Two-thirds of Britons think their workload is having a negative effect on their health, a study has found.
Researchers who polled 2,000 adults found that those who worked at desks often thought they were too busy to take a break.
Seven in ten Britons suffered aches and pains as a result of staring at their computer screens for prolonged periods.
The study, commissioned by Philips LED lighting, found three in 10 said their worsening health is a result of being too busy to eat well.
Dr Hilary Jones, said: “Many people spend at least six hours a day looking at screens either on their mobiles, looking at the television or working on computers.
"The normal blink rate is 10 to 15 times per minute, but this is 60 per cent reduced when looking at computer screens and the most common of all eye disorders is dry eye syndrome which is very much on the increase.”
The research, conducted via OnePoll, found UK professionals typically spend an hour and 28 minutes at their screen before taking a break.
When workers take time away from their desks, their breaks only lasted 10 minutes on average.
Dr Hilary Jones added: “There are things you can do to help make you comfortable while desk-working for long periods of time and prevent aches and pains.
"If you’re working from home a lot, installing quality LEDs can provide a nice warm light and have advantages including improved eye comfort.”
Elina Enqvist-Twomey, Philips LED Product Manager, said: "Screens with their artificial light are dominating our lives.
"Our priority is to ensure we produce quality energy-efficient LED lamps and luminaires that not only reduce environmental impact but make people more safe, productive and comfortable in their own home.”
