I Wish I Knew These Tips on Choosing the Right Light Bulbs for Eye Health Earlier

I Wish I Knew These Tips on Choosing the Right Light Bulbs for Eye Health Earlier

There is no doubt that the focus on reducing energy consumption in the past decade has led to the increased use of fluorescent light bulbs over conventional incandescent bulbs. While there are definitely benefits to having your home and office equipped with efficient CFL bulbs, new research suggests that overdoing it can lead to adverse effects on your vision.

Indeed, one study out of the Australian National University (ANU) in Canberra, Australia, found that overexposure to “cool” or “bright white” fluorescent bulbs in office buildings, markets, schools, and other commercial areas can lead to several vision-afflicting maladies.

They concluded that you are putting yourself at the greatest risk if you are exposed to this kind of lighting for 45 hours a week or more. Once you pass that threshold, you’re increasing your risk of acquiring not only cataracts, but diseases like pterygia, which causes a non-cancerous tissue to grow on the whites of your eyes, eventually obscuring your vision.

What is it that causes “cool” and “bright white” fluorescent bulbs to have this effect? It is the excess amount of UV radiation they emit, which equals or exceeds the amount contained within sunlight. If you spend enough time in this kind of light, which many people do (especially in office spaces), you increase your risk of causing “”irreparable damage to [your eyes],” according to this study. Many people are already at risk of developing cataracts as they age, and increased use of high UV fluorescent bulbs has only made the situation worse.

Indeed, one of the coauthors of this study, Helen Walls, states that “exposure to ‘cool white’ fluorescents for 45 hours per week throughout your working life may increase your risk of getting cataracts at age 50 by between 2 and 12 percent.”

Remember: this kind of damage is caused by indirect exposure to the light emitted by bright fluorescents. You probably increase your risk exponentially if you stare at them directly with your naked eyes. I add that because, while most of us are told not to look directly at the sun, we’re never really told not to look directly at a light bulb.

For an outline of the light bulbs you should avoid, light bulbs you should buy, and steps you can take to protect yourself, read on.

Light Bulbs To Avoid

  • High efficiency “cool” and “bright white” fluorescent bulbs. They usually emit a slightly bluish light along with copious amounts of UV radiation, and are often used in schools and offices.

Light Bulbs To Buy

  • Traditional incandescent bulbs.
  • “Warm white” fluorescent CFLs, which mimic the glow of an incandescent bulb while still being energy efficient. Additionally, they do not emit as much UV radiation as their brighter counterparts.
  • LED bulbs.
  • Halogen bulbs are also an option in special cases. They are bright enough for most tasks, do not emit UV radiation, and are only slightly more inefficient than CFLs.

For a look at how much these bulbs cost, check this useful site (this one is good too). Typically speaking though, LEDs are the most expensive but use the least amount of energy. Flourescents are much cheaper but not nearly as efficient as LEDs. Incandescents cost the least up front, but use the most energy.

Steps You Can Take

  • Don’t replace all of your incandescent bulbs at home with “bright white” fluorescents. As the researchers note in their study, this only increases the time that your eyes are exposed to excess UV radiation during the week.
  • Use natural lighting when you can, especially while at work. Most buildings have UV resistant glass installed, so the light filtered in through your window is healthier for you than the fluorescent light above you or on your desk.
  • If you work outside, wear sunglasses at all times.
  • If you work inside, consider purchasing glasses that protect you from UV light, such as these.

The main takeaway here is that you can drastically improve your eye health by taking a few precautionary measures both at work and at home. Trust me, your eyes will thank you as you get older!

11 Hidden Benefits of Using Oil Diffusers

11 Hidden Benefits of Using Oil Diffusers

Affordable, relaxing, and healthy, oil diffusers are gaining popularity with people everywhere due to their extensive benefits. Oil diffusers work through the simple process of oil diffusion, which uses heat to turn oil into a vapor that is then spread around a living space. Diffused oil can have several relaxation and health-related benefits, including safe scent-dispersion, mosquito and mold defense, stress relief, and more!

