Have you ever felt your joints shake before a storm? Have you ever had a sudden migraine in a pre-winter period? Could there be a scent of cologne (famous perfume in Germany) that brings you back to some distant memory? Our bodies can do some strange things and seem to be unable to explain. On Womansday page, experts will decipher 9 of the hundreds of mysterious possibilities of the human body, especially some of the abilities that you yourself don't own.

1. The osteoarthritis pain can predict the weather

Robert Tail, a medical doctor from the Department of Orthopedic Surgery, said the story of joints creaked before a shower of rain was not just a word of mouth for old women.

He explained: 'When a storm is coming, air pressure drops. The sensory nerve fibers of the main joints increase the fluid pressure in the joint, resulting in an increased sense of pain ' . Frequent aches and pains seem to be very uncomfortable, but at least those who suffer from this mysterious joint pain know when to bring the umbrella to the street.

2. Eyes may warn when your body is too cold

Everyone is trembling when it is cold, but how can we know the temperature is falling to dangerous levels?

According to the vision specialist Dr. Rupe Hansra, Deputy Director of Ophthalmology at LensCrafters, eyes are windows that signal when the outdoor temperature drops too low. When the body temperature drops seriously, the blood vessels in the eye shrink to convert into energy. That may cause the temporary blindness that model Kate Upton encountered when taking photos for Sports Illustrated bath products in Antarctica. The temperature when she was there lowered to minus 129 degrees Celsius.

3. Your heart rate can be said in advance about the future

The heart does not know when you get married or how much money you get in the business profit statistics this month. However, a recent study shows that the heart can predict many events with certainty without any hint.

Researchers from Northwesten University (in Evanston, Illinois), University of California, and Padova University (Italy) have allowed researchers to view a series of images in an unpredictable order and monitor their reactions. Some pictures are neutral, others often feel excited.

When monitored, the scientists discovered the participants' heart rate increased by about 10 seconds before the excited picture was shown, indicating that the heart could feel it when something was palpable or worrying imminent. So advice for you: Listen to what your heart says.

4. A woman's vagina can catch a signal in front of the brain

You may think that the brain knows when the body is stimulated. But a new Dutch study gives another result.

Dr. Yvonne K. Fulbright, the Sexual Health Ambassador and Astroglide Relations, reported that the team has shown some pornographic films to women. With a properly placed electronic device that shows the woman's vagina with self-lubricating reflexes before they are aware of the state of their body being stimulated.

5. The pupils of the eyes reveal the situation you are in love with

If you want to hide your feelings for someone, stand where the light bulb dims when he is near. Dr Hansra said: 'When attracted to someone, the eye pupils tend to relax'. Sometimes, you have to thank the sympathetic nervous system, which controls pupil elasticity, for "telling your heart".

The mechanism does not only happen when you are attracted to someone. The study also notes that the pupils of your eyes are also enlarged when you look at anything that is voyeuristic, from a desert to a dazzling sunrise.

6. The sense of smell can bring you back to the past

Ever had a fragrant aroma immediately brought you back to the memories area far away? Maria Larsson, associate professor of psychology at Stockholm University, Sweden, describes our sense of smell as a 'magic time machine'.

The olfactory cortex, which functions to control people's sense of smell, resides in the border system, where emotions are generated and locks the emotional storage. The scent, memories and emotions are so deep that the fragrance of the deceased grandmother can shed tears.

7. Your eyes can predict the coming spring

Outdoor weather can be horrible, predictable allergy symptoms for warm days are hiding somewhere. Dr Hansra said: 'The amount of pollen and preschool increases before the weather changes, and your eyes recognize them first, the eyes will itch and watery'.

8. The digestive apparatus can give you a great power

A mother can lift a car if her child is stuck below. When your brain receives dangerous alarms from the sensory nervous system, the adrenaline hormone secretes, increases your heart rate, breathing, pupil relaxation and most importantly, the digestive tract stops working for The muscles are an extraordinary strength.

Usually, your digestive tract can't lend its other parts of its body permanently. However, when urgent, the ability to stop burning its energy is maximized to help you overcome danger. This explains why a person is in a dangerous state, they can perform actions that they have never and will never do the second time like that.

9. Migraine reflects severe temperature changes

Many people with migraines appear to be particularly sensitive to weather changes, such as temperatures that are too hot or too cold.

Medical doctor Jerry W.Swanson, a neurologist at the Mayo Clinic, Rochester, MN said: 'Weather changes can imbalance the chemicals in the brain, including serotonin and cause migraines. head ' . An evolutionary theory explains this situation as follows: headaches will make us find a safe place when adverse weather is coming. Through this study, Dr. Swanson advises people to stay indoors when it is too cold or too windy to avoid migraine.
