Sleep isn’t a luxury you negotiate with; it’s the biological foundation every other health habit is built on, and most people are getting far less of it than they think.

Dr. Andrew Fix revisits one of the show’s most foundational episodes for Better Sleep Month, and the timing feels personal. A new baby at home has a way of clarifying just how much everything falls apart when sleep does. Drawing from Matthew Walker’s landmark book Why We Sleep, this episode makes a compelling case that sleep deprivation isn’t just fatigue. It’s a direct line to cancer, cardiovascular disease, dementia, weight gain, and a compromised immune system.

Here’s a question worth sitting with: if you went to bed at 10 and woke up at 6, did you actually get eight hours of sleep? Probably not. Time in bed and time asleep are not the same thing, and that gap is where most people are quietly losing ground.

Dr. Fix gets practical without being prescriptive. A consistent sleep schedule, a cooler and darker room, cutting caffeine earlier than feels necessary, and keeping alcohol away from bedtime are the kinds of shifts that build real resilience over time. He also draws a connection that often gets overlooked in fitness culture: sleep is where recovery actually happens, and poor sleep throws off the hormones that regulate hunger, making weight management an uphill battle no matter how clean your diet is or how early you get to the gym.

What would change about your daily habits if you treated sleep as seriously as your workouts or your nutrition? That’s the real question this episode leaves you with.

Quotes

• “I think it’s a shock to nobody that sleep is the most important thing in our lives. If we don’t get enough of it, pretty much every major function of our body is going to suffer.” (02:37 | Dr. Andrew Fix)
• “The amount of time that you spend in bed that you think you are asleep does not equal or correlate to the amount of time that you actually sleep.” ( 06:27 | Dr. Andrew Fix)
• “I do have a change in my sleep quality when I cut that caffeine out earlier. So, avoiding caffeine and nicotine, in theory, will help with your sleep quality.” (13:52 | Dr. Andrew Fix)
• “You want your brain to be planning to go to bed when you get in bed. You want your body’s cycle to be just so in tune with, ‘Oh, this is where I come when I want to go to sleep.’” (20:19 | Dr. Andrew Fix)
• “All of the professional athletes that we watch on television and whatnot, I can tell you that they are putting a much higher emphasis on sleep than we do in our normal lives.” (31:59 | Dr. Andrew Fix)

The post 225. The Code to Sleep Hygiene appeared first on Physio Room.

Your mattress may be the most important performance tool in your life and most people are choosing it based on marketing instead of measurable impact on sleep, recovery, and long-term health.

Sleep drives everything. Cognitive sharpness. Physical recovery. Emotional regulation. Longevity. Yet most people approach mattress shopping with guesswork and brand promises rather than clear performance criteria. Dr. Andrew Fix sits down with Derek Hales, founder of NapLab, to unpack how better sleep starts with better decisions about what you lie on every night.

They move past hype and focus on outcomes. Are you waking up sore? Do you feel restored in the morning? Is your mattress actually supporting your body type and sleep position? Derek shares practical insights from testing hundreds of mattresses and consulting with thousands of sleepers, including why medium-firm works for most people, how couples can solve conflicting firmness preferences, and why mattress weight may be one of the simplest indicators of build quality.

The conversation also highlights overlooked factors such as foundation support, pillow height, and how different sleep positions affect spinal alignment. The bigger takeaway is clear. If sleep is the foundation of performance and health span, then your mattress is not a casual purchase. It is infrastructure.

Quotes

• “If we’re not getting good sleep and the mattress is the cause, we need to get a solution.” (05:09 | Derek Hales)
• “I really don’t think there is a sort of best mattress for everybody. There is the best mattress for you.” (07:11 | Derek Hales)
• “Sleep is the healer. It’s how the body restores itself, and how the body recovers.” (12:48 | Derek Hales)
• “When you sleep deeper, longer, better, health outcomes are better, physical outcomes are better, emotional well-being is better.” (19:02 | Derek Hales)
• “Sleep is the foundation of our health.” (21:50 | Derek Hales)

The post 214. Choosing the Perfect Mattress for You | Derek Hales appeared first on Physio Room.

On this episode of The Code, Dr. Andrew Fix walks us through three easily implementable changes we can make to improve the quality of our sleep. They include making your sleep area as dark and quiet as possible (including cutting down on screen time), keeping the bedroom cool, and avoiding caffeine and alcohol past a certain hour. He offers tips on products for cooling, light blocking, and noise cancelation, as well as tips for balancing a social life with quality sleep.

Everyone has varying schedules, spouses or kids whose needs vary, and lives that don’t always go according to plan. Still, as much consistency as possible is key. Committing to a sleep schedule, including on the weekend, is the first step in getting quality–which is far more important than quantity– sleep.

Join Dr. Andrew to learn what times Dr. Andrew recommends sleeping and waking, what the optimal temperature in the bedroom should be, and the book by Dr. Matthew Walker that inspired this episode.

Quotes

• “Instead of trying to implement 15 different ideas, what if I just wanted to focus on one or two, which ones should I focus on that are going to have the biggest impact on my sleep.” (2:36-2:46 | Dr. Andrew)

• “I chose these three because they’re ones that are, for the most part, totally within your control, (3:52-3:57 | Dr. Andrew)

• “Every moment that I spend in bed, I’m not actually sleeping. I’m spending a portion of that time sleeping, but not the whole time.” (6:15-6:22 | Dr. Andrew)

• “We’re not talking about helping you feel drowsy at night. A lot of people feel like if they have a nightcap, it helps them fall asleep. We’re talking about increasing the quality of sleep that you get.” (11:46-11:54 | Dr. Andrew)
