A new study from Chinese researchers, analysing data from 96,408 participants in the UK Biobank, has found that incorporating short, vigorous bursts of activity into daily life—known as 'exercise snacking'—can significantly reduce the risk of developing dementia and other common diseases.
Over a seven-year period, participants who engaged in vigorous exercise had a 63% lower risk of dementia compared to those who did no vigorous activity. The benefits extended to other conditions, including heart disease, type 2 diabetes and liver disease, with effects persisting even when exercise time was modest.
Fitness experts define exercise snacking as brief, high-intensity movements—typically five to ten minutes—woven into daily routines. Monty Simmons, a personal trainer in London, says the concept involves 'taking yourself away from your desk and moving for five or 10 minutes' to keep the body limber and reduce stiffness.
Darren Sealy, co-founder of Flow State Fit Club, adds that these mini workouts 'raise your heart rate and boost your cardio and metabolic conditioning,' and that regular short sessions can compound into significant health benefits over the week. Simmons suggests exercises such as standing back bends, star jumps, jogging on the spot, lunges or push-ups.
To maintain consistency, Sealy recommends picking a set time each day to build a habit. For those in an office, subtle activities like a brisk walk or discreet stretching can be effective. The research underscores that substantial health gains do not require a rigid gym schedule, but rather frequent, intense 'snacks' of movement.
