To optimize health, he recommends the 'physiological sigh' breathing technique (two inhalations followed by one long exhalation) to calm the nervous system, morning sunlight exposure for the circadian rhythm, and a daily intake of 5g of creatine (10g in cases of sleep deprivation).

The 'physiological sigh' is supported by a Stanford University study (RCT, 2023) showing that it reduces anxiety and improves mood more effectively than other breathing techniques. Sunlight exposure is a practice validated by an extensive body of literature (observational studies and reviews) confirming its crucial role in the regulation of cortisol and melatonin via the suprachiasmatic nucleus. Creatine is one of the most studied supplements (meta-analyses): its benefit for physical and cognitive performance is robust. However, the claim that doubling the dose to 10g during sleep deprivation provides direct support for brain function is an interesting extrapolation but still lacks robust clinical evidence in humans. The advice is generally based on well-understood biological mechanisms, although the specific application for sleep deprivation is more speculative.
