Why does cold water wake you up

Water helps metabolize and transport the essential carbohydrates and proteins that you consume every day. Providing your body with water in the morning will help get your metabolism going for the day.

While room temperature water is recommended for optimal digestion , the most important thing is to drink enough water to rehydrate your body in the morning and keep it hydrated throughout the day. Keep a glass of water next to your nightstand so you can literally grab it as you get out of bed. Or, you can pour yourself a glass and have it while you wait for your coffee to finish brewing.

Despite having lighter-colored urine, they were not particularly well hydrated. Conversely, the darker color of your morning urine is not necessarily a sign of dehydration.

However, the effects of mild dehydration can be reversed by reintroducing fluids, and no evidence limits the benefits of rehydration to the early morning 5. Your kidneys are the primary regulators of fluid balance, and they do require water to eliminate waste from your bloodstream 5. If a substance is present in an amount greater than your kidneys can handle, they induce the production of a large volume of urine.

This is called osmotic diuresis and is different from water diuresis, which happens when you drink too much water 1. There are also claims that drinking water boosts skin health. Though severe dehydration can reduce skin turgor and cause dryness, there is a lack of evidence to support this claim 5 , Another widespread opinion suggests that you opt for hot or warm water over cold water when you wake up, as it can soothe your body.
