Natural cycles of light and dark are needed for ideal wellbeing. Artificial light at night disrupts this rhythm, but does it lead to ill health? Read more about the surprisingly complicated relationship between light at night and human health, and what we still need to learn to find the optimal balance between them.
Plastic food packaging contains harmful endocrine disrupting chemicals, new study confirms.
36 #foodPackaging materials tested from 5 countries: 33 of them (92%) contained chemicals that interfere with hormone receptors crucial to #humanHealth.
🤔 "The International Commission on Non-Ionizing Radiation Protection (ICNIRP) has identified a lack of consensus among public health officials regarding whether short wavelength light (SWL) from artificial sources disrupts circadian rhythm, and if so, whether SWL-disrupted circadian rhythm is associated with adverse health outcomes."
"We found that exposure to light at night was associated with higher odds of allergic diseases, with the strongest association observed for ALAN exposure, followed by evening #chronotype and exposure to night shift work."
"This paper discusses ... some policy insights for reducing circadian disruption include regulating shift work, updating public lighting, and incentivizing circadian-based technologies."

Although the precision of the estimates was affected by the limited sample size and the study design did not allow us to exclude the presence of residual confounding, these results suggest a possible role of LAN in the etiology of #dementia particularly of its late-onset form.
