Bad Sleep Makes Your Brain Age Faster, Study Finds

People who struggle with poor sleep tend to have brains that look older than their actual age, according to an extensive brain imaging study conducted by Karolinska Institutet and published in eBioMedicine. The researchers suggest that increased inflammation in the body could help explain this connection. Although poor sleep has long been associated with dementia, scientists still debate whether unhealthy sleep patterns contribute to cognitive decline or if they are early signs of the disease. In this new investigation, the Karolinska...

The impacts of different dietary restriction regimens on aging and longevity: from yeast to humans

By Tsui-Ting Ching & Ao-Lin Hsu Dietary restriction (DR) refers to a broad set of interventions that limit the intake of specific nutrients or overall food consumption, either in quantity or timing, without causing malnutrition. DR has long been considered the most robust intervention for increasing healthspan and lifespan. This includes, not exhaustively, caloric restriction (CR), protein restriction (PR), amino acid restriction (AAR), intermittent fasting (IF), and time-restricted fasting (TRF), each with overlapping but distinct metabolic and physiological effects. This...

A systematic review and meta-analysis of air pollution and increased risk of frailty

By Zahra Jafari, Melissa Andrew & Kenneth Rockwood Background Environmental air pollution is increasingly recognised as a potential contributor to frailty. This systematic review and meta-analysis aimed to synthesise existing evidence on the associations between environmental air pollution and frailty in middle-aged and older adults, providing insights into the impact of air pollution on public health. Methods The systematic review and meta-analysis were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement 2020. Four electronic databases were searched without...

Frailty in ageing populations worsened by air pollution, global review finds

Air pollution increases the likelihood of people becoming frail in middle and old age, according to an international review of studies. People are living longer and, while this is often painted as a challenge to healthcare systems, it is also something to celebrate. There are many opportunities to increase the quality of life in old age, maximise independence and minimise the amount time spent being ill. Dr Zahra Jafari, from Dalhousie University and coauthor of the review, said: “Frailty is a critical health outcome...

Healthy ageing: Are we on track?

The world is ageing at an unprecedented pace. The change in global demography caused by population ageing has been a notable phenomenon in recent times. The global population of people aged 60 and above is expected to increase from 1.1 billion in 2023 to 1.4 billion in 2030. Moreover, the pace of population ageing has been significantly faster than in the past, with an estimated increase in the proportion of older people in the global population from 12% to 22% between 2015 and 2050. Between 1974...

Power Of Friendship Can Slow Down Ageing, Study Finds

Friendships that have survived the odds and persevered for years can help slow down biological ageing, a new study has found. Such relationships and engagement may 'reset' the body's internal clocks to lower the biological age, the research published in the journal Brain, Behavior & Immunity - Health, highlighted. Drawing on data from 2117 adults who participated in a study called the Midlife in the United States, researchers noted that people with greater "cumulative social advantage" showed slower rates of biological...

Aging, Alcohol, and Attrition: The Economic and Political Ramifications of Public Health in Contemporary Russia

By Andrew Kelmanson, Anonymous Author, Emily Sehati, Eliana Svilik, Kyle H. Chan, Marcus Hsieh & Will Pirone The Russo-Ukrainian War has exacerbated several of the country’s existing public health crises. Specifically, this paper identifies 3 areas of public health concern that are inflamed by the conflict in Ukraine that will likely have an outsized effect on the economic success and political legitimacy of the country in the coming years. These are, namely, alcohol addiction, an aging population, and attrition from...

Social infrastructure law in the UK, EU and US

By Ewan McGaughey What should be the goals of social infrastructure, and the best means to achieve them? Social infrastructure is a new term to describe the welfare state, whose conceptual foundations were laid in Lord Beveridge’s Report, Social Insurance and Allied Services (1942). A good government, said Beveridge, should tackle five evil ‘giants’, namely disease, ignorance, squalor, idleness, and want. These could be overcome with a universal free health service, public education, public housing, full employment, and income insurance...

Mexico’s Politics Of Pensions

Like many countries with an aging population, Mexico is facing a pension crisis. In just the last five years, the universal pension for older adults quadrupled its budget. Coupled with low growth, the ever-rising cash transfers and subsidies have become a major drag on the country’s economy. Welfare payments to individuals—such as the universal pension for older adults, disability pensions, and student stipends—have grown at a pace that outstripped investment in infrastructure, education, and security. These programs are politically attractive:...

A Common Assumption About Aging May Be Wrong, Study Suggests

A new analysis of data gathered from a small Indigenous population in the Bolivian Amazon suggests some of our basic assumptions about the biological process of aging might be wrong. Inflammation is a natural immune response that protects the body from injury or infection. Scientists have long believed that long-term, low-grade inflammation — also known as “inflammaging” — is a universal hallmark of getting older. But this new data raises the question of whether inflammation is directly linked to aging...
