Coffee lovers, take heart: Women who drink four or more cups of caffeinated
coffee daily appear to have a lower hazard of melancholy
Than those that do not drink coffee or stop at one cup a day, a new study implies.
Although it is way too early to start recommending regular coffee
consumption as a way to prevent
Depression, those that feel guilty about their custom may be comforted by the findings.
“This may decrease worries that caffeine ingestion will have
An adverse impact,” said Dr. Christopher Cargile, an associate professor
of psychiatry and behavioral science at Texas A&M Health Science Center
College of Medicine. “Caffein at high doses has for ages been associated with
Worsening of tension as well as other psychiatric illness, and at times this has lead
to ongoing concerns that it might be best to limit its use.”

The lion’s share in the world — 80 percent of caffein —
Is consumed in the kind of caffeine and coffee is the most broadly used
central nervous system stimulant in the world.
Scientists have probed the effect of caffeine on heart health, mark
of inflammation and cancer (normally the effects are benign as well as positive),
However there’s been comparatively little research into its effects on mood.
What little research has been done has typically discovered a salubrious
Effect, with increased coffee being as well as decreasing depressive symptoms
associated using a lower threat of suicide.
“Caffeine has short term favorable effects on mood, subjective
feelings of having more energy and being more awake in the short term,”
said study senior author Dr. Alberto Ascherio, who’s a professor of
epidemiology and nutrition at Harvard School of Public Health in Boston.
It looked natural “to see whether long term coffee consumption
associated having a lower danger
of growing depression,” he added.
These authors tracked, averaging girls nearly 51,000
were participating in the Nurses’ Health Study. None of the women reported
being depressed at the start of the research and none were on antidepressants.
Depression was quantified by new investigations accompanied by long term
Usage of antidepressants.
Girls who drank four cups of coffee or more a day had a 20 percent
Decreased risk for depression and people imbibing two to three cups daily had a 15
Risk was decreased by percent, compared to those drinking one cup or less daily.
Decaffeinated versions of the drink didn’t seem to be linked at all
A relationship between depression and caffeinated coffee does make
a certain quantity of biological sense, pros say.
“Caffeine is recognized to influence the release of several
Neurotransmitters, including serotonin and dopamine, that were implicated
in regulating mood as well as melancholy,” said Ascherio, who is also professor
of medicine at Harvard Medical School.
But those are short term effects and “we [still] do not actually
know why coffee [over] years can decrease depression,” he said.
“If caffeine has some antidepressant effect, we may find a way to
find compounds with an even more powerful antidepressant effect,” Ascherio
First, though, researchers need to discover whether there is a
cause-and-effect relationship at work here.
“Now there’s simply too much we do not know about the
Cause and effect relationship that could be producing these findings,” said
Cargile, who is regional associate dean of Texas A&M’s Bryan College
