Lead poisoning typically occurs when lead enters the bloodstream, either through ingestion or absorption. Christmas lights, may contain a lead coating in the wiring. Over time, the lights can develop lead dust as they deteriorate, especially if they are not properly stored.
When parents set up the holiday decorations and do not wash their hands afterward, they risk transferring the lead onto their children, particularly babies or toddlers, who are often in close contact with their caregivers. Even a small amount of lead exposure can be harmful, and children are particularly vulnerable because their brains are still developing. Lead poisoning can lead to developmental delays, learning disabilities, and other serious health problems.
