Does Air Pollution Increase Depression and Suicide?
Now, the first review of studies linking air pollution and mental health problems has found that exposure to air pollution increases the risk of depression and suicide.
"We already know that air pollution is bad for people's health, with numerous physical health risks ranging from heart and lung disease to stroke and a higher risk of dementia," lead author Dr. Isobel Braithwaite of University College London (UCL) said in a press release. "Here, we're showing that air pollution could be causing substantial harm to our mental health as well, making the case for cleaning up the air we breathe even more urgent."

The review, published in Environmental Health Perspectives Wednesday, looked at data from 16 different countries gathered between 1974 and September of 2017. The researchers found 25 studies that met their criteria and used them to assess the association between particulate matter exposure and depression, suicide, anxiety, bipolar disorder and psychosis. The strongest links were between exposure and depression and suicide, New Scientist explained. They found a limited association with anxiety and none with bipolar disorder or psychosis.
A person who spends six months in an area with twice the World Health Organization's (WHO) fine particulate matter (PM2.5) limit of 10 micrograms per cubic metre of air (μg/m3) would have a 10 percent greater chance of developing depression than someone living in a place that met the limit, the study found.
This means that reducing air pollution to the EU's legal limit of 25µg/m3 could substantially reduce depression around the world, Braithwaite told The Guardian.
"You could prevent about 15% of depression, assuming there is a causal relationship. It would be a very large impact, because depression is a very common disease and is increasing," she said.
The researchers also found that a short term increase in coarse particulate matter (PM10) exposure could increase suicide risk. If PM10 levels rose by 10µg/m3 for three days, suicide risk went up by 2 percent, the press release explained. The researchers ruled out other potential causes of risk, such as weather or the day of the week.
"This is something everyone is exposed to, so at the population level it is potentially concerning," Braithwaite told The Guardian.
Correlation or Causation?
Researchers are still not sure if air pollution actually causes mental health problems, or if it is merely associated with them. There is evidence that a physical mechanism could be in play.
"We know that the finest particulates from dirty air can reach the brain via both the bloodstream and the nose, and air pollution has been implicated in increased neuroinflammation, damage to nerve cells and to changes in stress hormone production, which have been linked to poor mental health," Braithwaite said in the press release.
The studies included in the review also ruled out many other factors that could influence mental health, such as income, education, employment and other health factors like smoking and obesity, The Guardian explained. The results also covered a wide variety of locations.
"This is a comprehensive review over a 40-year period," Ioannis Bakolis of King's College London, who was not involved in the research, told The Guardian. "Although the studies included were from different parts of the world – e.g. China, the U.S., Germany – and varied in sample size, study design and measures of depression, the reported associations were very similar."
However, the studies could not rule out the influence of noise or access to green space, New Scientist pointed out.
But senior study author Dr. Joseph Hayes of UCL pointed out that tackling air pollution would improve mental health even if it is not the direct cause of depression or suicide risk.
"A lot of what we can do to reduce air pollution can also benefit our mental health in other ways, such as enabling people to cycle or walk rather than drive, and enhancing access to parks, so this adds support to the promotion of active travel and urban green spaces," he said in the press release.

