Temperatures are dropping and with the cooler weather comes more colds, the flu, and other sicknesses that put a serious damper on your holiday plans. No one wants to be cooped up on the couch with a runny nose all winter long, but sometimes it seems impossible to avoid.

But there's good news boosting your immune system can help you avoid getting sick, even in the chilly winter months. Here are a few easy ways you can keep your health in check over the holidays (and throughout the year):

1. Stay hydrated

Nothing keeps your immune system in check like drinking tons of water. According to Mind Body Green, you should add a slice of lemon for a little vitamin C if you want an extra boost.

2. Get enough sleep

Its hard to get enough sleep, especially during the holidays when you just want to stay up all night and watch Hallmark Christmas specials (please tell me Im not the only one). But youre more prone to sickness when you dont sleep, so aim for at least seven or eight hours every night. Your body will thank you.

3. Get some good bacteria

Adding bacteria to your diet might seem like the last thing you want to do when youre avoiding sickness, but good bacteria can save your immune system. Mind Body Green recommends eating foods like yogurt, miso, kefir and raw sauerkraut to get those great probiotics through your diet, but if you want even more good bacteria, you can get probiotics in supplement form.

4. Relax and de-stress

When youre stressed, your immune system takes a hit. Chronic stress kicks the immune system into low gear, leaving you more susceptible for illness. With finances, family, planning and other circumstances, the holidays can be a stressful time ... and when youre stressed, its easier to get sick. So take a few minutes a day to really relax. Meditate, exercise (if that relaxes you), do some yoga or take a walk. Keeping your mind healthy will keep your body healthy.

5. Eat as healthy as you can

The holidays really are the hardest time to eat healthy because of all the treats and comfort foods everywhere you look. You dont have to completely cut yourself off from the yummy goodies, but eating whole foods will help you stay healthy. Plus, by eating lots of vegetables, fruits and lean proteins, youll avoid needing to lose weight gained through all the festivities.

6. Keep everything clean

It seems like everyone is sick this time of year, so its important to keep your hands, your workspace, home and other shared areas nice and clean. Germs can spread super easily, so keeping everything sanitary can help avoid that. Encourage your family to wash their hands often and be sure to wipe down commonly used items like doorknobs, remote controls and phones.

7. Stick to an exercise routine

Exercising isnt everyones favorite thing to do, but it really helps your immune system stay super strong (according to WebMD). Getting your blood pumping and your endorphins moving will help you stay healthy all season long.

When you actively try to keep your immune system strong, youll have a happier, healthier life ... Did we miss any other ways to stay healthy through the winter months? Let us know in the comments!
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.
