The negative effects of global warming on the environment have been well-studied and documented in the past few years, but more studies are emerging proving that it also has negative effects on health, especially the brain and heart.


According to a consolidated report from the Climate and Health Assessment on the impact of climate change to health, extremely high temperature beyond the normal threshold has some bad effects to the health. The report outlines eight individual researches that examine the effects of climate change on the human body.

In a nutshell, the eight separate studies conducted by different research organizations and universities all over the world have one thing in common: climate change poses serious threats to human health not only here in the U.S. but across the world.

One of the findings of the studies is the negative effect of climate change to the heart and brain. It found that climate change increases the risk of serious mental health conditions such as post-traumatic stress disorder (PTSD), depression, and anxiety disorder.

Biologically, the three conditions result to imbalance of brain chemicals in the body called neurotransmitters. The neurotransmitters facilitate the effective and efficient communications between networks of brain cells called neurons. Abnormal levels of brain chemicals will result to different mental disorders.

Aside from various mental disorders linked to climate change, deaths due to heat waves are probably the most common and direct result of climate change, Reuters reported. In the same report, it was revealed that between 670 and 1,300 Americans die each year due to heat waves. The number is expected to hit the 27,000 mark by 2100, it added.

“I don’t know that we’ve seen something like this before, where we have a force that has such a multitude of effects. There’s not one single source that we can target with climate change, there are multiple paths that we have to address,” said Surgeon General Vivek Murthy, as quoted by Reuters while addressing the media at the White House on Monday.
