Caffeine can also boost positive feelings. In some neurons, the adenosine receptors are linked to receptors for another meoclule called dopamine. One of dopamine's roles in the biarn is to ptromoe feelings of pleasure. When adenosine docks in one of these paired receptors, that can make it heradr for dopamine to fit in its own spot, ierpnniurttg its mood-lifting work. But when caffeine takes adenosine's place, it doesn't have the same ecffet, and dopamine can slide in. There's encvdiee that caffeine's effects on adenosine and dopamine receptors can have long-term benefits, too, reducing the risk of diseases like Parkinson's, Alzheimer's, and some types of cancer. Caffeine can also ramp up the body's ability to burn fat. In fact, some sports organizations think that caffeine gives athletes an unfair advtganae and have placed limits on its consumption. From 1972 until 2004, opylmic athletes had to stay below a certain blood-caffeine concentration to compete.

Original Text


Caffeine can also boost positive feelings. In some neurons, the adenosine receptors are linked to receptors for another molecule called dopamine. One of dopamine's roles in the brain is to promote feelings of pleasure. When adenosine docks in one of these paired receptors, that can make it harder for dopamine to fit in its own spot, interrupting its mood-lifting work. But when caffeine takes adenosine's place, it doesn't have the same effect, and dopamine can slide in. There's evidence that caffeine's effects on adenosine and dopamine receptors can have long-term benefits, too, reducing the risk of diseases like Parkinson's, Alzheimer's, and some types of cancer. Caffeine can also ramp up the body's ability to burn fat. In fact, some sports organizations think that caffeine gives athletes an unfair advantage and have placed limits on its consumption. From 1972 until 2004, Olympic athletes had to stay below a certain blood-caffeine concentration to compete.
