Learn prevention tips and treatments for insomnia from pharmacologist Joe Graedon of the popular public radio show The People's Pharmacy.
In order to fall asleep, the human body produces melatonin, a hormone created in the pineal gland. Melatonin allows the body to relax enough to sleep, allowing it to follow the natural circadian rhythm. However, some environmental factors can interfere with the production of melatonin and make falling asleep naturally a highly difficult task. One such factor is blue light.
Why is light such a crucial factor? Before technology and electricity, the human body relied upon environmental light to determine when it was time to sleep and when it was time to wake up. In today's world there are alarm clocks, cell phones, and other devices that dictate when it is time to get out of bed, but the body has yet to adapt to these technological changes. Despite the fact that you may have depended upon an alarm clock for your entire life, your body is still capable of matching its sleep cycle to the natural cycle of the environment.
Blue light is a part of the light spectrum that is especially visible during the day, making its appearance a cue to the body to wake up. No matter how tired you are, your body may be limited in its production of melatonin if you are exposed to blue light. It follows, then, that avoiding blue light before going to bed is a great way to allow your body to produce the natural levels of melatonin that it needs to fall asleep. Read more
As you go about your hectic lifestyle, one thing that you must be sure that you're not shorting yourself on is a sound sleep. If you're working out hard in the gym, without that proper night's rest each evening, you're going to really struggle to keep up with your recovery and progress.
In addition to this, those who aren't sleeping well throughout the night are more likely to see elevated levels of cortisol in their body, which will then encourage belly fat accumulation. If a lean midsection and a healthy rate of muscle building are two of your main priorities, you definitely want to look into how to sleep better. You’ve come to the right place.
What you eat will have a big influence on the quality of your sleep. You can easily sleep better by making a few changes and being sure to include foods that promote rest. Note, however, that you should not eat these foods immediately before going to bed, as that can keep you awake due to the increased blood flow to the digestive system; eat them one to two hours before you plan to turn in for the night. This will allow the heaviest part of digestion to take place and also give the sleep-enhancing effects a chance to kick in.
Let's have a quick look at the top foods you should consider if you want to sleep better. Read more
A wealth of research is pointing to an ever increasing problem that is shown to increase our risk of cancer. The problem is with light sources in the bedroom at night when most people are asleep. Many of the critical biological functions carried out by our body during sleep are dependent on circadian rhythms and are disturbed by the smallest amount of light from devices such as iPods, laptops, electronic readers and television. Information provided by the journal Cancer Genetics and Cytogenetics shines a light on the importance of sleeping in a totally dark room to lower cancer risk.
Researchers have been able to show that a single light emission during sleep is enough to disrupt the circadian rhythm of the sleep cycle and alter normal cellular division. The body requires 7 to 9 hours of uninterrupted sleep with no light distraction each night to complete the repair and regeneration functions essential to maintain optimal health. Read more
Perhaps nothing is scarier than receiving a diagnosis of cancer, even if it's caught early and therefore treatable. Theories abound on ways to prevent cancer and even help heal the body during treatment, from changing one's diet to managing stress and engaging in mind-body activities like meditation and deep breathing.
But what about paying attention to sleep? Have there been any connections made between sleep and cancer?
There's no question that getting restful sleep is beneficial for both healthy people and those battling cancer, but now we have evidence that people who sleep less than six hours a night could be more likely to have dangerous polyps in their colon or rectum compared to better-rested patients. The study, which was published by the journal Cancer in October, reflects the first time anyone has ever found a link between sleep duration and risk of polyps, which are tied directly with the risk for colon cancer.

Ever wonder why some people breeze along on four hours of sleep when others can barely function? It may be in our genes, according to new research and an accompanying editorial published in the October 26, 2010, print issue of Neurology®, the medical journal of the American Academy of Neurology.

Sleep is one of the great mysteries of life. Like gravity or the quantum field, we still don’t understand exactly why we sleep – although we are learning more about it every day.
We do know, however, that good sleep is one of the cornerstones of health.
Six to eight hours per night seems to be the optimal amount of sleep for most adults, and too much or too little can have adverse effects on your health.
Sleep deprivation is such a chronic condition these days that you might not even realize you suffer from it. Science has now established that a sleep deficit can have serious, far reaching effects on your health.
