The truth about sleep paralysis

  The truth about sleep paralysis Is sleep paralysis simply a bad dream or something more serious?But what causes sleep paralysis, is it dangerous and how do you treat it? We spoke to Amy Gallagher, senior sleep physiologist at Bupa’s Cromwell Hospital; and Dr Nerina Ramlakhan, a physiologist and sleep therapist; and sleep expert James Wilson AKA The Sleep Geek, to find out more about the causes, triggers and treatment options for sleep paralysis:

Despite all the buzzy recovery gear and gadgets on the market, there’s one thing companies can’t package up and put a price tag on: sleep. But a good night’s sleep is the very foundation of performance – and experts say it may actually be the single most important factor in exercise recovery, according to new research from the International Journal of Sports Medicine.

A good night’s sleep is so crucial to exercise recovery and performance that the sleep tracking wearable business is booming; sales are projected to grow 15.8 percent per year between 2020 and 2026, according to market reports. But are these devices even accurate? It depends on the device you’re using, a December 2020 study published in the journal Sleep found.

Dr. Thanuja Hamilton of Avocare Sleep Physicians of South Jersey explains why fitness trackers may not be recording your sleep accurately . Hamilton says that some trackers overestimate your sleep , while others underestimate it -- and that if you're worried about sleep quality, it's better to simply

The gold-standard sleep assessment technique, polysomnography (PSG), isn’t possible outside of a laboratory or clinic, so researchers compared the results of four wearable sleep-tracking devices (Fatigue Science Readiband, Fitbit Alta HR, Garmin Fenix 5S, Garmin Vivosmart 3) and three non-wearable (EarlySense Live, ResMed S+, SleepScore Max) sleep-tracking devices against the mobile sleep assessment standard, actigraphy. They found that all of the devices except the Garmin performed as well as or better than actigraphy on sleep/wake performance measures.

Additional research published in the Nature & Science of Sleep Journal in October 2020 found that the Fitbit Ionic and the Oura Smart Ring possessed the lowest degrees of error in sleep tracking compared to an electroencephalography (EEG)-based device as well as other wrist-based trackers, including the Beddit Sleep Monitor 3.0, Fatigue Science Readiband, Polar A370, and WHOOP Strap 2.0. The Apple Watch Series 3 and Garmin Vivosmart 4 fell at the other end of the spectrum.

  Under Armour TriBase Reign 2 vs Nike Metcon 6: which is the best workout shoe? Under Armour TriBase Reign 2 vs Nike Metcon 6: one of these workout shoes is worth your hard earned moneyBefore we go any further, it's best to point out what the difference is between the best workout shoes and the best running shoes. After all, you can run in workout shoes and work out in running shoes, right? Absolutely, but there is a difference in performance and comfort levels when using the right shoes for the right type of training.

Is your running watch accurately tracking sleep ? Research says maybe not . If shops and pubs re-open but we are all in hospital there is unlikely to be a run on holidays and lager.

What that really means is 'if you’re asleep, most these devices are going to correctly determine – with 90 to 95 percent accuracy – that you are indeed asleep,' says the Sleep study author Evan Chinoy, a sleep research scientist at the Naval Health Research Center in San Diego, CA. 'However, if you’re in bed trying to sleep but still awake, they’ll only perform at a medium level of accuracy.'

That’s likely because, if you’re not moving and your heart rate is low, the devices – which typically use an accelerometer to detect movement and a light-based sensor to detect heart rate – have a harder time determining whether you’re actually awake or asleep.

In general, the devices tended to overestimate sleep and underestimate wake. The study authors hypothesised that Garmins’ relatively higher threshold for wake and lower threshold for sleep is what resulted in their poor performance. They also tended to perform worse on nights with poorer or disrupted sleep, meaning your data in the morning may say you had a good night’s sleep, even if you were tossing and turning throughout, says Chinoy.

