The claim
A newspaper clip suggests that sudden waking at night can cause death and recommends the three-and-a-half-minute method as a preventive measure.
Original review summary
The review found no scientific evidence that suddenly waking at night causes death. It says the body regulates blood pressure and circulation when moving from sleep to standing, so the three-and-a-half-minute method is unnecessary.[S1]
Additional context
Standing can cause a temporary blood-pressure drop known as orthostatic hypotension, which may lead to dizziness or fainting; the review says sitting up slowly for around 30 seconds before standing can help prevent these symptoms. [S1]
