Deadlines Don’t Cut It: Stress Levels Remain Unchanged, Regardless of Timelines

Researchers have discovered that deadlines may not be as stressful as previously believed. The study found that high sympathetic activation, which indicates how much people are "on the tips of their toes" and leads to stress, remains about the same with or without deadlines. The study also discovered that factors such as extensive smartphone use and prolific reading and writing can exacerbate sympathetic activation.

Stress Rapidly Increases Biological Age, but Recovery Turns Back the Clock

Stress can cause rapid and transient increases in biological age, which can be reversed upon recovery, according to a new study. Using DNA methylation clocks, researchers found that stress triggers short-term fluctuations in biological age in humans and mice. The findings challenge the idea that biological age has a unidirectional upward trajectory over the life course, and highlights the importance of reducing biological age to improve longevity.

New Discovery Reveals Sex-Specific Causes of Depression Triggered by Stress Hormones Dysfunction

Men are more likely to have a dysregulated HPA axis that is associated with depressive symptoms, while women have higher levels of binding proteins for stress hormones that may prevent dysregulation of the HPA axis. The findings shed new light on how stress hormones impact dopamine transmission and how this impacts depression on a sex-specific basis.

Discovery in Zebrafish May Yield Better Understanding of a Range of Mental Health Disorders Related to Stress and Anxiety

Deficiencies in DSCAML1 disrupt normal brain development and increase baseline levels of cortisol, making the hormone less able to function correctly during periods of stress. The findings shed new light on programmed cell death in the developing brain and could lead to new treatments for mental health disorders including stress and anxiety.
