Sleep And Health

One night of poor sleep leaves waste in your brain the next morning. Literally. Researchers recently discovered the brain’s waste-clearance system. And it’s reshaping how we think about Alzheimer’s prevention. For years, we thought sleep was about rest and memory. We were missing half the story. 𝗧𝗛𝗜𝗡𝗞 𝗢𝗙 𝗜𝗧 𝗟𝗜𝗞𝗘 𝗧𝗛𝗜𝗦 Your brain is a busy city. All day long, it produces waste. Every thought. Every decision. Every neuron firing. But unlike the rest of your body, the brain has no traditional lymphatic system. So it relies on a specialised network called the glymphatic system. Here’s the catch: ↳ It’s mostly active during deep sleep ↳ Miss that window, and yesterday’s waste sticks around ↳ Over time, that buildup matters 𝗛𝗘𝗥𝗘’𝗦 𝗧𝗛𝗘 𝗠𝗘𝗖𝗛𝗔𝗡𝗜𝗦𝗠 During deep sleep: ↳ Spaces between brain cells expand by ~60% ↳ Channels open ↳ Cerebrospinal fluid rushes through like a pressure wash ↳ Metabolic waste is flushed out ↳ Including beta-amyloid, the protein linked to Alzheimer’s plaques This is not happening when you’re scrolling in bed. It’s happening when you’re actually asleep. 𝗪𝗛𝗬 𝗧𝗛𝗜𝗦 𝗠𝗔𝗧𝗧𝗘𝗥𝗦 Even a single night of sleep deprivation has been shown to increase beta-amyloid levels in brain regions vulnerable to Alzheimer’s. Chronic poor sleep is associated with higher dementia risk, even after accounting for genetics. This isn’t about feeling tired. It’s about what quietly accumulates when the cleaning cycle is disrupted.

The health habit that's made the biggest difference for high-performing founders I work with. Here's the one that surprises people most. I've worked with founders who've overhauled their sleep, cleaned up their nutrition, built consistent exercise routines — They all report similar improvements: sharper thinking, better energy, more emotional bandwidth with their teams. But the one that consistently surprises people? The alcohol audit. Not abstinence. An audit. Most founders I assess are consuming 2–4 units per night — wine with dinner, a whisky to decompress, a beer during the evening call. It feels moderate. It reads as normal. But alcohol in that range is suppressing REM sleep by 20–30%, elevating baseline cortisol the following morning, and interfering with the hormonal recovery that happens during deep sleep. When founders reduce to 0–2 units maximum, and move those units to earlier in the evening, the sleep quality improvement alone is transformative. This isn't a moral position on alcohol. It's a performance conversation. What's one health variable you'd want to audit if you had the data in front of you?

Just one hour of sleep debt can take four days to recover. Not an all-nighter. Not a jet lag recovery. Just… one late night. And for most of us, that’s every Monday. We push through. Caffeine up. Call it discipline. But here’s the truth: your brain is still catching up from that “just one more email” energy four days later. So when Bryan Johnson the founder of Blueprint and one of the most measured humans alive decided to optimise his life, he started with this: SLEEP. Not supplements. Not cold plunges. Not AI routines. Just the thing most of us have… but misuse daily. What he does (and what’s working): ✅ Same sleep + wake time. Every day. No weekend exceptions. Circadian rhythm locked in. ✅ Red light only after sunset. Or blue blockers if you’re in a pinch. (Your phone’s night mode ≠ enough.) ✅ Digital wind-down, 1 hour before bed. No screens. Just calm. (Conversations count.) ✅ No food after lunch. Extreme? A little. But deeper sleep starts in your gut. ✅ Cool room. Zero light. Data tracking. His bedroom’s a sleep lab. But yours doesn’t need to be a fan + blackout curtain works. Why it matters: Because your ability to lead well to think clearly, to not snap at your team, to make better, longer-term decisions starts the night before. Lack of sleep doesn’t just make you tired. It makes you reactive. And distracted. And slowly, less like the leader (or person) you want to be. Here’s a gentler approach: Try one of these this week: → Set a wind-down alarm, not just a wake-up one → Dim your lights 90 mins before bed → Ditch the phone 30 mins before sleep → Eat dinner earlier → Go to bed at the same time 3 nights in a row Simple. Boring. But game-changing. So, what’s your current sleep habit? What’s helped you protect your rest lately? Share below. I’d love to hear the tiny tweaks that actually stick.

