"Adding alcohol simply adds to this impairment." 6. "We know from numerous studies into driving and sleep deprivation that lack of sleep triggers the same decline in performance as alcohol," says Dr Stanley. When men were asked to perform tasks under the influence of sleep deprivation and alcohol separately, then with both combined, reaction times, accuracy and speed suffered in each situation - but were significantly worse when alcohol and tiredness were combined, according to a study published in the journal Psychopharmacology. "It's been estimated that a unit of alcohol drunk when someone is sleep deprived will have the same effect on performance as three units consumed when someone is fully rested," says Dr Stanley. Finally, one way the body controls pain is via signals sent down from the brain, which inhibit pain sensations - it's possible that, during sleep deprivation, this descending pathway is weakened for some reason. "We also know that levels of inflammatory chemicals involved in pain are raised after a poor night's sleep. "Sleep loss lowers mood and, in a low mood state, people are more likely to be looking for pain and be more aware of it. "We're still trying to unpick why, but there are some theories," says Professor Nicole Tang, a health psychologist who specialises in sleep and pain at the University of Warwick. Studies have also shown those with chronic pain say their symptoms are worse when tired. In trials published in May from the Norwegian Institute of Public Health, those with insomnia were more likely to remove their hand earlier than those sleeping well. Aches and pains SEEM worseĪ common test for pain tolerance is to see how long someone can keep their hand in cold water. said they could spot when people were tired just by changes in the way they pronounced certain letters.Īfter depriving students of sleep, they compared their speech with people who'd rested well and found distinct differences in pronunciation - Ps became Bs, Ts sounded like Ds, and Ks more like Gs. Experts at Pennsylvania State University in the U.S. When you do formulate words, you may find yourself tripping over your tongue. "Co-ordinating the musculature of the mouth and tongue to form speech is quite a complicated task, and we don't manage it as effectively when we're tired." Professor Kevin Morgan, director of the Clinical Sleep Research Unit at Loughborough University, says: "This reflects the slowing and dulling of brain activity that occurs during sleep deprivation. This is because the muscles in the throat that govern the sound of our voice are not as well controlled when we're tired. Spending a few thousand dollars on a mattress might seem needlessly splurgy, but you can't put a price on luxurious rest.It's not just yawning that'll give tiredness away: sleep experts say a 'tired' voice tends to sound flat and monotone. (Eagle-eyed readers might notice that some previous winners we've crowned there have cropped back up on this list, too.) Because you deserve the best in R&R-whether that's a gentler alarm clock, a deliciously soft set of sheets to tuck you in at night, or a truly lavish pair of slippers. There's so much great new sleep gear rolling out these days that we thought it deserved its own spotlight beyond our yearly Home Awards. Now, for our first-ever GQ Sleep Awards, we're assembling the results of our lounging here, a small village of sleep essentials that'll help you hit the REM cycle expediently. We've whiled away the hours conked out on a number of new top-of-the-line mattresses, tested all the cozy fixings that cover and wrap around your bed, padded around in some of the swerviest of sleep garments, and tinkered with all the latest tech enhancements that accent our nightstands and get us out of bed in the morning. Thankfully, over the last couple years of mostly being cooped up at home, we've had ample opportunity to shuffle around our living arrangements, find what soothes us, and zero in on the stuff that makes winding down for the night that much easier. One of life's simplest pleasures is a blissful seven-something-hours of slumber, but between the news cycle, the state of our indoor air, mounting stress levels, the particularities of an aging body, and everything else, you may not be getting the most restful sleep of your life.
