You really have the ability to smell others' sick smells

After the research process, the scientists discovered dozens of diseases that caused the body or the body's body fluids to have a special smell. Diabetes can cause your urine to smell like rotten apples and typhoid that makes your body smell of toast. Worse, yellow fever causes your skin to smell like live meat shops. This is strange, but the scent is not always clear, but some scientists think that people can actually 'sniff' if standing near someone who is sick.

We can even smell who is suffering from cancer or brain damage to make an early diagnosis. Concerning this problem, Joy Milne - a Scottish woman who is quite famous for being able to pinpoint exactly who is Parkinson's disease just by smelling their shirt. At first, everyone will be surprised by this information, but according to experts, anyone who has a normal olfactory system can smell such "sickness" .

People are inherently good at detecting disease, according to Valerie Curtis, a public health researcher at London School of Hygiene & Tropical Medicine (UK), author of the book "Don't Look, Don." 'Touch, Don't Eat'. 'Signs of disease are some of the most disgusting things,' Curtis said, referring to mucus, vomit or pus. helping us stay away from things that we think will harm ourselves, so using the nose to identify illnesses is basically just an evolutionary process throughout the existence and development of human.

But why does the body odor of an infected person change? The problem lies in our bodies constantly releasing volatile substances into the air. They can come from breathing or even pores and ingredients can vary depending on your age, diet or a disease you have. Bacteria that live in the intestines and on our skin are responsible for making up the body odor, by turning the products of the metabolism into a certain odor.

Joy Milne (right) is someone who can correctly diagnose who has Parkinson's disease just by smelling sweat.

Basically, the main body is the 'factory' that produces scents and based on the 'superpowers' of women who can smell Parkinson's disease , scientists believe they can exploit this information. to make the diagnosis earlier.

Parkinson's is one of the diseases that is difficult to diagnose. Most when a person goes to the clinic because the body starts showing the first symptoms, at that time, they actually lose half of the amount of brain cells that produce dopamine. However, about 6 years before Joy Milne's husband was diagnosed with Parkinson's, she noticed that his body had a strange smell.

"Les's body smells like wood or musk," Milne said. In an experiment conducted many years later, in a room arranged in a series of Parkinson's patients, she realized that the scent did not seem to be unique to Les. All Parkinson's patients smell like that.

Knowing she had this strange ability, she later went to tell a researcher named Tilo Kunath of Edinburgh (the capital of Scotland), who discussed with his colleague - Perdita analytical chemist Barran. They have the same speculation that the smell that Mrs. Milne could smell is probably the only characteristic smell in older people. This conclusion seems to put an end to the hope for the birth of a new Parkinson diagnostic solution.

At the same time, a number of biochemists interested in the matter decided not to give up the analysis of Milne's strange ability. They invited her to perform a trial with shirts: smelling the sweat from the shirt of 6 people who were diagnosed with Parkinson's and 6 people who were not sick. Milne correctly identified where the coats of six Parkinson's patients were, and she confirmed that one of the people in the supposedly healthy group seemed to be sick. Eight months later, a person in the control group was diagnosed with Parkinson's.

Barran working at the Manchester Biotechnology Institute before the clue decided to use chemical measures to determine whether a characteristic odor of Parkinson's disease exists. She and her colleagues hope they can develop a way to identify Parkinson's smell if it really exists, a more accurate and realistic approach.

Star-nose mole is one of the most sensitive olfactory species on the planet.Not only does it use the tentacles on the nose to sense its prey, it can also smell underwater by constantly blowing out and inhaling the air bubbles.

First, the team is in the process of working to identify the chemical molecules involved. Among the thousands of volatile compounds ever known, many compounds have no details or if they exist, they exist only in the perfume industry. With funding from the Parkinson Foundation (UK) and Michael J. Fox Foundation, Ms. Barran's group collected more than 800 sebum samples, a skin-secreting slime on the volunteer's back.

Experiencing the first preliminary tests, they found some outstanding molecules in sebum of people with Parkinson's disease. The team of scientists then conducted analyzes to find out how these molecules formed the scent and acted as a warning sign, as soon as symptoms did not appear.

'Joy Milne has an extremely good sense of smell , ' Barran said, 'but she's not the only one who can smell it.' Many researchers have shown that the ability to sense the smell of the human olfactory system is better than what we can imagine. Based on the amount of olfactory neurons in the brain, scientists think humans can smell better than mice and that possibility is in the middle of the mammalian group.

Perhaps the biggest barrier to our sense of smell is the lack of attention to smell and we don't have a complex enough language to describe all the smells that can be smelled. Similarly, we may not pay attention to the change of body odor itself or loved ones when health problems. If you take a bit of care, scientists think we can actually detect the disease by smelling it.

In a study published in 2017 in the journal of the National Academy of Sciences, participants were able to determine whether a person was healthy or ill by smelling body odor and see pictures.
