INTRODUCTION Caffeine is a natural component of chocolate, coffee and tea, and is used as an added energy boost in most colas and energy drinks. It’s also found in diet pills and some over-thecounter pain relievers and medicines. Caffeine is the most commonly consumed psychoactive drug in the entire world. Medically, caffeine is useful as a cardiac stimulant and also as a mild diuretic - it increases urine production. Recreationally, it is used to provide a "boost of energy" or a feeling of heightened alertness. College students often use it to stay awake while cramming for finals and drivers use it to push through to their destination. Many people feel as though they "cannot function" in the morning without a cup of coffee to provide caffeine and the boost it gives them. In doses of 100-200 mg. caffeine can increase alertness, relieve drowsiness and improve thinking. At doses of 250-700 mg/day, caffeine can cause anxiety, nervousness, hypertension, and insomnia. It can curiously enough make it more difficult to lose weight because it stimulates insulin secretion, which reduces serum glucose, which increases hunger. It's important to know that caffeine is an addictive drug. Among its many actions, it operates using the same mechanisms that amphetamines, cocaine, and heroin use to stimulate the brain.

Relatively speaking, caffeine's effects are milder than amphetamines, cocaine and heroin, but it is manipulating the same channels in the brain, and that is one of the things that give caffeine its addictive qualities. If you feel like you cannot function without it and must consume it every day, then you may be addicted to caffeine. Caffeine and Adenosine Adenosine is found in every part of the body, but it has special functions in the brain. As adenosine is created in the brain, it binds to adenosine receptors. The binding of adenosine causes drowsiness by slowing down nerve cell activity. In the brain, adenosine binding also causes blood vessels to dilate, most likely to let more oxygen in during sleep. Caffeine readily crosses the blood–brain barrier that separates the bloodstream from the interior of the brain. Once in the brain, the principal mode of action is as a nonselective antagonist of adenosine receptors. The caffeine molecule is structurally similar to adenosine, and binds to adenosine receptors on the surface of cells without activating them (an "antagonist" mechanism of action). Therefore, caffeine acts as a competitive inhibitor. Instead of slowing down because of the adenosine's effect, the nerve cells speed up. Caffeine also causes the brain's blood vessels to constrict, because it blocks adenosine's ability to open them up. This effect is why some headache medicines like Anacin contain caffeine -- if you have a vascular headache, the caffeine will close down the blood vessels and relieve it.

So, now you have increased neuron firing in the brain. The pituitary gland sees all of this activity and thinks some sort of emergency must be occurring, so it releases hormones that tell the adrenal glands to produce adrenaline (epinephrine). Adrenaline is the "fight or flight" hormone, and it has a number of effects on your body: • Your pupils dilate. • Your breathing tubes open up (this is why people suffering from severe asthma attacks are sometimes injected with epinephrine). • Your heart beats faster. • Blood vessels on the surface constrict to slow blood flow from cuts and also to increase blood flow to muscles. • Blood pressure rises. • Blood flow to the stomach slows. • The liver releases sugar into the bloodstream for extra energy. • Muscles tighten up, ready for action. This explains why, after consuming a big cup of coffee, your hands get cold, your muscles tense up, you feel excited and you can feel your heart beat increasing. Caffeine and Dopamine Caffeine also increases dopamine levels in the same way that amphetamines do. Dopamine is a neurotransmitter that activates pleasure centres in certain parts of the brain. Heroin and cocaine also manipulate dopamine levels by slowing down the rate of dopamine reabsorption. Obviously, caffeine's effect is much lower than heroin's, but it is the same mechanism. It is suspected that the dopamine connection contributes to caffeine addiction. You can see why your body might like caffeine in the short term, especially if you are low on sleep and need to remain active. Caffeine blocks adenosine reception so you feel alert. It injects

adrenaline into the system to give you a boost. And it manipulates dopamine production to make you feel good. The problem with caffeine is the longer-term effects, which tend to spiral. For example, once the adrenaline wears off, you face fatigue and depression. So what are you going to do? You consume more caffeine to get the adrenaline going again. As you might imagine, having your body in a state of emergency all day long isn't very healthy, and it also makes you jumpy and irritable. The most important long-term problem is the effect that caffeine has on sleep. Adenosine reception is important to sleep, and especially to deep sleep. The half-life of caffeine in your body is about six hours. That means that if you consume a big cup of coffee with 200 mg of caffeine in it at 3:00 p.m., by 9:00 p.m. about 100 mg of that caffeine is still in your system. You may be able to fall asleep, but your body will probably miss out on the benefits of deep sleep. That deficit adds up fast. The next day you feel worse, so you need caffeine as soon as you get out of bed. The cycle continues day after day. Once you get in the cycle, you have to keep consuming the drug. Even worse, if you try to stop consuming caffeine, you get

