Many believe that consuming cold water can help burn additional calories daily, but sadly that is a myth and there doesn’t seem to be any evidence around the idea that an individual’s body produces more energy to heat up water back down to its regular temperature.
In fact, past research has revealed that the number of calories that are burned (in and around 4 to 7 calories each glass of cold water) is far too small to even make a difference when it comes to weight loss.
Having said that, there is a silver lining (or two) for those who consume cold water.
As per Jacqueline Schaffer, MD, consuming colder water helps to heighten blood circulation, specifically on the surface of a person’s skin. This promotes the glowing skin that many wish they could achieve, (and maybe now can thanks to this cold-water tip!)
If that doesn’t convince you to drink up your ice water, maybe this will: studies have found that cold water while exercising also lowers one’s chances around dehydration, making you feel less tired, which results in a longer workout (that could ultimately lead to weight loss). The factor behind this is that a person’s core body temperature is kept cool, thanks to the cold water.
Still, Pressform reported that dehydration is not something anyone should fluff off in general. Regardless of whether you are drinking cold water or not, the most important thing is to drink water in general, to avoid dehydration overall; especially on these hotter summer days. Dehydration can cause dizziness, headaches, muscle cramps, and fatigue. It can also cause a person’s metabolism to decrease, and create an inability to take out waste.
So, what’s the lesson here? Cold, room temperature, or a bit hotter than normal; drink up that water! It’s good for you, and for your body.
