What holds up

Para SF selection and service are widely described as highly demanding, and Major Rishabh Singh Sambyal’s rank is recorded in an official Gazette notice.

What does not

The visible claim says 90 days without sleep. Evidence on total sleep deprivation shows serious impairment, including hallucinations and disordered thinking, emerging after only several days; the reviewed human studies extended to 264 hours, or 11 days, not 90 days.

Why it matters

Material. Calling a 90-day training or probation period “90 days without sleep” turns a strenuous but plausible training claim into an extreme physiological claim that would substantially change how viewers understand Para SF training.

Why Clear says this

The claim is a literal, testable assertion about continuous sleep deprivation. Medical evidence directly conflicts with its implication that people can function through 90 consecutive sleepless days. A reported 90-day probation period, if applicable, would not establish 90 days awake.

Evidence

  • A peer-reviewed systematic review of 21 sleep-deprivation studies found escalating perceptual disturbances and psychosis-like symptoms with sustained wakefulness, with studies lasting from 24 to 264 hours (11 days).
  • A peer-reviewed medical review describes 264 hours as the longest voluntary period without sleep and reports marked impairment at that duration.
  • An official Gazette record lists Rishabh Singh Sambyal as a substantive Major effective June 9, 2024; it does not substantiate the 90-days-without-sleep assertion.
  • Open-source descriptions commonly refer to a 90-day Para SF probation period, but no authoritative public source located supports the claim that it requires continuous wakefulness for all 90 days.
