You’ve probably seen countless ads for diet pill wonder products promising you can burn calories during sleep and even shed pounds while getting your zzz’s. Wouldn’t it be wonderful if it really was that simple? However, there is a fair amount of evidence to support the idea that it really is possible to do just that – given the right set of circumstances. The key is to set the stage to burn the maximum amount of calories at night.

Teens and Sleep

The debate about teens and sleep has been raging for many years. Scientific evidence suggests, however, that parents really should give their teens a bit of a break for sleeping in on weekends. It seems that growing teen bodies need a little more sleep than the average adult. More importantly, the average teen, 90 percent of teens according a recent Journal of School Health study, are not getting their daily recommend hours of sleep.

You know the type. You may even be one of them. They are the fortunate few who can sleep through anything. Bad weather. An early-morning rooster crowing. Things that go bump. You name it. It’s no problem for them. They seem to “miss out” on all the little things that keep other people up at night. Or, at the very least – the things that wake others up at night.

Sleep Cycles

Most people never think about sleep cycles until they begin feeling the impact of not getting an adequate amount of sleep. In fact, there are some people who only know of REM sleep because they hear about it in movies, read about it in books, or watch shows on  television that mention it. However, they have little knowledge of what it means or how different sleep cycles impact their mental and physical health and well-being.

The exact science behind why people dream is still a mystery, but recent research using computer technology now brings us closer to understanding dreams.

Functional Magnetic Resonance Image (fMRI) scans can essentially “see” our dreams by revealing visual images our brains have while we are dreaming. What’s more, a computer is able to predict what you are dreaming about while asleep based upon your brainwave activity, according to a new study out of Japan.

Lack of sleep can do more than make you grumpier than Oscar the Grouch. It can have an impact on your immune system, according to a study conducted by the Surrey Sleep Research Centre. Researchers found that poor sleep quality for just one week could impact hundreds of genes related to metabolism, response to stress, and our immune system, which helps to protect us from illness and disease.

For people who have trouble sleeping, snore loudly, are overly tired, or have chronic fatigue, often the first step to a diagnosis is an overnight stay in a sleep lab. If your doctor has ordered you to have an overnight sleep study (referred to as a polysomnogram) in a sleep center, here’s what you need to know about the experience.

You probably know that it’s advised to practice good hygiene to keep yourself healthy, and to help prevent the spread of diseases. But did you know that “sleep hygiene” plays an important role in getting the quality sleep that you need each and every night?

You’ve heard about synchronized swimming, but have you heard about synchronized sounds? Well, a new sleep study reveals that simply listening to your own natural brain rhythms in a synchronized fashion can help sharpen sleep.

Headed by Jan Born out of the University of Tubingen in Germany, sleep researchers found that during our deepest sleep, our brain’s electrical patterns present a slow oscillating-type rhythm.
