A couple of days ago, I wrote, “Two Cups of Water First Thing Each Morning,” which is about how I start my day by drinking water.
Brenda Marie Fluharty made a comment that got me wondering about drinking room temperature vs. drinking cold water. So, I did some research about the pros and cons of each. Here is what I found.
I knew that drinking water first thing in the morning is widely touted as being a good thing. And in an unscientific way, folks who commented on my post also confirmed this. One reason for this is that after hours of sleep, your body becomes dehydrated; replenishing with water can jump-start your metabolism, improve cognitive function, support digestion, and boost overall energy levels. Most sources recommend 8–16 ounces (about 250–500 ml) of water immediately upon waking for optimal benefits. You can check out Drinking Water In The Morning for more details.
Now, when it comes to room temperature vs. cold water:
- Room temperature water may be easier on your digestive system, can promote better hydration (since it’s absorbed more efficiently), and is gentler for those with sensitive stomachs, teeth, or throats. It can also support metabolism, aid circulation, and stimulate digestion right after waking up. Many health sources recommend room temperature (or slightly warm) water in the morning, especially for rehydrating after sleep.
- Cold water is not harmful and might be more refreshing for some, particularly after a workout or in hot weather, but it can cause blood vessels in the digestive tract to constrict, which may slightly slow digestion. Cold water may provide a small boost in alertness by stimulating adrenaline, but for morning rehydration and digestive support, room temperature water tends to be favored.
What does this all mean:
Drinking water first thing in the morning is good for you. Room temperature (or slightly warm) water is often considered the best choice for morning hydration because it is gentler on digestion and supports natural metabolic processes, but what matters most is that you hydrate consistently -regardless of the temperature you prefer.
For me, I will be leaving water out the night before, and drinking it at room temperature. Case Closed.
