing stronger, more persistent winds and lower humidity, which amplify the damage caused by windburn (source). Coastal communities in places like California and Australia have reported increased cases of windburn, especially during storm seasons and periods of shifting oceanic currents.

Windburn is often mistaken for sunburn, but it uniquely results from the mechanical and drying effects of wind rather than UV exposure. Exposed areas such as the face, lips, and hands are most vulnerable. To prevent windburn, dermatologists recommend applying thick, protective moisturizers, using barrier creams, and wearing physical protection like scarves, hats, and gloves during windy conditions. Hydration is also key to maintaining skin resilience. As climate change leads to more intense and frequent wind events, awareness and proactive protection are necessary—particularly for those living in coastal or high-wind regions—to minimize skin irritation and long-term damage.

As climate change brings new insect species into previously temperate regions and raises overall temperatures, the risk of secondary skin infections from bug bites is on the rise. Warmer climates support longer breeding seasons and larger populations of mosquitoes, biting flies, and other arthropods (source). When people scratch itchy bites, they break the skin’s protective barrier, creating an entry point for bacteria such as Staphylococcus aureus and Streptococcus, which can cause cellulitis, impetigo, or even more serious infections.

Recent studies have documented a growing number of skin infections in areas experiencing surges of new or unusually high insect populations, such as the American Midwest and southern Europe (source). Children and individuals with compromised immune systems are especially vulnerable. To lower the risk of infection, experts recommend using insect repellents, wearing protective clothing, and cleaning bites promptly with soap and water. Avoiding scratching and covering bites with bandages can also prevent bacteria from entering. As insects expand into new territories and bite rates increase with rising temperatures, vigilance and proper care are essential for reducing bug bite-related infections.
