Read moreThe timing of when a person sleeps—not just how long—plays a vital role in mental health, influencing mood, cognitive function, and overall well-being. A recent study found that misalignment between bedtime and natural sleep preferences can increase the risk of mental health disorders like depression and anxiety. Researchers identified the chronotype—whether they were morning or evening types—of nearly 74,000 middle-aged and older adults enrolled in the UK Biobank. They tracked sleep patterns using accelerometry and evaluated their sleep and chronotype alignment. They assessed mental health ou... sleep depression mental health anxiety
Read moreRegular exercise has long been known to protect cognitive functions such as attention, memory, and processing speed as we age. A recent study found that exercise may also improve older adults' language comprehension by enhancing cardiorespiratory fitness—the body's capacity to deliver and use oxygen-rich blood. The study included 160 monolingual or bilingual older adults. Half of the participants followed a 26-week home-based high-intensity interval training (HIIT) program with three weekly sessions, starting with a four-week familiarization period. Afterward, they aimed for over 80% of their ... exercise brain cardiovascular
Read moreAsthma affects millions of children, and finding ways to prevent it before birth could be a game-changer. Some evidence suggests that physical activity during pregnancy promotes fetal lung development, potentially reducing children's asthma risk. A recent study found that the children of mothers who engaged in regular physical activity during pregnancy were nearly half as likely to develop asthma. Researchers analyzed data from 963 mother-child pairs participating in the Kuopio Birth Cohort study. They gathered information on maternal physical activity during pregnancy, potential influencing f... exercise pregnancy development asthma
Read moreGraying hair is a cardinal sign of aging, typically beginning in a person’s fourth or fifth decade. Nutritional deficiencies, including low intake of protein, vitamin B12, iron, and copper, can contribute to premature graying. However, a recent review found that some medications may promote gray hair re-pigmentation. Researchers reviewed 27 studies and case reports of medication-induced gray hair re-pigmentation, totaling 133 patients. They categorized the various drugs as anti-inflammatories, stimulators of melanogenesis (the production of melanin, the pigment responsible for hair, skin, and... nutrition aging inflammation drug Hair
