Falls at a care home are down by over a third since residents stopped drinking coffee.
They also sleep better and enjoy improved mental health after quitting caffeine.
Coffee can lead to more falls because it makes people need the loo more often and more urgently, leading them to rush to the toilet.
Staff at Bramley Court care home in Cambridge have also noticed a positive impact on their own wellbeing.
Manager Judith Wroe drank over 20 cups of coffee a day before the trial and has cut down to just one in the morning.
She said: “My blood pressure has significantly improved, my sleep has never been better, and I feel more focused throughout the day.
“We’re excited to continue championing initiatives like this.
“We’ve been able to reduce the need for one-to-one support while increasing the quality of care.
“This has been life-changing for both residents and our team.”
The home is trialling the ban in collaboration with Anglia Ruskin University and Care England. Falls are down 35%, Care England said, and if rolled out nationwide, this could save the NHS £85million a year.
Head of quality Carol Morgan said: “We’ve seen more relaxed body language, improved mood, and better engagement in activities.
“Residents who were once tearful or anxious are now spending time with friends, taking part in daily life, and enjoying improved wellbeing and engagement in their home life.
“The whole team has noticed this approach has transformed not just the residents’ health but their social lives too.”
