Morning blue light treatment improves sleep complaints, symptom severity, and retention of fear extinction memory in post-traumatic stress disorder
Disrupted sleep is a major feature in numerous clinical disorders and is related to decrements in affective memory processing. The prevalence of sleep disruption in post-traumatic stress disorder (PTSD) is suggested to be a key feature that exacerbates the impaired ability to recall extinction memories during experimental fear conditioning. We hypothesized that an intervention employing… Continue reading Morning blue light treatment improves sleep complaints, symptom severity, and retention of fear extinction memory in post-traumatic stress disorder

Role of housing in blood pressure control: a review of evidence from the Smart Wellness Housing survey in Japan
Current countermeasures for preventing hypertension emphasize only improvements to lifestyle. Recently, improving life environment has attracted attention, in parallel with publication of the WHO Housing and health guidelines. We quantitatively evaluated the relationship between housing thermal environment and blood pressure (BP) in a real-world setting. We conducted a nationwide, prospective intervention study—the Smart Wellness Housing… Continue reading Role of housing in blood pressure control: a review of evidence from the Smart Wellness Housing survey in Japan
How nature nurtures: Amygdala activity decreases as the result of a one-hour walk in nature
Since living in cities is associated with an increased risk for mental disorders such as anxiety disorders, depression, and schizophrenia, it is essential to understand how exposure to urban and natural environments affects mental health and the brain. It has been shown that the amygdala is more activated during a stress task in urban compared… Continue reading How nature nurtures: Amygdala activity decreases as the result of a one-hour walk in nature
Titanium dioxide particles frequently present in face masks intended for general use require regulatory control
Although titanium dioxide (TiO2) is a suspected human carcinogen when inhaled, fiber-grade TiO2 (nano)particles were demonstrated in synthetic textile fibers of face masks intended for the general public. STEM-EDX analysis on sections of a variety of single use and reusable face masks visualized agglomerated near-spherical TiO2 particles in non-woven fabrics, polyester, polyamide and bi-component fibers. Median sizes… Continue reading Titanium dioxide particles frequently present in face masks intended for general use require regulatory control
The hidden link between circadian entropy and mental health disorders
The high overlapping nature of various features across multiple mental health disorders suggests the existence of common psychopathology factor(s) (p-factors) that mediate similar phenotypic presentations across distinct but relatable disorders. In this perspective, we argue that circadian rhythm disruption (CRD) is a common underlying p-factor that bridges across mental health disorders within their age and… Continue reading The hidden link between circadian entropy and mental health disorders
Environmental impassivity: Blunted emotionality undermines concern for the environment
The average American believes in climate change, worries about it, and supports related policy, but there are still considerable differences—across individuals and with political ideology—that limit the ability to foster change. Researchers and practitioners often increase concern and action for others through feelings of empathy, which also increases pro-environmentalism. However, some people appear less emotionally… Continue reading Environmental impassivity: Blunted emotionality undermines concern for the environment
