How Does Caffeine Affect The Body?
Caffeine is a central nervous system stimulant. It works by blocking the action of adenosine, a brain chemical that makes you feel tired. When adenosine binds to its receptors, it slows down nerve cell activity. Caffeine prevents adenosine from binding to its receptors, resulting in increased activity in the brain.
Caffeine also increases the release of other neurotransmitters such as dopamine and norepinephrine. These neurotransmitters are associated with increased alertness and improved mood.
The effects of caffeine vary from person to person. Some people are more sensitive to its effects than others. Factors that can influence how sensitive you are to caffeine include:
-Whether you’ve eaten recently
-How frequently you consume caffeine
-Other medications you’re taking
How Long Does Caffeine Stay In Your System?
The half-life of caffeine is the time it takes for your body to eliminate one-half of the caffeine you consume. Because everyone metabolizes caffeine differently, theHalf-life of caffeine can range from 1.5 to 9.5 hours. The half-life of caffeine is also affected by how much coffee you drink, how quickly you drink it, whether you ate anything with it, and your individual metabolism.
Assuming an average half-life of 5 hours for a 150 lb person, here’s how long it would take for the body to eliminate the caffeine from 8 oz of coffee:
Processing time: 1 hour
Elimination time: 4 hours
Total time: 5 hours
What Are The Side Effects Of Caffeine?
While caffeine is generally safe, there are some side effects that you should be aware of. These include:
Can Caffeine Cause Anxiety?
While 8 oz of coffee has around 95 mg of caffeine, it’s the cup size that matters most. The more coffee you drink, the more caffeine you consume. If you’re prone to anxiety, it’s best to stick to 1-2 cups per day.
Can Caffeine Cause Insomnia?
While most people know that caffeine is a naturally occurring stimulant, many are unaware of just how much caffeine is in 8 oz of coffee. According to the Mayo Clinic, a cup of coffee can contain anywhere from 95-200 mg of caffeine. For people who are sensitive to caffeine, this can be enough to cause insomnia and other sleep problems. If you’re struggling with insomnia, cutting back on caffeine may help you get the rest you need.
Can Caffeine Cause Dehydration?
If you enjoy coffee, you might wonder about the amount of caffeine in 8 oz of coffee. Although caffeine is a diuretic and can cause dehydration, you would need to consume about 250 mg of caffeine to have this effect. An 8 oz cup of coffee has about 95 mg of caffeine.
