What is a benefit of wearing short sleeves while working on computers?

Wearing short sleeves while working on computers can significantly reduce static electricity risks. This is particularly relevant in the context of handling sensitive electronic components. When wearing long sleeves, there is a greater chance of generating static electricity through friction, especially when the fabric rubs against the arm or other materials. These static discharges can easily damage sensitive electronics, such as circuit boards or connectors. By opting for short sleeves, the surface area for potential static generation is reduced, and this simple adjustment can help mitigate the risk of electrostatic discharge, which can be detrimental to the components being handled.

The other choices, while they may have some validity, do not address the primary concern of static electricity as directly or effectively as the correct option does. Enhancing comfort and improving mobility are benefits of wearing short sleeves, but they are secondary to the critical factor of static discharge protection. Preventing snagging on components is also a consideration, but it does not specifically address the broader implications for electronic safety that static electricity poses.
