Think you know a lot about your body? Think again. Do you know why your breath smells in the morning? Or why your stomach growls when you’re hungry?
The Human Body is a manifestation of many sophisticated and intricate network of systems working together. Oftentimes, we take our reflexes for granted and we never question the reason. More accurately, we never bother finding out why. For example, the simple act of breathing requires multiple bodily systems functioning simultaneously. Another obvious reflex is removing your hand when it is scalded by boiling water.
So today, we will explain to you 4 interesting phenomenon you’ve experienced but have no idea WHY it happens and hopefully, shed some light on the living enigma which is your body. (Don’t worry, you don’t need to be a doctor to understand this article)
1) Stinky Breath In The Morning
Rise and Shine! But not with that breath! Don’t worry; you are not the only person with bad breath in the morning. In fact, it is common occurrence for many.
Foul morning breath results from bacterial related activities occurring in your mouth before you sleep. When you enter dreamland, your breathing slows and you don’t drink water; your mouth gets dryer and the oxygen level decreases. This is the ideal bacteria breeding ground and it starts feeding on the left-overs in your mouth. While doing so, they produce a gas (Sulphur) that causes your breath to stink!
You tend to shiver when you are really cold. Perhaps not so much in Singapore, but you’ll definitely experience when you visit the winter countries.
So..why does it happen?
In cold conditions, your body undergoes rapid heat loss and shivering is your body’s response. When you shiver, your muscles undergo rapid contraction and relaxation which produces heat in your body. This way, it’ll help you to fight the chilly environment by reducing heat loss and raising your core temperature. However, don’t just depend on it to combat the cold; shivering serves as a signal for you to put on extra clothing or turn up the thermostat.
“The average person blinks some 15-20 times per minute—so frequently that our eyes are closed for roughly 10% of our waking hours overall.”1 Blinking seems like a very simple, benign and seemingly useless action, however, it plays a crucial role in protecting our eyes.
The reason we blink is to prevent our eyes from drying out. Blinking spreads the moisture evenly throughout the eyes, keeping them healthy and moist.
Metaphorically, blinking is like an irrigation system. Just like how farmers use it to make sure that their crops are well supplied with water when the weather is dry.
4) Growling Stomach
Your stomach just had to growl while your were in the library or taking an exam. Most of us would definitely have experienced this “awkward moment” before. There are two explanations for this.
Murphy’s Law: Anything that can go wrong, will go wrong. Just accept it.
Scientifically, your stomach can growl any time. When your tummy is empty, the stomach sends message to the brain to signal for some actions to be taken. In response, your brain will instruct the gullet to push down any remnants of food into the empty stomach. After which, it’ll vibrate, prompting you to ingest something. It is this vibration of an empty stomach that generates the loud noises which cause us so much embarrassment.
