Doctor Iza shares an experience consistent with current scientific literature. The positive impact of aerobic exercise on cardiovascular health is widely supported by meta-analyses (e.g., Circulation, RCTs), confirming the benefit to the heart. The effect of 'mental clarity' and stress reduction is documented in observational studies and systematic reviews highlighting the release of endocannabinoids and the reduction of cortisol. Perceived improvement in sleep is also validated by meta-analyses (e.g., Sleep Medicine Reviews) showing that physical activity helps regulate the circadian cycle. The increase in self-confidence and productivity through exercise is a recognized phenomenon in sports psychology, although often measured by self-assessments. While some aspects such as increased creativity are more complex to isolate rigorously, they remain frequently reported effects. Overall, the statement is very solid and is based on well-established physiological mechanisms.

What the graded evidence says

Evidence
B

Linked to, not proven to cause.

Effect
all-cause mortality by combination of aerobic + muscle-strengthening activity — 1 h/week aerobic HR 0.85 and levelling to ~0.73 at 3 h/week; adding muscle-strengthening 1-2x/week conferred further risk reduction; lowest mortality in those meeting both guidelines
Measured on
US adults (416,420 and 500,705 in two national cohorts)

What’s uncertain

These are associations from observational cohorts, not proof of cause; healthier or more motivated people may do more of both. The specific percentages sometimes quoted for one activity vs another come from particular studies and shouldn't be treated as fixed.
