Life is full of mysteries although fortunately there is an explanation for almost everything. Furthermore, behind all the aspects that seem illogical there is always a scientific basis. With this in mind, a group of doctors focused on investigating why some of the rarest reactions of the human body.
Absolutely all of us have experienced the feeling of cold and immediately started to shiver. Also slight twinges in the body when doing intense exercise and other sensations that are impossible to avoid. Although behind each one there is always an explanation.
The origin of the strangest reactions of the human body
Regarding this topic, a team of specialists from Mayo Clinic explained the origin of some pretty strange and unusual but real things. The following is the answer to some of the most frequently asked questions.
Why do fingers wrinkle in water?
Initially it was thought that fingers wrinkled in water due to changes in fluids that occur between the tissues and the liquid in which they are immersed. Evolution experts found evidence that this may have allowed humans to better grasp objects in wet settings.
Something curious is that people with nerve injuries in their fingers or toes generally do not wrinkle their fingers in the same way.
Why do you sometimes feel a pulse in your ears?
The pulse in the ears can be due to various reasons. Tinnitus is usually described as a ringing in the ears but there is a variation in which the person feels and hears the pulse in the ears. This is called pulsatile tinnitus.
An increase in blood pressure or a blockage in the ear canal can cause a person to hear a pulse. Another cause may be an abnormality in the arteries near the ears. This is a reason to consult with your healthcare team.
Why do we shiver when it’s cold?
Shivering when it’s cold is a way of making your muscles shiver to generate heat. The body always tries to keep the temperature as close to 98.6 degrees (37°C) as possible.
Why do some people sneeze when they look at the sun?
This is known as the photic sneeze reflex. The theoretical explanation behind this reaction is as follows: the optic nerve, which detects a change in light, is located near the trigeminal nerve, which controls sneezing. A typical sneeze is caused by irritation in the nose, which activates the trigeminal nerve and triggers a sneeze.
When leaving a dark room into a brightly lit place, the pupils constrict. This rapid reflex begins in the optic nerve and can give the sensation of irritation in the nose, which causes sneezing. Not all people have this reaction, and it is not clear why some people do and others do not.
Why do I feel a twinge in my side when running?
Stitches in the side are caused by irritation of the diaphragm, a muscle that separates the lung cavity and the abdominal cavity. New runners or those increasing their pace or distance are more likely to feel twinges in their side.
Sometimes the cause is breathing too quickly or eating inappropriately before running. If you feel a twinge in your side, slow down, stretch your core muscles, and focus on breathing slowly and regularly.
Why does the eyelid suddenly start to twitch?
Tightening of the eyelid is called blepharospasm. The exact cause is unknown but is usually attributed to fatigue, caffeine consumption and stress. It is recommended to stretch the contracting muscle by gently pulling it with your fingertips in the area and rest well.
Generally, the contraction goes away on its own. If the contraction lasts more than a couple of days or you have difficulty opening your eyelid, you will need to be seen by a healthcare professional.
