Improving Sleep For Productivity

Sleep is the brain’s most powerful performance tool, and most people treat it like a negotiable expense. Neuroscience is blunt: when you cut sleep, the brain shifts into survival mode. Astrocytes prune more synapses. Microglia stay activated. The glymphatic “night shift” that clears waste runs poorly. You don’t just feel tired. You lose clarity, memory consolidation, and emotional control. Decisions get riskier. Empathy gets thinner. Creativity shrinks. It’s not hours you’re sacrificing. It’s executive function. High performance isn’t willpower, it’s architecture. The brain thrives in rhythm, not chaos. Try this for 7 days: • Wake at the same time daily (weekends too). Let bedtime adjust earlier. • Light before phone: 5–10 minutes of outdoor light upon waking. • Caffeine curfew: none after 2 PM. • Protect one 90-minute deep-work block after your best sleep. • Swap micro-scrolls for a 10–20 minute early-afternoon nap. • Dim lights and screens 60–90 minutes before bed. • Run a 10–15 minute wind-down ritual (shower/stretch/paper journal, same order every night). Small rituals, massive neurological returns. Leaders don’t optimize sleep because it’s soft; they optimize it because it’s leverage.

I have a confession: I’m a bit of a sleep evangelist. Late nights have never held any allure for me – the thought of dragging through the next day, foggy and tired, is enough to send me scurrying to bed in favor of late-night parties and events. While some revel in “burning the midnight oil,” I crave the clarity and focus that comes with a good night’s sleep. That’s why I loved the recent The Wall Street Journal article highlighting that the hottest new bedtime for twentysomethings is now 9 PM. They finally caught up to me 😊.    In honor of #WorldSleepDay, I think the article serves as an excellent reminder that simple changes (like incorporating an earlier bedtime) have promising potential to improve long-term health and mental wellbeing. Sleep is like a superpower that fuels our bodies and minds! Adequate shut eye strengthens our immune systems, boosts cognitive functions, and helps with emotional balance, too. It’s the foundation for a healthy body and a sharp mind.  My personal focus (some might call it an obsession) with a good night sleep is based on a few elements:    🔄 Keeping a consistent routine. It’s not always possible, like this morning, ironically. I was woken up by an operational alert at 4 AM! But getting into a good rhythm is the best feeling.    🧘🏽 Practicing meditation through mindful breathing. I do this for a few minutes before bed to decompress after my day.    🛏️ Creating a surrounding for optimal rest with lighting and comfortable bedding that minimize noise and light pollution.    🗓️ Following (or aspiring to) the 3-2-1 system, which is dinner about 3 hours before bedtime, no strenuous workout 2 hours prior, and no devices, email, or work 1 hour prior. I'm a work in progress on that last one.    📊 Tracking and studying my sleep carefully using the data to continuously learn and optimize my routine. There are so many great fitness and sleep trackers in the market today that can help us be more aware of the quality and quantity of our sleep.     On this World Sleep Day, lets champion sleep not just as a necessary bodily function but an important priority that propels us towards our best, most vibrant selves and the cornerstone of health and happiness.

Only 2% of Indians get 8+ hours of sleep daily. We also rank as the second-most sleep-deprived nation worldwide, after Japan. Sleep deprivation has almost become a part of our culture, where we often laugh it off, or embrace it as a part of the ‘hustle’. But it is serious issue that could be causing: - Fatigue and tiredness - Irritability and mood swings - Difficulty concentrating & focusing - Increased risk of obesity and diabetes - Impaired judgment & decision-making - Kidney disease, stroke, and hallucinations This takes a toll on your personal and professional life as well, putting productivity and relationships at risk. But the good news is that avoiding these effects is in your hands. All you need to do is use the S.L.E.E.P framework: ▶ 1. Schedule: Go to bed and wake up at consistent times, even on weekends. This regulates your body's internal clock, making it easier to fall asleep and wake up naturally. ▶ 2. Light: Dim the lights and avoid screens at least an hour before bedtime, as the blue light emitted by these devices can interfere with the production of sleep hormones. ▶ 3. Environment: Make sure your bedroom is quiet, dark, and cool. Consider using blackout curtains, earplugs, or a white noise machine to block out disruptive sounds. ▶ 4. Exercise: Aim for at least 30 minutes of moderate exercise early in the day, and avoid vigorous exercise close to bedtime as it can be stimulating. ▶ 5. Prioritise: Make sleep a priority by practicing good sleep hygiene habits: - Make sure your bed is supportive and comfortable - Avoid caffeine or large meals close to bedtime - Establish a relaxing night-time routine - Get some sun right after waking up Bonus Tip: If you can't fall asleep after 20 minutes, get out of bed and do a relaxing activity until you feel tired. Don't lie awake in bed worrying, as this can worsen sleep anxiety. How many hours do you sleep every day? #healthandwellness #workplacehealth #sleep

