We all feel better when were sleeping well, but did you know that good sleep habits can impact everything from your marriage to your weight loss goals? Here are just a few ways high quality sleep supports other aspects of your life.

Sleep improves your relationships

If youre someone who is unbearably cranky after a sleepless night, this wont come as a surprise to you, but well-rested people tend to argue less and have better relationships.

Numerous studies show that sleeping well increases relationship satisfaction and leads to longer, happier marriages.

If you and your spouse are in the midst of those pesky no-sleep baby years, dont worry. It can help to simply acknowledge that your lack of sleep is a big part of any relationship problems youre having. By the time our second (wakeful) baby came along, my husband and I were bickering, a lot. We simply agreed that anything mean we said to each other when we were exhausted, didnt count. It wasnt a perfect solution, but it helped.

Sleep flushes out brain toxins

Amazing changes happen in your brain when you sleep, and were not just talking about brain activity. There is evidence that there's a certain amount of structural change in the brain during a good nights sleep.

Research indicates that the space between brain cells seems to increase while were asleep, allowing the brain to flush out toxins that have built up during the day. This means sleep is cleaning our brains. No wonder we feel more clear-headed after a good nights sleep.

Sleep makes you thinner

According to an article in Womens Health, there are several reasons youll lose weight faster if youre sleeping well.

Mental benefits of sleep include that clearer brain weve already mentioned, which can support healthier decision-making, and, of course, restful sleep tends to leave us with more energy to exercise. But theres also evidence that sleep has physical effects, helping support a healthy metabolism and regulate hormonal activity, allowing you to burn more calories.

Sleep will stop you making mistakes

Any idea what the Exxon Valdez oil spill, the explosion of the Challenger space shuttle, and the nuclear disaster at Chenobyl all have in common? Sadly, they were all at least partially attributed to human error caused by lack of sleep.

In her book, Thrive, Arianna Huffington goes so far as to claim that:

The most basic shift we can make in redefining success in our lives, has to do with our strained relationship with sleep.

She goes on to quote Bill Clinton, who apparently once admitted,

Every important mistake Ive made in my life, Ive made because I was too tired.

Good decision making is vital to a happy, prosperous life, and almost every decision we make could probably be made a little better by getting a good nights sleep before making it.

Sleep makes you look better

The idea of beauty sleep is far from a myth. Most of us instinctively feel that we look brighter and better after a good nights sleep, and were not wrong.

Sleep has amazing benefits for our skin, in particular, and because it supports our general health and wellbeing, consistent high-quality sleep will usually make us look healthier and happier.

Sleeping well is about so much more than feeling well-rested in the morning. Its worth working on your sleep hygiene and making any changes you need to get a better nights sleep. It could help with everything from weight management to marital harmony.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
