Sleeping In 2 Shifts Did Humans Historically Rest This Way What Changed Video

For thousands of years, people across the world followed a two-shift pattern.
It is said that humans need seven to eight hours of sound sleep to stay healthy and active. But centuries ago, the idea of sleeping through the night in one go didn't really exist. People followed a very different sleep cycle that split the night into two parts.
Recently, an Instagram post by History Season shed light on this old practice. It explained how our ancestors lived with it and what finally led to its decline.
Sleeping In Two Shifts
'Humans used to sleep in a totally different way than we do now. But why did it change?" the post asked.
For thousands of years, people across the world followed a two-shift pattern, as per the post. They went to bed soon after sunset, usually around 9 PM and slept for three to four hours. Around midnight, they naturally woke up and stayed active for an hour or two.
During this time, people did various things like feeding animals, reading, praying, sewing, or even just chatting in bed. While doing these tasks, they used to rely on the light of the moon or oil lamps. Once done, they went back to sleep until dawn. This cycle, often called 'first sleep" and 'second sleep," was considered completely normal.
'Nights were no longer dark, so people started staying up later. However, they still had to wake up early for work," the post continued.
At the same time, society's attitude toward sleep changed. Continuous rest became the standard, while waking up in the middle of the night was seen as 'lazy and self-indulgent." By the 20th century, the concept of two-part sleep had almost disappeared.
What History Says
According to Science Alert, anthropologists found strong evidence that this bi-modal sleep was once the norm, especially in preindustrial Europe.
Historian A. Roger Ekirch, in his book At Day's Close: Night in Times Past, described how households slept in two stages. They would retire a couple of hours after dusk, wake in the middle of the night for one to two hours and then return to sleep until sunrise.
Ekirch found that references to 'first" and 'second" sleep started fading in the late 17th century. The change first appeared in Europe's upper classes and spread over the next 200 years.
Split Sleep In the Modern World
Most people today don't have the freedom to follow a split sleep pattern. With daily routines and work schedules, we usually try to get all our rest at night. Experts generally recommend about seven to nine hours of continuous sleep to feel well-rested.
For some, a divided sleep schedule may feel more natural. If the timing is right, it can provide 'two periods of increased activity, creativity, and alertness across the day."
Short naps are also known to boost memory, learning, alertness and mood. Some researchers even believe that sleep issues such as insomnia may be linked to the body's 'natural preference for split sleep."

Scientists Detect 'Cosmic Whisper' That Could Finally Reveal Dark Matter Secrets

When researchers combined data from multiple galaxy clusters, a faint step-like pattern emerged, called a 'cosmic whisper', a subtle hint that may signal axions' presence Dark matter, an invisible substance that makes up a significant portion of the universe, continues to perplex scientists. Although it cannot be observed directly, its gravitational effects shape galaxies and the cosmic web. Now, researchers may have discovered a promising method to study this elusive matter, bringing humanity closer to understanding the universe's hidden mass. The journey begins with a hypothetical particle known as the 'Axion'. Proposed in the 1970s, axions are extremely light and difficult to detect. Scientists believe these particles could make up a large fraction of dark matter. To date, numerous experiments on Earth, including CERN's ADMX and CAST projects, have tried to detect axions by looking into space, but none have produced definitive evidence. Galaxy clusters have now emerged as a promising avenue. These enormous structures, each potentially a quadrillion times more massive than the Sun, contain strong magnetic fields. Gamma rays emitted from supermassive black holes in distant galaxies can interact with these fields, potentially converting into axions. Professor Oleg Rukhaysky of the University of Copenhagen, Denmark, explains: 'Galaxy clusters act like a prism. As gamma rays pass through them, some may turn into axions, creating subtle patterns in the data." When researchers combined observations from multiple clusters, a faint 'step-like pattern' appeared, which they have termed a 'cosmic whisper', a subtle signal that could indicate the presence of axions. While this is not yet definitive proof, it narrows down where axions might exist and guides future searches. Scientists emphasise that this method can be repeated to gradually unravel the mystery of dark matter. This approach opens a new frontier in understanding the universe's hidden mass, bringing researchers one step closer to solving one of modern physics' most perplexing puzzles. view comments Disclaimer: Comments reflect users' views, not News18's.

Not A Comet, Harvard Scientist Claims Spooky Space Object Is Alien Spaceship

Last Updated: He said images from the Hubble Space Telescope show a glow in front of the object, but no tail behind it. Usually, comets display a bright tail of dust and gas pointing away. Harvard astrophysicist Avi Loeb has once again ignited a debate with his latest claim about interstellar object 3I/ATLAS. The object is currently hurtling toward the inner solar system. Most astronomers agree it is a comet. But Loeb believes it is an alien spaceship sent by an advanced civilisation. This is only the third known interstellar object to pass through our solar system. Loeb says its presence could be more than chance. He argues that it may even be a kind of test set by extraterrestrials. A 'Turing Test" for Humanity In a new blog post, Loeb compared the object to a Turing Test. He wrote that aliens might be judging human intelligence by how we respond to such a mystery. If scientists dismiss it as just a space rock, he says, aliens could see that as proof that humans do not deserve a 'high status" among civilisations in the Milky Way. Loeb pointed to Oxford astronomer Chris Lintott, who had called his idea 'nonsense on stilts." According to Loeb, an alien civilisation would likely see such dismissal as a failure of imagination and understanding. Most astronomers argue that the dust is evaporating from the Sun-facing side of the object. But Loeb disagrees. He claims the object is creating its light. He even suggested it could be a spacecraft powered by nuclear energy. The dust in front of it, he wrote, might be dirt that gathered during its long journey through interstellar space. Experts Remain Sceptical So far, almost every other expert has dismissed Loeb's claim. To them, 3I/ATLAS is just another comet. But Loeb insists that scientists are overlooking key details. The debate highlights a wider question about science and imagination. Should unusual space objects always be explained as natural, or should the possibility of alien technology be considered? For now, 3I/ATLAS remains a mystery in the sky. view comments First Published: Disclaimer: Comments reflect users' views, not News18's. Please keep discussions respectful and constructive.
