Pharmacist explains how fans can dry out skin and eyes

While winter is often associated with dry skin due to cold temperatures and heating, everyday habits can also contribute to moisture loss. Pharmacist Karla Pires explains that using fans, a common practice in climate-controlled environments, can inadvertently worsen skin dehydration.

Pires, speaking to HOLA magazine, noted that the constant air circulation from a fan accelerates the evaporation of water from the skin's surface. This process, known as transepidermal water loss (TEWL), can leave the skin feeling dry and dehydrated. Although the entire body can be affected, the lips and eyes are particularly vulnerable due to their sensitive nature.

Lips, with their thinner natural barrier and fewer sebaceous glands, are prone to cracking. In the eyes, continuous airflow can disrupt the tear film, causing dryness, itching, burning, or a gritty sensation, especially after prolonged exposure. Pires also highlighted that individuals with sensitive skin are more susceptible to these effects because their skin barrier is less tolerant of water loss.

To counteract these issues, specialists advise against intense direct airflow. They recommend maintaining ambient temperatures between 24 and 26 degrees Celsius and using fans on low or medium settings. It is crucial not to direct the fan's airflow straight at the face, particularly during sleep or for extended periods. Instead, orienting the fan towards other body parts or ensuring sufficient distance can help cool the environment without causing irritation.

Reinforcing daily skin hydration with products that strengthen the skin's protective barrier is also recommended. By following these simple precautions, individuals can continue to use fans for comfort without compromising the health of their skin and eyes.
