Healthy sleep is critical for everyone, since we all need to retain information and learn skills to thrive in life. But this is likely part of the reason children—who acquire language, social, and motor skills at a breathtaking pace throughout their development—need more sleep than adults. While adults need 7-9 hours of sleep per night, one-year-olds need roughly 11 to 14 hours, school age children between 9 and 11, and teenagers between 8 and 10.During these critical periods of growth and learning, younger people need a heavy dose of slumber for optimal development and alertness.
Millions of people are using smartphone apps, bedside monitors, and wearable items (including bracelets, smart watches, and headbands) to informally collect and analyze data about their sleep. Smart technology can record sounds and movement during sleep, journal hours slept, and monitor heart beat and respiration. Using a companion app, data from some devices can be synced to a smartphone or tablet, or uploaded to a PC. Other apps and devices make white noise, produce light that stimulates melatonin production, and use gentle vibrations to help us sleep and wake.
To set the record straight about being horizontal, Quartz spoke to one of the world’s most-talked-about sleep scientists. Daniel Gartenberg is currently working on research funded by the National Science Foundation and the National Institute of Aging and is also a TED resident. (Watch his talk on deep sleep here.) He’s also an entrepreneur who has launched several cognitive-behavioral-therapy apps, including the Sonic Sleep Coach alarm clock. All that with 8.5 hours of sleep a night.

Want help achieving and maintaining a healthy weight? Aim for eight hours of sleep a night. Research suggests that appetite-regulating hormones are affected by sleep and that sleep deprivation could lead to weight gain. In two studies, people who slept five hours or less per night had higher levels of ghrelin – a hormone that stimulates hunger – and lower levels of the appetite-suppressing hormone leptin than those who slept eight hours per night. So make sure getting adequate sleep is near the top of your optimum health checklist!
Postpone worrying and brainstorming. If you wake during the night feeling anxious about something, make a brief note of it on paper and postpone worrying about it until the next day when it will be easier to resolve. Similarly, if a great idea is keeping you awake, make a note of it on paper and fall back to sleep knowing you’ll be much more productive after a good night’s rest.
Scientists continue to learn about the function and regulation of sleep. A key focus of research is to understand the risks involved with being chronically sleep deprived and the relationship between sleep and disease. People who are chronically sleep deprived are more likely to be overweight, have strokes and cardiovascular disease, infections, and certain types of cancer than those who get enough sleep. Sleep disturbances are common among people with age-related neurological disorders such as Alzheimer’s disease and Parkinson’s disease. Many mysteries remain about the association between sleep and these health problems. Does the lack of sleep lead to certain disorders, or do certain diseases cause a lack of sleep? These, and many other questions about sleep, represent the frontier of sleep research.
Cognitive behavioral therapy (CBT) usually focuses on discovering and changing the thoughts or feelings that trigger depression and stress but it can be a natural insomnia cure, too. Research has found that CBT can retrain your body and mind for faster, deeper sleep. In a Harvard University study of 63 insomniacs, CBT was more effective than prescription sleeping pills; it cut the time it took for participants to fall asleep in half and improved sleep quality by 17 percent. You can practice CBT at home, too. The National Sleep Foundation recommends keeping a sleep diary of when you go to bed and wake up, as well as banishing daytime naps. Instead, adopt a regular sleep schedule; that means going to bed and waking up at the same time every day.
Night shift workers often have trouble falling asleep when they go to bed, and also have trouble staying awake at work because their natural circadian rhythm and sleep-wake cycle is disrupted. In the case of jet lag, circadian rhythms become out of sync with the time of day when people fly to a different time zone, creating a mismatch between their internal clock and the actual clock.
You know a good night’s sleep is the key to a happy and well-rested tomorrow. And getting enough shut-eye can help you drive more safely, maintain a healthy weight, and even lower your risk for heart disease and diabetes. But if you’re stuck in a cycle of tossing and turning—and then start stressing about the fact that you’re tossing and turning—it's all too easy to feel frustrated. Not so fast: With these tips you’ll be snoozing within minutes of your head hitting the pillow.
