Loss of appetite reduces desire

For humans, the sense of smell plays a very important role, but is often underestimated. The latest scientific research has revealed how olfactory can reflect and affect our health condition, such as losing the smell of the nose will reduce "suffering". sexual desire.

Colds can devastate the sense of smell

According to experts, when smelling a certain smell, what we actually discovered is that the scent molecules spread in the air from an object or object. These molecules enter the nose and are stuck in cilia, which is closely attached to the olfactory "sensory receptors" or nerve cells at the top of the nasal cavity. If there is enough aroma molecule to reach a cell, it fires a signal down the olfactory nerves that run from the nose to the brain, where the scent is identified.

As people age, people will experience serious degradation of their ability to smell everything. This process can be aggravated by colds and exposure to epithelial damage containing olfactory receptors. Therefore, people with colds are more likely to have a worse sense of smell later in life. Richard Doty, professor of ear and nose and throat specialist at the School of Medicine at the University of Pennsylvania (USA), reports that up to half of people aged 65-90 have lost their sense of smell. This can lead to a serious impact on taste, because 75% of what we feel about the taste is actually the scent. This is why we often prefer stronger flavors when we get older.

Women have a more sensitive sense of smell than men

Women tend to own a sense of smell more sensitive than men. There is a theory that this phenomenon is partly due to hormones. In fact, your sense of smell can be sharpest around the time of ovulation, when estrogen levels peak. According to Professor Doty, similar fluctuations in the olfactory cycle tend to occur in women taking daily contraceptives.

Pregnant women sometimes also report stronger sense of smell. This is thought to be related to evolution, helping women better choose what to eat to protect their babies.

One of the functions of the sense of smell is to warn us about danger , such as poison gas or fire. Even so, we can adapt to unpleasant odors over time. " Take Gorgonzola cheese as an example. The smell is very annoying and the kids hate it. That unpleasant smell is caused by bacteria, but it is really nontoxic and we will learn to overcome the impression. initial fear or aversion The process may take days, even years, depending on how often you interact with it, ' explains Professor Tim Jacob from Cardiff University (UK).

Loss of smell can be caused by diabetes

Odor loss originates from many different causes. In addition to age-related degradation, it may be the result of viral infections or a head injury, damaging the olfactory nerves.

Damage to the brain through stroke can also lose the nose's ability to smell. Research has shown that loss of smell can be one of the first symptoms of neurodegenerative diseases like Parkinson's and Alzheimer's, but patients often don't know it.

Diabetes can also contribute to loss of smell. The reason is, nerve damage is a known long-term complication of diabetes. The phenomenon occurs when small blood vessels provide nerve damage due to chronic high blood sugar.

Loss of smell is easy to reduce sexual desire

Researchers have discovered an important link between sex and smell. Some people with a sense of loss notice a significant decline in " sex " desire. According to Professor Jacob, this is because, sense of smell is a form of communication between couples. In fact, the sense of smell can help us choose partners or partners.

"We are fascinated by people with different immune genes - an evolutionary mechanism that encourages us to transmit different immune genes to our offspring. And our body odor is caused by these immune genes." " explained Jacob.
