The most extreme contemporary claim found. Her wording describes severe restriction in office and an explicit wish for more sleep.

The figure fits his cultivated image of extraordinary vitality, while the accessible source trail stops at a tertiary summary.

Historical biographies repeat the three-hour figure. Another account records afternoon sleep, raising the likely daily total.

A direct and explicit statement. No public objective measurement establishes that this duration reflects his biological sleep need.

A contemporary report tied to bombing, illness and crisis command. It does not establish a lifelong routine.

Accounts describe flexible sleep, short bouts and recovery after campaigns. A precise daily average cannot be reconstructed.

One of the strongest historical claims, stated directly and repeatedly by Thatcher. Her belief that reduced sleep could be trained differs from the modern definition of natural short sleep.

The account describes the shared rhythm of the president and his two closest Élysée aides. The number comes from his entourage.

Officers who worked with him described the same Spartan routine. The testimony is close to the subject but remains observational.

Ancient sources describe endurance and rapid travel. The three-hour figure does not appear in the checked ancient testimony.

Ronny Jackson explicitly called it a guess based on proximity and said he had not asked the question. The number is well attributed and weakly measured.

Insomnia, an irregular schedule and sedatives produce a medically and circadianly chaotic case. The phrase “Mao slept little” loses the ten-to-twelve-hour episodes.
