POOR SLEEP DIMINSHES COGNITIVE BENEFITS OF EXERCISING
POOR SLEEP DIMINSHES COGNITIVE BENEFITS OF EXERCISING Regular physical activity may protect against cognitive decline as we age. Still, according to a new study by UCL researchers, this protective effect may be diminished for people needing more sleep. The study, published in The Lancet Healthy Longevity , looked at cognitive function over 10 years in England, 8,958 people aged 50 and over. The research team investigated how different combinations of sleep and physical activity habits might affect people's cognitive function over time. They found that people who were more physically active but had short sleep -- less than six hours on average -- had faster cognitive decline overall, meaning that after 10 years, their cognitive function was equivalent to peers who did less physical activity. Lead author Dr. Mikaela Bloomberg (UCL Institute of Epidemiology & Health Care) said: "Our study suggests that sufficient sleep may be required to get the full cognitive benefits of ...
