Was verursacht Schlafprobleme bei Amerikanern?

According to a new WebMD survey of 2,000 people, many Americans are not getting as much good sleep as they need, even though they spend enough time in bed. Over 7 out of 10 respondents (73%) rated their sleep in the previous month as „good“ or „very good.“ And 63% spent at least 7 hours in bed every night. (Experts recommend that most adults need 7-9 hours of sleep each night.) However, only a little over a third of respondents (36%) reported actually sleeping for at least 7 hours. On average, they only slept 5.7 hours per night – much less than what is necessary for optimal health.

Sleep is often overlooked, but getting less than 7 hours of sleep per night can increase the risk of conditions such as heart disease, stroke, diabetes, mood swings, and obesity. Estimates suggest that sleep issues cost Americans about $16 billion annually in medical bills. „The impacts of poor sleep are widespread,“ says Dr. Marri Horvat from the Cleveland Clinic Sleep Disorders Center. „Depending on the cause, it can affect a variety of organs, from the skin to the heart and brain.“ It is also associated with the risk of premature death.

The WebMD survey used a nationally representative sample of adults, meaning the group closely matched the U.S. population in terms of age, gender, race, and geographic location. The survey revealed that people struggle with both falling asleep and staying asleep. The average time spent in bed was 7.61 hours, with individuals being awake for almost 2 hours on average after going to bed. Here are some of the reasons for this:

**Time to sleep:** Doctors say most adults without sleep problems should be able to fall asleep about 20 minutes after hitting the pillow. However, 43% of people in the WebMD survey reported taking more than 30 minutes to fall asleep after going to bed. Only 23% fell asleep in 20 minutes or less. The average time to fall asleep was 29.8 minutes.

**Waking up at night:** Only 10% of respondents stated they never woke up in the middle of the night in the 30 days before the survey, and 16% reported this happening on more than 20 nights. On average:
– People reported waking up almost nine times a month at night.
– They woke up early and couldn’t fall back asleep for 7.3 nights.

Despite sleeping fewer hours, why do some report feeling well-rested? This is likely because people define sleep quality in different ways, says Horvat. „Some feel that the duration of sleep improves or worsens their quality of sleep, others believe it’s about the ability to stay asleep, and still others look at their daytime symptoms to determine if they’ve slept well,“ she says.

The reasons for not getting enough sleep vary from minor causes like a barking dog to serious issues like sleep apnea. **Sleep disorders** were common among survey participants: 17% had insomnia, 14% had obstructive sleep apnea, 13% had restless legs syndrome, and 8% had either narcolepsy or hypersomnia. These conditions are treatable, so consult your doctor if any of them affect your sleep quality.

Factors like obesity, other health conditions, and waking up to urinate during the night can also impact sleep quality. It is important to prioritize sleep and implement good sleep hygiene practices. If sleep problems persist for more than a month or affect your daily life, it’s essential to seek medical advice.
