The first pillows we know of date back to Ancient Mesopotamia. They were made of stone, and only wealthy people could afford them. Unlike ancient stone pillows, the ones we use today are soft and fluffy, and many people can’t sleep without hugging a big cozy pillow. But in fact, sleeping with a pillow may not be the best way to rest, as it can affect your body and your mood.
We at Bright Side understand that it can be difficult to part with your favorite pillow, but sleeping without it has many health benefits, and we did our research to introduce you to some of them.
1. It prevents back pain.
Many pillows can lead to an unnatural sleeping position and the support they provide doesn’t last long. Although the pillow itself won’t cause your back to hurt, it can worsen many of the underlying symptoms. When you sleep without a pillow, your spine can rest and your body is in its natural position.
2. It helps you to deal with neck pain.
Most pillows can’t help you sleep in the right position, and can even make sleeping postures worse. Bending your neck in any way for a long time will make you uncomfortable, and pillows that are too firm or too soft may lead to neck pain.
3. It combats headaches.
If you’re waking up with a headache or feeling light-headed, your pillow might be to blame. Pillows that are too high cause your head and neck to round forward, and they add more tension to the neck muscles. This might give you a headache in the morning once you’ve gotten out of bed.
4. It may alleviate stress.
If your pillow makes you uncomfortable at night, you might end up tossing and turning in your sleep. The more sleep disturbances you have, the less time your body has for many important functions that occur during sleep. Constant sleep deprivation can affect your mood and thinking skills, and will cause your body to release more stress hormones during the day.
5. It prevents facial acne.
Your skin will thank you for getting rid of your pillow. Your face is normally pressed on your pillow for most of the time during the night. You probably don’t wash your pillowcase every day, and it collects dirt, oil, and household dust on it. All of this can lead to breakouts, inflammation, and premature wrinkles.
6. It may be good for your hair.
If you’re waking up in the morning with dry and tangled hair, you might want to forgo your pillow for the sake of your locks. When you’re tossing and turning at night, your hair is rubbing against your pillowcase, causing it to break. Pillowcases can also absorb the oils from your hair, leaving it dry and brittle.

Synaptic Information Storage Capacity Measured With Information Theory
Ever wondered just how much data your brain can hold? We often compare the brain to a supercomputer, but what if that comparison isn’t just a metaphor—it’s literal? Deep within your brain, at the junctions where neurons meet, lies an extraordinary form of biological storage: the synapse. And thanks to breakthroughs in information theory, we’re beginning to quantify its staggering capacity.
In this article, we’ll dive into how synaptic storage works, how scientists measure it, and why this knowledge could shape the future of data storage—from artificial intelligence to DNA-based memory.
What Are Synapses and Why Are They Important?
Think of neurons as the brain’s messengers. But without synapses—the gaps between them where signals are transmitted—those messages would go nowhere. A synapse is where the magic happens: it’s the space where one neuron sends a chemical or electrical signal to another, sparking thoughts, memories, movements, and more.
Now here’s the kicker: each of these tiny junctions doesn’t just pass along data—it stores it.
Your brain has about 86 billion neurons, and each one can form around 1,000 synapses. That’s a total of roughly 125 trillion synapses buzzing away in your brain, constantly sending and receiving signals. These connections form the foundation of your memories, knowledge, and perception.
Measuring Synaptic Storage with Information Theory
To understand how synapses store information, scientists turn to information theory—a branch of mathematics that deals with encoding, decoding, and compressing data. Think of it like analyzing how much a hard drive can hold, but on a biological scale.

Each synapse, as it turns out, can store up to 4.7 bits of information. That might not sound like much until you consider the scale:
- 1 bit is a single piece of binary data (a 0 or 1)
- 4.7 bits per synapse × 125 trillion synapses = over 500 trillion bits of potential storage
Translated into digital terms, your brain can theoretically store more data than the entire internet—all in a compact, low-energy package powered by biology.
The Brain’s Efficiency: Powering Trillions of Connections
Here’s something even more mind-blowing: while your laptop heats up and guzzles electricity, your brain handles all of this complex storage and processing using roughly 20 watts of power—that’s about the same as a dim light bulb.
This insane efficiency is what’s inspiring researchers to build neural networks and deep learning systems that mimic the brain. If computers could process and store data like synapses do, we’d have faster, smarter, and greener technology.
Artificial Intelligence and Synaptic Models
The field of AI, especially machine learning and deep learning, borrows heavily from how the brain processes and stores information. Artificial neural networks use layers of interconnected nodes (inspired by neurons) to simulate learning.
But here’s where it gets interesting: researchers are now using real data about synaptic information capacity to refine these systems. The goal? To build AI models that are more human-like, not just in intelligence but in efficiency and adaptability.
Imagine a future where your smartphone thinks and stores information with the same elegance as your brain. That future isn’t science fiction—it’s science.
Beyond the Brain: DNA as the Ultimate Storage Device
While the brain remains the pinnacle of biological storage, it’s not the only game in town. Enter DNA, nature’s original information vault.
DNA doesn’t just code for life—it can be used to store digital data. And we’re not talking small files here. A single gram of DNA can hold up to 215 petabytes of data. That’s 215 million gigabytes—enough to store every photo, song, and document you’ve ever owned, plus millions more.
In fact, researchers have already done it. In one groundbreaking study, scientists encoded a 52,000-word book into synthetic DNA. They converted the digital content into binary (0s and 1s), then translated those digits into DNA’s four-letter alphabet: A, T, G, and C. The result? A physical strand of DNA holding a complete, retrievable digital file.
Why DNA Storage Matters for the Future
Traditional storage devices—hard drives, SSDs, even cloud servers—have physical limits. They degrade over time and take up massive amounts of space. DNA, on the other hand, is incredibly compact, durable, and stable for thousands of years if stored properly.
If scaled correctly, DNA storage could revolutionize how we preserve knowledge. Imagine backing up the entire contents of the Library of Congress on something no bigger than a sugar cube. That’s the level we’re talking about.

Bridging Biology and Technology
What’s exciting is how these two areas—brain synapses and DNA storage—are starting to intersect. Both are nature’s proof that small-scale systems can handle mind-blowing amounts of data. As scientists continue to decode these systems using information theory, they’re finding ways to integrate them into technology.
It’s not about replacing computers with brains or turning DNA into a USB drive. It’s about learning from nature’s most efficient designs to build the next generation of computing and storage systems.
Conclusion: Reimagining Storage in a Biological World
Your brain’s 125 trillion synapses silently store and process more information than entire server farms, all while sipping on 20 watts of energy. Meanwhile, DNA—the code of life—is showing us how to pack massive libraries of data into microscopic strands.
By measuring synaptic storage capacity with information theory, we’re not just understanding the brain better—we’re laying the foundation for a new era of intelligent, efficient technology.
The takeaway? Nature has already solved problems we’re only beginning to understand. And the more we study it, the closer we get to unlocking the true potential of both our minds and our machines.
