The Negative Effects of Ice Water on Your Body
6. Slows Heart RateÂ
Drinking ice water can cause your heart rate to drop. This is because the vagus nerve, which runs down the back of your neck, is affected by a sudden ingestion of ice-cold water. As an emergency measure, your heart rate slows down until your body temperature reaches equilibrium once again.
7. Irritates ThroatÂ
Just as a cold winter’s day can give you a runny nose and block up your sinuses, ice-cold water creates the same bodily response. In other words, your body creates mucus as a natural humidifier to warm any ingested cold air or liquid. The difference is that in the case of ice water, this bodily response is unneeded, and it results in extra mucus accumulating in your pipes, thus making your throat sore.
