How Much Coffee Is Too Much for Older Adults?

For many Kiwis, the day starts with a flat white at the café or a hot cup from the plunger at home. Coffee is a comforting ritual, and for most older adults a cup or two is perfectly fine. But as we age, our bodies handle caffeine differently, so it pays to know when too much coffee becomes a problem.
What counts as too much coffee?
General guidance for healthy adults is to keep caffeine to around 400 milligrams a day, which is roughly three to four cups of home-brewed coffee. Older adults often feel better with less. Caffeine stays in the body longer as we age, so an afternoon cup may still be affecting you at bedtime. Café coffees can also be stronger than you expect, especially a double shot, so count your cups out and about as well as at home.
Signs you may be having too much coffee
Common signs include trouble sleeping, jitteriness, a racing or fluttering heartbeat, headaches, an upset stomach and feeling anxious or restless. Some people also find they need the toilet more often, which can be a nuisance for those already dealing with bladder concerns. If you notice these after your usual cuppa, your body may be telling you it is too much coffee.
Why age and health matter
Coffee can interact with some health conditions and medicines. Caffeine may raise blood pressure for a short time, and heavy intake has been linked with reduced calcium absorption, which matters for bone health. Certain medications, including some for the heart, thyroid and mood, can be affected by caffeine. It is worth asking your GP or pharmacist whether your usual amount suits you.
Simple ways to cut back
Try a smaller cup, have your last coffee before midday, or swap one cup for decaf or herbal tea. Cut down slowly over a week or two to avoid withdrawal headaches. Drink plenty of water through the day, and enjoy your coffee with food if it upsets your stomach.
Enjoy it, in balance
There is no need to give up coffee. The key is balance and listening to your body. If you are unsure whether you are having too much coffee, chat with your doctor or pharmacist at your next visit.
