Final answer:
Cell phone use can be restricted for IDL holders due to radiation exposure risks, interference with important equipment, and negative impacts on personal and social aspects.
Step-by-step explanation:
IDL holders may not use a cell phone for various reasons. One reason is that cell phones emit radiation, and using them close to the head can increase exposure to this radiation. To minimize this risk, it is recommended to use hands-free devices and keep the mobile phone away from the body.
Additionally, there are situations where cell phones may interfere with important communications or medical equipment that use similar radio frequencies. For example, in airplanes and hospitals, it is often requested to switch off or put cell phones into airplane mode to prevent such interference.
Lastly, cell phones can also have negative impacts on personal and social aspects. Research has shown that cell phone use can make it harder to focus on tasks, give undivided attention, and separate work from personal life.
