Many people rely on a jolt a caffeine to get them through the day. Caffeine comes to us in many accessible and tasty forms, such as coffee, tea, and chocolate, and even in more to-the-point forms like energy drinks and caffeine pills. As beneficial as caffeine may seem in keeping us awake, intense caffeine usage has also raised some eyebrows in the medical world. This article looks at how caffeine is positively and negatively affects our bodies.
Chemically, caffeine works on our bodies as a cardiac stimulant and mild diuretic. This means that is useful in making us feel alert, but it can also cause dehydration. Although it edits the function of many different hormones, caffeine significantly affects the uptake of adenosine. When your brain absorbs the hormone adenosine, it is prompted to become drowsy, causing you to sleep. It slows down the nerve cells and allows for more oxygen to come into the brain.
Drinking coffee and other sources of caffeine barriers the adenosine receptors in our brains. Instead, caffeine builds to the receptors, hindering the uptake of the hormone and actually speeding up the nerve cells. This also contributes to the constricting of blood vessels. Some headache medications rely on this characteristic of the chemical to help relieve head pressure.
When the rest of your body sees what caffeine is doing in your brain, it stimulates a sort of fight-or-flight response. Your pituitary glands release adrenaline, which leads to dilated pupils, faster heart rate, increased blood pressure, and tense muscles. Generally, this makes you feel excited, alert, and ready to face your day.
While caffeine appears to have positive short-term effects, it can have negative long-term effects on your body. After the rush of adrenaline wears off, you can be left feeling tired and depressed. Of course, most people then consume more of this substance, which again pumps up your body, only to leave it in a downward spiral several hours later. Also, adenosine blockage causes a lack of sleep, so that you need more caffeine to get you alert in the morning. The cycle continues to wear your body down more and more.
If you are pregnant or breastfeeding-feeding, many doctors recommend that you cut down on your caffeine eye. Some studies have shown that excessive caffeine leads to miscarriage. Because you and your unborn baby are so closely connected, the chemical can pass directly from your bloodstream into your child. This can make your baby have an elevated heart rate and inability to sleep as well.
Overall, it seems like your best bet is to enjoy caffeine in moderation. For more advice on health topics such as exercise ideas, healthy recipes, and tips to enjoy your life to the fullest, check out the interesting and informative Health Directory today.
