Coffee helps a lot of us get out of bed and get on with the day. Some of us simply drink it for the sheer joy of it. But how much coffee is too much for you? And what happens beyond a limit? Read on to find out.
Up to 400 milligrams (mg) of caffeine a day appears to be safe for most healthy adults. That’s almost the amount of caffeine in four cups of brewed coffee.
So what happens when you drink too much coffee?
Coffee’s effects on the brain are actually quite profound.
- You might find coffee addicts suffer from anxiety and show erratic, irritable behavior. This results from over activity of the sympathetic nervous system.
- Hallucinations, restlessness and insomnia might also be experienced.
- Fast heartbeat and muscle tremors might also be felt.
- Caffeine has been shown to relax the esophagus, contributing to gastro-esophageal re-flux. This can either cause or aggravate heartburn in vulnerable individuals.
While giving up caffeine addiction instantly might be difficult, you can slowly decrease your caffeine intake.
