Energy drinks consumption has varied effects on the hemodynamic, blood glucose levels, brain functions and memory. The use of energy drinks is pervasive and especially young adults consume it often as binge drinking. The negative health effects of excessive use of energy drinks has been reported in the scientific literature. Often energy drinks are consumed to enhance alertness and cognition improvement. In this trial, the investigators intend to compare the effects of a widely available energy drink brand in the country with the usual black tea with 5gm sugar and milk. The aims of this study is:
The participants will be halved in two groups: control group (consuming tea with 5gm of sugar only) and experimental group (consuming energy drinks only) to acquire data regarding fluctuations in hemodynamic parameters including heart rate (HR) and blood pressure (BP)-systolic and diastolic (SBP and DBP) by measuring them before and after 30 minutes of the consumption of tea with 5gm of sugar or energy drink in control or experimental groups. In addition blood glucose level will be monitored in both the groups via glucometer before and after. Reactions of energy drinks in comparison to tea on their respective groups will also be analyzed by help of a stroop test (where the name of the color itself does not match the ink of the color in which it is printed) for understanding its impact on cognitive strengths and on memory by a minor sequence learning game controlled by time lapse. After these interventions participants will be requested to fill out the questionnaire.
The investigatorsare aiming for a sample size of 76 participants, 38 in each of the two groups.
Data will be entered and analyzed in Statistical Package for the Social Sciences version 20 or above. Mean and SD will be calculated for variables such as age, weight, blood pressure (Systolic and Diastolic) and heart rate, blood glucose and Stroop Test score. For qualitative variables such as sex, co morbidity e.g. heart disease, hypertension, family history will be presented as absolute frequencies and proportions. The hemodynamic parameters will be recorded before and after consumption of energy drinks in the intervention and the control group. Independent samples student t-test will be used to compare mean values of hemodynamic parameter between intervention and control group. Significance level of 5% will be set for the study keeping power at 80%.

|---|---|---|---|
| energy drink arm | Experimental | an open label branded energy drink which contains any one or more of the following ingredients: caffeine, ginseng, taurine |
|
| tea 5gm sugar arm | Active Comparator | the usual easily available black tea with sugar 5 grams, and milk |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| energy drink | Other | An easily available 250 ml branded energy drink will be randomized to the partcipants after informed consent. Before and thirty minutes after drinking the given energy drink the participant cognition, heart rate, blood pressure and blood glucose will be measured. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in systolic and diastolic blood pressure | before and after consumption of the energy drink or the tea both systolic and diastolic blood pressures will be measured as per international guidelines for measuring BP | half hour post consumption |
| Change in heart rate | before and after consumption of the energy drink or the tea heart rate will be measured as per international guidelines | half hour post consumption |
| Change in blood glucose | before and after consumption of the energy drink or the tea blood glucose levels will be measured as per international guidelines | half hour post consumption |
| Change in short-term memory and vigilance | before and after consumption of the energy drink or the tea short term memory functions will be measured using color sequence game. We will use STROOP test to assess vigilance | half hour post consumption |
| Measure | Description | Time Frame |
|---|---|---|
| perceptions and knowledge of participants about energy drinks | simple questions from the participants about the effects and composition of energy drinks | within one hour of consumption of the energy drink or the active comparator |
