Winston Churchill, the British Prime Minister during World War II who led the strong fight against Germany to secure the final victory of the Allies, and at the same time a historian and writer who won the Nobel Prize in Literature. How was he able to maintain his peak mental alertness without getting exhausted under the grueling state duties of over 18 hours a day? The secret lay in a very unique and firm ‘nap routine’ he had every afternoon. Every afternoon between 2:00 and 2:30 PM, Churchill stopped all state reports and went to his bedroom, undressed completely, and took a deep nap for 1 to 2 hours. This schedule was strictly protected even during the war. Churchill boasted that thanks to his nap, he was able to split the day into ‘a day with two independent mornings.’ Today, BuildSelf shares the neuroscientific truth behind Churchill’s nap and the Power Nap practice for modern people to completely reset their fatigue.
Historical & Academic Evidence
This content is based on Winston Churchill's 'The Second World War' & NASA Astronaut Power Nap Study.
1. The Science of Napping: Clearing the Brain’s Waste
While humans are awake and active, a fatigue substance called adenosine constantly accumulates between brain cells. When adenosine accumulates above a certain level, the brain’s cognitive ability drops sharply and information processing speed slows down. A short nap in the afternoon quickly decomposes this adenosine, clearing the fatigue of brain cells. In particular, a short nap of about 20 minutes is timed to wake up before the brain falls into deep sleep (NREM stage 3), so it restores high alertness and attention without ‘sleep inertia’ (the groggy state after waking up). The ‘two days’ Churchill mentioned is not just a feeling, but a scientific fact that the brain actually met morning alertness twice.
2. 3-Step Practical Routine for Modern Professionals
Set a timer between 1 PM and 2 PM
Between 1 PM and 2 PM, when drowsiness and fatigue peak after lunch, switch your smartphone to do-not-disturb mode. Set the alarm for exactly 20 minutes to prevent sleep inertia. It is best to finish before 3 PM so it does not interfere with nighttime sleep.
Block visual information and close your eyes
Lean back in a comfortable chair or lie in bed, and use an eye mask or earplugs to minimize external stimuli. Even if you cannot fall into a deep sleep, just closing your eyes and blocking visual information puts the visual cortex into rest mode, greatly reducing cognitive fatigue.
Wake up immediately when the alarm rings
When the 20-minute alarm rings, shake off the temptation to lie down longer and get up immediately. Drink a glass of cold water to awaken your body's senses and stretch lightly. Resume your afternoon work feeling your brain running fresh again like morning.
3. A brain-scientific word for a successful routine
Sitting blankly at your desk in the afternoon with low concentration greatly reduces productivity. Instead of forcing yourself through that inefficiency, recharge your focus with a 20-minute power nap like Churchill. Your brain will be optimized, allowing you to immerse yourself in the rest of the day with a fresh and clear mind.
