In a 2008 study, Linda Stone discovered that many people held their breath or altered their breathing patterns while checking their email, coining the term “email apnea.” This phenomenon has since expanded to include all tasks done in front of a screen, now referred to as “screen apnea.” James Nestor, in his book “Breath,” explains that our increased use of screens has likely worsened this issue. Screen apnea is a manifestation of our body’s stress response, causing physiological changes such as shallow breathing and a slowing of heart rate. The lack of movement associated with prolonged screen time may also contribute to screen apnea. To improve breathing habits, experts suggest setting up breath reminders, using larger screens, and engaging in activities that promote relaxation and physical activity during breaks.
