Worried youll have to cope with lower back pain forever? Here are the best exercises to help you find relief. - photo by Eric Brown
Back pain is a very common ailment. So its no surprise that, as chiropractors, were often asked, "What can I do to relieve my lower back pain?"

Luckily, there are some helpful exercises that can help counteract the problems and behaviors that lead to lower back pain.

Here are the top five lower back pain exercises we recommend. If you experience pain while doing any of them, stop immediately and seek medical advice.

1. Back extensions

If youve ever done yoga, you might know this one as cobra pose. Back extensions stretch the spine and can help relieve back pain.

Just lie on your stomach and prop yourself up on your elbows. Try to keep your neck long and shoulders back -- this will help lengthen your spine.

Push down on the floor with your hands to push your back up as far as feels comfortable. Youll also feel a stretch in the stomach muscles. Hold the position for five to 10 seconds while breathing normally. Repeat the exercise 10 times.

2. Abdominal contractions

Lie on your back and bend your knees. Keep your feet hip-width apart. Try to relax your body, especially the neck and shoulders.

When you exhale, draw the muscles of your pelvis and lower abdominals upward. Hold this gentle contraction, but continue to breathe from your abdomen. After five to 10 breaths, relax your muscles. Repeat five times.

You can also try some mild partial crunches for a more intense workout. Just avoid overdoing it with something like sit-ups, so you dont aggravate your existing back pain.

3. Bridge pose

Bridge pose can do a great job of relieving lower back pain.

Lie on your back with knees bent, your feet hip-width apart. Inhale, and as you exhale, lift your hips off the floor. Try to get your shoulders and knees in a straight line. To avoid overarching, tighten your abdominal muscles during the pose. Lower to the ground as you breathe.

As you build strength and flexibility, you can increase your repetitions. The Mayo Clinic recommends doing this exercise five times a day.

4. Lower back rotation

This rotation will stretch out your spine and help relieve lower back pain.

Lie down on your back and keep your knees bent. Relax your upper body. Roll your knees to one side, then your pelvis. Try to keep both shoulder blades on the floor. Turn your gaze over the opposite shoulder.

After 10 seconds, return to the starting position. Repeat on the other side. Do the stretch two or three times on each side.

5. Exercise ball

If youre ready to increase the intensity of your lower back exercises, use an exercise (or swiss) ball.

The AAOS recommends using an exercise ball for lumbar stabilization exercises.

Lie down on your back with your knees bent. Rest your calves on the ball. There are a few exercises you can do in this position:

  • Slowly lift one arm over your head, then lower it. Lift the other arm, and switch back and forth.
  • Slowly straighten one knee vertically. Relax, and switch sides. Alternate left and right.
  • Do the two previous exercises together by straightening one knee and raising the opposite arm overhead together. Alternate sides.
  • Slowly (walk) the ball forward and then backward with your legs.
Keep moving

According to NINDS, fitness level can have an impact on how much people suffer from lower back pain.

So while these five exercises are a great place to start in combating the problem, strengthening the back muscles overall may be the key to long-term relief.

Practice these exercises for your spinal needs, but also consider creating a routine of exercises to combat back pain before it starts, such as swimming, stretching and yoga.
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.