7 Things to stop 🛑 doing NOW if you want to build your business with less stress, overwhelm and sleepless nights Think about it, when was the answer to overwhelm ever to seek more things to do? NEVER. Yet when ever the to do list is mounting up along with the inbox and staff issues, the message preached to us is hustle. Yet given the opportunity to pause and take a 30,000 ft view there is no intelligent person who would look at you and the work ahead and point to inadequate effort as the cause or more effort as the answer. There are however a bunch of things that if you stopped doing them you would be amazed at the space opening up in your diary. 1. STOP telling people what to do. It seems quicker in the moment but tell someone what to do and bunch of really undesirable things happen. That person becomes a boomerang who keeps coming back to you for answers, feels incompetent and will soon become resentful. Instead master supporting others to their own clarity and create an employee who feels valued, competent and trusted. 2. STOP accepting back to back meetings. It might seem productive. But you aren’t paid for productivity you are paid to make high quality decisions. Instead make sure meetings have at least 15 minute between them and make sure they follow a simple system that supports clarity and decision making. 3. STOP checking your email between meetings. Your constantly availability and responses are creating a world of urgency around you. Instead take the time to create a clear email strategy that doesn’t buy into other peoples urgency and aligns with the mission of the business and your priorities and stick to that. 4. STOP keeping the challenges and obstacles that arose today in your head until tomorrow causing you to ruminate, map out scenarios and assumptions in your head making sleep difficult. Instead get that stuff down on paper and allow your subconscious to explore it while you sleep soundly. 5. STOP working in the last hour before bed revving up your nervous system before bed making sleep shallow and disturbed. Instead prioritise high quality sleep in order to prioritise high quality thinking and work every day. 6. STOP keeping your phone with you 24/7 if your phone is with you you’re on call. If you’re on call then your nervous system is on alert and you aren’t recovering. Instead create a strict phone time table and stick to it. Your brain will cry tears of joy. 7. STOP rushing into your day feeling however you feel and dealing with what ever comes up first on the to do list. Being intent to put in as many hours as possible. Your job is not to put in hours or get anyone else to either. Your job is to get the business in high performance mode and that starts by getting yourself in high performance mode. Instead fill your morning with energy and clarity building practises before you let the day come rushing in. Overwhelm is a signal that the way you’re working isn’t working. What will you change first?

You won’t find “hacks” or quick fixes in my keynotes, or coaching programs. Spoiler alert: there are no shortcuts when it comes to sustainable performance or wellbeing. The idea that you can ice-bath, supplement, or 5am-club your way out of chronic stress, poor sleep, or a poor diet is seductive, but it’s simply not true. I don’t subscribe to or share “hacks” because they imply there’s a clever workaround for the fundamentals. There isn’t. Working with your biological blueprint, what I refer to as your Human Operating System (hOS🧠)—isn’t always sexy or Instagrammable and often can't be distilled in a 30-word "hack". You can’t meditate your way out of skipping meals and no amount of red-light therapy will undo the impact of late-night emails and fragmented sleep. The real game-changers? They’re almost always the boring, science-backed basics because as I often say,"The basics work, if you work the basics": 😴 Consistent, high-quality sleep (not just more hours, but better quality sleep through consistent sleep and wake times, morning sunlight, predictable wind down routines and managing your daytime stress); 🏃🏼♀️ Moving your body daily (in ways that fit your life, not someone else’s highlight reel and including incidental movement throughout the day to break up and nullify the impact of our increasingly sedentary lives); ⌚️ Building a fortress around your focus in your natural “power zone” hours (hello, chronotype. Your FQ is now more important than your IQ and EQ); 👯♂️ Prioritising human connection (IRL catch ups, not just sending funny memes to your friends); and 🛏️ Prioritising real recovery and downtime (not just a week off, but small, daily, peak-performance pit-stops). These foundational habits work, if you work them. They require intention, consistency and a willingness to play the long game. It isn’t glamorous, but it’s what actually moves the needle. So if you’re tired of chasing the next shiny “hack,” maybe it’s time to come back to the basics. Your hOS will thank you—and so will your future self.

