Young Brunette Girl With A Laptop Strips On The Couch In The Living Room

Ergonomics and health
Because of their small and flat keyboard and trackpad pointing devices, prolonged use of laptops can cause repetitive strain injury. Usage of separate, external ergonomic keyboards and pointing devices is recommended to prevent injury when working for long periods of time; they can be connected to a laptop easily by USB or via a docking station. Some health standards require ergonomic keyboards at workplaces.
The integrated screen often causes users to hunch over for a better view, which can cause neck or spinal injuries. A larger and higher-quality external screen can be connected to almost any laptop to alleviate that and to provide additional "screen estate" for more productive work.
A study by State University of New York researchers found that heat generated from laptops can raise the temperature of the scrotum when balancing the computer on one's lap, potentially putting sperm count at risk. The study, which included roughly two dozen men aged 21 to 35, found that the sitting position required to balance a laptop can raise scrotum temperature by as much as 2.1 °C (3.78 °F). However, further research is needed to determine whether this directly affects sterility in men.
