Are neon signs bad for you?

Neon signs have become symbols of modern urban life. It creates sparkle and charm in urban space. But do these signs carry health risks that we need to be concerned about? Many people are worried about bright light, ultraviolet rays, and neon gas that can harm the human body. In this article, we will explore whether neon signs are bad for you?

Learn about neon signs 

Neon signs, with their colorful lights and unique style, have become a symbol of urban culture. They create highlights for bars, restaurants, stores and shopping centers. When night falls, neon signs sparkle brightly, bringing a lively space and attracting everyone's eyes.

Neon signs are made using long, thin glass tubes filled with neon gas or other noble gases. When an electric current passes through these gases, they emit bright, colorful light. The unique glow of neon signs has made them a popular form of advertising and decoration, adding appeal to a variety of settings.

Some harmful effects you should know

Ultraviolet radiation

One of the main concerns related to neon signs is ultraviolet radiation. Prolonged exposure to UV rays can be harmful to the skin and eyes, potentially leading to sunburn, premature aging and even skin cancer. However, it is important to note that the UV radiation emitted from neon signs is minimal and usually at safe levels. The glass tubes of neon signs act as a shield, reducing the amount of UV rays that can escape.


Neon signs, especially those using neon gas, may generate small amounts of ozone during operation. Ozone is a gas that can cause respiratory irritation and difficulty breathing when present in high concentrations. However, the levels of ozone produced by neon signs are generally very low and unlikely to pose a significant health hazard. Especially when used in well-ventilated areas.

Electrical hazard

Neon signs require high voltage current to operate. Improper installation or maintenance can lead to electrical hazards, such as electric shock or fire. It is important to hire a professional electrician to install and maintain neon signs to ensure proper wiring and safety measures are in place.

Measures for using safety lights

To enjoy the benefits of neon signs while minimizing any potential risks, you should:

Place neon signs in areas that do not come into direct contact with people. This reduces the risk of accidental exposure and minimizes the likelihood of exposure to ultraviolet radiation.

Ensure proper ventilation in indoor areas where neon signs are installed. Proper airflow helps dissipate the ozone produced, keeping air quality at a safe level. 

Regularly check and maintain neon signs to ensure they are not damaged and operate normally. Any signs of wear or problems should be promptly addressed by a professional.


Although there are some concerns associated with neon signs, when used and maintained properly, they will harm you. Neon signs themselves are not inherently harmful to human health. Neon gas is used in neon signs, giving them their characteristic bright glow, which is usually not harmful to humans in the small quantities contained in signs. 

However, it is important to note that neon signs, like any electrical equipment, must be manufactured, installed and operated in compliance with safety regulations to ensure they do not cause any damage. What risks? Improper handling of neon signs, such as breaking or tampering with the glass tube, can result in exposure to broken glass or electrical hazards, potentially causing injury.
