Starting your day with a glass of cold water can kickstart your metabolism. Drinking cold water first thing in the morning can help to wake up your digestive system and provide a gentle boost to your energy levels, as your body works slightly harder to warm the water to body temperature.
Consuming about 8 ounces (240 ml) of cold water upon waking helps rehydrate your body after a night’s sleep. This simple habit can improve alertness and cognitive function, setting a productive tone for the day.

4. Why You Should Avoid Cold Water After Meals

While cold water has its benefits, drinking it immediately after meals is not one of them. Cold water can solidify fats from the food you have just eaten, making it harder for your body to digest and absorb nutrients properly. This can lead to digestive discomfort and bloating.
For optimal digestion, it’s best to consume warm or room temperature water after meals. This helps maintain a smooth flow of digestive processes and supports nutrient absorption, ensuring your body gets the most out of the food you consume.
