Safety is always a concern when it comes to electric blankets. Fortunately, modern heated blankets with zippers are designed with several safety features to mitigate risks. Many come with automatic shut-off timers that turn the blanket off after a certain period, preventing overheating. Additionally, they often feature overheat protection, ensuring that the blanket does not become too hot even if left on for extended periods. This is especially important for those who may fall asleep while wrapped in their cozy cocoon.