very tired and depressed, and you get a terrible, splitting headache as blood vessels in the brain dilate. These negative effects force you to run back to caffeine even if you want to stop. Tolerance and withdrawal Because caffeine is primarily an antagonist of the central nervous system's receptors for the neurotransmitter adenosine, the bodies of individuals that regularly consume caffeine adapt to the continuous presence of the drug by substantially increasing the number of adenosine receptors in the central nervous system. First, the stimulatory effects of caffeine are substantially reduced, a phenomenon known as a tolerance adaptation. Second, because these adaptive responses to caffeine make individuals much more sensitive to adenosine, a reduction in caffeine intake will effectively increase the normal physiological effects of adenosine, resulting in unwelcome withdrawal symptoms in tolerant users. Caffeine tolerance develops very quickly, especially among heavy coffee and energy drink consumers. A reduction in serotonin levels when caffeine use is stopped can cause anxiety, irritability, inability to concentrate, and diminished motivation to initiate or to complete daily tasks; in extreme cases it may cause mild depression. Together, these effects have come to be known as a "crash". Careful research conducted by the department of psychiatry and behavioural sciences at Johns Hopkins University School of Medicine shows that low to moderate caffeine intake (as little as one 14-ounce mug per day) can quickly produce withdrawal symptoms. Withdrawal symptoms — possibly including headache, irritability, an inability to concentrate, drowsiness, insomnia and pain in the stomach, upper body, and joints may appear within 12 hours after discontinuation of caffeine intake, peak at roughly 48 hours, and usually last from one to five days, representing the time required for the number of adenosine receptors in the brain

to revert to consumption.

Caffeine Intoxication and Overdose An acute overdose of caffeine usually in excess of about 250 mg, dependent on body weight and level of caffeine tolerance, can result in a state of central nervous system overstimulation called caffeine intoxication (DSMIV 305.90), or colloquially the "caffeine jitters". It may include restlessness, fidgetiness, nervousness, excitement, euphoria, insomnia, flushing of the face, increased urination, gastrointestinal disturbance, muscle twitching, a rambling flow of thought and speech, irritability, irregular or rapid heart beat, and psychomotor agitation. In cases of much larger overdoses, mania, depression, lapses in judgment, disorientation, disinhibition, delusions, hallucinations, and psychosis may occur, and rhabdomyolysis (breakdown of skeletal muscle tissue) can be provoked. These symptoms can cause significant social and occupational disturbances. Caffeine intoxication is rarely fatal, although 5,000-10,000 mg of caffeine can actually kill you. Fortunately,

most people won’t ever ingest this much caffeine accidentally it would take between 30 and 60 cups of coffee in one morning. Overuse In large amounts, and especially over extended periods of time, caffeine can lead to a condition known as Caffeinism. Caffeinism usually combines caffeine dependency with a wide range of unpleasant physical and mental conditions including nervousness, irritability, anxiety, tremulousness, muscle twitching (hyper-reflexia), insomnia, headaches, respiratory alkalosis, and heart palpitations. Furthermore, because caffeine increases the production of stomach acid, high usage over time can lead to peptic ulcers, erosive esophagitis, and gastroesophageal reflux disease. Caffeine may also increase the toxicity of certain other drugs, such as paracetamol. There are four caffeine-induced psychiatric disorders recognized by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition: caffeine intoxication, caffeine-induced anxiety disorder, caffeine-induced sleep disorder, and caffeine-related disorder not otherwise specified (NOS). Caffeine-induced sleep disorder Caffeine-induced sleep disorder is a psychiatric disorder that results from overconsumption of the stimulant caffeine. The specific criteria for this disorder in the fourth axis of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) include that there must be a significant inability to sleep which is caused entirely by the physiological effects of caffeine as proven by an examination; if sleeping issues can be accounted for due to a breathing-related sleep disorder, narcolepsy, or another mental disorder, then caffeine-induced sleep disorder is not the cause. This condition causes a notable impairment in functioning in sufferers Although the number of symptoms due to caffeine consumption are many, however on the basis of importance, severity and

relation to working habits of the BPO employees we have selected- Sleep Disturbances, Headache & Irritability.

REVIEW OF LITERATURE Although a number of studies on caffeine addiction have been conducted in the past, the following two appeared to be significant with respect to our study. The first study done by the University of the Philippines (UP) Population Institute is about prevalence of caffeine consumption among BPO workers. The study, entitled Lifestyle and Reproductive Health Issues of Young Professionals in Metro Manila and Metro Cebu (), focused on the profile and lifestyle of young workers in the call center and non-call center industries in Metro Manila and Metro Cebu. The results obtained were: ○ Highly-caffeinated drinks like coffee and tea are a staple of BPO workers diets, which are provided by management through establishment of Vendor machines, free of cost. ○ In all, 2/3 of young workers drink coffee daily, but call center workers drink more coffee that their non-call center counterparts (2.3 cups a day for call center workers vs 1.7 cups for the latter). ○ More call center workers also consume tea (1/4 of respondents), compared to non-call center workers (only 1/5). ○ The study also revealed that half of young workers drink soda daily, at an average of 1.5 bottles/cans a day, regardless of group. ○ However, energy drinks are not as popular: only 15% of young workers drink energy drinks daily, the study found out. The second was a study conducted by American Academy of Pediatrics (Charles P. Pollak, 2003) to study the Caffeine consumption and its effect on sleep patterns in teenagers. A total of 191 students participated. Caffeine intake ranged between 0 and 800 mg/d. Mean use over 2 weeks ranged up to 379.4 mg/d and averaged 62.7 mg/d. According to the study, higher caffeine intake in general was associated with shorter nocturnal sleep duration, increased wake time after sleep onset, and increased daytime sleep. Regardless of whether caffeine use disturbed sleep or was consumed to counteract the daytime

