From cardiovascular disease and obesity to a weakened immune system, the side effects of stress can be life-altering. But there may be a way to prevent those outcomes.
Raising triplets Hays, Presley, and Millie is challenging for Caitlin and Chris Nichols of Lawrenceville, Georgia. Born prematurely, the children have long-term health problems. Caregivers of chronically ill children face health difficulties themselves: Telomeres—protective caps at the ends of chromosomes—are shorter than expected, a possible sign of stress-related aging.
So far, one of the major realizations among scientists is that stress harms all of us in different and powerful ways. But is there any way to avoid it—or at least recover more quickly? Some promising avenues of research offer hope for the future. In an Amsterdam lab, a mouse searches for the hole that allows it to escape a maze. Researchers stressed nursing females by limiting nesting material, to see the effects on their pups. Once grown, the mice were tested in the maze. In contrast to mice with easier infancies, the mice reared by stressed mothers did poorly, taking longer to remember where the escape hole was.
Monochromatic brain scan of a young girl highlights two sections in bright orange where emotional stimuli indicates signs of child maltreatment. Research into individuals who suffered abuse as children shows that their brains react strongly to emotional stimuli.
Researchers then administered the flu and pneumonia vaccines to individuals responsible for a spouse with dementia. Unlike medical students taking exams, who were likely stressed only in the short term, these people were experiencing unrelenting stress. When tested at set periods after inoculation, they—they couldn’t maintain their protective response.
