Getting enough sleep is crucial to your physical and mental well-being. Yet, lack of sleep is something many of us experience. New findings published in the American Journal of Industrial Medicine state that 1 in 7 adults have difficulty falling asleep, while 1 in 6 adults have trouble staying asleep. There can be several reasons for this, according to the Harvard Medical School. These include poor diet and lack of exercise, along with sleep disorders such as sleep apnea.However, one major issue is stress. According to experts from Johns Hopkins, about 44 percent of adults claimed that stress lead to one or more sleepless nights. While many factors can cause stress in our lives, such as money, health, and relationships, recent findings indicate that job stress is causing some U.S. adults to sleep poorly.How No Sleep Impacts WorkHaving a stressful job is nothing new. Around 65 percent of working adults in the U.S. consider their jobs a form of stress in their lives, according to the Occupational Safety and Health Administration (OSHA). This stress can be harmful to an employee's physical and mental health, especially if they arent getting enough sleep.According to the new study, lack of sleep was associated with hypertension, cardiovascular disease, obesity, and premature death. The study authors also noted that workers with little sleep performed poorly at their jobs, and even led to some workplace injuries.What is Job Strain?The study characterizes job strain as high job demands with little job control. Job demands can include work overload, repetitive tasks, burnout, and role conflict. These characterizations come from Karasek's JobDemandControl model, which the researchers used to analyze their data.Researchers analyzed data collected from the last nine years through the Midlife in the United States (MIDUS) study and ranked study participants based on four different sleep-related disturbances.These disturbances include trouble falling asleep, waking up in the middle of the night and not being able to fall back asleep, waking up too early and not being able to fall back asleep, and feeling exhausted during the day, no matter how much sleep they got.The results indicate that higher job stress leads to more sleep disturbances over time.Our findings also suggest that the continuous formulations of job strain demonstrate better model performance with consistent and robust results, offering empirical evidence for future psychosocial occupational health research in the United States, said the first author, Yijia Sun, an MS candidate at the University of California, Los Angeles, in a press release.Improving Job StrainWith the study results, the authors are pushing for workplace changes or interventions to reduce stress.Strategies such as redesigning workloads and promoting worker autonomy could play an important role in improving sleep health and workers well-being, said corresponding author Jian Li, MD, PhD, a professor of Work and Health at the University of California, Los Angeles, in the release.Sleep is crucial to your health and may need to take precedence in certain situations. If stress is keeping you awake at night, there are some methods that may help you fall asleep and stay asleep.According to Johns Hopkins, gentle breathing exercises can help your body and mind relax before bed. You can also practice tai chi or yoga to help remove stress and tension from your body. Cutting back on alcohol and caffeine intake can help you feel less restless as you try to sleep, along with staying physically active.Try putting your phone and other devices away an hour before going to bed and set boundaries with your working hours. Dont answer the phone or respond to emails after a certain time. Prioritize sleep to prioritize your health.

A new study suggests that scientists could glean hints with a little help from the cosmos.Muons, subatomic particles that are like heavy versions of electrons, could reveal the atmospheric pressure within a thunderstorm and resulting tornado, researchers report in a paper accepted inPhysical Review D. The particles are produced by cosmic rays, which are an assortment of high-energy particles from space, including protons. When cosmic rays careen into the atmosphere, they produce muons that rain down on Earth including through tornadoes.

