Stress

When someone is suffering from post-traumatic stress disorder, psychiatrists will sometimes have them place themselves in stress-triggering environments. An experimental wearable system has now been shown to make such treatment much more effective.

While most of us have a pretty good sense of when we're getting too stressed, people with certain mental health issues may benefit from being made aware of the situation. A new palm-worn electronic tattoo could help in that regard.

Striking new research proposes taking a common anti-inflammatory drug soon after experiencing a traumatic event could help people forget upsetting memories and reduce their risk of developing post-traumatic stress disorder (PTSD).

A new study has shed light on how an experimental drug can reverse some of the damage associated with traumatic brain injury. The findings lay the groundwork for a drug that could prevent the cognitive deficits that follow on from concussion.

Having been domesticated many thousands of years ago, dogs have evolved to become highly attuned to human behavior, but a study from scientists at Queen's University Belfast has taken this concept into new terrain.

We all know a good, long walk in nature can be relaxing, but a landmark new study offers some of the first causal evidence to show exactly how a one-hour walk in the forest reduces activity in brain areas responsible for processing stress.

When experiencing anxiety, many people may feel the need to hug a squishy object such as a cushion. According to a new study, the act of doing so could actually help reduce feelings of anxiety – especially if the cushion "breathes."

It's important for people with conditions such as depression and anxiety to know when they're becoming stressed, so they can initiate coping strategies. An experimental smartwatch could someday warn them, by detecting a stress hormone in their sweat.

A new study has highlighted the gut-brain link between social behavior and gut microbes in mice, showing how a lack of certain gut bacteria can increase levels of a hormone that activates a part of the brain that contributes to antisocial activities.

When a baby is born premature, it's vitally important that the infant's still-developing brain receive enough oxygen. A new medical device could help, by mimicking the heartbeat and breathing of a parent.

Scientists have developed a patch designed to continuously monitor stress levels over the course of the day, which they hope will make it easier to spot signs of stress-related disease caused by disruptions to natural hormonal cycles.

Dormant tumor cells can sit quietly for years but exactly what reactivates these sleeping cancer cells is unknown. A new study is offering a novel hypothesis, suggesting stress hormones can trigger a chain of events that reawaken these dormant cells.
