Bryan Johnson's 4-Hour Sleep Rule
Tech entrepreneur Bryan Johnson's "4-hour rule" for better sleep involves not eating four hours before bedtime and avoiding food after noon, claiming to improve sleep quality by 30%. The biohacking routine represents the cutting edge of sleep optimization, though Johnson's extreme approach may not be suitable for everyone. His method is part of a broader biohacking trend detailed in the newly released ebook *The Optimized Human: A beginner's guide to biohacking*, which covers practical steps to upgrade sleep, nutrition, exercise, and mindset.
- Bryan Johnson's comprehensive anti-aging regimen, known as Project Blueprint, costs over $2 million annually and involves a team of more than 30 doctors and health experts monitoring his bodily functions. The project's goal is to reverse the aging process in all of his organs. - His strict daily diet is entirely plant-based (with the exception of collagen peptides) and consists of precisely 2,250 calories consumed before 11 a.m., followed by an 18-hour fast. Johnson's routine also includes taking more than 100 supplements per day. - Beyond diet, Johnson's routine includes waking at 4:30 a.m., hour-long workouts, red light therapy, and wearing a cap that shoots red light into his scalp to stimulate hair growth. He has also undergone more experimental procedures like gene therapy and previously received blood plasma transfusions from his son, a practice he has since discontinued. - Johnson claims his biological age has been significantly reversed, stating he possesses the heart of a 37-year-old, the skin of a 28-year-old, and the lung capacity of an 18-year-old. His team tracks over 100 of his biomarkers to measure progress. - Johnson has begun to commercialize his methods, recently launching an exclusive program called "Immortals" that offers his complete protocol for a fee of $1 million per year, with only three spots initially available. - The practice of "biohacking" encompasses a wide spectrum of activities, from widely accepted practices like intermittent fasting and meditation to more experimental and controversial methods like nootropics ("smart drugs") and DIY gene editing. - While some biohacking techniques are supported by scientific evidence, many claims within the community lack robust research. The FDA has issued warnings against certain practices, such as receiving plasma from young donors, stating they have no proven clinical benefit and can be unsafe.
