Your chronological age may be fixed, but your brain age isn’t. A recent University of Florida study reveals that everyday habits such as quality sleep, optimism, stress management and strong social connections can slow brain ageing by up to eight years. Using MRI scans and machine learning, researchers found that lifestyle choices play a powerful role in maintaining brain health even among people living with chronic pain.

Highlights

Brain age can differ significantly from chronological age
University of Florida study links lifestyle habits to slower brain ageing
MRI scans and machine learning used to measure brain age gap
Optimism, sleep and social ties shown to protect brain health

Your birth certificate might say you're 65 years old but your brain can still remain far younger or older, maybe of 55 or 70s. Maybe it's how you treat yourself determind age of your brain. Recently University of Floridda publish a study that links habits to slower brain ageing. According to the study, brain health is not fixed; it's shaped by daily choices and mindset. So if you develop simple, controllable habits that can make your brain appear up to eight years younger. This article will explore how brain age is measured, what habits protect the brian and why it matters.

What Does “Brain Age” Really Mean?

Brain Ageing

Brain age is a kind of snapshot of an individual's overall brain health so it refers to how old a person's brain appears on scans not how old a person is. A younger brain age means the brain has healthier neural networks. Older-looking brains mean they are prone to cognitive decline increasing the risk of dementia or Alzheimer's disease.

How Scientists Measured Brain Ageing

Optimism and Brain Health

The study was conducted around 128 adults in midlife and older age. Many are living with chronic musculoskeletal pain or are at risk of knee osteoarthritis. The MRI scans taken over two years where machine learning used to analyse brain structure. The approach is important because it looks at the whole brain not isolated areas and captures the combined effects of pain, stress and lifestyle.

The study observed that people linked to older appearing brains are going through chronic pain or long-term stress or lower income or social isolation.

Protective Habits That Keep the Brain Young

The study highlighted key habits that added protection and additive benefits to the brain such as quality time, which allows the brain to repair and reset. Optimism helps an individual to manage stress and cope. If an individual has strong social connections, that also protects against cognitive decline. Non-smokers or those who avoid tobacco, it prevents accelerated neural ageing.