Read on for 11 hidden benefits of using oil diffusers.

1. Safe Scents That Make Sense

Unlike candles or air fresheners, oil diffusers release cleansing molecules into your air that work to purify it, not overload it with unhealthy chemicals. Electronic diffusers also do not pose the fire risk that candles do. Plus, they contain the added feature of interchangeability, which means you change oil types for different scents and health benefits.

2. Stress Relief

Several lab studies have confirmed that diffusing essential oils like lavender have been shown to reduce stress and help relieve anxiety in medical patients. Preliminary studies have also shown that oil diffusers can help alleviate symptoms of depression.

3. Improved Sleep

Diffused oil has relaxing properties that can help people of all ages fall asleep quicker and sleep more soundly. Electronic diffusers not only have the option to mix and match different oil blends (Try a lavender, Bulgarian rose, and Roman chamomile blend to help with insomnia), they also run at a gentle hum that helps relax an agitated mind. Many also come with an auto shut-off feature to help conserve oils once you have fallen asleep.

4. Appetite Control

Much like gum, oil diffusers can help stimulate the senses in a way that works to curb appetite. New research has shown that diffused peppermint oil can help curb appetite by inducing a satiety response within the body. Diffused peppermint oil has also been shown to increase energy.

5. Bacteria and Mold Killing

When essential oils are diffused in the air, they break down free radicals that contribute to the growth of harmful bacteria. Eucalyptus, thyme, and tea tree oils are especially good for this purpose. Diffused oil is also highly effective when it comes to combating fungal yeast threats, as the oil help makes the air inhospitable for yeasts such as mold. Pine and red thyme essential oils are best for combating mold.

6. Decongestion and Mucus Control

Ever tried Vick’s Vapo-Rub? Its decongesting powers come from active ingredients made from the eucalyptus tree. In principle, oil diffusers work the same way as Vapo-Rub, except they diffuse their decongesting vapor all around the room, not just on your chest or neck. Oil diffusers have been known to cure pneumonia in lab mice.

7. Mosquito Repellant

Nobody likes mosquitoes — but when the trade-off means using repellants full of DEET, a toxic chemical that can be especially harmful to children, mosquito control can often seem like a lose-lose. However, scientists have shown that oil diffusers can be used as a safe and highly effective mosquito repellant. Studies have shown that a diffused oil mixture containing clove essential oil and lemongrass essential oil repelled one type of Zika-carrying mosquito, the Aedes aegypti mosquito, at a rate of 100%.

8. Pain Relief

While applying oils directly to areas of your body may be the most effective way to alleviate pain, diffusing essential oils can also be an effective means of pain relief. When we inhale healthy essential oils, they enter our blood stream and can help internally relieve persistent pain from headaches, overworked muscles, and sore joints.

9. The New Anti-Viral

Research into the anti-viral effects of oil diffusion is now just gaining steam. A recent study showed that star anise essential oil was proven in medical experiments to destroy the herpes simplex virus in contained areas at a rate of 99%. Another study showed the popular DoTerra oil blend OnGuard to have highly-effective influenza-combating powers.

10. Improved Cognitive Function

Diffusing essential oils has also been shown to improve cognitive function. Many essential oils have adaptogenic qualities, which can work twofold in soothing us when we’re stressed, and giving our bodies a pick-me-up when we’re feeling down or sluggish. By working to level out an imbalanced mood, diffused oils also help us to focus. There are also several essential oils which have been shown to help balance the body’s hormones. With prolonged use, these oils can work to repair the underlying causes responsible for hindering cognitive function.

11. Money Saving

With ten clear benefits of oil diffusers already outlined, there is one more that should now be obvious: using an oil diffuser will help you to save money. As an anti-viral, bug repelling, and stress-relief solution rolled into one safe product, an oil diffuser used with the proper oils will save you money on products you might otherwise be buying to help cure those pesky headaches or get your kids to fall asleep on time. If you’re wondering just how affordable oil diffusers can be, check the buyer’s guide to the best oil diffusers — you’ll be sure to find one that fits your budget!
