Do You Really Need to Wear Sunscreen Indoors? Separating Fact from Fiction

As we spend more time indoors, surrounded by artificial lighting and screens, we may wonder if sunscreen is still necessary. After all, we’re not basking in the sun’s rays, so what’s the harm? The answer lies in understanding the role of sunscreen and the types of radiation we’re exposed to indoors.

Fiction: Sunscreen is only for outdoor use

While it’s true that sunscreen is designed to protect against ultraviolet B (UVB) radiation, which is primarily responsible for sunburn and skin cancer, it’s not just about being outside. There are other types of radiation that can also cause harm, and sunscreen can provide protection against these as well.

Facts: UV radiation indoors is real

Even when we’re indoors, we’re still exposed to UV radiation from various sources:

• Window glass: While glass can filter out some UV radiation, it doesn’t block all of it. In fact, many types of glass, like untreated windows, allow up to 20% of UVB radiation to pass through.
• Electronic devices: Computers, smartphones, and televisions emit low levels of UV radiation, particularly in the blue-violet range.
• Fluorescent lighting: These lights, which are commonly used in offices and homes, emit UV radiation as well.

Facts: Other forms of radiation are also present

In addition to UV radiation, there are other forms of radiation that can also cause harm:

• Blue light: This type of high-energy visible (HEV) radiation is emitted by electronic devices and can cause eye strain, disrupted sleep, and even contribute to the development of age-related macular degeneration.
• Infrared radiation: This type of radiation, often referred to as heat, is emitted by electronic devices, appliances, and even the human body. Prolonged exposure to infrared radiation can lead to heat stress, skin irritation, and other health issues.

So, do you really need to wear sunscreen indoors?

While sunscreen may not be necessary for every indoor situation, there are certain circumstances where it can provide additional protection:

• If you spend extended periods in front of screens: Wearing sunscreen with broad-spectrum protection (UVA and UVB) can help shield your skin from blue light and UV radiation emitted by electronic devices.
• If you’re exposed to fluorescent lighting: Certain types of sunscreen can provide protection against UV radiation emitted by fluorescent lighting.
• If you’re indoors with windows that don’t block UV radiation: If you’re in a building with windows that allow UV radiation to pass through, wearing sunscreen can provide an added layer of protection.

Tips for indoor sunscreen use

If you decide to wear sunscreen indoors, follow these tips:

• Choose a broad-spectrum sunscreen: Select a sunscreen that protects against both UVA and UVB radiation.
• Use a lightweight, non-greasy formula: Opt for a sunscreen that won’t leave a residue on your skin or clothing.
• Apply it correctly: Apply sunscreen according to the product’s instructions and reapply as needed.
• Don’t overdo it: You don’t need to apply sunscreen liberally; a thin layer is sufficient for indoor use.

In conclusion, while sunscreen is primarily designed for outdoor use, it’s not the only type of radiation we’re exposed to indoors. By understanding the different forms of radiation and taking steps to protect ourselves, we can enjoy the benefits of modern living while minimizing the risks associated with indoor radiation.