Fitbit tips and tricks: Get more from your Inspire, Charge, Versa and Sense trackers

  Fitbit tips and tricks: Get more from your Inspire, Charge, Versa and Sense trackers Fitbit tips and tricks: Get more from your Inspire, Charge, Versa and Sense trackersThe Fitbit app is comprehensive and while the basic features it offers might be obvious, some of Fitbit's best functions are a little harder to find. This feature highlights all the tips and tricks of the Fitbit app to help you get the most out of your fitness tracker, with device-specific tips at the bottom.

So here's the sleep tracking situation right now: It works accurately , but not in real-time. You don't need a bunch of PhDs to work on sleep research for years to come up with something Apple has neglected sleep tracking apps and APIs so far even though the Watch has the ideal hardware for it.

Again, the sleep tracking function in smartwatches measures movement and maybe heart rate. It doesn’t measure brain waves, which are The biggest disadvantage with smartwatch sleep tracking isn’t a matter of technology, but a matter of timing. The batteries that power many smartwatches last

Most new wearables also track the sleep stages you cycle through throughout the night. But 'in terms of tracking light, deep, and REM sleep, basically, all of the devices performed at only a medium level of accuracy,' says Chinoy. Translation: There’s only about a 50-percent chance your data is accurate. 'These devices really shouldn’t be looked at for sleep staging at this point,' Chinoy adds.

That’s not to say they won’t be capable of better discriminating between sleep stages or providing even more data as the algorithms used by the devices evolve. (For what it’s worth, most of the devices in both of these studies have since been replaced by new versions that likely have even more sophisticated sleep tracking sensors in them.)

Eventually, these devices might provide actionable advice that can help you change your behaviour to optimise your sleep, says Brandon Peters-Mathews, M.D., a sleep medicine doctor at Virginia Mason Medical Center in Seattle and the author of Sleep Through Insomnia. 'Insights may prompt reduced intake of caffeine or alcohol late in the day, daytime exercise or a cooler bedroom to enhance deep sleep, or prolonged wakefulness may be eliminated by reducing the time in bed,' he adds.

What is deep sleep and how can you get more of it?

  What is deep sleep and how can you get more of it? What are the different stages of sleep, and what happens if you don’t get enough deep sleep? Here, experts explains everything you need to know … What are the different stages of sleep? “There are various ways to describe the stages of sleep but essentially we have four which go from light to deep, physically restorative sleep, and then REM sleep,” says sleep psychologist Stephanie Romiszewski, on behalf of LloydsPharmacy. “REM sleep is a very active sleep where we have most of our dreams.

For now, while these findings indicate that many sleep-tracking devices do demonstrate promising performance for tracking sleep and wake, don’t start obsessing over your sleep data. Getting so caught up in the quest for 'perfect' sleep can actually further disrupt your shuteye; scientists have deemed this 'orthosomnia' (it’s not an official medical diagnosis, but, in the age of ubiquitous data, it’s another way metrics mess with your head).

These devices are merely meant to provide you with information that might inform your habits and help you spot problems. 'People who sleep well don't think about it,' says Peters. So if you wake up generally feeling refreshed, you probably don’t need a sleep tracker to give you any more information. But if you aren’t sleeping well, 'it is possible that sleep tracking may be the first step to engaging in helpful ways to optimise sleep,' he adds.

Just paying attention to trends and patterns in your sleep data may point to underlying sleep issues, such as sleep apnea. 'If someone is sleeping poorly, and the data supports this experience, it may lead to an evaluation by a board-certified sleep physician, and, with additional assessment, these problems may be resolved,' says Peters.

Just remember, wearing a sleep tracker isn’t going to do you any good if you aren’t doing the actual work to get a better night’s sleep, such as going to bed and waking up at a consistent time every day, working out during the day, avoiding caffeine and screen time before bed, and reserving your bed for sleep only. Unfortunately, that discipline and willpower need to come from you.