Checking WhatsApp before getting up → starts your day reactive Opening Instagram 20+ times → doses of envy and insecurity Replying to emails at lunch → trains your brain to never rest Sharing every meal online → eating for the camera, not yourself Arguing in comment sections → free daily cortisol Binge-watching “comfort shows” → numbs emotions you should feel Breaking news every hour → constant low-level panic Dating apps for boredom → attachment system overload Tracking every step and calorie → health anxiety in disguise Slack/Teams open past 9 PM → body stays “on call” Filling silence with podcasts → no space for your own thoughts We are burning out silently, one “normal” habit at a time. Mental health suffers. Gut health tanks. Sleep disappears. And what’s worse? We think it’s fine because everyone else is doing the same. Now imagine this instead: Morning sunlight and stillness → calmer nervous system Instagram once a day → more focus, less comparison Lunch without screens → better digestion, mental reset Cooking for yourself → reconnects you with your body Logging off online fights → protects your peace One intentional show → restores energy, not drains it News once a day → awareness without anxiety Offline meetups → healthier connection Listening to your body → true health tracking Logging off work on time → body knows it’s safe to rest Daily silence → space for your own thoughts Your nervous system doesn’t care about trends, feeds, or notifications. It only remembers your habits. Choose them before they choose your future.

Poor sleep is costing you more than energy. It is costing you clarity when sharp judgment matters. It is costing you patience in conversations that require steadiness. It is costing you focus, emotional regulation, recovery, and the ability to lead at your highest level. For leaders, sleep is not a luxury. It is part of how you think, decide, and perform under pressure. Two practical shifts can make a meaningful difference: 𝟭. 𝗥𝗲𝗺𝗼𝘃𝗲 𝗲𝗹𝗲𝗰𝘁𝗿𝗼𝗻𝗶𝗰𝘀 𝗳𝗿𝗼𝗺 𝘁𝗵𝗲 𝗯𝗲𝗱𝗿𝗼𝗼𝗺. If your bedroom is filled with screens, alerts, email, news, and late-night scrolling, your brain does not read that environment as recovery. It reads it as stimulation. Keep the room dark, quiet, and free from the devices that keep you switched on. If you wake up in the night, do not reach for your phone. 𝟮. 𝗚𝗲𝘁 𝗼𝘂𝘁 𝗼𝗳 𝘄𝗼𝗿𝗸 𝗺𝗼𝗱𝗲 𝗯𝗲𝗳𝗼𝗿𝗲 𝘆𝗼𝘂 𝗴𝗲𝘁 𝗶𝗻𝘁𝗼 𝗯𝗲𝗱. A lot of sleep issues start here. The body is in bed, but the mind is still in performance mode, reviewing, solving, anticipating, and carrying the day forward. In that state, sleep stays shallow because the brain has not fully shifted from alertness into recovery. Before bed, create a transition your brain and body can trust. Slow your breathing. Put your attention on your heart. Bring up a renewing feeling like calm, gratitude, or peace. The goal is not to force sleep. The goal is to stop sending your body the message that it still needs to stay on guard. When you slow your breathing you signal the brain to shift from high beta brain waves to low beta and eventually to alpha, preparing you for deep restorative sleep.

Feel like you’re stuck in light sleep all night and never wake up truly rested? You’re not imagining it. Even if you’re in bed for 7 to 8 hours, poor sleep quality can leave you feeling groggy, foggy, and drained. Here’s what might be keeping you from getting into deep, restorative sleep and what to do about it: 🧠 Stress overload: If your brain stays on high alert, your body won’t fully relax. ✅️ Build in 10 to 15 minutes of true wind down time before bed. No screens, no planning, no multitasking. 💡 Too much light at night: Bright lights, especially blue light, suppress melatonin. ✅️ Dim household lights at least an hour before bed and avoid scrolling before sleep. 🌡️ Overheating: Your core temperature needs to drop for deep sleep to kick in. ✅️ Set your bedroom temp to around 65 to 68 degrees and use breathable bedding. 🍷 Late alcohol: It may help you fall asleep but disrupts deeper sleep stages. ✅️ Stop alcohol intake at least 3 hours before bed. 🛏️ Inconsistent sleep times: Your body’s sleep drive relies on rhythm. ✅️ Stick to a consistent sleep and wake time, even on weekends. Deep sleep is what powers your focus, mood, immune system, and performance. If you’re stuck in light sleep, these small shifts can make a real difference. Have you tried any of these? What’s helped the most?

