Sleeping Pills May Disrupt the Brain’s Natural Cleaning System, New Study Finds

This system plays a crucial role in removing harmful waste products from the brain, a process essential for mental health.

Now, a Danish study led by postdoc researcher Natalie Hauglund from the University of Copenhagen and the University of Oxford suggests that sleeping pills may interfere with this cleaning process, potentially increasing the risk of severe diseases like Alzheimer’s.

The Brain’s “Dishwasher”

The brain has its own cleaning mechanism, known as the glymphatic system.

During sleep, this system flushes out waste through cerebrospinal fluid, preventing the accumulation of harmful proteins linked to neurological disorders like Alzheimer’s.

A key player in this process is the molecule noradrenaline.

During deep sleep, noradrenaline is released in rhythmic waves, acting like a pump that drives fluid flow through the brain.

But what happens when you take sleeping pills?

According to the new study, published in the journal Cell, the sleeping drug Zolpidem reduces noradrenaline waves by 50 percent in mice.

This significantly weakens fluid circulation in the brain, impairing its cleaning function.

The results are concerning because waste that isn’t properly cleared can accumulate over time, forming sticky protein plaques—one of the hallmarks of Alzheimer’s disease.

Can Findings in Mice Apply to Humans?

Since the study was conducted on mice, an important question arises: Can these findings be applied to humans?

Professor Axel Kornerup Hansen from the University of Copenhagen believes there is good reason to think so.

Previous research has shown that humans have the same physiological mechanisms for brain cleaning.

However, he points out that dosage and effects of sleeping medication may differ between humans and mice.

More studies are needed to confirm the connection, but sleep researcher Poul Jennum urges caution:

“The effect that sleeping medication has on glymphatic flow is an important finding. But this is just a small part of the picture. Sleeping pills influence an incredibly complex network that also involves cardiovascular function, breathing, mood, and much more,” he told Videnskab.dk.

Scientists Reveal: Why We Keep Coughing After an Infection

A cough is more than just an annoying reflex—it’s the body’s defense mechanism against foreign particles and potential threats in the airways. But why does the cough often linger long after we’ve recovered? Research points to a surprising explanation: the infection’s impact on the nervous system.

Coughing – The Body’s Alarm System

Coughing is triggered by nerves in the airways equipped with receptors that respond to various stimuli, from cold air to capsaicin, the spicy compound in chili peppers. When these receptors detect an irritant, they send signals to the brain, which then decides whether a cough is necessary.

However, many people continue coughing even after their infection has cleared. Scientists are still searching for a definitive answer, but they have uncovered a key mechanism: inflammation and hypersensitive nerves.

Inflammation and Hypersensitive Nerves

When we get sick, viral infections provoke an inflammatory response in the body that can make the nerves in our airways hypersensitive. This heightened sensitivity can persist for weeks, causing coughing from even minor irritations, such as cold air or laughter.

A 2016 study found that even dead viruses—neutralized with UV light—could increase the number of TRPV1 receptors in lab-grown human cells. These receptors respond to irritants and can make something as simple as a deep breath trigger a cough. This suggests that it’s not necessarily the active virus itself but rather the traces it leaves behind that can prolong the cough.

How Long Does a Cough Last?

According to experts like Michael Shiloh from UT Southwestern Medical Center, a cough typically resolves within two to three weeks. However, in some cases, it can persist for up to eight weeks—or even longer.

If a cough lasts this long or is accompanied by symptoms such as fever, bloody phlegm, weight loss, or shortness of breath, medical attention should be sought.
