12 Daily Habits That Harm Our Health Little by Little

8. Washing your hands with hot water

Various studies have confirmed that hot and cold water are equally effective at killing germs and removing bacteria from our hands. According to these studies, whether it was 38°C or 16°C, water temperature didn’t play a vital role in reducing bacteria. Furthermore, it has been proven that cold water is actually healthier for our hands than hot water.

While it is known that hot water kills bacteria, there is a wrong perception about that. Hot water doesn’t kill bacteria — scalding and nearly boiling water does, which is why medical instruments are boiled in order to be sterilized. Given that washing your hands with boiling water isn’t an option, using cold water is by far the better alternative. Why? Because washing your hands with warm water will soften your skin, making your hands more vulnerable to germs.
