Drinking Tea reduces stress written 11 years ago

Tigger - Tea

This study pretty much confirms what every mother in the world knows — drinking tea reduces stress. Any stressful situation is usually followed by “oh; best put the kettle on”.

Drinking tea has been shown to reduce the amounts cortisol is the blood after a stressful event. In the study participants were given either black fruit tea or a tea-placebo with the same taste/appearance as tea. They were then subjected to stressful events and their cortisol levels tested. It turned out that those drinking the real tea had much more reduced levels of cortisol in their body after 50minutes after the stressful event.

I really do need to get paper copies of these science journals; just so that when I’m telling people about this it’s not just “from some article on the internet…”.

Since it is a stimulant, caffeine in tea increases alertness and quickness of response, and often briefly improves mood. It is a mild diuretic. In large doses, it can produce jitteryness, anxiety, and insomnia. As with any stimulant, the period of enhanced alertness and heightened mood is generally followed by a period of depressed mood and ability.

Caffeine is also an addictive drug if taken regularly. Caffeine addiction is probably the most common drug addiction in the world, with nicotine addiction a close second. One important side effect (and a frequent cause of medical advice to limit or stop caffeine use) is SLEEP DISRUPTION. Many other unwanted effects are associated not so much with use as with withdrawal. Prominent among these effects is the withdrawal headache, caused by dilation of blood vessels in the head that had been constricted by the consumption of caffeine. Other side effects of withdrawal, usually found in frequent and heavy users of caffeine, are lethargy, irritability, and constipation. so there you go, tea is bad too

Many of the things you mention aren’t what I would call “bad” points of drinking tea.

First thing to note is that on average tea has less than half the caffeine amount than coffee, and many studies on the effects of caffeine on the body focus on caffeine derived from coffee. So whilst many people are addicted to caffeine in the form of coffee; it’s twice as hard to become addicted whilst drinking it in the form of tea.

Tea, is in fact, not a diuretic. It does not contain sufficient caffeine amounts (50mg) to cause a diuretic effect (closer to 250—300mg).

Tea contains much more than just caffeine though, the antioxidants and vitamins provide a significant addition to your daily intake. As described in the article above tea also contains a source of fluoride which makes for healthier teeth.

As with many things in life, tea is best done in moderation. Drunk sensibly will have positive effects on your health, and can even provide enhancements to mood/performance when desired.

i was just trying to even up the sides of the argument. BUt as an interesting few points to add to your story:

Scientists working with a mouse model of Parkinson’s disease have found that caffeine prevents the loss of the neurotransmitter dopamine, which is depleted in the neurodegenerative illness. If the new findings are any indication of caffeine’s effects in humans, a coffee a day may help keep Parkinson’s away. The results of this study will be published in the May 15 issue of the journal Neurology. And also http://cat.inist.fr/?aModele=afficheN&cpsidt=17400829 shows interesting experiements done on caffeine doped rats to see how they responded sexually. But darn you for using the “alls good in moderation” bit
