Sunday, July 17, 2016


Caffeine is used by millions of people every day to increase wakefulness, alleviate fatigue, and improve focus. However, there are serious side effects of drinking too much coffee. Here are 12 dangers of partial and total caffeine overdose, in order from the first symptoms to be exhibited to the severe, later stage ones.




1. Increased Heartbeat  - Caffeine acts as a stimulant on the central nervous system, increasing your heart rate. This can be expected as soon as 10 minutes after ingesting.

2. Jitters/Restlessness - Caffeine stimulates hormones, such as adrenaline, sending your body into jitters and tremors.

3. Anxiety - The stimulant effects on the body from caffeine, such as increased heart rate, increased adrenaline hormones, and heightened senses, can combine to produce an overwhelming sensation in some people, making them feel anxious.

4. Muscle Twitches and Spasms - A high volume or prolonged use of caffeine in the body can cause the muscles to cramp or move erratically.

5. Diuresis - Caffeine increases the need to urinate because it increases blood flow through the kidneys and dilates the blood vessels, making the kidneys produce more waste.

6. Gastrointestinal Disturbance - Caffeine acts as a laxative by increasing contraction in the small and large intestinal muscles. This can cause predigested food to move into the intestine, triggering stomach cramps.

7. Dehydration - Persistent diarrhea and urination can lead to dehydration, which can upset the bodys fluid balance, depleting it of the water, vitamins, and minerals it needs to order to function.

8. Insomnia - Caffeine inhibits the activity of a neurotransmitter called Adenosine, which is one of your brains natural tranquilizers. It puts you to sleep when levels are high enough. By inhibiting Adenosine activity, caffeine inhibits your ability to fall asleep.

9. Headaches - The combination of diuretic and stimulant pulsing through the body can cause the receptors in the brain to become overloaded, leading to a headache.

10. Hallucinations - Hallucinations are believed to occur when an overdose of caffeine causes the body to become stressed. This is a result of high adrenaline levels.

11. Addiction - Caffeine addiction or dependence begins because caffeine first creates the alert feeling that coffee drinkers crave, and later becomes a chemical that the body needs to prevent withdrawal symptoms such as headaches, lethargy, and depression.

12. Increased Blood Pressure - Caffeine causes your adrenal glands to release more adrenaline, which causes your blood pressure to increase.
