For the full deep dive with all the studies and protocols, listen to a full podcast I recently joined and read the full protocols here: https://brandonluumd.substack....

HIIT: Metabolic Protection Just 10 intervals of 60s at 90% max effort protects you from sleep restriction metabolic damage. Without exercise, glucose tolerance worsens +22% and mitochondrial function drops -18%. HIIT completely prevented these metabolic impairments. /3

Moderate Cardio for Instant Cognitive Rescue 20 minutes of cycling at 60% VO₂max after an all-nighter restores reaction time from 14% impaired to just 7% below baseline. It works by boosting cerebral blood flow and activating attention circuits. /4

Creatine: Single Dose Strategy 0.35 g/kg (~25-30g) taken 4h before peak performance rapidly increases brain ATP and phosphocreatine. In some cases, sleep-deprived subjects on creatine even outperformed their rested baseline on cognitive tasks. /5

Creatine: Loading Protocol 20g/day × 7 days before sleep deprivation preserves reaction time and executive function through 24-36h of wakefulness. The usual 3-5g maintenance dose is unknown for brain health: 10g/day may be optimal for cognition. /6

Caffeine Meta-analysis of 45 studies: 340mg caffeine significantly improves reaction time, response time, and accuracy during sleep deprivation. Larger doses up to 600mg provide greater benefits for attention and driving safety. /7

Bright Light 30 min of 10,000 lux light at 5 AM improves attention by 200ms and preserves working memory by 25% after an all-nighter. Even 2,000 lux blue-enriched glasses work. The effect peaks within 2h via melanopsin pathways. /8

Driving Safety 45 min of 5,600 lux bright light after a night shift eliminated all driving crashes in a simulator study. 26% crashed in dim light; zero crashed with bright light exposure despite not feeling more alert subjectively. You still shouldn't drive when severely sleep

Chocolate A single dose of flavanol-rich dark chocolate two hours before tasks reversed some of the negative cardiovascular changes from sleep deprivation and preserved working memory performance, particularly in women. /10

Green Tea In mice, 3 weeks of green tea extract (200 mg/kg/day) or EGCG (50 mg/kg/day) completely prevented memory impairment from 6-hour sleep deprivation by restoring antioxidant defenses in the hippocampus. /11

Nicotine? Rats that are sleep deprived for 48 hours make significantly more error on the radial-arm water maze. However, nicotine administration completely reverses the number of mistakes back to baseline. This still needs further study in humans. /12

Overall, sleep deprivation impairs you to the level of alcohol intoxication and causes significant metabolic harm, but strategic interventions (exercise, creatine, caffeine, bright light) can preserve performance when sleep isn't an option https://x.com/DavidPuder/statu...

@BrandonLuuMD If only the team at @hubermanlab took the time like you do to break protocols down into enjoyable, EASY to read, digestible, and quickly referenced, actionable bits. Thank you 🙏🏻🙏🏻🙏🏻

@BrandonLuuMD @readwise save thread

@BrandonLuuMD If you do HIIT in the day time it anyways help you sleep better at night

@BrandonLuuMD Super interesting! Thats why I believe sleep should be the foundation for any optimization programs.

@BrandonLuuMD Get good sleep the next night

@BrandonLuuMD How about cold showers and (non-HIIT) compound lifts?

@BrandonLuuMD You had me at ‘sleep isn’t an option, but HIIT is’

@BrandonLuuMD This whole coffee hype definitely has its dark side one that very few people talk about, including @hubermanlab himself and I'm always wondering why nobody talks about it as there's plenty of studies to support this. Coffee and energy drinks that contain caffeine, when consumed

@BrandonLuuMD Sleep debt’s real but biohacks are the interest payments 😴

@BrandonLuuMD Wild how missing sleep can hit memory, glucose control, and even mitochondria this hard. What’s encouraging is that tools like HIIT, creatine, caffeine, and bright light aren’t just hacks, they work by supporting energy metabolism and circadian alignment.

@BrandonLuuMD @grok how are they defining sleep deprivation?

@BrandonLuuMD @threadreaderapp unrroll

@BrandonLuuMD Sleep loss takes a toll on memory, glucose control, and energy metabolism, all of which suffer. Thankfully, smart hacks like HIIT, caffeine, creatine, and bright light can help buffer the impact when rest isn’t possible.

@BrandonLuuMD A significant reduction in episodic memory formation! You're losing almost half of what you learn. Exposure to bright light in the morning suppresses melatonin and tells your internal clock that it is daytime, increasing alertness even after sleeping badly.

@BrandonLuuMD Now tell people there cause of all of those. It's magnesium. The pancreas needs magnesium to make insulin. "Dietary Magnesium Intake Affects the Vitamin D Effects on HOMA-β and Risk of Pancreatic β-Cell Dysfunction: A Cross-Sectional Study" https://www.frontiersin.org/ar...
