https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6612475/ is a review of Britton's research discussed in the article. It presents several points of evidence with a coherent argument for why meditation brings benefits while an excessive level of meditation may cause adverse effects.

It's interesting that anyone even had to specify that excessive meditation could cause harm. Isn't the whole point of Buddhism to follow the "middle way"?

The problem with "excessive X causes harm" is that it is tautologically true. The real question is the quantitative level where it starts doing more harm than good. Nobody knows, but it's easy to say after the fact that something is "excessive".