Your body clock predicts dementia 3 years before symptoms appear. New study: Weak circadian rhythm = 2.5x higher dementia risk. I've watched patients decline for 15 years. And I've never seen this connection made so clearly. The research (2,200 adults tracked for 3 years): Weak circadian rhythm: 2.5x higher dementia risk Activity peaking after 2:15 PM: 45% higher risk Strong, consistent rhythm: Protective What surprised me: They measured this with a simple chest monitor worn for 12 days. No brain scans. No blood tests. Just tracking when you're active versus at rest. Why your body clock matters for brain health: Disrupted rhythms increase brain inflammation ↳ Chronic inflammation damages neurons ↳ Accelerates amyloid buildup Poor circadian alignment interferes with sleep ↳ Brain clears toxic proteins during deep sleep ↳ Fragmented sleep = inadequate clearance Late activity peaks signal misalignment ↳ Body clock out of sync with natural light ↳ Hormonal systems get confused ↳ Metabolic dysfunction follows The patients I diagnose with dementia: Commonly have terrible sleep patterns. Going to bed at different times. Waking at random hours. Napping irregularly. Most active at night. I used to think this was a symptom of dementia. Turns out, it might be a cause. What counts as a strong circadian rhythm: Same bedtime every night (within 30 minutes) Same wake time every morning (yes, weekends too) Most active between 10 AM and 2 PM Minimal activity after 9 PM No long daytime naps The "night owl" problem: Being naturally active later isn't the issue. The issue is inconsistency and misalignment with light exposure. If you're consistently active 8 PM-midnight and sleep 2 AM-10 AM with good light exposure, that's fine. If you're sporadically active at all hours with no pattern, that's the problem. How to strengthen your circadian rhythm: 1. Light exposure timing ↳ Bright light (ideally sunlight) within 1 hour of waking ↳ 15-30 minutes minimum ↳ Signals to brain: "This is daytime" 2. Consistent sleep schedule ↳ Same time every night (even weekends) ↳ Non-negotiable ↳ More important than sleep duration 3. Time-restricted activity ↳ Exercise and social activity before 7 PM ↳ Dim lights after 8 PM ↳ Screen time minimized at night 4. Regular meal times ↳ Breakfast within 1 hour of waking ↳ Dinner 3 hours before bed ↳ No late-night snacking My clinical observation: The patients who maintain strong routines into their 80s and 90s stay sharper. The ones who let schedules drift show faster decline. This isn't about being rigid. It's about consistency. Your brain needs to know what time it is. ⁉️ Do you go to bed at the same time every night? ♻️ Repost if you believe simple routines beat complex interventions 👉 Follow me (Reza Hosseini Ghomi, MD, MSE) for evidence-based brain health strategies Citation: Wang W.

I once blanked during a $200K pitch meeting. → Not stage fright. → Sleep deprivation. After 14 days of 4-hour nights, I couldn't recall our core offering that I'd personally designed. The prospect's expression said it all: "If he can't remember his own product..." Sleep isn't a performance hack for founders. It's your primary strategic asset. The research most founders ignore: 1. Decision quality erodes before energy   • Your frontal cortex (judgment center) deteriorates first   • You make increasingly poor calls while feeling "fine" 2. Recovery follows a 3:1 ratio   • After my sleep collapse, it took 21 days to rebuild my strategic capacity   • Each week of deficit demands three weeks of repair 3. Leadership patterns create company culture   • When I implemented mandatory offline hours, error rate dropped 26%   • Your sleep discipline shapes organizational performance 4. The blind spot effect   • Sleep-deprived brains can't self-diagnose their impairment   • The biggest decisions deserve your clearest thinking The ultimate competitive edge isn't working harder. It's having clarity when your competitors are operating in a cognitive fog. Which is more important: your 11PM emails or your 9AM strategic decisions? ps: you might like this: https://lnkd.in/g7i6WdCq

