What Is Sleep Hypopnea? Could It Be Affecting You?

Poor sleep can affect every part of your life, from how alert you feel in the morning to how well your body protects itself from long-term health problems. Many assume their restless nights, morning headaches, or daytime fatigue are due to stress or a bad mattress. But in some cases, the cause is a sleep disorder you may not have heard much about: sleep hypopnea. What Is Sleep Hypopnea? Sleep hypopnea is a sleep-related breathing disorder. It occurs when one's breathing becomes unusually shallow during sleep. Instead of smooth, normal airflow, the upper airway becomes partially blocked, reducing the amount of air one takes in. This decrease in airflow means less oxygen reaches your blood. Over time, repeated episodes can lower your blood oxygen levels, strain your body, and prevent you from reaching restorative sleep stages. The American Academy of Sleep Medicine defines hypopnea as a partial reduction in airflow...

Mattresses in Space: What Do Astronauts Sleep On Up There?

Mattresses in Space: What Do Astronauts Sleep On Up There?

In a recent article, we explored how a NASA invention for astronauts turned into memory foam mattresses that improve our sleep every night (see From NASA to Your Bedroom: The Evolution of Memory Foam Mattresses). But what about the astronauts themselves? Up on the International Space Station (ISS), crew members aren’t dozing on king-size beds; they’re cocooned in sleeping bags attached to the wall as they hurtle around Earth at 17,500 mph. In fact, an astronaut on the ISS experiences 16 sunrises and sunsets every 24 hours, making a “normal” night’s sleep a bit of a cosmic challenge. It sounds wild, yet many astronauts insist that sleeping in space can be extremely comfortable – perhaps even more comfortable than on Earth – once you get used to it. How Astronauts Go to Bed Astronauts don’t use traditional mattresses in space. Instead, each crew member sleeps solo in a small, closet-like...

Jet Lag Recovery: Can Your Mattress Help You Adjust Faster?

Jet Lag Recovery: Can Your Mattress Help You Adjust Faster?

Jet lag is essentially a circadian rhythm sleep disorder. Normally, your body clock is tuned to the 24-hour day–night cycle: daylight keeps you awake, and darkness tells your brain it’s time for sleep. But when you zoom across several time zones in a matter of hours, your internal clock can’t instantly catch up. For example, if you fly from New York to London and arrive at 11 PM local time, your body might still feel like its 6 PM back in New York, making it hard to fall asleep. Your body then goes through a “recouping” phase – sometimes linked to the growing pains of adjusting to a new schedule. The adjustment takes time. In practice, your circadian clock shifts by roughly 1–1.5 hours per day as you reset to the new zone. This means if you cross, say, 6 time zones, it could take around 4–6 days to adapt...

Napping Like a Pro: How Power Naps Enhance Productivity and Health

Napping Like a Pro: How Power Naps Enhance Productivity and Health

You know that moment, when your brain checks out, your eyelids get heavy, and everything just feels… slower? It usually hits right after lunch, and no, it’s not just you. Turns out, your body’s wired for a midday dip in energy. And the fix isn’t always another cup of coffee. Sometimes, what you really need is a quick nap. That’s why companies like Google and Ben & Jerry’s have built nap rooms into their offices. They know what NASA discovered: a short nap can boost alertness by 54% and improve performance by 34%. Why Power Naps Work The magic of power naps lie in their timing. When you rest for a short period, usually between 10 and 20 minutes, your brain stays in the lighter stages of sleep. Your body relaxes, your mind clears, and stress levels drop. This short burst of rest helps improve focus, lift your mood, and...

Sleep Chronotypes: Are You a Bear, Wolf, Lion, or Dolphin?

Sleep Chronotypes: Are You a Bear, Wolf, Lion, or Dolphin?

Not everyone is wired to wake up early, fall asleep quickly, or feel energized at 9 a.m. sharp. And that’s perfectly okay. Thanks to the work of clinical psychologist and sleep expert Dr. Michael Breus, we now understand that people fall into four distinct sleep chronotypes; Bear, Wolf, Lion, and Dolphin. These categories explain your natural sleep-wake cycle, energy highs and lows, and even your ideal mattress type. So if you've ever wondered why you're ready to start the day while your partner is hitting snooze for the third time, or why your productivity peaks just before midnight, your sleep chronotype might hold the answer. Let’s dive into each chronotype, what it means for your lifestyle, and how to choose the perfect mattress for your unique rhythm. What Are Sleep Chronotypes? Sleep chronotypes are biological labels for how your circadian rhythm—your body’s internal clock—operates. This rhythm governs when you naturally...

How Your Mattress Affects Your Immune System (Yes, Really!)

How Your Mattress Affects Your Immune System (Yes, Really!)

Numerous studies have established a connection between a good night's sleep and health. It’s when your body repairs, strengthens defenses, and fights off infections. When you don’t get quality sleep, everything from your energy levels to your immune system takes a hit. Your body produces fewer infection-fighting cells, inflammation increases, and you become more vulnerable to colds, flu, and other illnesses. Poor sleep can result from many factors – but your mattress is probably the biggest culprit. If your mattress is old, unsupportive, or filled with allergens, it can disrupt your sleep differently. And when it does, it’s a direct hit to your immune system. The Role of Sleep in Immune Health Sleep plays a critical role in keeping your immune system functioning correctly. While you sleep, your body produces and releases cytokines—proteins that help regulate immunity and inflammation. These cytokines are essential for responding to infections and reducing inflammation....
