Some of the signs that you are drinking a lot of coffee

How much coffee is considered too much? You may be surprised, but in fact it is recommended that people do not drink more than 28 cups of coffee a week, which is approximately four cups of coffee a day.

However, consuming more than that can have negative effects on health – especially on longevity.

Feeling anxious
An average cup contains 95 milligrams of caffeine. So if you drank more than four cups of coffee, you would get about 500 milligrams of caffeine a day. A study in the Journal of Psychopharmacology reports that consuming caffeine in this mass can cause high levels of stress, anxiety and even depression. Consumption of more than 1000 milligrams of caffeine per week has been shown in research as a predictor of high anxiety.

Anxiety and stress are things that need to be treated with a medical professional, and to do this it is important to also evaluate caffeine intake and discuss possible changes in habits in this regard.

Difficulty sleeping

Regular coffee consumption can cause problems with normal sleep habits, especially if you drink coffee regularly in the afternoon. A study of 197 high school students found that those who took more caffeine woke up earlier and were more drowsy during the day compared to the group that swallowed less caffeine. Although regular coffee drinking has many health benefits, it is recommended to keep your daily coffee intake to a minimum, in the morning, to have a better night’s sleep.

Accelerated heartbeat

A controlled study found that drinking 100 milligrams of caffeine every hour for up to five hours does not cause a rapid heartbeat. However, it has been found that drinking large amounts can still lead to heart rate change.


Have you ever experienced tremors after many cups of coffee? This can actually be defined as a caffeine overdose. Healthline points out that it can cause headaches, irritability, difficulty sleeping and increased heart rate. If you have any of these serious side effects, you should seek medical attention.

Feeling tired

It is natural to turn to coffee or other forms of caffeine when you feel tired. But did you know that too much caffeine can actually have a negative effect? Especially if it includes added sugars. A study published by Innovations in Clinical Neuroscience found that regular consumption of caffeinated beverages, especially sugary ones, caused mental fatigue in participants.