Ever wake up just before your alarm? It might not be a coincidence… It turns out, our brains have a natural way of keeping track of time, an inborn “clock” mechanism, which is synchronised to light in our environment. It’s got the coolest name for such a tiny brain region: the suprachiasmatic nucleus (SCN) - literally, the group of cells (nucleus) above (supra) the optic chiasm (crossing). The SCN is essentially your brain’s “master clock” because it is responsible for coordinating our circadian rhythms. Light-sensitive cells in your eyes send signals to the SCN, which regulates melatonin - a hormone that makes us sleepy - via the pineal gland. Our species evolved to be diurnal, being active in the day and sleeping at night. As a result, daylight inhibits melatonin release, making us more alert. At night, the lack of light promotes melatonin release, making us sleepy. This is why for better sleep hygiene, experts often recommend limiting exposure to electronic devices for at least an hour before bedtime. The light from electronic devices can shift your body clock and this gets aggravated by heightened anxiety associated with doom scrolling -- neither of which helps your sleep. Want to support your brain’s internal clock? A few simple habits can make a big difference: 👉 Get natural sunlight in the morning. This helps reset your body clock. 👉 Stick to a consistent sleep schedule, even on weekends. 👉 Limit screens at least an hour before bed. 👉 Keep your bedroom dark and cool to promote better sleep. BTW, in teenagers melatonin starts to be produced later at night, which is why many teenagers don’t feel sleepy until much later in the evening. It’s also the reason they struggle to get up in the morning. For teens, going to school early is a bit like forcing them into a different time zone during the week and only letting them reset on weekends. When your teenager sleeps in on the weekends, bear in mind they are dealing with a genuine biological change in their circadian rhythm during the teenage years. So when you wake right before your alarm, blame (or credit!) your suprachiasmatic nucleus for being such a good time keeper! Understanding our biology helps us work with our natural rhythms rather than against them. How do you optimize your daily schedule around your circadian patterns?

Over the past couple of years, I've interviewed several sleep professors and physicians. They've shared a LOT of sleep tips with me. Being the lab rat psychologist I am, I tested them all. On myself. At this point, I have tried everything short of sleeping upside down like a bat. Many sleep tips failed to shift the dial. But three strategies genuinely transformed my sleep. Tip #1: Sleep LESS to sleep better This one surprised me. When I was struggling with insomnia, I was told: the worst thing you can do is spend more time in bed. Instead, less time in bed is the trick. Sleep restriction therapy (which I wrote about in The Health Habit) works like this: If you're only sleeping 6 hours but spending 9 hours in bed, restrict your bed time to 6 hours. Your sleep efficiency skyrockets. Then gradually increase it over the course of a few weeks. Tip #2: The 3-2-1 Rule 3 hours before bed: No more food 2 hours before bed: No more work 1 hour before bed: No screens (Kindle doesn't count) "But Amantha, I need to scroll the socials at 11pm!" (Said no well-rested person ever). Tip #3: Wake within the same 30-minute window every day Yes, even on weekends. I can hear you groaning. Let me explain. This is the cure to "social jetlag". Your circadian rhythm doesn't care that it's Saturday. When you sleep in for "just 2 more hours," you're essentially giving yourself jet lag. I wake between 6-6:30am every single day. No exceptions. The payoff? I fall asleep easily, wake naturally, and haven't needed an alarm in months (except when I have a ridiculously early How I Work podcast interview to get up for). What's your most effective sleep hack? Or are you still searching for the holy grail of good sleep? #SleepScience #ProductivityHacks #EvidenceBasedWellbeing

A study more people should know about: Simple “nudges” to reduce smartphone use improve wellbeing. 📚 The study: Olson et al. (2022), “A Nudge-Based Intervention to Reduce Problematic Smartphone Use: Randomised Controlled Trial” (published in The International Journal of Mental Health and Addiction) 🧪 What they did: The researchers randomly split two groups. One group was told to use their smartphones as usual. The other group was encouraged to use these simple strategies for 2-6 weeks:  1) Notifications. Disable non-essential notifications (sounds, banners, and vibration). 2) Accessibility. Keep your phone on silent (vibrate off), face down, out of sight, and out of reach when not in use throughout the day. 3) Unlocking. Disable Touch ID/Face ID (i.e. the fingerprint/face scanner to unlock your phone); use a password instead. 4) Sleep. Keep your phone on silent (vibrate off) and out of reach when going to bed (e.g. on the opposite side of the room). 5) Display. Turn down your phone’s brightness, set it to greyscale (black and white), and change the colour warmth to filter out blue light (i.e., turn on the “night shift” feature). 6) Social media. Hide social media and email apps (e.g. Instagram, SnapChat, Facebook, Gmail, Outlook) in a folder off of the home screen (or even delete them). 7) Computers. If you can do the task on a computer, try to keep it on the computer (e.g. social media, web search, or e-mail). 8) Relationships. Let your family, friends, or colleagues know that you will be replying less often unless they call you directly. 9)  Presence. Leave your phone at home when you do not need it (e.g. when getting groceries or going to the gym). 📈 The result: Among the group that used these strategies, the researchers saw: → Reduction in problematic smartphone use and screen time  → Reduction in depressive symptoms  → Improved sleep quality TL;DR The basic stuff works. Implement these basic strategies to hack back your phone. If you enjoyed this, download my 1-page playbook on how to build your Indistractable Phone: https://lnkd.in/ehvdikW9

