in addition to detecting 1 trillion different odors, the nose is also a mirror of human health, which can reflect a variety of health problems. Confirmed by scientific research, the nose can reveal six health secrets.

1. Nasal mucosa reflects sinusitis and nasal allergy

. Normal nasal mucosa should be pink. If the nasal mucosa is blue, white or swollen, you may suffer from allergic rhinitis or some nasal allergy that causes inflammation. A red nose usually indicates an infection. If accompanied by fever or nasal sensitivity, sinus bacterial infection may occur.

2. Whether intranasal bacteria reflect obesity

a new study found that there was a certain association between nasal and throat flora and body mass index (BMI). The greater the weight of the male, the more potential pathogenic bacteria in the nasal cavity. The slimmer and more attractive men had less bacteria in their nasal cavity. Therefore, the number of bacteria in the nasal cavity is closely related to whether the body is obese or not.

3. Nose shape may determine “partner potential”

a new study has found that a correct and attractive nose is a signal of physical health. Therefore, liking a correct nose bridge is not only a manifestation of people’s love for beauty, but also the result of “natural selection”. A new study found that when a person’s nose is more straight and centered after plastic surgery, his facial attraction will increase significantly.

4. Looking at the nose can diagnose schizophrenia

the study found that the nose is helpful to diagnose schizophrenia. Gene analysis of intranasal neuronal samples is helpful to diagnose schizophrenia. In addition, the nose can also help diagnose brain diseases such as Alzheimer’s disease. Many patients with this disease have olfactory loss before onset.

5. Rosacea is related to a variety of diseases

scientists say that red nose (rosacea) is not only related to drinking, but also related to a variety of diseases, such as stress or anxiety, allergies, hay fever or thyroid diseases.

6. The color of snot is a health sign.

the snot of healthy people is clear. In case of serious diseases, white blood cells secrete a green enzyme, which will lead to yellow or green snot. Nosebleeds may be associated with bleeding disorders or hypertension. However, in most cases, nosebleed is normal and harmless. Don’t worry too much.
