How teens deal with stress may affect their blood pressure, immune system

Most teens get stressed out by their families from time to time, but whether they bottle those emotions up or put a positive spin on things may affect certain processes in the body, including blood pressure and how immune cells respond to bacterial invaders, according to Penn State researchers.

The researchers explored whether the strategies adolescents used to deal with chronic family stress affected various metabolic and immune processes in the body. Strategies could include cognitive reappraisal — trying to think of the stressor in a more positive way — and suppression, or inhibiting the expression of emotions in reaction to a stressor.

The team found that when faced with greater chronic family stress, teens who used cognitive reappraisal had better metabolic measures, like blood pressure and waist-to-hip ratio. Teens who were more likely to use suppression tended to have more inflammation when their immune cells were exposed to a bacterial stimulus in the lab, even in the presence of anti-inflammatory signals.

It’s not just for kids — even adults appear to benefit from a regular bedtime

DURHAM, N.C. — Sufficient sleep has been proven to help keep the body healthy and the mind sharp. But it’s not just an issue of logging at least seven hours of Z’s.

A new study on sleep patterns suggests that a regular bedtime and wake time are just as important for heart and metabolic health among older adults.

In a study of 1,978 older adults publishing Sept. 21 in the journalĀ Scientific Reports, researchers at Duke Health and the Duke Clinical Research Institute found people with irregular sleep patterns weighed more, had higher blood sugar, higher blood pressure, and a higher projected risk of having a heart attack or stroke within 10 years than those who slept and woke at the same times every day.

Irregular sleepers were also more likely to report depression and stress than regular sleepers, both of which are tied to heart health.
