10 Body Reactions That Most of Us Don’t Know About

Scientists still cannot find an explanation for some phenomena related to the human body, let alone ordinary people. We are not always clear about the reasons for even quite familiar processes that regularly occur within us.

We decided to delve into physiological phenomena and find out what causes them. And as a bonus, we offer you a mysterious story that puzzled even medicine can’t explain..

Sunburn

Have you ever noticed how sunburns take a few hours to form after you’ve been out in the sun? That’s because the apoptosis process takes a bit of time to occur. If you’ve accumulated too much UV damage, your skin becomes full of dead skin cells.
The best way to prevent sunburns is to keep your skin covered. Wide-brimmed hats, sunglasses, and long-sleeved shirts and pants are the best way to avoid sun damage. You can’t stay completely out of the sun 100% of the time, and that’s where sunscreen comes in.

Craving for junk food

Do not blame yourself for wanting to treat yourself to chips, sweets, or other mischief. Eating disorders are often triggered by mental health disorders such as depression and eating disorder treatment centers usually see the highest increase in admissions during the winter months and many treatment centers hold their therapy activities outside in order to have the highest amount of sunlight exposure as possible. The stress of the holidays, gloomy skies, lower levels of serotonin and vitamin D during the winter months are known triggers for seasonal affective disorder and also can increase the risk of eating disorders.

Gestures

Some physical actions are hardwired into our genes. A study observed that blind people raise their hands to depict the victory gesture after winning even though they have never witnessed it themselves.
Raising your arms to demonstrate the victory symbol comes naturally to all of us. Scientists believe that the desire to flash the victory gesture comes from within. They believe that it is hardwired into our genes. And, it’s not just the victory gesture. Psychologists believe that this applies to all gestures that suggest pride or shame.

Allergy

Allergies occur when your immune system reacts to a foreign substance — such as pollen, bee venom or pet dander — or a food that doesn’t cause a reaction in most people.

Your immune system produces substances known as antibodies. When you have allergies, your immune system makes antibodies that identify a particular allergen as harmful, even though it isn’t. When you come into contact with the allergen, your immune system’s reaction can inflame your skin, sinuses, airways or digestive system.

Shivering and goose bumps

Shivering is a bodily function in response to cold in warm-blooded animals. When the core body temperature drops, the shivering reflex is triggered to maintain homeostasis. Skeletal muscles begin to shake in small movements, creating warmth by expending energy. Shivering can also be a response to a fever, as a person may feel cold. During fever the hypothalamic set point for temperature is raised.

The nature of goose bumps is very diverse: they can appear both in response to pleasant sensations and fear. For example, the kitten in the photo above was covered with goose bumps from fear of heights. This is also an ancient instinctive way to fight fear: thanks to the raised coat, the animal seems larger and can more successfully scare away the enemy.

Weather sensitivity

Weather sensitivity is characterized by the reduction of the threshold of the autonomic nervous system. The affected person perceives physical reactions to climatic changes (heat, cold, wind, humidity) and thus feels tired, irritable, unfocused or depressed. Typical symptoms include headache, dizziness and sleep disturbances.


Women and the elderly are affected more frequently. The weather sensitivity is also promoted by a hectic lifestyle, unhealthy diet, stress or strong tension. Weather sensitivity leads to a reduced general condition, reduced performance and depressed mood.

Fighting stress with music

It turns out that you need to include your favorite playlists more often: it’s not only nice, but also useful. When we listen to music, our heart begins to beat it in time, this helps to lower blood pressure and improve cardiovascular activity. At the physiological level, this explains the fact that music helps us relax and calm down.

Sweating

For a person, sweating is primarily a means of thermoregulation: for example, in hot weather or during intense physical exertion, the brain sends a signal to cool the body so that the temperature does not exceed 37 degrees.

Sneezing

This phenomenon has a fairly simple explanation: when dust or other particles enter the nostrils, the nose reflexively throws air back to clear them. But there are cases when people sneeze when they go out into the bright light or when eating spicy food, and scientists still argue over the reasons for this.

Bonus: Hallucinations diagnosed

In 1984, a healthy woman went to the clinic because she began to hear voices urging her to scan her brain for a tumor. They told her that they had previously worked in a children’s hospital, which they advised to turn to (this hospital, shown in the photo above, exists now). The hallucination did not lie: the tumor really was, and the woman was safely operated on. After the operation, she last heard voices saying: “We are glad that we helped you, goodbye.” Doctors suggested that perhaps on a subconscious level, the woman understood that something was wrong with her, although she did not feel symptoms, and the voices became not only a reaction to the tumor, but also its creation, since they disappeared with her.

And what stories about inexplicable phenomena have you heard?
