Just 2 Drinks Slow Reactions In Older People
Blood alcohol levels below the current legal limit for driving have a significant negative effect on a person's dexterity. Researchers writing in the open access journal BMC Research Notes found that just two single vodka and orange drinks were enough to make senior volunteers struggle at an obstacle avoidance test while walking.
Judith Hegeman worked with a team of researchers from Sint Maartenskliniek, Nijmegen, The Netherlands, to carry out the tests in 13 healthy men and women (average age 61.5yrs or 62yrs). She said, "The results clearly show that even with low blood alcohol concentrations, reactions to sudden gait perturbations are seriously affected. After ingestion of 2 alcoholic drinks, obstacles were hit twice as often, response times were delayed and response amplitudes were reduced. These changes were most obvious in situations with little available response time".