I used to think hustle was the key to high performance. Then I learned the real secret: REST is the most powerful RGA. Most sellers grind themselves into dust chasing performance. But I’ve coached 100s of top performers—and the highest earners don’t work more hours. They master their energy. Here’s how I worked 40 hours a week (never work nights or weekends) and still outperformed 99% of reps: Let’s flip the script on what it takes to be a top performer in sales. Everyone talks about RGAs—Revenue Generating Activities. But no one talks about the energy required to do RGAs well. If you want to prospect with intensity, sell with presence, and close big deals— You need rest. At a mastermind recently, someone called it the “Ultimate RGA”: Rest Generating Activities. Because without rest, RGAs fall apart. You’ll be foggy. Reactive. Distracted. You’ll confuse activity with impact. Here’s how I train reps to recharge intentionally—so they can win without burnout: 1. Plan 4 Vacations a Year I pre-block 4 weeks off annually. They’re non-negotiable. It doesn’t matter if it’s Hawaii or your local mountain trail— The key is knowing you are unavailable. Not half-working. Not checking Slack. Fully present. Fully off. 2. Track and Protect Your Sleep I use a WHOOP. You can use anything. But if you're not sleeping 7+ hours, consistently, you’re underperforming. You can’t bring intensity to your calls when you’re running on fumes. Sleep is a performance multiplier. 3. Calendar Block Your Breaks My calendar is blocked 12–1 PM every day. Lunch with my wife. A walk. Or just quiet. Three hours of deep work → 1 hour of recovery → back for the final sprint. Burnout doesn’t happen from work. It happens from nonstop work. 4. Ruthless Time Boundaries I stop work at 5 PM most days. No nights. No weekends. Ever. You don’t need 70 hours a week to crush quota. You need to stop saying yes to distractions and start owning your schedule. Parkinson’s Law is real: The less time you give yourself, the more efficient you become. 5. Say No to Busy Work I use the 12 Week Year system. Everything I do ties back to a goal. Internal meetings? Minimized. Slack and email? Batched and time-boxed. If it doesn’t move pipeline or drive impact, I don’t touch it. If you’re working 60+ hours and still missing quota... It’s not your work ethic that’s broken. It’s your calendar. Stop measuring your week by hours worked. Start measuring it by energy invested in what matters. You don’t need to grind harder. You need to recharge better. Work less. Sell more. Live fully.

As a founder, I’ve let my sleep slide—and it’s cost me. Here’s how I’m fixing it in 5 simple steps to boost performance and longevity. 1. Set your wake time—this is non-negotiable. I’ve committed to a 5:30 AM wake-up time. This step is key because a consistent wake time anchors your entire sleep schedule. And I mean, it anchors the whole day. 2. Know your sleep needs and set a bedtime to match. Through trial and error, I’ve figured out that I need about 7.5 hours of sleep to feel rested, most of the time. This means my lights-out time is 10pm. Knowing your personal sleep requirement helps you set a firm bedtime, ensuring you’re getting the rest your body needs to perform at its best. 3. Create a ‘wind-down’ hour. The hour before bed is sacred—it’s when you need to start signaling to your brain that it’s time to sleep. This means no late-night social media scrolling or binge-watching intense shows for me. Instead, I’ve opted for calming activities like reading, meditation and breathwork. This practice helps ease your mind into sleep mode naturally. 4. Establish a food-sleep gap. I’ve started giving myself at least a 3-hour window between my last meal and bedtime. This helps prevent digestion from interfering with sleep. Some people find that a light, carb-based snack before bed, like a piece of fruit, can actually aid sleep, but the first step is creating that food-sleep gap and seeing how your body responds. 5. Focus solely on sleep for 30 days—nothing else. It’s tempting to overhaul your entire health routine all at once, but I’ve seen too many people burn out this way—many of my clients come to me after they’ve tried this. So, for the next 30 days, don’t worry about adding exercise, meditation, or food changes. Just focus on getting your sleep right. You might have a few off nights, but stick with it, and you’ll start to see a difference in how you feel and perform. I understand that not everyone has the luxury to set rigid sleep boundaries due to work and family commitments, but if you can make even small adjustments, they can have a big impact. Sleep isn’t just about rest; it’s the foundation for everything else in your life. So if you’re serious about improving your performance and longevity, start with sleep. How have you improved your sleep?
