.../ New research has found caffeine can help manage stress and potentially prevent conditions like depression and memory loss.

An international team of scientists from Portugal, the United States and Brazil studied how caffeine could reduce the impact of stress on the brain

... / Associate Professor Cunha and his team found caffeine blocked a stress-related chemical and prevented associated issues such as memory loss.

"What caffeine is doing is not making the system work better; what caffeine is doing is avoiding the system going into the wrong way of working," he said.

"So it's a prevention of a deterioration, rather than an improvement."

Good morning Octo, and I am enjoying my morning coffee, but it seems at the wrong time.

Quote:If we consume coffee, or any caffeine for that matter, during times of peak cortisol production, scientists say that the effect of the caffeine will not only be greatly diminished during that time, but our bodies will also build up a tolerance to the effects of caffeine. That means less buzz for you even when you’re drinking coffee at the right time.

So when are the optimal times for your daily dose?

For people who wake up between 6 a.m. and 8 a.m., cortisol levels rise during the early morning hours and begin to drop off around 9:30 a.m. Levels rise and fall again around noon and 5:30 p.m.

This means the optimal times for consuming caffeine fall somewhere around 9:30 a.m. to 11:30 a.m. and 1:30 p.m. to 5:30 p.m.

I posted this before I added the link...maybe the coffee's effect is diminished because I am drinking it at the wrong time. blink.gif

Im still buzzing on coffee. Had a break all week though, cold turkey, i was out of control.. Had one out today and it was so so.. The coffee at home is pretty amazing.. Coffee making to me is an art form. I can tell by the colour of the latte whether or not its good or not..

I try to keep about 10 Kilos in the house at all times, (22 lbs). Easy to keep good as I rotate the stock and use about 1 lb a week, replenishing when it goes on sale at the store.

There's plenty of room for all God's creatures. Right next to the mashed potatoes!

Caffeine in nectar helps with bees' memories.

Quote:But how is it working, how are the bees' memories being affected by the caffeine? While bees certainly do have brains, they aren't really similar to ours in terms of organzation. So while we have a hippocampus that has a great deal to do with memory, bees don't. Instead they have something called Kenyon cells, which help organize signals during learning in a similar way to the hippocampus. And these Kenyon cells also have adenosine receptors, the receptors that caffeine acts on to produce its effects.

The scientists hypothesized that caffeine might be acting at the Kenyon cells to produce the effects they saw on bee memory. When they applied caffeine and recorded from the Kenyon cells, they saw that caffeine acted at adenosine receptors to cause a small depolarization of the Kenyon cells, making them more likely to fire.
