Why caffeins effect plant?

Why shouldn't caffeine effect plants?  Plants are living, just like humans, plants have hormones that determines its growth development.  Caffeine effects humans, so why shouldn't it effect plants?  \n\nPlants do not have a nervous system because what do plants do?  They just sit.  Due to this, plant growth and development is strictly based on the secretion of different hormones, which is why it takes them so long to respond to the outer environment.  Although some plants can immediately respond to a brush of a wind (Mimosa pudica), most like household plants move very slowly.  When given a substance like caffeine or steroids, it can have devastating effects.  In a human, caffeine simply goes to a neuron and basically occupies the Ca receptor and stimulates our muscles by keeping the flow of action potentials constant non-stop for a period of time.  A constant consumption of caffeine will result in a dead neuron, you will basically over work the neuron.  In a plant, the caffeine does not have a place to dock.  Instead, it messes up the different hormones or docks in crucial receptors that are needed for growth.  If the receptor is blocked, then the hormones cannot be expressed, causing a change in the growth pattern of the plant.  I mean, if caffeine is able to outcompete our natural signals, then it for sure can knock out a plants signal to grow in the right manner.

Caffeine is a dieuretic.  It makes water leave your tissues. \n\nH20 is much betta!

Coffee as you know contains caffeine. Depending on the variety used the caffeine content can vary.  This has the ability to stimulate the brain.  However, overdosing on caffeine can have the reverse affect.  Think Incredible Hulk Syndrome.  Further, caffeine and other substances within the coffee can speed up your heart, too fast.\n\nThe real danger comes from consuming, unwittingly, more caffeine from other sources, such Coca Cola chocolate etc.\n\nHowever, moderation is the watch word.\n\nMy favourite stimulant is TEA [Camellia sinensis]. I consume gallons of it everyday. \n\nOf course it does contain equal amounts of caffeine, as coffee.  Tea does have other inherent health properties.

Coffee can often have a paradoxical effect, in which it can actually induce sleep-this occurs generally at very high doses, or in people that are especially sensitive to it.  But, as is the case with all chemicals, there is a wide range of physiological responses in humans, and you may just be immune to the stimulatory effects of caffeine-it probably has to do with the levels of detoxifying enzymes in your liver-thus, you may be insensitive to many drugs.  This is something to be aware of if you are ever ill and need medication.

Caffeine increases heartbeat, respiration, basal metabolic rate, gastroenteric reflexes, and the production of stomach acid and urine; and it relaxes smooth muscles, notably the bronchial muscle. All of these changes vary considerably among people and may depend upon the individual's sensitivity to this drug, his/her metabolism, or upon whether the consumer habitually uses or rarely uses caffeine. How long caffeine's effects last is influenced by the person's hormonal status, whether he/she smokes or takes medications, or has a disease that impairs liver functioning.\n\nSubjectively, people report that caffeine gives them a "lift." They feel less drowsy, less fatigued, more capable of rapid and sustained intellectual effort. They also report improved performance of some manual tasks such as driving. However, caffeine may restore only those abilities or feelings the person had before fatigue or boredom set in. Studies have also shown that caffeine decreases reaction time to both visual and auditory stimuli; it does not significantly alter numerical reasoning (arithmetic skills) or short-term memory; and it can diminish performance of manual tasks that involve delicate muscular coordination and accurate timing.\n\nWhen caffeine is taken in high doses it can cause many unwanted side effects.\n\nStudies of the effect of caffeine on sleep have shown that one strong cup of coffee, drunk 30-60 minutes before going to sleep, can cause restlessness and difficulty falling asleep, increased body movements, a tendency to be awakened more readily by sudden noises, and a decreased quality of sleep.\n\nThe wide variation in caffeine's effects on sleep may be related to whether the person is a habitual, heavy user or a non-user of caffeine. Non-users report greater difficulty with sleep after consuming caffeine. Heavy users may also experience sleep disturbances; however, their increased tolerance to the effects of caffeine affects their perceptions of disturbed sleep. Often they sleep for shorter periods of time, but have grown accustomed to this pattern.\n\nIf you use caffeine and are having trouble sleeping, you may want to try cutting back on your total daily intake or avoid consumption 5-7 hours before you plan on sleeping, to allow time for the caffeine to be metabolized.

The reaction to music is an odd one. The "Mythbusters" did a segment on it once. It seemed that the more SOUND a plant recieved usually resulted in more growth. Therefore, yes music does affect plants.

Yes it does.  It is directly related to the caffeine content.  Try decaf and you should be fine.  Never drink coffee if you are taking sudafed.

It's said to have antioxidant properties, which fights free radicals in cells and helps detox the body.  Studies are still being done.  \n\nThe ill effects are that green tea has a tendency to cause diarrhea, and the usual causes from caffeine as a stimulant and a diuretic.

Yes - higher and lower pH's and different mineral contents affect plants. The safest bet would be to get the plant in the right conditions, and then water with the purest water available, preferably distilled.

decrease your caffeine intake.

Of course it does. You feel more active now that you have 200% of caffeine RDA. Depending how you react to the pills, it could increase your stress with the increase reaction or you can be extremely happy but i guess also freaky with all that energy packed in, like a kid on coffee if you will.
