People are losing their sense of smell because of pollution

The current habitat is destroying the sense of smell, making people crave more salty food and have a fatter appearance.

Unpleasant odors caused by pollution, garbage has not been collected, even a messy room . is eroding the ability of people to recognize the natural nuances of humans and make them weaken. - Dr. Kara Hoover, expert in olfactory evolution warns.

Today we are not interacting with the environment and living in a very polluted place - Dr Kara Hoover, Durham University said.

Speaking at a meeting of the Association for the Advancement of American Science in Boston, Dr. Kara Hoover said that people who are weak about odors will be more likely to be obese because they tend to seek consciousness. more salty, stronger smell, which is the cause of high obesity risk. They are also at high risk of mental health problems such as anxiety and depression.

On the contrary, those with a strong sense of smell will have lower body weight.

Humans' sense of smell has evolved in a very rich landscape, when we have regular exposure to the environment, the team at Durham University says, but now, we don't interact. with nature and living in a very polluted environment.

People who lose their sense of smell are often very worried about their own body odor, because they don't know whether they smell or not, Dr. Hoover added: "They worry about not being able to smell the dangerous smell like gas leak or smoke ".

Obesity and eating preferences change because of the sense of smell.

Poor quality of life and depression make us not feel much about the taste of food anymore. According to Dr. Hoover, this concern increases the risk of developing more serious mental health problems.

Last week, London Mayor Sadiq Khan threatened to ban old diesel cars because of high levels of air pollution. He received a series of alarms on air pollution in the capital, where pollution is related to about 9,000 deaths each year.

A new study this month also suggests that diesel pollution could double the risk of developing dementia. Also poor air quality is believed to be the cause of heart attack or stroke in humans.

Poorer people will be exposed to more pollution, with bus passengers about 8 times more likely to experience an impaired sense of smell than those who use a private car. People who live in contaminated areas or where garbage is not regularly collected are also more likely to be impaired.

Recently, Dr. Hoover conducted a study comparing the smelling ability of Homo sapiens with Neanderthals and Denisovans.

Car smoke is one of the things we breathe every day.

During the process, she discovered that Denisova, from Siberia, had "little function" of a sense of smell compared to modern humans and Neanderthals, meaning they could not smell the grass. Her research concluded that modern human consciousness is similar to that of Neanderthals.

During the Boston meeting, Dr. Hoover said, she wanted more "green" details of the city to protect people's consciousness of the smell.

However, this ambition is under threat, due to the increase in truckloads used in road traffic due to a cut of 4 million euros of subsidies for rail transport in Europe. In the UK alone, it is estimated that this reduction makes new trucks increase to 520 trucks per day.
