👉 The term "canal human experiments" can be a misleading or metaphorical reference and is not a widely recognized historical practice, but it could hypothetically refer to secretive or illicit medical or psychological studies conducted on humans that took place along canals or waterways, possibly exploiting the conditions such as stagnant water or confined spaces. Historically, these kinds of clandestine experiments were often part of broader efforts to understand human physiology under extreme conditions, but their exact nature and extent remain unclear.
