But this combination has an unhealthy downside. According to Sydney scientists, stress combined with calorie-dense comfort food creates changes in the brain that drive more eating, boost cravings for sweet, highly palatable food...

CHINESE ACADEMY OF SCIENCES HEADQUARTERS Clinical studies have found that bone mineral density in patients with anxiety or depression is lower than in ordinary people. The brain, commander of the body, receives and processes external signals, and then sends instructions to peripheral bones. But how does anxiety induce a decline in bone mineral density? Researchers...
Stress-related conditions such as adjustment disorder and clinical burnout can be effectively treated with a 12-week cognitive-behavioral programme, both when delivered as a face-to-face treatment and when delivered via the internet, according to a new doctoral thesis from Karolinska Institutet.

But constant stress can affect overall well-being and may even impact heart health. When stress is short-lived, it can help with performance in meeting a major deadline, interviewing...
Micro inflammation developed at specific sites in the brain (top panel). Pathological analysis of the stomach showed damage to tissues in the stomach (bottom right) compared to mice not under stressful conditions (bottom left). New research reveals the mechanisms behind the effects of chronic stress and tiny inflammations in the brain on fatal gut failure....
