There may be a simpler and cheaper way to deal with infertility. - photo by Kelsey Robertson
One in eight couples have fertility issues. That is 12% of married women that either cant get pregnant or can't sustain a pregnancy. Of that 12%, a little over 11% will actually go see a fertility doctor, but fertility visits and treatments can cost thousands of dollars and take years to complete. For a simpler solution, just check your sleep schedule.

Both men and women need sleep to be healthy, but for women trying to conceive, it is crucial. Research suggests women need 7-9 hours of sleep a night but most women faced with infertility average only six hours of sleep each night! This lack of sleep affects more than whether or not you can function the next day; it can affect your ability to get pregnant.

How?

When we sleep our bodies are actively preparing for the next days work. During the sleep cycle key hormones are produced and secreted that regulate ovulation and conception. When we dont get enough sleep, our bodies cant properly replenish these hormones, specifically the key fertility hormones prolactin and leptin.

Prolactin

Prolactin is primarily known for allowing women to produce breast milk after birth, but high or low prolactin levels can also cause infertility. This hormone is secreted during sleep; without a normal sleep cycle prolactin levels can become irregular. Both high and low levels of prolactin are dangerous while trying to conceive.

High levels of prolactin may mean you are not ovulating during your menstrual cycle and low levels of prolactin may be detrimental to sustaining pregnancy.

Leptin

Leptin is commonly known as the Im full protein because it regulates your appetite, but it's also a key hormone in maintaining predictable ovulation cycles in women.

Leptin regulates the receptors in our brains that tell us when we are hungry and full and this key hormone is replenished while we sleep. A lack of sleep may cause overeating or an irregular diet, which in turn causes weight gain and an increase in leptin storage. This increase may lead to irregular periods. If too much leptin is produced, the chances of pregnancy are much lower and the risks associated with pregnancy are much higher.

If there is too little leptin production, the menstrual cycle will be irregular and may even be absent.

Sleep is also key in maintaining proper production and secretion of other key fertility hormones such as estrogen, progesterone, luteinizing hormone (LH) and follicle-stimulating hormone (FSH). The body is a sensitive tangle of systems, proteins and hormones that all need to work together and stay in balance to achieve optimal health and fertility conditions. And sleep is the key to maintaining this healthy balance.

Men need their sleep, too

Women do the brunt of the work once pregnant, but a lack of sleep for men can also affect a couples fertility. Men may not need quite as much sleep as women, but a solid eight hours of sleep each night is recommended. The REM cycle during sleep is very important for mens fertility. When the REM cycle is interrupted men may produce less testosterone. This drop in testosterone make it much harder to get pregnant.

-We all know sleep is important. It is important for our overall health and development and, now you know, it is just as important for fertility. Getting the proper amount of sleep may not cure a couples infertility, but it is worth a try. Its free and if it doesnt lead to pregnancy, it will at least lead to a healthier and happier life!
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.
