Cognitive decline is not inevitable. Researchers from the University of Florida have just proven it using MRI and the solutions are within everyone’s reach.
Your brain may be a very different age than the one on your ID card. A University of Florida study published in Brain Communications demonstrated this using MRI scans processed by artificial intelligence. The result: people who adopted several protective habits had brains that looked eight years younger than their actual age. And the more good habits accumulated, the greater the benefit.
The first of these habits is quality sleep. It is even the most powerful of all in the study. Restorative sleep, that is to say sufficient, regular and without frequent awakenings, was one of the factors most strongly associated with a biologically younger brain. “Poor sleep can be cured”recalls Dr. Jared Tanner, one of the leaders of the study. “It’s not inevitable.”
Second lever: learn to manage your stress differently. Participants who perceived stress as less threatening through simple techniques like relaxation or breathing had brains that aged more slowly. “We can learn to perceive stress differently”emphasizes Dr Tanner. “It’s something people have control over.”
Third factor: social relationships. Participants who had strong ties and quality entourage showed younger brains and aged more slowly over the two years of follow-up. No need for a big circle — the depth of the links mattered more than their number.
Maintaining a healthy weight came in fourth place, linked to a brain that appears younger on images. Finally, not smoking was among the most protective behaviors: tobacco accelerates brain aging and reduces blood flow to the brain.
The big lesson from this study: these five habits act cumulatively. Each additional factor brings a measurable benefit. “For every additional protective behavior, there is evidence of a neurological benefit”concludes Dr. Kimberly Sibille, co-author of the study. Lifestyle is medicine.
