They found Vitamin-D supplementation significantly reduced pain and intensity of dysmenorrhea. Vitamin D reduced pros-taglandin levels and inflammation. Since Vitamin-D receptors are found in the ova-ries, uterus, placenta, and pituitary gland, Vitamin D could suppress the expression ofinflammation-inducedmarkersand contractile-associated factors in the uter-ine myometrial smooth muscle cells by interacting with these receptors.Lin K, Huang K, Lin M, et al., Vitamin D Supplementation for Patients with Dysmenorrhoea: A Meta-Analysis with Trial Sequential Analysis of Randomised Controlled Tri-als, Nutrients, 2024, 16(7): 1089, athttps://doi.org/10.3390/nu16071089.40 Hz Sensory Gammathe Picower Institute for Learning and Mem-Rhythm Stimulation Clearsory of MIT revealed a key mechanism that Amyloid in Alzheimer Micemay contribute to these beneficial effects: Studies at MIT and elsewhere are pro- clearance of amyloid proteins, a hallmark ducing mounting evidence that light flicker- of AD pathology, via the brains glymphatic system, a recently discovered plumbingTeens Benefit from Forest ing and sound clicking at the gamma brainnetwork parallel to the brains blood vessels.

The study was the first ever to collect on-site, re-al-time survey data from adolescents about their emotional responses to various urban environments like a transit hub, residential streets, trails, parks, and waterways. After standing and looking at an urban lake for just two or three minutes, youth scores on a validated anxiousness scale decreased by nine per cent. On the other hand, their anx-iousness scores were 13 percent higher when standing in a busy downtown location for the same length of time.Buttazzoni A, Minaker L, Associations between real-time, self-reported adolescent mental health and urban and archi-tectural design concepts, Cities & Health, 11 Dec 2023, at https://doi.org/10.1080/23748834.2023.2286741.22 H ealtHF reedomN ews /s priNg2024'
