Detailed answer

Contact dermatitis can be caused by prolonged use of electronic devices due to several factors. Firstly, electronic devices such as smartphones and tablets often contain nickel, which is a common trigger for contact dermatitis. When in contact with the skin, nickel can cause redness, itching, and inflammation. Secondly, the constant friction between the device and the skin can damage the outer layer of the skin, leading to irritation and contact dermatitis. Additionally, using electronic devices for long durations can cause excessive sweating, and the combination of sweat and friction can further worsen irritation. It's important to take breaks, keep the devices clean, and use a protective case or barrier to minimize the risk of contact dermatitis.