The ghoulishly named ogre-faced spider can "hear" with its legs and use that ability to catch insects flying behind it, the study published in Current Biology Thursday concluded.
"Spiders are sensitive to airborne sound," Cornell professor emeritus Dr. Charles Walcott, who was not involved with the study, told the Cornell Chronicle. "That's the big message really."
The net-casting, ogre-faced spider (Deinopis spinosa) has a unique hunting strategy, as study coauthor Cornell University postdoctoral researcher Jay Stafstrom explained in a video.
They hunt only at night using a special kind of web: an A-shaped frame made from non-sticky silk that supports a fuzzy rectangle that they hold with their front forelegs and use to trap prey.
They do this in two ways. In a maneuver called a "forward strike," they pounce down on prey moving beneath them on the ground. This is enabled by their large eyes — the biggest of any spider. These eyes give them 2,000 times the night vision that we have, Science explained.
But the spiders can also perform a move called the "backward strike," Stafstrom explained, in which they reach their legs behind them and catch insects flying through the air.
"So here comes a flying bug and somehow the spider gets information on the sound direction and its distance. The spiders time the 200-millisecond leap if the fly is within its capture zone – much like an over-the-shoulder catch. The spider gets its prey. They're accurate," coauthor Ronald Hoy, the D & D Joslovitz Merksamer Professor in the Department of Neurobiology and Behavior in the College of Arts and Sciences, told the Cornell Chronicle.
What the researchers wanted to understand was how the spiders could tell what was moving behind them when they have no ears.
It isn't a question of peripheral vision. In a 2016 study, the same team blindfolded the spiders and sent them out to hunt, Science explained. This prevented the spiders from making their forward strikes, but they were still able to catch prey using the backwards strike. The researchers thought the spiders were "hearing" their prey with the sensors on the tips of their legs. All spiders have these sensors, but scientists had previously thought they were only able to detect vibrations through surfaces, not sounds in the air.
To test how well the ogre-faced spiders could actually hear, the researchers conducted a two-part experiment.
First, they inserted electrodes into removed spider legs and into the brains of intact spiders. They put the spiders and the legs into a vibration-proof booth and played sounds from two meters (approximately 6.5 feet) away. The spiders and the legs responded to sounds from 100 hertz to 10,000 hertz.
Next, they played the five sounds that had triggered the biggest response to 25 spiders in the wild and 51 spiders in the lab. More than half the spiders did the "backward strike" move when they heard sounds that have a lower frequency similar to insect wing beats. When the higher frequency sounds were played, the spiders did not move. This suggests the higher frequencies may mimic the sounds of predators like birds.
University of Cincinnati spider behavioral ecologist George Uetz told Science that the results were a "surprise" that indicated science has much to learn about spiders as a whole. Because all spiders have these receptors on their legs, it is possible that all spiders can hear. This theory was first put forward by Walcott 60 years ago, but was dismissed at the time, according to the Cornell Chronicle. But studies of other spiders have turned up further evidence since. A 2016 study found that a kind of jumping spider can pick up sonic vibrations in the air.
"We don't know diddly about spiders," Uetz told Science. "They are much more complex than people ever thought they were."
Learning more provides scientists with an opportunity to study their sensory abilities in order to improve technology like bio-sensors, directional microphones and visual processing algorithms, Stafstrom told CNN.
"The point is any understudied, underappreciated group has fascinating lives, even a yucky spider, and we can learn something from it," he told CNN.

Your liver has a significant impact on your oral health, and that's where milk thistle works. The natural ingredient eliminates toxins from the liver and detoxifies your mouth as well.
Here is a study that proves how milk thistle is beneficial in detoxifying the liver.
The decaying of teeth is the initial phase of damage caused by bacteria thriving inside your mouth. Alfalfa works by reducing tooth sensitivity drastically and repairs the tooth decay caused by the bacteria.
It even stops the bacteria from growing further so you can expect good oral health.
A lot of natural supplements for teeth contain ginger because of its benefits on the teeth and the stomach. This ingredient present in the Steel Bite Pro reduces nausea and inflammation.
As per this study, there are umpteen other benefits of ginger as well, such as it maintains the pH inside your mouth.
Jujube seeds are good for boosting the immunity. Also, the ingredient has excellent antioxidant properties and is rich in Vitamin C, which is beneficial for the teeth and overall oral health.
Dandelion is a natural ingredient extracted from herbs. The ingredient is rich in minerals and has immense benefits such as fighting the bacteria and preventing the infections occurring inside your mouth.
Zinc is essential for teeth, and that is why many toothpaste brands advertise that their product contains a good amount of zinc. Further, zinc is a natural immunity booster and fights against bacteria to prevent gum disease and cavities.
Moreover, zinc repairs the enamel on your teeth that's damaged due to toothpaste or any other reasons. Here is a study that shows the benefits of zinc for your teeth and mouth.
Chicory root acts as a catalyst and increases the effectiveness of other ingredients. The reason why you get instant relief from pain after using Steel Bite Pro is due to the presence of chicory root in the pills.
Bacteria result in bad odor and can create cavities in the teeth. Furthermore, some bacteria result in tooth decay and harm the gums. The celery seeds fight these bacteria and prevent further growth.
To stay healthy, the teeth need to absorb the minerals present in the saliva. When your teeth are damaged for any reason, they stop absorbing the minerals, and the damage continues further.
Yellow dock helps the teeth to absorb the minerals while reducing the inflammation. Various studies have proven the efficacy of yellow dock for teeth and gums, and it is a natural and effective ingredient to keep the teeth healthy.
Raspberry, Chanca Piedra, and Artichoke
These three natural ingredients have similar properties and contribute a lot to the effectiveness of Steel Bite Pro. The ingredients have good amounts of vitamins and minerals, including Vitamin K, Vitamin C, magnesium, phosphorus, and folate.
The purifying agents will remove bacteria and other impurities from the mouth so that the other ingredients work well by repairing the teeth and gums.
The worst thing about oral issues is the pain that you have to go through. Steel Bite Pro claims to help with the pain as it contains feverfew, which is a natural pain reliever. The ingredient suppresses oral and dental pain so you will feel better instantly.
As per a study, there are some other benefits of feverfew, because it is a medicinal plant that suppresses other pains as well. Also, there are no side effects of feverfew at all.
The root of the burdock plant comes loaded with antioxidants that improve the gum health and the overall health of your mouth.
