Friend and Enemy: The Dual Nature of the Sun
As summer arrives and temperatures soar, the sun becomes an ever-present element in our daily lives. Some eagerly bask in its warmth, while others seek refuge in shade and layers of protective cream. Dermatologist Manuela Carrera from the Israelitic Hospital in Rome sheds light on the nuanced effects of sun exposure on our skin.
The Benefits of Sun Exposure for Certain Skin Conditions
Contrary to popular belief, the sun can be a valuable ally for specific skin diseases. Carrera highlights that the sun has an immunosuppressive effect on our skin, making it an adjuvant therapy for conditions such as psoriasis and atopic dermatitis. The UVA and UVB rays emitted by the sun have a beneficial impact on these conditions. However, moderation is key, and it is crucial to follow the advice of a dermatologist for appropriate therapies and exposure methods.
When the Sun Can Harm Your Skin
While the sun offers relief for psoriasis and atopic dermatitis, it can aggravate other skin pathologies. Carrera explains that individuals with lupus erythematosus should avoid sun exposure, as UV rays can trigger flare-ups of the disease. Similarly, those with vitiligo, a condition that lacks melanin defense, risk getting sunburned. It is essential for patients suffering from these conditions to exercise caution and protect their skin from harmful rays.
Interactions Between Sunlight and Medications
Certain medications, such as cortisone, can interact negatively with sun exposure. These photosensitizing drugs increase the skin’s sensitivity to UV damage, leading to adverse reactions like blistering, rashes, burns, and spots. Antibiotics, anticoagulants, contraceptives, antidepressants, antifungals, cortisone, antihypertensives, retinoids, and statins are among the drugs that require extra attention when it comes to sun exposure. It is crucial to consult a doctor for guidelines and precautions.
The Importance of Sunscreen All-Year-Round
Many individuals mistakenly believe that sunscreen is only necessary during beach visits. However, Carrera advises using sunscreen daily, even in the city. The sun’s rays can affect individuals during walks or outdoor sports activities. Those with light skin, a history of pre-cancerous diseases, or skin tumors should apply a high SPF sunscreen, regardless of location. Carrera emphasizes the following measures: apply sunscreen 20 minutes before sun exposure, reapply every 2 hours, choose water-resistant protections if swimming, select protection based on phototype, and opt for antiaging filters that protect against UVA, blue light, visible light, and infrared.
Remember to Consult a Doctor
It is important to note that the information provided here aims to complement rather than replace the relationship between a patient and their doctor. Dermatologists can provide personalized advice and guidance based on an individual’s specific needs, history, and condition.
In conclusion, the sun can be both a friend and foe to our skin. Understanding its effects and harnessing its benefits through responsible sun exposure can lead to improved skin health. By following the advice of dermatologists like Manuela Carrera, individuals can strike a balance and protect their skin while enjoying the summer sun.
