“Eating breakfast is not necessary for human health.”
Breakfast is not universally required to maintain health. Randomized evidence does not show consistent broad harm from skipping it, while adverse associations found in observational studies may partly reflect overall diet, lifestyle, and socioeconomic differences. Individual nutritional needs and some cardiometabolic markers can still make breakfast beneficial for particular people.
“A single night of only 3 to 4 hours of sleep causes detrimental effects on human health.”
The claim is mostly true. Peer-reviewed research confirms that a single night of only 3–4 hours of sleep causes measurable detrimental effects, including impaired cognitive performance, increased sleepiness, mood disturbances, elevated stress hormones, and reduced physical performance. However, these effects are generally acute and reversible with recovery sleep — not equivalent to the chronic disease risks (cardiovascular, metabolic) associated with sustained sleep deprivation. Individual vulnerability also varies significantly.
