- People who drink too much coffee are at risk of caffeine
psychosis, according to a new report. It found that too much caffeine can
lead to marked changes in personality and make drinkers more aggressive,
anxious and temperamental.
- "Caffeinism" puts sufferers at further risk
of anxiety neurosis, irregular heart beats, insomnia, muscle twitches,
and nervous irritability.
- The warning comes a week after Tony Blair suffered an
irregular heart beat, which he reportedly blamed on too much strong continental
coffee at the European Union summit in Brussels. The supraventricular tachycardia,
or SVT, that he suffered can be triggered by caffeine.
- In the new report, on the potential effects of caffeine
on police hostage negotiators, Professor Wayman Mullins of Southwest Texas
State University warns: "Tachycardia could be anxiety-producing and
lead to the negotiator's stress level rising to abnormal levels,"
he says in the Journal of Police Crisis Negotiations. "The negotiator
would likely become overly anxious, nervous, frightened, and concentrate
on what was occurring physiologically and not on the hostage-taker."
- Caffeine has also been linked to other health problems:
other research has blamed too much coffee with the increased risk of rheumatoid
arthritis,miscarriages and epilepsy. Research also shows that drinking
four or five cups of coffee a day makes the body behave as if it is under
constant stress by increasing the levels of stress hormones. That can raise
blood pressure, with a risk of long-term heart disease.
- But it is not all bad news for coffee lovers. Researchers
have shown that drinking two to four cups a day can lower the risk of colon
cancer, gallstones, cirrhosis of the liver and Parkinson's disease. It
can also increase male fertility.
