FULL STORY ======================================================================

Theres a huge array of tech that promises to help you sleep more deeply, and wake full of zest and energy in the morning. Sleep trackers , white noise machines , noise cancelling sleep earplugs , calming wake-up lights you
could easily pack your bedroom with machines and strap on a whole armful of watches in the interests of improving your nightly rest. But does any of it actually work?

To find out whether tech can genuinely help you sleep better and feel more rested, TechRadar spoke to James Wilson, aka The Sleep Geek . Wilson is a sleep behaviour and environment expert who specializes in helping people understand their sleeping habits, and make changes to their behaviour, environment, and mindset to sleep better.

Here, he shares his advice on the sleep tech that really makes a difference, the devices you should be wary of, and everything else you should know before making an investment. Aresleeptrackers helpful, or do they cause unnecessary anxiety aboutsleep?

Currently there are a number of issues with trackers. They're not massively accurate and we have to be careful to not take the data at face value. Secondly, we dont have the context to interpret the data, so although the tracker might be telling us we have had 30% REMsleep, we dont know it thats good or bad. Thirdly, trackers tell us as a poor sleeper something we already know: that we havesleptpoorly.

We cant force ourselves tosleepbetter, in the way we can exercise more or eat more healthily. Often trackers lead to greater anxiety and even worsesleep. I use them from time to time, particularly in sports where I have an athlete
not engaged with theirsleepenough, and a tracker can help that engagement. Beyond that, in my experience they make poorsleepworse.

However, as we move away from wearable to nearable and airable trackers, I
see a future where we can be tracked, but only notified when there is a
change that will be detrimental to us. A wake-up light slowly pulls you out
of the deeper stages of sleep rather than shocking you awake like an audible alarm (Image credit: Fitfort) Are there benefits to using a wake-up light rather than a regular alarm clock?

Massive benefits, and if you are going to bring a bit of technology into your bedroom then a wake-up light should be it.

An audible alarm shocks us into wakefulness, leaving us pressing snooze time and time again, and makes the whole wake up experience pretty horrid. A wake-up light slowly pulls you out of the deeper stages ofsleep, starts the body creating wake up hormones like cortisol and diminishes hormones
connected tosleeplike melatonin, so even if you still have an audible alarm, it's not such a shock to the system. Can a white noise machine help
yousleepat night?

Yes, for some people, and I would add pink noise into the equation too. Basically, our hearing is the last of our senses to switch off and the first of our senses to switch on as we move in and out ofsleep. It is our security system designed to protect us from predators. Sudden noise drags us into consciousness, and a noise machine or app has a constant soothing sound which relaxes and masks any sudden noises.

However, they're not for everyone, and some people find the constant noise incredibly irritating. Is wearing earplugs at night a good idea?

Yes, in a similar way to white or pink noise, earplugs help create a consistentsleepenvironment and help us rest more peacefully. Often
traditional foam or putty ones are hard to get used to, but brands like Flare and QuietOn have developed some innovative, reusable products. Some sleep
apps are overly prescriptive, or demand massive lifestyle changes (Image credit: Savalov Nikita / Shutterstock) Are there any smartphone apps that
youd recommend to people who struggle tosleep?

For me, it's focusing on content that can relax us and help prepare us forsleep. Tracking apps are pretty useless in terms of accuracy and drivesleepanxiety, and many of thesleepimprovement apps are overly prescriptive. They also demand massive lifestyle changes because they are based on approaches designed for chronic insomniacs.

Your meditation app of choice, whether it is Headspace , Calm or Insight
Timer . Spoken word book apps like Audible are great and podcast apps like Spotify or Apple Music give us access to content such as podcasts designed to besleep-inducing.
