Napping on the job is generally frowned upon, but a growing number of companies are offering new services and products to allow their employees to take a quick snooze at work to help manage their health and improve productivity.
Companies are creating special areas for short daytime naps, and some have launched in-house seminars to explain the importance of sleep to employees.
The move comes amid the spread of smartphones and other digital devices, which have been blamed for making people sleep fewer hours than before.
