Night surfing sounds like something dumb people here in Florida do just before they get eaten by Jaws. In a different context, it refers to people using their computers in bed, and a recent study showed that more people are paying less attention to their partners than to their laptops, which is bad for relationships.

If you’re reading SexIs, chances are you’re more interested in turning your partner on than turning your tech devices on, so this probably doesn’t refer to you. But a study of two million people in Great Britain by Ikea showed that 22 percent of Londoners use their computer in bed, the most in England, according to the Daily Mail.

And if it’s happening with the Brits our guess is it’s probably happening in tech-happy America, too.

“Facebook is cited in one in five divorces, according to lawyers, while a survey by website Divorce Online found that the phrase ‘mobile phone’ occurred in one in eight divorces citing unreasonable behavior,” the Mail reports. Not only is night surfing bad for your love life because it makes people feel like you’re ignoring them (which you are) but Phyllis Zee, neuroscience professor at Northwestern University in Chicago, suggests it’s not great for your sleep either: The light from the computer messes with your circadian rhythms.

So unless you’re looking for some mood-inspiring erotica together, turn off your computer. It’s better than turning off your partner.
