Role of cold drinks in our body:
1. All gases are not come out when the cork is opened thus the harmful CO2 enter into the body when we take drinks. Excess amount of NaHCO3 goes to blood and creates systemic alkalosis which causes Kidney diseases, Anxiety, Disturbances in inhalation and other complexities.

"Daily use of even relatively low doses of caffeine (about 100 milligrams a day) results in physical dependence, with abstinence characterized by withdrawal symptoms such as headache, fatigue, depressed mood and difficulty concentrating," Researchers said.

Many factors have been cited as contributors to the rise in obesity: a shift in American eating habits toward more fast food, increased consumption of soft drinks, decreased physical activity and increased inactivity.
Researchers from the University of Cincinnati (UC) have found that eating or drinking sweets may decrease the production of the stress-related hormone glucocorticoid--which has been linked to obesity and decreased immune response. "Glucocorticoids are produced when psychological or physical stressors activate a part of the brain called the 'stress axis,'" said Yvonne Ulrich-Lai, PhD, a postdoctoral fellow in the department of psychiatry.
"These hormones help an individual survive and recover from stress, but have been linked to increased abdominal obesity and decreased immune function when produced in large amounts."Finding another way to affect the body's response to stress and limit glucocorticoid production could alleviate some of these dangerous health effects."
Spurred by the rising rate of obesity among American youth and the increasing availability of high-calorie, low-nutrient products on school grounds, a new report by the Institute of Medicine proposes a set of nutritional standards for "competitive" foods and drinks available in schools.

They should also drink at regular intervals (every 20 minutes) during the course of the activity and after the activity ends.
"The alarming increase in childhood obesity rates has galvanized parents and schools across the nation to find ways to improve children's diets and health for making sure that all foods and drinks available in schools meet nutrition standards is one more way schools can help children establish lifelong healthy eating habits."In addition, sports drinks should be available only to students engaged in an hour or more of vigorous athletic activity, at the discretion of coaches.
