The video references real cases of unusual autonomic control, but the exact timings and “you could learn this from screen time” framing are not supported.
Claim-by-claim breakdown
Accurate (78% confidence): A yogi in the 1970s reportedly stopped his heartbeat in front of doctors while connected to monitoring equipment. A 1962 New York Times report described yogis interrupting heart activity for seconds in a medical study, and a 2024 NIH/PMC review discusses Swami Rama and other yogis showing pauses or major slowing of heartbeat in lab demonstrations.
Unsupported (43% confidence): With enough practice, a person could isolate a single muscle and make one hand warm while the other stays cold. There is evidence that meditation and biofeedback can affect body temperature and that people can learn to control some physiological responses, but I did not find a reliable source confirming this exact skill as stated.
Misleading (64% confidence): A person can slow their pulse almost to nothing on command after enough training. Medical and academic sources support that meditation can lower heart rate and blood pressure, but not that people can routinely reduce pulse to near zero at will.
False (86% confidence): The video implies that spending six to ten hours a day on screens could realistically teach these kinds of muscle-control feats. No credible evidence supports a specific screen-time threshold for learning autonomic control feats; such abilities, where documented at all, come from specialized training and rare demonstrations, not passive screen use.
