More on the Cognitive Benefits of Moderate Exercise

“There is over­whelm­ing evid­ence that exer­cise pro­duces large cog­nit­ive gains and helps fight demen­tia”, says the Har­vard Uni­ver­sity psy­cho­lo­gist John Ratey, author of the 2008 book on the sub­ject, Spark.

While Ratey pro­pounds the “very clear” link between exer­cise and men­tal acu­ity, say­ing that even mod­er­ate exer­cise pushes back cog­nit­ive decline by “any­where from 10 to 15 years”, the Nation­al Insti­tutes of Health are more cau­tious:

Look­ing at redu­cing the risk of “cog­nit­ive decline in older adults,” [the NIH] wrote: “Pre­lim­in­ary evid­ence sug­gests a bene­fi­cial asso­ci­ation of phys­ic­al activ­ity and a range of leis­ure activ­it­ies (e.g., club mem­ber­ship, reli­gious ser­vices, paint­ing, garden­ing) with the pre­ser­va­tion of cog­nit­ive func­tion.” A few small stud­ies showed that “increased phys­ic­al activ­ity may help main­tain or improve cog­nit­ive func­tion in nor­mal adults”.

I’ve writ­ten before about the extens­ive cog­nit­ive bene­fits of exer­cise, but as Noah Gray (via) says, “it nev­er hurts to rein­force the mes­sage”.
