Suicides in the US and Mexico increased because of the hotter weather

The findings of the new study are published in the July 23 issue of Nature Climate Change. According to Medical Daily, after analyzing medical data about more than 850,000 suicides in the US for 36 years and more than 611,000 suicides over the past 20 years in Mexico , researchers think climate change could lead to an increase in suicide rates across the United States and Mexico.

They estimate an average temperature rise of 1 degree C will cause suicide rates to rise 0.7% in the United States, 2.1% in Mexico, which means there will be an additional 21,000 suicides in 2050 in the two countries.

Medical Daily revealed, the team also examined the language used on social media. The proportion of certain words (such as " lonely", "stuck" or "suicide" ) is measured in more than half a billion tweets. They found "strong evidence that hotter weather increases both suicide rates and depressive language use on social networks ."

Solomon Hsiang, Professor at the University of California, Berkeley (USA), said that when reviewing documents on conflict and violence, people found that people fought more when the weather was hotter. " Heat profoundly affects people's minds and how we harm them," he remarked .

Marshall Burke, Associate Professor at Stanford University (USA), said: "Hotter temperatures are clearly not the single most important risk factor for people to commit suicide. But our findings suggest The idea that warming can have a big impact on the risk of suicide is important for our understanding of mental health as well as what we expect when the temperature continues. Warming'.

Page Medical Daily said, since the 1800s, the number of suicides has tended to be higher in the warm season like summer and spring. Texas, one of America's hottest states, has a higher suicide rate. And all these figures have increased, especially in recent times.

Some experts believe that sunlight increases serotonin levels, which can increase aggressive behavior in people diagnosed with depression. Similarly, another theory related to the effects of allergies and seasonal fire is also used to explain the phenomenon.

According to the US Centers for Disease Control and Prevention announced in June 2018, from 1999 to 2016, suicide rates in most states in the United States skyrocketed by more than 30%. Nearly 45,000 people committed suicide in 2016, making it one of the top 3 causes of increased death in the US, along with Alzheimer's disease and overdose.

The United Nations World Meteorological Organization in March showed that the past 3 years are the hottest record recorded. The World Health Organization reports heat stress related to climate change, which could cause an additional 38,000 deaths a year worldwide between 2030 and 2050. Reuters reported in May. This year, more than 60 people died in Karachi (Pakistan) when the temperature increased above 40 degrees C.
