Four in 10 Americans are so worried about the future they're losing sleep, according to new research. A new study of 2,000 Americans found 41% of people are up all night due to 'next day anxiety' — fearing the uncertainty of what tomorrow holds so much, it keeps them up at night. Nearly two-thirds (62%) of people struggle to fall asleep. Along with anxiety about the future, replaying the past day's events (37%), being too hot or too cold (31%) and having too much caffeine earlier in the day (28%), are all to blame for keeping people awake deep in the night. Several respondents even claimed other factors such as feeling uncomfortable, too itchy and having a fear of nightmares have also kept them up at night. For 101 respondents, dogs are to blame for keeping them up at night. By comparison, 77 respondents blamed their cats. More than a quarter of those Americans polled (27%) have been diagnosed with a sleeping disorder. The most common disorders among them are insomnia (45%), sleep apnea (44%) and restless leg syndrome (17%). Though 73% of Americans have never been diagnosed with a sleeping disorder, a third of them have spouses/partners that insist they have a sleeping disorder of some kind. Commissioned by mattress company Saatva and conducted by OnePoll, the survey dove into the sleeping habits (or lack thereof) of Americans. Results found people will wake up in the middle of the night an average of five times every week. And when they wake up, 63% of people will struggle to go back to sleep. Anxiety isn't always to blame for waking people up at night. From having cockroaches landing on their heads, having an orgasm in their sleep, rolling out of bed and slamming their head into a wall or even wetting the bed, Americans have had their sleep interrupted by a plethora of odd events. But the secret to getting great sleep and staying asleep, according to respondents, includes a little bit of wine, cannabis edibles, aromatherapy, reading, using a nasal rinse, finding and playing boring documentaries on tv and most importantly — finding a way to get comfy. People will rely on a lot of things to get comfy in bed. Top among them include a favorite pillow (54%) or blanket (50%), having the right mattress (38%) and having their partner next to them (28%). On average, Americans take 27 minutes to fall asleep. For more than a third (37%), falling asleep takes less than 15 minutes. For 11% of Americans, it takes over an hour. "I tell people that they have to view sleep as an activity and prepare for it, the same way they would if they were going to work out or play a sport," says Saatva CEO Ron Rudzin. He ticks off the list of things he has to do before he can sleep comfortably: "I make sure that the temperature of the room is right, it has to be extremely dark, I turn off all my electronics about 15 minutes beforehand, I take a warm shower before I go to sleep. I do the same preparation for sleep every single night," he says, "because I know how important it is." The survey also found nearly eight in 10 people (78%) have had dreams that felt real. These vivid dreamers say they have an average of nine realistic dreams per month. When asked to describe their realistic dreams, several respondents said they had vivid dreams of lost relatives, being back in school, being at work and being attacked by random animals or things. These types of realistic, stressful dreams seem to be on the rise, as well. Half of Americans report they have had more stress-related dreams this year than ever before. When asked to identify the source of their stress dreams, respondents said the current pandemic crisis and money woes are equally to blame (36%), while earlier events of the day also rank high as a stressor (32%). Several respondents say their stress dreams come from more unorthodox sources, like having a specific phobia, past traumatic experiences, not having their kids or family members nearby and even stress dreams of upcoming, anxiety-inducing events. "That's why it's so important to relax body and mind before trying to sleep, especially these days. It can be more than just keeping the bedroom a dark, quiet and cool space," according to the experts at Saatva, "Other stress-busting things to incorporate into your bedtime routine are gentle stretches, deep breathing or meditation, smelling lavender, even making a to-do list for the next day. If all else fails, you can always try a weighted blanket, which has been shown in lab studies to help people suffering from insomnia fall—and stay—asleep."
