Reading on a Smartphone, and Sighing

If you are reading this on a smartphone, please monitor your sighing activity. As you read, and as you sigh, consider the details presented in the following study:

Reading on a Smartphone Affects Sigh Generation, Brain Activity, and Comprehension,” Motoyasu Honma, Yuri Masaoka, Natsuko Iizuka, Sayaka Wada, Sawa Kamimura, Akira Yoshikawa, Rika Moriya, Shotaro Kamijo, and Masahiko Izumizaki, Scientific Reports, vol. 12, no. 1589, 2022. (Thanks to Tony Tweedale for bringing this to our attention.) The authors, at Showa University School of Medicine, Japan, explain:

We found that, compared to reading on a paper medium, reading on a smartphone elicits fewer sighs, promotes brain overactivity in the prefrontal cortex, and results in reduced comprehension. Furthermore, reading on a smartphone affected sigh frequency but not normal breathing.
