If you rely on daily
doses of caffeine to chase away
fatigue and perk up your disposition, you aren't alone. Nine out of 10
Americans consume some type of caffeine regularly, making it the most
popular behavior-altering drug.
For most people,
moderate doses of caffeine - 200 to 300
milligrams (mg), or about two to four cups of brewed coffee a day —
aren't harmful. But some circumstances, such as caffeine sensitivity or
use of certain medications, may warrant limiting or even ending your
caffeine routine. Find out if you need to decaffeinate your diet and,
if so, how you can do it with minimal distress.
For your health:
When to cut your caffeine use
Certain
circumstances call for reducing the amount of caffeine you consume.
Evaluate your habits. If any of these situations apply, you may need to
cut back.
You consume
unhealthy amounts
Though moderate caffeine intake
isn't likely to cause harm, too much can noticeably affect your health.
Heavy daily caffeine use — more than 500 to 600 mg a day, or about
four
to seven cups of coffee — can cause:
- Restlessness
- Anxiety
- Irritability
- Muscle tremors
- Sleeplessness
- Headaches
- Nausea, diarrhea
or other gastrointestinal problems
- Abnormal heart
rhythms
You have caffeine
sensitivity
If you're susceptible to the effects of caffeine, just small amounts
—
even one cup of coffee or tea — may prompt unwanted effects, such as
anxiety, restlessness and irritability. The more sensitive you are to
caffeine, the less you need to consume before feeling its influence.
Your sensitivity
depends on many factors, including:
- Body mass.
People with smaller body masses
feel the effects of caffeine sooner than those with larger body masses.
- History of
caffeine use. People who don't
regularly consume caffeine tend to be more susceptible to its negative
effects than people who do.
- Stress.
All types of stress — for example,
psychological stress or heat stress — can increase a person's
sensitivity to caffeine.
Other factors can
contribute to variations in caffeine
sensitivity as
well, including age, smoking habits, drug or hormone use, and other
health conditions, such as anxiety disorders.
