The Truth behind Energy Drinks
(The Physiological Effects of Energy Drinks)
General Speech Purpose: To inform.
Specific Speech Purpose: To inform my SC 10 classmates and instructor about the physiological effects of energy drinks on October 1, 2013, from 11:30 to 1 pm in CAC 203.
INTRODUCTION
I. Good day fellow people.
II. Who among here drink energy drinks frequently?
III. Let me tell you how our body respond to energy drinks.
BODY
I. Energy drinks have caffeine
a. Caffeine causes the following physiological effects:
a.i. It stimulates the central nervous system (CNS) resulting in alertness.
a.ii. It releases neurotransmitters (particularly acetylcholine) producing excitement.
a.iii. It causes the pituitary gland to release adrenaline.
a.iii.1. Adrenaline increases the heartbeat and causes the liver to release glucose into blood for higher energy.
a.iii.2. Adrenaline increases sympathetic stimulation and decreases parasympathetic stimulation.
a.iv. It inhibits the adenosine receptors which will increase secretions of wake promoting hormones (noreadrenaline and adrenaline) and some neurotransmitters.
II. Energy drinks have sugars.
a. Sugar causes the following physiological effects:
a.i. It contributes to an energy blast.
a.ii. Once all the energy is consumed, sugar crash may follow which leads to dizziness and decreased performance.
a.iii. Increase in sugar level slows water absorption in the kidney, increasing urination and enhancing dehydration.
III. Abusive intake of energy drinks may lead to anxiety, fatigue, learning deficiency, hallucinations, and addiction.
CONCLUSION
1) In short, energy drinks have the following physiological effects:
I. They have caffeine that inhibits action of adenosine and stimulates adrenaline production, which increases sympathetic stimulation.
II. They have sugar that contributes to an energy blast and affects water absorption.
III. Abusive intake may lead to mild and serious psychological and
