Short Wave: "Teen Sleep is Getting Wrecked by More than Just Phones"

Date: March 6, 2026
Hosts: Regina Barber, Katia Riddle
Guest: Scott Detrow (All Things Considered)
Episode Length: ~10 minutes

Episode Overview

In this lively science news roundup, Regina Barber, Katia Riddle, and guest Scott Detrow tackle three intriguing topics: the sharp decline in teen sleep (and why it’s not just phones to blame), new research on the mega-volatile Cascadia earthquake fault, and discoveries about prehistoric diets from ancient pottery. The conversation mixes humor, personal anecdotes, and clear science reporting, making complex topics accessible and engaging.

1. Teen Sleep Crisis: More Than Just Phones

Key Insights

• Recent research, published in JAMA, found that over three-quarters of U.S. high schoolers are not getting sufficient sleep (less than 7 hours per night) — a trend worsening across almost all demographics and surpassing previous years. ([02:35]–[02:51])
• Some teens reported getting less than five hours of sleep per night. The data come from the CDC’s Youth Risk Behavior Survey, which samples about 120,000 teens biannually. ([02:51]–[03:05])
• Teens with depression or suicidal thoughts tend to sleep even less, but sleep problems are widespread beyond these groups. ([03:23])
• The consequences of sleep deprivation are dire for teens: higher rates of depression, more car accidents, worse academic outcomes, difficulty getting jobs, maintaining relationships, and lower overall life satisfaction. ([03:48]–[04:16])
• Pediatrician Dr. Cora Collette Bruner (Seattle Children’s Hospital), who did not participate in the study, confirmed seeing these issues firsthand in her practice. ([03:48])
• The problem isn’t fully explained by individual behavior (like phones). Structural and environmental factors—such as early school start times—likely play a key role, suggesting the need for broad societal interventions. ([04:25]–[04:40])
• Later school start times are linked to improved sleep and mental health in teens. ([04:40])

Notable Quotes

• “The number of teenagers getting insufficient sleep...now it’s more than three quarters of these high school students.”
  — Regina Barber ([02:35])
• “If teens don’t get enough sleep, they’re more depressed, they get in more car accidents, they do worse at school, they don’t get good jobs, they don’t maintain relationships, they don’t have happy and productive lives.”
  — Dr. Cora Collette Bruner, quoted by Regina Barber ([03:48])
• “Since insufficient sleep seems to be a problem plaguing most teens, there must be structural environmental factors at play here.”
  — Katia Riddle ([04:25])

Memorable Moment

• Scott Detrow, chuckling about teen-parent distance:
  “That teen in my house…that doesn’t talk to me.”
  — Scott Detrow ([02:28])

2. The Looming ‘Big One’: Cascadia Megathrust Earthquake

Key Insights

• The Cascadia Subduction Zone, a major fault off the Pacific Northwest coast, poses risks of a catastrophic “megathrust” earthquake—one of the largest possible. ([04:54]–[05:25])
• New work from University of Washington researchers, published in Science Advances, used a decade of seafloor sensors to better map the fault’s mechanics. ([05:30]–[06:11])
• Insights revealed that the northern section of Cascadia is tightly locked and accruing stress, while the central section allows more fluid movement—meaning a future quake could unfold in new, unpredictable ways. ([06:11])
• These findings don’t immediately change who is at risk, but, as external earthquake scientist Chris Goldfinger explains, the scientific understanding of the zone’s catastrophic potential only emerged in the mid-1980s—and such detailed studies are vital for future preparedness. ([06:35])

Notable Quotes

• “That’s a big fault. It’s normal around here to keep a supply of earthquake emergency things in your garage, like bottled water and batteries.”
  — Katia Riddle ([04:55])
• “That data was gathered over a decade, and it gives us one of the most nuanced pictures yet of the Cascadia Fault.”
  — Regina Barber ([06:11])

3. Prehistoric Pottery Reveals Ancient Diets

Key Insights

• Scientists analyzed food residues on 4,000–8,000-year-old pots from northern Europe (Denmark to western Russia) and identified remnants of meals, shedding light on the diets of ancient hunter-gatherers. ([07:06]–[07:23])
• One notable discovery: a stew of fish and gelder roseberries—bitter berries that turn flavorful when cooked. This dish’s persistence across millennia demonstrates lost culinary traditions. ([07:34]–[08:00], [08:12])
• Archaeologist Crystal Dozier (Wichita State University) emphasized that many plants and even animals once eaten are gone from modern cuisine. ([08:12])
• The team even re-created some dishes: Oliver Craig (University of York, study author) described ancient flavors as “a bit flavorless,” but still found the berries "tasty," underscoring how food preferences are shaped by cultural context. ([08:46])

Notable Quotes

• “Our ancient, ancient, ancient ancestors were also not washing their dishes.”
  — Scott Detrow, on the benefits of old food crusts for science ([07:34])
• “There’s a lot of plants and even animals that we used to eat in the past as humans that have fallen out of our culinary traditions.”
  — Crystal Dozier (quoted by Katia Riddle) ([08:12])
• “Please, listeners, don’t eat random berries unless you know what they are, like, for real.”
  — Regina Barber ([08:20])

Important Segment Timestamps

• Cascadia Earthquake Fault Research: [04:49]–[07:01]
• Ancient Pottery & Prehistoric Diets: [07:01]–[09:08]

Final Thoughts & Takeaways

This episode underscores that:

• The teen sleep crisis is worsening, fueled by societal and structural trends—not just individual choices or technology.
• Improving sleep health for teens may require big changes, like school policies—not just nagging about bedtime.
• The potential for devastating earthquakes in the Pacific Northwest remains high, but science is making major strides in understanding the risks.
• Ancient culinary practices hold lessons for today, both in what we’ve lost and the possibilities for rediscovery.

As always, the hosts balance seriousness with humor, personal anecdotes, and a spirit of curiosity, making science news feel both important and relatable.
