What portion of all adults in the U.S. have said that worry and stress related to Covid-19 has harmed their mental health badly enough to create physical effects?
A scientific nationally representative survey conducted by the Kaiser Family Foundation in April 2020 found that 56% of U.S. adults "report that worry and stress related to" Covid-19 "is affecting their mental health and wellbeing in various ways," such as "trouble sleeping, "poor appetite or over-eating," "frequent headaches or stomachaches," "difficulty controlling their temper," "increasing their alcohol or drug use," and "worsening chronic conditions like diabetes or high blood pressure." Worry and stress are among the most debilitating and deadly of all health hazards, and they can cause early death for many years after they subside. A May 2020 study by Just Facts found that anxiety from reactions to Covid-19 will destroy at least seven times more years of life than can possibly be saved by lockdowns. These results have since been corroborated by a study published by the journal European Psychiatry.
