Without drinking coffee, do you experience a difficult time functioning in the morning? Well, you are not the only one. After all, caffeine is the most frequently used drug, and the most widely accepted as well. As we all know, coffee has caffeine, a natural stimulant that is also found in tea, soft drinks, and chocolate – albeit in tiny amounts. As of now, it is the most frequently used psychoactive substance and is one to be accused of coffee’s addictive substances.
Caffeine has a number of effects in your body. This includes improved performance, metabolism, and mood. Also, caffeine is popular for its effect on your brain since it also improves alertness, concentration, and motivation.
The measure of caffeine depends on the coffee. For example, some coffee has 300 mg of caffeine while others contain just only 30 mg.
However, on average, an 8-ounce cup of coffee only contains 100 mg of caffeine. For most people, this is enough to make them experience notable effects.
Once drank, caffeine kicks in about 30-60 minutes before it can attain its maximal concentration in the blood. The effects could last for a minimum of 3 hours to a maximum of 9 hours, but this still varies on the person.
Once you consume caffeine, this is promptly absorbed by your gut before it goes to your brain. Once it reaches the brain, it will start its stimulating effects on the brain cells. The reason behind this is that the chemical structure of caffeine looks like adenosine, a molecule which gives a relaxing effect in the central nervous system. This permits the caffeine to fit into the adenosine receptors found in the brain, which in turn prevents and hinders the adenosine from bonding to them, thus giving out the feeling of tiredness.
In turn, the receptors that are blocked provoke the discharge of natural stimulants and permit some of them, like dopamine, to act effectively. This now heightens alertness but lowers feelings of tiredness.
In other terms, caffeine prevents your brain cells from giving out signals that you are tired and causes your body to give out other stimulants that heighten their effects.
As mentioned earlier, coffee has some certain health benefits. These include an improved mood, enhanced brain function, metabolism, and performance. But despite these benefits, too much intake of caffeine per day can do more harm than good.
Due to this, experts recommend that you should limit your intake to 400 mg, meaning you should only consume about 4-5 cups of coffee. Also, just to be safe, you should consume no more than 200 mg since this is the safest limit.
Moreover, there are certain individuals that should lower their intake or completely avoid caffeine. For example, people with insomnia and anxiety who consume caffeine can possibly experience jitteriness and heart palpitations.
The bottom line here is coffee and caffeine has addictive properties that may result in dependence. However, you should also take note that addiction is caused by many factors and varies from one person to another.
