Sleep science, translated. Writing on rest, whole-body health, and the fight to make specialist care reach everyone.
A new bill in Congress would end the twice-yearly clock change, and the sleep medicine community is backing it. But the science points to a specific choice most people find surprising.
There's a master clock in your brain running a roughly 24-hour cycle that governs your sleep, your metabolism, your mood, and your heart. Here's how it works, and why keeping it in sync matters more than you'd think.
Your smartwatch or ring tracks your sleep every night. Some of those numbers are reliable and genuinely meaningful. Others swing wildly and deserve far less of your worry. Here's how to tell them apart.
Inattention, restlessness, brain fog, and trouble focusing can come from ADHD. They can also come from a breathing problem during sleep. Telling them apart matters more than most people realize.
That familiar 3 a.m. wake-up feels like something's wrong. Usually it isn't. Here's what your body is actually doing, and when it's worth a second look.
In December 2024, Zepbound became the first medication ever FDA-approved to treat obstructive sleep apnea. Here's what the science actually says, who it's for, and how it stacks up against Wegovy and the other GLP-1 drugs.
The four stages of sleep, decoded — and why the third one repairs more than your muscles.
The link between food and sleep runs both ways, and it may run through your gut. Here's what the science actually supports, and what's still just promising.
Waking repeatedly through the night is usually blamed on stress or bad sleep habits. For a surprising share of people, the real cause is a breathing problem they've never suspected — a pattern sleep medicine now calls COMISA.
Two people can have the identical sleep apnea number and need completely different treatments. The reason is the biology the AHI leaves out, and it's reshaping how sleep medicine is practiced.
Shallow breathing, oxygen dips, and micro-arousals cause the same damage as dramatic breathing pauses, and they're a big reason so many cases are missed.
Exhaustion, weight gain, and rising blood pressure in your late 40s are often treated as separate problems. In women entering perimenopause, they're frequently one connected story, and sleep apnea is the piece most often missed.
Almost everyone snores sometimes. For some people it's just noise, for others it's the most obvious symptom of a serious condition. Here's how to tell the difference.
Tens of millions of Americans have obstructive sleep apnea and don't know it. The cost, in health, dollars, and lives, is enormous, and it falls hardest on the people already least likely to get care.
A patient with a "normal" BMI can still carry dangerous visceral fat and moderate sleep apnea. For South Asians especially, the standard cutoffs were never built to catch it.
Poor sleep makes it harder to manage your weight. Excess weight makes it harder to sleep. Understanding the loop is the first step to breaking it.
Eight hours in bed isn't eight hours of rest. A look at the architecture of a restorative night.
A landmark 2023 JAMA analysis of 4,186 patients on what consistent treatment does — and doesn't — buy you.
Poor sleep raises insulin resistance. High blood sugar worsens sleep. How to break the cycle.
Why so much stubborn, hard-to-treat hypertension traces back to what happens in your airway at night, and what patients can do about it.
What a growing body of research reveals about the link between untreated sleep disorders and dementia risk — and what's still uncertain.
The hidden math behind America's sleep care gap, who gets left waiting, and why SOMOS is built so a patient in rural Virginia gets the same care as one in New York City.
Across rural America, the nearest accredited sleep lab can be hours away, if it exists at all. What the access data actually shows.
For decades, getting diagnosed with sleep apnea meant an expensive night wired up in a lab. That single requirement has quietly kept millions of people from ever finding out what's wrong.
