Anxiety

Although low-to-moderate doses of caffeine can increase alertness, larger amounts may lead to anxiety or edginess. Monitor your own response in order to determine how much you can tolerate.

Insomnia

Caffeine can help you stay awake during the day, but it may negatively impact your sleep quality and quantity. Cut off your caffeine consumption by the early afternoon to avoid sleeping problems.

Digestive issues

Although small to moderate amounts of coffee can improve gut motility, larger dosages may lead
to loose stools or GERD. Reducing your coffee intake or switching to tea may be beneficial.

Muscle breakdown

People may develop rhabdomyolysis, or the breakdown of damaged muscle, after they ingest
large amounts of caffeine. Limit your intake to 250 mg per day if you’re uncertain of your tolerance.

Addiction

Going without caffeine for several hours may lead to psychological or physical withdrawal symptoms in those who consume large amounts on a daily basis.

High blood pressure

Caffeine seems to raise blood pressure when consumed at high doses or prior to exercise, as
well as in people who rarely consume it. But this effect may only be temporary, so it’s best to monitor your response.

Rapid heart rate

Large doses of caffeine may increase heart rate or rhythm in some people. These effects appear
to vary greatly from person to person. If you feel them, consider reducing your intake.

Fatigue

Although caffeine provides energy, it can indirectly lead to fatigue when its effects wear off. Aim for moderate caffeine intake to help minimize rebound fatigue.

Frequent urination and urgency

High caffeine intake has been linked to increased urinary frequency and urgency in several studies. Reducing your intake may improve these symptoms.