effect of interrupted sleep, caffeinated detectable pharmacologic effects.

IMPLEMENTATION The entire research study was done on 2 BPO firms in IndoreTelecommunications and First Source. A Qualitative protocol was used which involved data collection through a detailed objective-questionnaire. The questionnaire was distributed in random manner through the HR manager of the firms to BPO workers. Due to the concerns of the HR about compromise of their office time, they were given 2 days to fill the questionnaires. The Instrument for data collection, in the form of a ‘Structured Questionnaire’, consisted of the following sections: 1. 2.

3.

4. 5.

Demographic aspects included name, age, gender, working hours and Alcoholic & Smoking nature. Caffeine Consumption was assessed by objective questions about choice of beverage, size of cup and interval between drinks. (Q1-5) Sleep disturbance suspected to be caused due to caffeine was assessed mainly by subject’s perception of his quality of sleep along with the duration of sleep. (Q6-10) Headache problems were asked directly. (Q11) Irritability as a part of the mood disorders suspected to be caused by Caffeine was assessed by 8 part questionnaire modified and adopted from The Irritability Questionnaire by K.J. Craig et al. 2008 (Kevin J. Craig, 2008). (Q12)

A copy of Questionnaire is given in the Appendix. The responses thus obtained were then compiled, processed and analysed to arrive at the opinions on various issues.

SCORING CRITERIA As already mentioned the questions were divided in four sections. Most questions had three responses. Maximum points were allotted to exaggerated responses and associations, whereas minimum points were allotted to responses depicting least degree of association. The score of each section was then added to attain the total score. RESPONSE

CONCLUSION • More than 50% of the BPO employees were found to have moderate intake of Caffeine. And as many as 35% were heavy consumers of Caffeine. •

•

•

61% of subjects are habituated to drink a Caffeine containing beverage daily. According to this study 16% of prevalence of Sleep disturbance, 50% of Irritability may be attributed to high Caffeine consumption. Also Heavy consumers of Caffeine were found to have significantly more complaints (80%) of headache as compared to Mild consumers (50%).

DISCUSSION Caffeine is the most commonly consumed psychoactive drug in the world. It produces tolerance very quickly which is responsible for its various withdrawal symptoms. Out of various side-effects of Caffeine we have selected to study- Sleep disturbances, headache and Irritability. The aim of our study was to find out the overall prevalence of caffeine consumption, and to explore the relationship between excess caffeine consumption and the above mentioned symptoms. It was a cross sectional study done in a randomly selected sample of 100 BPO employees 20 to 50 years old working at Telecommunications & First Source, Indore. Data was collected via a semi-structured questionnaire which was then compiled and analyzed. According to the study 57% of the BPO employees were found to have moderate intake of Caffeine and as many as 35% were heavy consumers. This might be ascribed to free vending machines provided by the management. Also in the study we were able to correlate Sleep Disturbance (16%), Irritability (50%) with Caffeine consumption. 80% of Heavy consumers were found to have complaints of Headache as compared to 50% of Mild consumers. In comparison to a previous study- “Lifestyle and Reproductive Health Issues of Young Professionals in Metro Manila and Metro Cebu” conducted by the University of the Philippines (UP) Population Institute which stated that 2/3rd of BPO employees consumed Caffeine containing beverage on a daily basis, our results of 61% correlate well, considering the demographic and geographic limitations.

RECOMMENDATIONS • The BPO workers and all who have moderate to heavy intake should be made aware of the ill-effects of long term caffeine consumption. • DRINK LOTS OF WATER, LOTS AND LOTS OF WATER. Get yourself a replacement drink, it could be water, juice, decaf - just something to get when the urge for a cup sneaks in. •

Herbal Tea can also be used a good alternative to Caffeine containing beverages.

•

Workers should avoid drinking Caffeine beverage at least 4hrs prior to sleeping, and get adequate sleep of 6-8 hrs.

• They should indulge in relaxation activities such as Meditation, Exercise. •

The BPO management should have provisions for De-Caffeinated beverages, which will improve the working capacity of their employees along with a healthy life style.
