Pesticide Might Be The Cause Of Microcephaly, Not Zika Virus, New Study Says

Pesticide Might Be The Cause Of Microcephaly, Not Zika Virus, New Study Says

Especially now that the Zika virus has officially arrived in the United States (via Florida), pregnant women across the country are worried about the possible effects that contracting this mosquito-born virus might have on their unborn children.  Many health organizations like the Center for Disease Control (CDC) have concluded that the Zika virus is responsible for microcephaly (a condition where a baby is born with a smaller than normal head and can have long-term cognitive problems because of it). However, a new study raises some questions about these conclusions.

The New Study: does Zika Really Cause Microcephaly?

This new study was undertaken by the New England Complex Systems Institute (NECSI) and recently published in the prestigious New England Journal of Medicine. In it, researchers did a large study of 12,000 pregnant Columbian women who showed signs and symptoms of the Zika virus.  What is interesting about this study, though, it that none of these 12,000 women gave birth to babies with microcephaly.

At this time, there were four cases of microcephaly reported, but this would considered to be at the normal rate of this birth defect, which occurs in approximately 2 out of every 10,000 births even in unaffected populations.

The researchers estimate that, throughout Columbia, there are or have been around 60,000 pregnancies affected by the Zika virus, so the absence of microcephaly births raised the inevitable question: if the Zika virus is not causes microcephaly, then what is?

A New Culprit is Named

So if the Zika virus is not causing these birth defects, what is?

The NECSI believes that the real culprit might well be a pesticide called pyriproxyfen, which, ironically, is widely used in Brazil to help control the mosquito population. The chemical is used in areas which have been particularly affected by microcephaly — and it has been used in the public water supplies at unprecedented levels.

The researchers, in making their argument, pointed out the following facts:

  1. Pyriproxyfen works to control the mosquito population by interfering with the development of larvae — and might well interfere with the development of human babies.
  2. Its chemical structure is similar to a form of vitamin A known as a retinoid. The use of retinoids with women during pregnancy has been linked with a variety of serious birth defects, including microcephaly.
  3. Pyriproxyfen has been used in Brazil in the public water supply at unprecedented levels — and this usage happened just before the outbreak of microcephaly in this country.
  4. The fact that other countries who have suffered from Zika virus outbreaks have not suffered from large numbers of microcephaly is suspicious.

The Study in Context

This study should be looked at in context in order to really appreciate its importance. To begin with, the manufacturer of pyriproxyfen has denied any link between its pesticide and birth defects. However, this has been belied by a neurodevelopmental psychologist from the Harvard School of Public Health whose research found a link between this chemical and smaller skull size in laboratory animals.

In the meantime, the use of this pesticide remains widespread in Brazil despite worries that it might be causing these defects in unborn children. The good news is that some countries are exploring alternatives to mosquito control, that does not harm the human population in any way. This includes the use of larvae-eating fish and mosquito traps.

The long and short of it is that the Zika virus, while certainly a threat to public health, may not be the culprit behind the outbreak of microcephaly — and alternatives to the use of pyriproxyfen should be investigated in order to reduce the potential health risk to pregnant women and their developing babies.

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!
