7 UNREAL Facts About Human Body🤯| Only 0.1% Know this Secret | Prashant Kirad

Summary

In this engaging science video, the presenter, Prashant, shares seven fascinating facts about the human body, backed by scientific explanations. From how your height slightly increases in the morning to the powerful role of the little finger, these intriguing insights highlight the wonders of our anatomy. The video explores how music affects heartbeats, the brain's energy potential, the surprising similarity between human DNA and bananas, the protective power of stomach acids, and even the invisible glow of your skin based on emotions. It's a fun and informative exploration of the incredible functions of the human body.

Takeaways

• 😀 Your height is slightly taller in the morning due to spinal fluid compression, and you lose about 1 cm as you go through the day.
• 😀 The little finger contributes 50% of your hand’s strength, and losing it reduces your hand's power significantly.
• 😀 Your heart rate responds to the type of music you listen to—upbeat music makes your heart pump faster, while slow music slows it down.
• 😀 Your brain generates enough energy to power a 15-watt light bulb, thanks to the electrical signals transferred by neurons.
• 😀 Humans share about 50% of their DNA with bananas, demonstrating a common ancestry between all living organisms on Earth.
• 😀 Hydrochloric acid in your stomach is so strong it can dissolve metals and plastics, but your stomach lining protects you from it.
• 😀 Your skin can glow in different colors, but it’s usually invisible to the naked eye—this change happens due to hormones like adrenaline and oxytocin.
• 😀 Gravity compresses the fluid in your spine during the day, which is why your height is reduced in the afternoon and returns at night.
• 😀 In Japan, there’s an ancient custom of cutting off the little finger as a punishment for betrayal, as it’s believed to drastically weaken the hand’s power.
• 😀 Music has a direct impact on your heart rate and emotions—fast-paced music can make you feel more energetic, while slow music can have a calming effect.

Q & A

Why is it possible for your height to be slightly taller in the morning?

Your height changes throughout the day due to the compression of spinal fluid caused by gravity. In the morning, after a night of rest, gravity's effect on your spine is reduced, allowing the fluid between the vertebrae to expand, making you slightly taller. This fluctuation can be up to 1 cm.

Why is the little finger so important for hand strength?

The little finger contributes nearly 50% of the strength of your hand. Its unique position and structure help in gripping and holding objects. Losing the pinky drastically reduces hand strength, as it plays a crucial role in coordination with the thumb.

How does music affect your heart rate?

Music influences your heart rate through a process called entrainment. The rhythm of the music you listen to synchronizes with your heartbeat. Fast-paced music increases the heart rate, while slow, melancholic music causes it to slow down.

What is the connection between the energy in your brain and its ability to power a light bulb?

The brain produces electrical energy through the activity of neurons. This energy is enough to power a small 15-watt lightbulb, as the chemical energy used by neurons to send signals can be harnessed in a measurable form.

How similar is human DNA to that of a banana?

Human DNA is about 50% identical to that of a banana. This similarity stems from the fact that all living organisms, including humans and bananas, evolved from a common ancestor, sharing fundamental biological building blocks.

Why doesn't the strong acid in our stomach harm the stomach lining?

The stomach produces hydrochloric acid to help break down food and kill harmful bacteria. However, the stomach lining is protected by a mucus layer that prevents the acid from damaging the stomach tissue.

How does the stomach acid help protect the body from infections?

Stomach acid, specifically hydrochloric acid, helps destroy harmful bacteria and viruses that enter the body with food. Without this acid, the body would be more vulnerable to infections from harmful microorganisms.

Can emotions really cause physical changes in skin color?

Yes, emotions like anger or love can cause subtle changes in skin color. The release of hormones like oxytocin and adrenaline can alter the color of the skin, though the changes are not always visible to the naked eye.

What scientific principle explains the ability of music to affect heartbeats?

The scientific principle behind this is called entrainment, where external rhythms (like music) synchronize with biological rhythms, such as heartbeats. This explains how the tempo of music can cause the heart to beat faster or slower.

How do the structural changes in the body impact the strength of the hand?

The structural design of the hand, particularly the thumb and little finger, is key to hand strength. These fingers work together to provide the most power for gripping and lifting objects. Any loss or injury to these fingers can significantly reduce hand function.
