Can caffeine kill brain cells?
If you were to take a culture of brain cells on a petri dish and submerge them in a caffeine solution, it probably would. But in people, is drinking coffee going to kill brain cells? No. Even very high amounts would not.

The Buffalo Theory as told by Cliff Clavin: No one can explain this as well as Cliff Clavin, on Cheers. One afternoon at Cheers, Cliff Clavin was explaining the Buffalo Theory… to his buddy Norm. and here's how it went: "Well ya see, Norm, it's like this... A herd of buffalo can only move as fast as the slowest buffalo. And when the herd is hunted, it is the slowest and weakest ones at the back that are killed first. This natural selection is good for the herd as a whole, because the general speed and health of the whole group keeps improving by the regular killing of the weakest members. "In much the same way, the human brain can only operate as fast as the slowest brain cells. Excessive intake of alcohol, as we know, kills brain cells. But naturally it attacks the slowest and weakest brain cells first. In this way, regular consumption of beer eliminates the weaker brain cells, making the brain a faster and more efficient machine. That's why you always feel smarter after a few beers." . In reality, alcohol does kill brain cells. That's an old myth promoted by temperance activists who wanted to scare people into total abstinence from alcohol.
It's not that there is anything in caffeine that kills plants, it is the caffeine itself. Caffeine is a toxin produced by some plants to ward off predators, but is lethal to …plant cells when artificially introduced.
Ink does not directly kill brain cells. However, the metals andtoxins in ink can kill brain and other cells and is not good forthe body or your health as a whole.
No. Brain freeze is a headache most commonly associated with the quick consumption of cold substances, such as ice cream. When the cold substance comes into contact with yo…ur palate or the roof of your mouth and sinus cavities it causes the blood vessels to vasoconstrict or get smaller. As the palate warms the blood vessels dilate. This rapid constriction and dilation is detected by pain receptors that travel to the brain via the trigaminal nerve, which also serves as one of the major nerves for the facial area. Because the pain signal travels with the signals coming from the face, the brain thinks it is feeling pain in the face that isn't really there, this is called referred pain. The only way the brain is effected is how it perceives the information received from the nerve. http://wiki.answers.com/What_does_a_brain_freeze_do_to_the_brain#ixzz17kJwkNDd .
yes hairspray does kill brain sells
no, well not enough to make the slight difference to anything ever.
most likely yes because it kills nutrients in healthy foods
PCP or acid IMO. You hear stories about people on acid that never came down.
It really depends cell phones can give brain tumors if you talk to long but normal phones don't. It's because of the radiation they also can cause brain cancer. (fyi changing …ears every once in a while when you talk on a phone will lower the chance of a brain tumor or brain cancer) Yes it does, especially if you keep it in your pockets it'll kill your sperm cells or egg cells. if you keep it in your shirt-pocket it can give you a different type of cancer.
no you retard
yes because it can damage the brainsteam
Actually, anger induces emotional stress, which takes a toll onbrain cells by increasing adrenergic activity via the HPA(hypothalamic-pituitary-adrenal) axis. This causes incr…eases incortisol, a stress hormone. Emotional stress also inducescumulative cellular damage due to increases in what is calledoxidative stress (the increased metabolic breakdown of cellularmaterials leading to free radical production). While young persons have bodies that have much less cumulativedamage (due to youth), and have active DNA and cellular repairmechanisms, as people get older, these repair mechanisms accumulatedamage themselves (through environmental factors and even thecells' own metabolic processes), and they work less effectively. Since emotional/oxidate stress has been shown to increase the"load" on cells, increasing the rate of this damage, the older aperson gets, and the more stress the body is under, the more likelytheir cells will be unable to repair this damage, and the morelikely that brain cell death will increase. Now, there are many other, more pronounced mechanisms that resultin brain cell death or deactivation in the presence of emotionalstress. The homeostatic, regulatory factors of the brain can senseprolonged adrenergic stress and will downregulate (desensitize)certain neural pathways in order to minimize the stress signal. Italso "rewires" certain neural pathways to adapt to stressfulenvironments. Large-scale changes based on high-stress are oftenfound in neurotic (anxiety) disorders and in PTSD (post-traumaticstress disorder).
Not immediately. Helium has many negative effects on the brain. Bubbles of helium can travel to the arteries that lead to your brain. Inhaling the gas won't kill brain cells o…n its own, but sucking it in can cause oxygen deprivation, which can lead to your precious brain cells slowly dying.
it doesnt. its very educational. well... kinda. i guess. but i watch it all the time and it doesnt kill my brain cells. i think.
no but too much salt can because if you have too much salt in your cells than water the cell will burst
