Scientists has shown that drinking water at 37°F (3°C) caused a 5% increase in the number of calories burned, this was considered to be a minimal increase, as cold water’s effect on how many calories you burn was expected to be higher .
Thus, the researchers doubted cold water’s ability to aid weight loss.
What’s more, another study analyzed whether the body would burn additional calories warming ingested water from 59°F (15°C) to 98.6°F (37°C) .
Thereby, about 40% of the thermogenic effect of drinking cold water was attributed to warming the water from 71.6°F to 98.6°F (22°C to 37°C) and only accounted for about 9 calories burned.
Independent of water’s temperature — they considered its effect on metabolism to be significant .
Considering hot or cold water over the other, there isn’t enough evidence to confirm or reject either belief.
Drinking water provides numerous health benefits — whether it’s hot or cold. However, drinking it first thing in the morning is intake of Water.
