Watch nowScientists have long believed that physical activity can enhance memory by inducing changes in the brain's structure and function. A recent study found that after 10 weeks of cardiovascular exercise combined with a vocabulary learning task, participants who exhibited larger increases in immune system signaling molecules also experienced stronger short-term learning improvements. Researchers assigned participants to either a cycling group or a stretching group. Each person completed 18 sessions over 10 weeks, always learning vocabulary words right before exercising. The cycling group rode stati... exercise memory
Read moreA consistent daily schedule may do more than support sleep—it could also help maintain physical fitness as we age. Robust evidence suggests that disruptions in circadian rhythms, such as those caused by shift work or jet lag, are linked to poorer health outcomes. A recent study found that older adults with more regular daily activity patterns had better cardiorespiratory fitness and walked more efficiently than those with inconsistent routines. Researchers analyzed data from nearly 800 older adults (average age 76) who wore wrist devices that continuously monitored their movement. They measure... aging circadian rhythm exercise
Read moreTraining in hot conditions can drive marked improvements in endurance by triggering cardiovascular and thermoregulatory adaptations. However, access to heat training chambers is limited, and the physical demands of exercising in high temperatures can be risky or impractical. A recent study found that sitting in a sauna or soaking in hot water after exercise—a practice known as "passive heat acclimation"—might offer some of the same benefits as working out in the heat, but the evidence was weak and inconsistent. Researchers reviewed 10 studies involving nearly 200 healthy adults, comparing thos... exercise heat stress sauna
Read moreDiets that require daily calorie cutting are hard to adhere to, and most people gain the weight back within a year. Intermittent fasting, which involves eating very little on some days and freely on others, might offer a more sustainable alternative. A recent study found that fasting three nonconsecutive days per week promoted more weight loss than daily calorie restriction as part of a comprehensive weight loss program. Researchers assigned 165 adults aged 18 to 60 with a body mass index between 27 and 46 to one of two diet plans. One group followed a 4:3 intermittent fasting schedule, eating... diet obesity fasting weight loss
Read moreModern workplace changes driven by technology are transforming not only how we work but also how well we sleep. Longer hours spent at desks, increasing reliance on computers, and nontraditional work schedules may undermine sleep health. A recent study found that modern job designs are linked to distinct sleep challenges among full-time workers. Researchers analyzed data from nearly 1,300 adults in the Midlife in the United States (https://www.nia.nih.gov/research/resource/midlife-united-states) study, collected at two points over a decade. They examined six sleep health dimensions, including... sleep circadian rhythm
Read moreThe limbic system – a complex system of nerves and networks in the brain – supports many brain functions, including memory, emotion, and learning. The olfactory system is the only sensory system directly linked to this critical brain region. A new study shows that olfactory stimulation via aromatherapy may enhance limbic system function, potentially preserving or improving cognitive function in older adults. Researchers assigned 23 older adults (aged 60 to 85) to an olfactory-enriched or control group. Using an aromatherapy diffuser, they exposed the enriched group to seven essential oil scen... brain alzheimer's memory dementia nose
Read moreScientists find that visceral fat, a type of adipose tissue that produces high levels of inflammatory signals known as adipokines, impair learning and memory in mice by setting off an inflammatory cascade mediated by the release of IL-1 beta, which crosses the blood-brain barrier leading to chronic activation of microglia. From the article: > "We have identified a specific signal that is generated in visceral fat, released into the blood that gets through the blood brain barrier and into the brain where it activates microglia and impairs cognition." Visceral fat as the ring leader: > The... brain inflammation memory fat dementia weight loss nlrp3 visceral fat
