Your body has to work overtime to warm that cold water. That uses calories and energy. Sounds good for weight loss, right? Not so fast.
That energy diversion means less fuel for your muscles and brain. You might feel a tiny energy slump after downing a cold glass. It’s like your body saying, “Hey, I was busy digesting. Don’t expect a sprint.”
Warm water, in contrast, can actually give you a gentle energy boost. It’s hydrating without the drama. Your mitochondria—the powerhouses of your cells—appreciate the stability.
