Self-driving technology promises a future where commuting becomes productive, relaxing — maybe even nap-worthy. With advanced driver assistance systems (ADAS) becoming more common, some drivers feel tempted to recline the seat, close their eyes, and let the car do the work.
But sleeping in a self-driving car — especially today — carries serious risks.
Let’s break down why.
“I don’t dream.”
It’s a common claim. In almost any group conversation about sleep, someone will shrug and say they never dream at all. Meanwhile, others describe vivid adventures, nightmares, or cinematic storylines that feel more real than reality.
So what’s going on?
Do some people truly not dream — or is something else happening?
Sleep complaints are one of the most common concerns among older adults. Many assume that lighter, fragmented sleep is simply part of aging. But when sleep changes are persistent, severe, or accompanied by mood shifts, they may signal something deeper: depression.
In older adults, sleep disturbance is often not just a symptom of depression—it can be one of its earliest warning signs.
We often think of sleep as something influenced by stress, screen time, or caffeine. But what if one of the most powerful sleep aids is already sitting on your plate?
Emerging research suggests that a high-fiber diet may play a significant role in improving sleep quality. While fiber is usually associated with digestion and heart health, its impact reaches far beyond the gut.
Let’s explore how.
Nicotine pouches have surged in popularity as a smokeless alternative to cigarettes and vaping. They’re discreet, easy to use, and marketed as a “cleaner” option. But while they may avoid smoke-related toxins, nicotine itself is a potent stimulant—and that can significantly impact sleep.
Understanding the relationship between nicotine pouches and sleep can help users make informed decisions about timing, frequency, and overall health.
From smartwatches to rings to mattress sensors, sleep trackers have become a common part of nightly routines. With a glance at your phone each morning, you can see your “sleep score,” REM percentage, heart rate, and even estimated oxygen levels.
But do these devices actually improve sleep—or can they sometimes make it worse?
Let’s explore the benefits and the limitations.
In productivity culture, there’s a persistent belief that highly successful people thrive on just four hours of sleep. The story is seductive: sleep less, work more, achieve faster.
But biologically?
Four hours of sleep is not a badge of honor—it’s a stress test your brain and body eventually fail.
Let’s examine the myth and what science actually shows.
Melatonin has become one of the most widely used sleep aids in the world. Available over the counter in the United States, it’s often perceived as “natural” and therefore harmless.
But what happens when melatonin is used night after night—for months or even years?
Understanding the effects of prolonged melatonin use requires looking at how it works, what the evidence shows, and where caution is warranted.
As people age, sleep often becomes lighter, shorter, and more fragmented. While some changes in sleep architecture are normal with aging, chronic insomnia is not an inevitable part of growing older.
One often-overlooked contributor to elderly insomnia?
Sedentary living.
Reduced physical activity in later life has measurable effects on circadian rhythms, sleep pressure, mood, and overall sleep quality. Understanding this connection can empower older adults—and caregivers—to intervene effectively.
Many people have experienced a sudden jolt just as they’re drifting off to sleep—a brief, involuntary twitch that can feel like falling. These are called myoclonic jerks, and in most cases, they are completely normal.
But sometimes, myoclonic movements during sleep can signal something more serious—especially when they are frequent, clustered, or associated with other symptoms.
So how do you tell the difference between benign sleep jerks and seizure-related myoclonus?
Let’s break it down.
