WHAT IT’S REALLY ABOUT
Deep Sleep, Regularity, Creatine and Omega-3s: Protecting Your Brain Health
- Louisa Nicola says deep stage three sleep activates the glymphatic system, in which cerebrospinal fluid washes out debris such as amyloid beta and other toxins.
- She cites a study in which healthy men sleeping about six hours a night for one week showed epigenetic changes in around 3% of their genes, which she says raised tumor-related genes and lowered immunity genes.
- She argues that sleep quantity (at least seven and a half hours) and regularity (sticking to a consistent schedule about 80% of the time) matter most, and she treats sleep trackers as useful for trends rather than accurate staging.
- For a racing mind at bedtime she suggests journaling, setting personal standards and routines, and supplements such as ashwagandha, turmeric and GABA, with a caveat to consult a healthcare provider.
- She recommends creatine monohydrate and omega-3s for everyone without needing a blood panel, and suggests an omega-3 index test to check individual levels.
IDEAS WORTH REMEMBERING
5 ideasDeep sleep works like a brain washing machine
Nicola says that during stage three sleep glial cells shrink, letting cerebrospinal fluid flush out amyloid beta, environmental toxins and mycotoxins.
Six hours of sleep may count as deprivation
She describes a study in which one week at about six hours a night changed around 711 genes, roughly 3% of the genome, and Rangan Chatterjee notes many people are happy with six hours.
Regularity may matter more than anything else
Nicola says research now points to consistent sleep and wake times as most important, and she aims to stay within 10 to 20% of her usual schedule rather than being perfect.
Trackers are best for trends, not sleep stages
Nicola says her Oura Ring isn't very accurate compared with a polysomnography sleep study but is useful for heart rate variability and time in bed, and Chatterjee agrees trends are useful if people don't become obsessed.
Calm a busy mind with behavior first
She suggests writing down everything on your mind before bed and setting standards, such as going offline and dimming lights at a fixed time, with supplements as an additional option.

It's creatine, um, creatine monohydrate. It helps with cell energy metabolism, and we used to think of creatine back in the day of this bodybuilding drug, but creatine is so much more than that. It is the safest supplement on the market.
