I achieved the best recorded sleep score in history. Eight months of perfect, 100% sleep. Spent a year learning how to do it. Here are 10 habits that fixed my terrible sleep... 🧵

1/ If you sleep less than 7 hours a night, read this… + One 4-hour night reduces cancer-fighting immune cells by 70% + Chronic 6-hour nights make you 4.2x more likely to catch colds + 18-24 hours awake = 0.05-0.1% blood alcohol level equivalent (0.08% is legally drunk) Sleep loss also impairs cognition, slows reflexes, and leads to poor decisions. It's tied to heart disease, diabetes, obesity, anxiety, depression and a weak immune system. Here're 10 habits that improved my sleep... P.S. I've made a free sleep checklist too, so read till the end.

1/ Reframe Your Identity: You are a professional sleeper Make sleep your #1 appointment in your calendar. Nothing influences your conscious or subconscious existence more. + Plan your day around sleep. + Ignore those who say sleep is for the weak. They’re drunk. + Get support from others by explaining your priorities. Most people are drunk from sleep deprivation. Sleep will make you a top performer.

2/ Have a Consistent Bedtime Choose a non-negotiable bedtime for 7-9 hours in bed each night. + Be consistent, even on weekends. + Use a wearable or journal to track You’re on time for work meetings. Be on time for your bedtime and respect yourself.

4/ Eat Your Last Meal Early For years I tested my eating times on sleep quality and landed at 11 am being the best for high quality sleep. Not everyone can do this, but here are the general guidelines: + Avoid eating within 3-4 hours of bedtime + Have your largest meal in the middle of the day + When socializing late, choose light options like veggies + You can experiment extending to eating your final meal 4 and 6 hours before bed to assess how it effects your sleep quality. + By the time I go to bed at 8:30 pm, primary digestion is done and my resting heart rate is around 47-49 bpm. Here’s why: Eating close to bed creates large metabolic demands on your body, causes blood glucose fluctuations, reduces melatonin production, and disrupts your body’s natural process of lowering core body temperature.

5/ Discontinue Stimulants After Noon Try to avoid caffeine and other stimulants well before sleep. + Skip alcohol near bedtime - it disrupts sleep + Each person has a unique tolerance to stimulants so find your right cut-off time + Avoid high arousal settings close to bedtime

6/ I don’t consume caffeine or alcohol. They each disrupt my mood and negatively affect my sleep. But that’s me. You can find what’s right for you.

7/ Regulate Your Bedroom Temperature: + Explore your ideal bedroom temperature 60-77°F (15-25°C). + Consider a temperature controlled mattress to regulate bed surface temp + Use breathable cotton or linen sheets and lightweight sleepwear + Consider taking a warm bath before bed. Experiment and track your sleep patterns with a journal or sleep tracker.

9/ Get Sunlight Within 15 Min of Waking Get outside within the first 15-30 minutes of waking to set your circadian rhythm and boost mood. If you’re up before the sunrise, use a 10,000 lux light

10/ Track Your Sleep Metrics Metrics to follow: HRV, body temp, respiration rate, REM & deep sleep. I use Whoop and EightSleep. Other sleep trackers are fine too. + Experiment with bedtimes, routines, room temps & find what works + Track data across seasons and when traveling to troubleshoot + Use a sleep journal, tracker, or checklist. You’ll improve what you measure.

12/ Many of our social activities currently take place late at night, usually after most people's bedtimes. It's within our power to reset norms so that we can do fun things together, like music festivals, dinners and dance parties, and still get great sleep. I stayed out late one night for a music festival and paid the price...

This is great, thank you 🙏 I have also found the Sleep Cycle app to be helpful for tracking sleep trends and optimizing my ideal sleep time. Do you recommend any food or drinks to aid sleep?

Here’s how to ACTUALLY block blue light on your iPhone, most of the apps are actually just filtering a narrow spectrum. This method puts it into pure red light mode. This hack has helped my sleep immeasurably. Step 1: Settings > Accessibility > Display and Text Size > Color Filters Step 2: Turn on color filter > Check “Color Tint” Step 3: Slide the “Intensity” and “Hue” bars all the way to the right (this is maximum red and filters all blue light) Step 4: Go back two screens to “accessibility” then click “Accessibility Shortcut” Step 5: Check “Color Filters” - this turns on the “triple click” function that allows for easy On/Off for this setting How to use: Follow the sun - do not turn off the red light filter until you have consumed true natural red light from the sun in the AM for at least 10-15 mins. I usually wait well into the morning and after my morning outdoor walk before I triple click back to “normal view” Once dusk hits, so too should your red light filter return. So in the winter, that’s like 6p where I live… Ideally, you are not consuming screens at least 2 hours before bed for max circadian support. But if you must, make sure you are at least using this one quick easy technique. Our modern tech lives lead to an absolute decimation of our circadian rhythms, which subsequently leads to all sorts of detrimental impacts like low T, insulin resistance, fat gain, and thyroid dysfunction, amongst many others.