🧊 Stay cool to stay asleep. Yesterday, we talked about how your body has to cool down to power down. Once you’re powered down, the next challenge is staying asleep—and that depends on keeping your core temperature low and stable. 🌙 Why it matters: During deep sleep, your body continues to shed heat. Even small rises in temperature can pull you out of slow-wave sleep and into lighter, more fragmented stages. 📊 The science: • Best ambient temperature: 60–67°F (15–19°C) for most adults. • Warmer rooms shorten REM, lower HRV, and reduce next-day alertness. • Perimenopause: Hormonal fluctuations (especially declining estrogen) disrupt the hypothalamic thermostat, narrowing the normal thermal buffer and triggering night sweats/hot flashes that destabilize core-temperature regulation during sleep. 🔥 Why late-night habits raise your core temperature: • Heavy meals: The thermic effect of food increases metabolic heat during digestion. • Intense workouts: Elevated muscle metabolism and circulation delay cooling. • Alcohol: Causes blood vessels to dilate, making you feel warm initially, but later triggers rebound heating and restless sleep. 🛏️ Practical cool-downs: • Set your thermostat before bed to cool the room. • Choose breathable sheets—cotton, linen, or bamboo. • Keep air circulating with a fan or cracked window. • If you run warm, consider smart cooling tech like the BedJet (airflow), ChiliPad / Dock Pro (water-cooled pad), or Eight Sleep Pod (smart temperature control and HRV tracking). 💡 You fall asleep by cooling down. You stay asleep by staying cool. 💭 Have you noticed how just a few degrees’ difference can change your sleep quality? #SleepOptimization #Recovery #Performance #HRV #RestorativeSleep #CircadianHealth #Menopause #Longevity #MetabolicHealth #Biohacking #PhysicianHealth

I slept terribly for years. Then I treated sleep like a professional skill. Everything changed. Most professionals over 40 treat sleep as leftover time after everything else. • Emails until 11 PM. • Phone in bed. • Fall asleep when exhaustion wins. • Wake up tired. • Repeat. That’s not sleeping. That’s passing out from depletion. Here are 10 habits that fix it. In order of impact. ✔️Decide you’re a professional sleeper. Sleep isn’t a luxury earned after productivity. It’s the platform that makes productivity possible. ✔️Non-negotiable bedtime. Same time, 7 nights. Your circadian rhythm doesn’t know it’s Saturday. Shifting your window by 2 hours on weekends is free jet lag. ✔️Wind-down ritual. 30 to 60 minutes before bed. No screens. No work. No arguments. Reading, stretching, hot shower. Your nervous system needs a clear signal the day is over. ✔️Stop eating 3 hours before bed. Late meals keep insulin elevated and digestion active. Earlier you finish, deeper you sleep. Emergency late option: Greek yogurt only. ✔️Caffeine curfew at 1 PM. After 40, caffeine’s half-life extends. That 3 PM espresso is in your blood at midnight. You think you’re sleeping. Your nervous system isn’t. ✔️Alcohol destroys sleep. It sedates, which feels like sleeping. But sedation and sleep are neurologically different. Alcohol fragments REM, the phase where your brain consolidates memory. Nightly drinks are sabotage disguised as relaxation. ✔️Control light. Blue light suppresses melatonin up to 50 percent. Blockers after 7 PM. Blackout curtains. Sleep mask. Your bedroom should be a cave. ✔️Cool the room. Deep sleep requires core temperature to drop 2 to 3 degrees. Bedroom at 65 to 68 degrees. Hot shower 90 minutes before bed forces the drop. ✔️Bright light in the morning. Sunlight within 30 minutes of waking sets your circadian clock for the day. If indoors, a 10,000 lux light box works. Morning light makes nighttime melatonin stronger. ✔️Track it. Smartwatch, Oura, or WHOOP shows how habits affect sleep stages. Without data, you’re guessing. With it, you’re optimizing. Sleep isn’t recovery from your day. It’s the foundation your next day is built on. Fix these 10 and training works better, fat loss accelerates, and your brain performs like it did a decade ago. How many of these 10 are you doing?🤔 ✅ Save this. Start with habit 5 tonight. One PM caffeine cutoff. Report back in 7 days
