Fitbit’s research director Dr Conor Heneghan defended tracking devices, saying that they can emphasise the importance of a consistent bedtime and wake time. He added: “What we’re trying to do is give people a tool to understand their own sleep health.”

What’s not in doubt is that there is plenty of advice out there about how to get a good night’s sleep, from cutting down on screen time just before going to bed to avoiding caffeine and listening to soothing podcasts to send you into the land of dreams.

Sleep trackers can be part of the mix, as long as we understand how to use it, and don’t get obsessed with it.

“We want to partner with out patients to improve their sleep,” Khosla said. “This means that we need to understand sleep technology – including its limitations – without dismissing this potentially valuable resource.”

Khosla said that one thing we should do is let go of the idea that there is such a thing as a “perfect” night’s sleep.

That’s something we can get behind; as women we can feel so much pressure to be perfect in all parts of our lives, we don’t need to strive for perfection when we’re sleeping as well.
