It’s common to wake up in the morning and immediately drink a cup of coffee. Whether it’s as a source of energy or as a way to socialize, people often consider coffee an integral part of their daily routine. But when does consumption do more harm than good?

According to the U.S. Food and Drug Administration (FDA), a healthy adult should be able to drink an average of 400 milligrams of caffeine per day, or about four to five 8-ounce cups of coffee. The American Academy of Pediatrics advises children and adolescents not to consume caffeine, including coffee.

However, many factors can influence the effects of caffeine on the body, such as medications or caffeine sensitivity. Some people tend to switch to decaf coffee after a while, but it’s worth noting that even decaf coffee still contains caffeine — between 2 and 15 milligrams of caffeine in an 8-ounce cup, according to the FDA.

To know whether or not you’ve been overdoing your coffee intake, there are some physical symptoms you should look out for. These include insomnia, nervousness, anxiety, rapid heartbeat, stomach upset, nausea, and headaches. While not everyone experiences these symptoms after drinking too much coffee, it’s important to listen to your body and put down your cup if you start to feel the opposite effects of caffeine.

“Within these milligram or cup of coffee recommendations, if you start to feel too tired and the caffeine isn’t helping, you should stop,” Jessica Sylvester, a spokeswoman for the Academy of Nutrition and Dietetics and a registered dietitian at the Florida Nutrition Group, said in an interview with NBC News“If your heart starts beating very fast, you need to stop. It’s different for everyone.”

A person’s response to caffeine can also change with age. If you can drink three cups of cold brew at age 25, you may not be able to at age 45. If your intake exceeds 1,200 milligrams of caffeine, it can lead to more serious side effects like seizures or even death. However, for the average person, that would mean consuming more than 20 cups of coffee in a short period of time.

Although rare, it is also possible to overdose on caffeine. Some of the warning signs of a caffeine overdose may include difficulty breathing, hallucinations, confusion, agitation, dizziness, fever, irregular heartbeat, nausea, vomiting, muscle twitching, and rapid heartbeat, according to Mount Sinai.

If you think you or someone you know is overdosing on caffeine, you can call the U.S. Poison Help line at 800-222-1222 for help. If you are calling on behalf of someone else, it may be helpful to know their age and weight, as well as how much caffeine they drank and what time of day it was consumed.

People who present to emergency centers for a caffeine overdose may be treated with breathing support, such as a ventilator or oxygen, intravenous (IV) fluids, medications to treat symptoms, or even a shock to the heart to treat irregular heart rhythms.
