Täyttä humpuukia. Kofeiini kohottaa veren stressihormonipitoisuutta, tämä on tiedetty jo vuosikymeniä. Adenosiinireseptorien lisääntyminen johtuu juuri siitä, että kofeiini estää adenosiinin toimintaa ja kohottaa elimistön stressiä stressihormonien kautta. Kofeiini lisää myös dopamiinireseptorien tiheyttä basaaliganglian striatumissa 120%, koska stressihormonit heikentävät ko. elimen toimintaa niin paljon, että se tarvitsee yli kaksi kertaa normaaliannoksen dopamiinia toimiakseen normaalisti.

Coffee, caffeine, and risk of depression among women.

CONCLUSIONS:

In this large longitudinal study, we found that depression risk decreases with increasing caffeinated coffee consumption. Further investigations are needed to confirm this finding and to determine whether usual caffeinated coffee consumption can contribute to depression prevention.

Coffee, caffeine, and risk of completed suicide: results from three prospective cohorts of American adults.

CONCLUSIONS:

These results from three large cohorts support an association between caffeine consumption and lower risk of suicide

Coffee drinking tied to lower risk of suicide
 
Researchers link caffeine’s impact on brain chemicals as playing key role

...“Unlike previous investigations, we were able to assess association of consumption of caffeinated and non-caffeinated beverages, and we identify caffeine as the most likely candidate of any putative protective effect of coffee,” said lead researcher Michel Lucas, research fellow in the Department of Nutrition at HSPH.

Ööö...

Mutta joo, kun kerran halutaa laitella linkkei, niin mie kaivelin hiukka omia arkistoja. 

Without further ado...

Kawachi I, Willett W C, Colditz G A, ym.: A prospective study of coffee drinking and suicide in women. Arch Intern Med 156: 521–525, 1996

Methods:  We conducted a 10-year follow-up study (1980 to 1990) in an ongoing cohort of 86 626 US female registered nurses aged 34 to 59 years in 1980, who were free of diagnosed coronary heart disease, stroke, or cancer. Information on coffee and caffeine intake was collected by a semiquantitative food frequency questionnaire in 1980. Deaths from suicide were determined by physician review of death certificates.

Conclusions:  The data suggest a strong inverse association between coffee intake and risk of suicide. Whether regular intake of coffee or caffeine has clinically significant effects on the maintenance of affect or the prevention of depression merits further investigation in clinical trials and population-based prospective studies.(Arch Intern Med. 1996;156:521-525)

Abstract

Except for conflicting evidence about coffee and risk of coronary disease, coffee and tea are not linked to major causes of death. Because of widespread use of both beverages and limitations of prior studies, concern persists. Using Cox models (ten covariates) we studied relations in 128,934 persons to 4501 subsequent deaths. Except for slightly increased risk from acute myocardial infarction among heavier (> or = 4 cups/d) coffee users (relative risk versus nondrinkers = 1.4, 95% confidence interval = 1.0 to 1.9, P = 0.07), there was no increased risk of mortality for all deaths (relative risk per cup of coffee per day = 0.99, 95% confidence interval = 0.97 to 1.01; relative risk per cup of tea per day = 0.98, 95% confidence interval = 0.96 to 1.00) or major causes in adjusted analyses. Coffee was related to lower risk of liver cirrhosis death (relative risk per cup of coffee per day = 0.77, 95% confidence interval = 0.67 to 0.89). Use of both beverages was related to a lower risk of suicide, progressively lower at higher coffee intake (relative risk per cup of coffee per day = 0.87, 95% confidence interval = 0.77 to 0.98). We conclude that coffee and tea have no overall relation to mortality risk. If coffee increases coronary risk, this is balanced by an unexplained lower risk of other conditions, notably cirrhosis and suicide.
