Not all glass blocks out UV rays. Standard windows may block UVB rays, the type responsible for sunburn, but many fail to filter UVA rays effectively. These longer-wavelength rays can penetrate deeper into the skin, contributing to premature aging and increasing the risk of skin cancer over time. For office workers sitting near large windows or brightly lit spaces, daily exposure to UVA rays could accumulate, even if it’s not immediately noticeable.  

Another often overlooked aspect is the type of glass used in office buildings. While tinted or treated windows can reduce glare and heat, they don’t always offer adequate UV protection.  

The good news is that employers and employees can take practical steps to mitigate these risks. One of the simplest yet most effective solutions is the application of UV-blocking window films. These films can block up to 99% of harmful UVA and UVB rays without compromising natural light. Installing blinds or curtains to reduce direct sunlight exposure is another easy fix, though it may require balancing aesthetics and comfort.  

Wearing clothing that covers exposed skin, such as long sleeves, is also an effective strategy for personal protection. Employees can also consider applying broad-spectrum sunscreen daily - even indoors - particularly if seated near windows. Sunscreen isn’t just for outdoor activities; it can serve as a valuable layer of protection against incidental exposure during work hours.  

While preventative measures are crucial, they should be complemented by regular skin checks for all employees, not just those working outdoors. Many skin cancers are treatable when detected early, making workplace skin checks an essential part of any well-being program. Regular skin assessments help identify potential issues early and raise awareness among employees about the importance of monitoring their skin health.  

By integrating skin checks into workplace well-being initiatives, you can demonstrate a commitment to employee health while fostering a proactive culture around skin cancer prevention. Offering on-site or subsidised skin check services can make it easier for employees to prioritise their health without disrupting their work schedules.  

UV exposure indoors is a silent but significant risk that deserves more attention. From understanding the limitations of window panes to adopting protective practices, there are actionable ways to safeguard employees from the harmful effects of UV rays. And while prevention is key, regular skin checks remain crucial to comprehensive workplace well-being programs.
