Coffee may fail to give you the kick if you drink it all the time. A new research has found that drinking coffee regularly can make your body immune to the stimulatory effects of caffeine.
People who seek a cup of coffee every morning to kickstart their day, might be able to do without it as well. Experts suggest that regular coffee makes people dependent on caffeine; its actual benefits are only appreciated by those who take it just once in a while.
Does coffee really help?
Researchers at the Bristol University in Britain conducted a study involving 379 people; 50 percent of them normally consumed moderate to heavy amounts of caffeine and the rest took little or no caffeine at all.
The volunteers were asked to stay away from the beverage for 16 hours.
Half of study participants were then given a 100mg espresso-sized dose of caffeine, while the other half were given a placebo shot sans any caffeine.
Regular drinkers have headache without coffee
The participants, who were used to taking high amounts of caffeine, reported feeling less alert and complained of a headache after receiving the placebo.
However, those who got caffeine reported no such symptoms. But the post-caffeine levels of alertness in these people were no better than people in the low or non-coffee drinkers group, who were just given the placebo.
This indicates that caffeine only helps in bringing the regular drinkers back to their “normal” level.
Coffee gives no kick, it only helps avoid withdrawal symptoms
The research indicates that caffeine does not give any kick, but it only helps the regular drinkers avoid withdrawal symptoms. People, who regularly take coffee, usually complain of lethargy and dizziness if they skip it one time.
“Although frequent consumers feel alerted by caffeine, especially by their morning tea, coffee or other caffeine-containing drink, evidence suggests that this is actually merely the reversal of the fatiguing effects of acute caffeine withdrawal,” said Bristol University’s Professor Peter Rogers, and colleagues.
Though coffee is long known to be a stimulant that prompts the release of adrenaline, latest research suggests that it works only for people, who are not dependent on it for their normal functioning.
So, getting a boost from caffeine is only possible if you do not take it too often. Regular drinkers get no kick from a cup of coffee; it only helps them to deal with their dependence on caffeine.
