Surprising But Normal: Weird Body Reactions Explained

With the development of society, diversity and inclusiveness have become the mainstream trend. A variety of different talents come together to form the true face of society. Some people have peculiar physiological reactions, and there is even a group of people who experience similar situations. In fact, these reactions are normal. Let's take a look at which peculiar physiological reactions are normal.

Which peculiar physiological reactions are normal?

1. Going to the bathroom before bed

A significant number of people have a habit before bed: they must go to the bathroom, even if they don't feel the need, especially to urinate. Otherwise, they won't sleep well throughout the night. This physiological reaction is actually normal because it is a deeply ingrained habit or conditioned reflex. Many parents, in order to ensure their children sleep better at night, encourage them to go to the bathroom before bed. Over time, this conditioned reflex is formed. Some people, fearing frequent nighttime urination might disrupt their sleep, also go to the bathroom beforehand. This, too, becomes a habit over time. Therefore, this is normal and doesn't require excessive concern.

2. Staring at a word for too long and not recognizing it

Another physiological reaction we often encounter in daily life is when reading books or electronic devices, you might stare at a word for too long, and the next time you see it, you don't recognize it. This phenomenon is also normal and is known as semantic satiation. Prolonged fixation on a word can lead to a weakening of the individual's perception of that word. It is a psychological phenomenon, and since it is normal and doesn't last long, it doesn't have a significant impact on life. Therefore, there's no need to worry about it.

3. The sound of nails scratching glass causing discomfort

When it comes to the most annoying sounds, besides the words spoken by people you dislike, the sound of nails scratching a blackboard or metal sheet is something that universally resonates—a refusal that comes from the depths of the soul. Why do people hate the sound of nails scratching glass? Research shows that when people hear this sound, the auditory cortex of the brain interacts in a way that triggers a series of emotions such as fear, anxiety, and anger. Additionally, the range of sounds humans can perceive is from 20 Hz to 20,000 Hz, and the frequency range between 2,000 Hz and 5,000 Hz is considered the kind of noise that can drive people crazy. The sound of nails scratching glass falls precisely within this frequency range, so feeling discomfort upon hearing such a sound is a normal physiological reaction.

Besides these three, there are many other seemingly peculiar physiological reactions that are actually normal. This illustrates the importance of not imposing one's own likes and dislikes on others. What you consider peculiar may actually be normal, so it's important to learn to be inclusive and understanding.
