After an arduous workout, nothing is more refreshing than sipping on a glass of icy tap water. In addition to hydrating the body and boosting dental health (by washing away food deposits and delivering fluoride) without any additional empty calories, drinking ice water has the added perk of empowering the body to burn more calories than sipping on a room-temperature beverage.
Research published in the International Journal of Obesity indicated that drinking cold water has a thermogenic effect on adults (a reaction to food consumed that increases a metabolic rate by encouraging the body to produce energy or heat resulting in an expenditure of calories). The thermogenesis state triggered by sipping ice water can greatly increase the resting energy expenditure (REE) and the number of calories burned when a body is at rest (http://www.nature.com/ijo/journal/v35/n10/full/ijo2011130a.html). The hypothesis is that sipping ice water will rapidly cool the upper gastrointestinal tract, and raise the REE rate, forcing the body to burn excess calories.
Individuals should know that while sipping ice water is smart, chewing on the cubes can cause dental problems. The reason? Water can exist in three states; liquid, gas (vapor or steam) and solid (in the form of ice). Although water is densest in its liquid state (which is the reason ice floats on water), frozen molecules are suspended in mid action and the liquid will convert to a tough solid, AKA ice. Chewing on ice can contribute to excessive wear and tear on teeth, damage tooth enamel, harm dental fillings and increase the odds of cracking the tooth itself. Additionally, individuals with sensitive teeth may not be able to handle the sensation of the icy temperature on exposed nerves.
Coffee or Tea
There is no arguing that professional athletes can benefit from sports drinks, but for the average Jane or Joe exercisers, the health benefits and pick-me-up effects associated with the drinks are typically negated by the risks to dental health presented by the higher acid and sugar levels present. Experts suggest that a plain caffeinated beverage such as tea or coffee is a much smarter idea. According to Elizabeth Applegate (Senior Lecturer, Department of Nutrition Director of Sports Nutrition, Intercollegiate Athletics) a low-cal drink with 100 grams of caffeine will provide the weekend warrior with enough of an energy boost minus the risks of processed beverages (http://www.huffingtonpost.com/2012/06/04/sports-drink-alternative_n_1557221.html?ref=healthy-living#s=1047773).
Aside from the energy perk, there are different dental health benefits linked to various, natural sources of caffeine. Coffee has been scientifically shown to reduce the odds of developing cavities, black tea is known for having naturally high levels of fluoride and green tea (rich with antioxidants, polyphenols and catechins) has been shown to fight cancer, prevent heart disease and can improve oral health by fighting gum disease. The key to reaping the health benefits of any type of caffeine is to keep it simple and avoid adding empty calories in the form of artificial sweeteners or sugar.