For example, interrupted or impaired sleep can: Read more
Hopefully the cherry growers and distributor industry won't publicize this to bring more threats from the FDA upon them, but a pilot study by research scientists showed that tart cherry juice reduced insomnia with older adults. The study was conducted by researchers from two universities at the VA Center of Canandaigua, and the findings were published in the June 3, 2010 issue of the Journal of Medicinal Food. Read more
Dust mites are everywhere. They are true survivors, able to make it in virtually all climates and at any altitude. They thrive, however, in our homes, especially bedrooms, enjoying the humidity generated by all the breathing, perspiring, and drooling we do at night and feeding on all the skin flakes we produce. For these tiny creatures, we’re living, breathing humidifier-refrigerator-landlords who charge extremely competitive rates. Why wouldn’t they infest us?
In the last couple weeks we’ve taken a look at sleep posture, how to improve it, and modern bedding. Today we’ll take a closer look at your mattress, investigating what may be lurking inside and what you can do about it. Read more
Yesterday, I posited that it’s not so much the bedding that matters in making for rejuvenating, nourishing sleep, but rather our sleeping position/posture. Man is the supreme adaptor, having proven himself capable of surviving in just about any natural environment, no matter the climate, topography, and available selection of edibles – and our bedding is no different. Of course, there is a limit to our adaptability. We couldn’t survive in the Antarctic or get a good night’s sleep in a mud pit. Thriving in the current food environment is definitely doable, but, as you well know, it takes a lot of effort to make it work. Luckily, we aren’t dealing with hydrogenated mattresses or high-fructose pillows, so the bedding situation isn’t so dire.
You can keep it pretty simple, in fact: if you’re getting good, pain-free sleep already, hacking isn’t necessary. Just keep doing what you’re doing and keep the bed you’ve got. (Keep reading, though.)
If you’re waking up with pain, though, we should reevaluate. Pain usually indicates an improper sleeping position, and that’s the easiest thing to fix (rather than buying an entirely new bed), so let’s look at some other options. Read more
Sleeping on the job used to be grounds for dismissal. But now, years after Cornell University psychologist James Maas coined the term "power nap," companies are beginning to embrace the practice. Today, Nike and Deloitte Consulting are among those that encourage employees to add a midday snooze to their to-do lists. Sleep scientist Sara Mednick applauds this trend. Mednick, a researcher at the Salk Institute for Biological Studies in San Diego and author of the new book Take a Nap! Change Your Life (Workman Publishing), says napping can enhance productivity.
What are the main benefits of napping?
Research on sleep deprivation shows that even at six hours a night, there are all sorts of changes in the body. Insulin rises to pre-diabetes levels. There's an increase in heart disease. Without sleep you don't learn. My research shows that people deteriorate during the day. It's difficult to sustain productivity. Naps can add back to the sleep you're deprived of at night. And a nap enhances productivity even if you have enough nocturnal sleep. Read more
It may not make you popular with your boss but a snooze in the middle of the day dramatically boosts your brain power.
Medical researchers have shown that the power naps favoured by Winston Churchill, Albert Einstein and Margaret Thatcher not only refresh the mind, they also make people smarter.
They found snoozing for just one hour in the day is enough to increase the brain's ability to learn new facts in the hours that follow. Read more
For women, lack of sleep is so common that the standard reply to ‘How are you?’ is: ‘Shattered!’ But a growing body of evidence indicates that chronic tiredness isn’t just affecting our ability to function well - it’s also making us fat.
Around 60 per cent of British adults are overweight or obese, and research suggests that the cause may not be overeating or lack of exercise, but sleep deprivation.
As you will see, the reason that singer Jennifer Lopez looks ten years younger than she is may be due to her ability to get eight hours of sleep a night. Read more
You can lose weight without changing what you eat or doing one minute of exercise! It's a bold claim. And don't get me wrong: Nutrition and exercise are important! But there's another key to weight loss -- and most people don't even know about it. It's sleep.
In fact, besides eating whole foods and moving your body, getting enough sleep is the most important thing you can do for your health. On the flip side, sleep deprivation makes you fat -- AND leads to depression, pain, heart disease, diabetes, and much more. Read more
It's a universal truth: When you're in your 20s, you can stay out all night and look fresh the next morning. Unfortunately, as we age, lack of sleep affects us more deeply and shows more prominently on our faces -- lackluster complexions, dark circles, fine lines and, in more extreme cases, rashes and eczema.
Progressive loss of cellular water may be one reason sleepless nights affect our skin more visibly as we age, says board-certified dermatologist Dr. Howard Murad. Water retention is key to keeping skin moisturized and supple, which can translate to fewer lines and a smoother complexion. Read more
