Marie Sullivan says that she knew something "wasn't quite right" during a doctor visit five years ago.
"I thought I might be anemic, but the results of my annual physical were fine," she recalled. "All my numbers were in the normal range. The blood work turned up nothing. I said to my doctor, 'Are you sure? What's wrong with me?' "
Her doctor blamed her age, but Sullivan, 55 at the time, wasn't buying it. "I'm not that old," she said. "I know you slow down as you age, but I'm physically exhausted all the time. And I know I'm not the only person who feels this way."
Lassitude. Weariness. Fatigue. Whichever term you prefer, recurring tiredness seems to be the new normal for a growing number of people, regardless of their age or background. Typical causes include illnesses such as anemia, depression, hypothyroidism, diabetes and heart disease.
But increasingly, medical professionals are looking at a new source of the problem: the increasing overuse of technology and its implications on our mental well-being.
Yes, Facebook, Twitter and Instagram can wear you out, said Patricia Bratt, a therapist and psychoanalyst with offices in New York City and Livingston, N.J.
"Social media can run the gamut from being fabulously uplifting to being totally depressing and exhausting," said Bratt, who is also the director of trauma and resilience studies at the Livingston-based Academy of Clinical and Applied Psychoanalysis. "And this applies to all ages."
Bratt works with young adults who check their social media constantly and at all hours of the day and night. They all complain about being tired.