Marvel Rivals will soon kick off Season 1: Eternal Night Falls on January 10, and it wouldn't be a proper season start without a wide-range of balance changes to spice up the game's still in flux meta.In a blog post, developer NetEase outlined some of its philosophy in regards to the game's upcoming buffs and nerfs, stating it looked to adjust certain heroes in the name of "enabling a broader roster to partake in more intricate gameplay, ensuring a richer, more engaging, and diverse gaming experience for all." It outlined a number of different team compositions and strategies players are employing, and overall seems happy with what it calls a "vibrant diversity of lineups." That lineup is certain to change with the addition of the Fantastic Four this season, with heroes Mr. Fantastic and the Invisible Woman joining the roster at the season's start. As for the changes themselves, there are a number of buffs and nerfs to heroes in each role, with a significant number of changes to Duelist heroes. Popular damage dealers Hawkeye and Hela are being brought down a peg, with Hela having her health slightly decreased while Hawkeye will no longer be doing quite as much damage at longer ranges. On the flipside, Black Widow (one of the game's least-picked heroes according to NetEase), is getting a number of buffs. Moon Knight's ultimate ability will be more effective in Season 1, while Psylocke's will be a little less effective as it will have to cut through enemy shields as well. Storm is getting much-needed buffs, with increased projectile speed and damage, as well as more bonus health upon finishing her ultimate ability. Winter Soldier, another popular Duelist pick, is losing a little damage but gaining more survivability.Continue Reading at GameSpot

The Lenovo Legion Go S will become the first PC handheld not named Steam Deck to run on Valve's SteamOS when it launches this May. On paper, the $500 handheld is more powerful than the Steam Deck. That said, it doesn't have an OLED display or trackpads, so you'll have to weigh the pros and cons of the Steam Deck vs. Legion Go S to make your choice.If you want a handheld running on SteamOS, that is. If you're interested in a Windows portable, you can get the Legion Go S sooner. Slated to release in the coming weeks for $730, the high-end Lenovo Legion Go S with Windows has double the RAM and storage space as the SteamOS edition and is available to preorder at Best Buy. Lenovo Legion Go S (Windows Version) $730 | Releases February 14 At CES 2025, Lenovo said the Windows version of the Legion Go S would be available this month, but Best Buy's listing has the new handheld marked for February 14.The Legion Go S is fitted with the new AMD Ryzen Z2 Go chip, 32GB RAM, and a 1TB SSD. It has an 8-inch 1920 x 1200 LCD display with 120Hz variable refresh rate. Other features include adjustable RGB light rings around the analog sticks, two back buttons, one trackpad, and a pair of levers on the back that modify trigger tension.Unlike the original Legion Go, this one doesnt offer detachable gamepads or a kickstand, opting instead for a solid, streamlined design built specifically for handheld play. Lenovo increased the battery capacity from 49.2Wh to 55Wh with the Legion Go S.Lenovo will also launch a second Windows configuration in May for $600. This lower-priced model has 16GB RAM instead of 32GB. Preorders aren't live for the $600 model just yet. Preorder at Best Buy Lenovo Legion Go S (SteamOS Version) $500 | Releases in May The SteamOS edition isn't available to preorder yet, but it'll launch in May for $500. The Legion Go S will be the first third-party handheld that uses Valve's Steam Deck operating system. This model will receive the same updates as Valves Steam Deck. That means you wont have to worry about Valve abandoning SteamOS on the Legion Go S, as the team is treating SteamOS as a unified platform regardless of which handheld youre playing on.While it retains the Ryzen Z2 Go chip and the 8-inch 1200p display, the SteamOS edition is limited to 16GB RAM and a 512GB SSD. You can upgrade your SSD or expand the storage capacity via microSD.For comparison, the Steam Deck starts at $399 for the 256GB model with a 7-inch LCD display. The 512GB model with a 7.4-inch OLED display costs $549, and the 1TB OLED edition goes for $649.If you opt for the Legion Go S, you'll get a faster processor and a larger 8-inch screen with higher resolution--1200p compared to the Steam Deck's 800p resolution. That said, the Legion Go S uses an LCD panel, whereas the 512GB and 1TB Steam Deck models have better OLED screens.Lenovo went with a more conventional control layout with offset sticks, while the Steam Deck's two sticks, D-pad, and face buttons are essentially aligned. The layout admittedly looks odd, but the Steam Deck is a lot comfier than it looks. Valve's handheld has four remappable back triggers, while Lenovo's new handheld only has two. The Steam Deck also has two large trackpads, whereas the Legion Go S has one small pad. Adjustable trigger tension is unique to the Legion Go S.With these differences, it'll be interesting to see how the Legion Go S stacks up against the Steam Deck.
