“I understand concepts, I comprehend things, I have memories, but they aren’t supported by any images,” Wathen said. Paul BokslagDutch-born artist Geraldine van Heemstra is at the opposite end of this unique way of processing. In reaction to cruel teasing from her brothers and school friends, van Heemstra learned to hide her sensory abilities as a child. “It was quite tricky at school as well, such as with math, where I would see the numbers in color,” van Heemstra said. “It was so frustrating at school because I would explain something, and then I would be laughed at,” van Heemstra said.

☆ Waking up in the middle of the night? Here’s why it could be normal
▼ + stars: | 2024-03-12 | by ( Taylor Nicioli | ) edition.cnn.com time to read: +7 min

Waking up several times throughout the night is a natural occurrence often due to sleep architecture, which are the stages of sleep that one cycles through every night. When people naturally wake up in the night, they are more likely to remember it happening during the second half of the night. That’s when people typically have longer REM stage, light sleep, while the first half of the night has longer stages of deep sleep instead. The most important thing to do when waking up in the middle of the night is to resist looking at the clock, Peters-Mathews said. It’s also important to ensure the awakenings are not happening from something external, such as disturbances from your sleep partner, Peters-Mathews said.

☆ ‘Sleepy girl mocktail’: Can it actually help you fall sleep?

Enter the sleepy girl mocktail. There are many things to consider before you add in — or rule out — a sleepy girl mocktail, he said. Setting a routinePart of what may make the sleepy girl mocktail helpful isn’t what’s in it as much as the routine of making and drinking it. Mocktails not cocktailsThe sleepy girl mocktail could help by kicking out the evening cocktail (or other alcoholic drink), said Dr. Marie-Pierre St-Onge, an associate professor of nutritional medicine at Columbia University. Maybe the sleepy girl mocktail works for you or maybe it doesn’t, but either way it’s crucial to establish your own version of a good night.

☆ How to tell when a migraine attack is coming

The study team found that sleep quality and energy were important indicators of a migraine attack on the following day. Migraine preventionKnowing when a migraine is coming can make all the difference — especially with growing interest in treating one before it starts, Tepper said. A migraine attack isn’t just a headache. It makes sense that people might be conservative about using medication for migraine pain, Tepper said. “There’s no downside because rimegepant has almost no side effects and is not associated with transformation into chronic migraine,” Tepper said.

☆ Chinstrap penguins survive on more than 10,000 naps a day, study finds
▼ + stars: | 2023-12-01 | by ( Amarachi Orie | ) edition.cnn.com time to read: +7 min

CNN —The art of nodding off appears to have been mastered by breeding chinstrap penguins, who take more than 10,000 naps a day, with each nap lasting an average of four seconds, according to a new study. They observed that the penguins in the colony engaged in more than 600 bouts of microsleep an hour. A 1986 study found captive, nonbreeding emperor penguins to have fragmented sleep called “drowsiness,” which also resembles the microsleep pattern of the breeding chinstrap penguins. He added that through these short bursts of sleep the penguins could “sleep and remain vigilant” while incubating. “I think that’s why it’s important to study sleep.

☆ Extreme sleep behavior documented in cute Antarctic chinstrap penguins

Guarding their nests is serious business for these medium-sized penguins, with predatory seabirds called brown skuas on the prowl. But this species, scientists said on Thursday, has devised an ingenious way of getting sufficient sleep without compromising vigilance. The researchers documented extreme sleep behavior in these flightless birds. "Penguins do not display any obvious negative consequence of sleep fragmentation," Libourel said. During incubation, skuas prey on penguin eggs, particularly on a colony's periphery.

☆ Why you snooze on the couch but then can’t sleep

So by the end of the day, sleep pressure is strong, your circadian rhythm is telling you it’s time for sleep and your environment is cozy and comfortable. Instead of having more than 16 hours of wakefulness behind you, you have just woken up and therefore have less sleep pressure. They start with light sleep, progress to deep sleep and then end with light sleep again. It might be easier to fall asleep on the couch, where there is less stress involved. This will ensure all the sleep pressure you build up during the day will be directed toward a deep sleep in your bed.

☆ It's okay to hit the snooze button. A new study shows it isn't bad for you and may even help you feel more alert.

Snoozers have the same sleep quality when they wake up immediately vs. when they snooze, a new study found. In fact, when people were allowed to snooze for 30 minutes, they were actually more alert. This contradicts what people previously thought about snoozing, that it hurts sleep quality. Next, the scientists closely monitored 31 regular snoozers in the lab to see what effects snoozing had on their sleep quality.

☆ Scientists see surprising brain activity in sleeping octopuses that could mean they dream like us

Scientists observed sleeping octopuses and saw their brains enter a deep sleep like ours. This deep sleep is similar to a dream state in mammals, so octopuses may also dream. For the study, scientists spied on multiple sleeping octopuses. By studying the octopus's brain activity, the team found that these cephalopods have similar active and quiet sleep cycles to us mammals and that certain periods of their active stage resembles rapid eye movement sleep. REM sleep is often when humans dream, leading scientists to wonder if octopuses may dream like us.

Experiencing negative changes in workplace leadership and fairness was associated with the strongest long-term impact on a worker's sleep. LumiNola/E+/Getty ImagesSleep problems included initiating or maintaining sleep, poor-quality sleep and daytime tiredness two to four times a week that lasted one month to three months. Within a two-year period of time, over half of the participants (53%) reported changes in their workplace environment. However, if the changes at work were negative, sleep issues increased — in fact 1 in 4 people in the study with a worse job environment developed problems getting enough rest. Having negative changes in the leadership and fairness sector was associated with the greatest long-term impact on sleep, more than negative changes in coworker relationships or collaboration, the study found.

When we've been awake for a long time, our sleep drive kicks in and tells us we need to sleep. During REM sleep, the cortex – responsible for cognition and emotion-processing – is activated in some regions and deactivated in others. After cycling through non-REM and REM sleep around 4 to 5 times, the basal forebrain and other structures receive signals to start exiting sleep. WHEN SLEEP GOES WRONGIn the U.S. alone, 50 to 70 million people experience some type of chronic sleep disorder, according to the American Academy of Sleep Medicine (AASM). In the United States, a list of board-certified sleep medicine physicians and accredited sleep disorders centers is available from the American Academy of Sleep Medicine.

What happens when we sleep Sleep itself has cycles, in which the brain and body move through phases, marked by varying brain activity. Moving into REM sleep A region in the upper brainstem kickstarts the move into REM sleep. Waking up After cycling through non-REM and REM sleep around 4 to 5 times, the basal forebrain and other structures receive signals to start exiting sleep. Then we transition back to lighter sleep, into REM sleep and back down again, and so on until we wake up. Tips for better sleep Good sleep habits can contribute to better sleep, studies have found.

☆ Insomnia is a $5 billion business — and this former sleep doctor thinks it's time for a new approach

Daniel Erichsen, founder of the Sleep Coach School Daniel ErichsenDaniel Erichsen spent about a decade as a sleep doctor, primarily seeing patients who were struggling with sleep apnea and insomnia. According to market research firm Imarc, the global insomnia market will hit $5.1 billion this year and climb to $6.1 billion by 2028. Other apps, including some backed by venture capital firms, promote cognitive behavioral therapy for insomnia, or CBT-I. That therapy is meant to change the way people think about sleep and incorporates behavior changes like sleep restriction and stimulus control. Kendall's message, which mirrors much of Erichsen's teachings, is that sleep is simple, but insomnia makes it seem complex.
