In the hotter months, it is natural to want to freshen up by drinking very cold water. You might think this will cool you down, but in reality, it may not be a good idea to drink extremely cold water while it is really hot.
Also, we have apparently been drinking water wrong all our life! You’re not supposed to drink while standing up!
Drinking cold water in hot weather can send your body into shock and your stomach will go hypothermic. To compensate, your body will take the warm blood from your hands, feet and head and send it to your stomach.
If you want to hydrate quickly when it is hot, it is best to drink room-temperature water, as this will not shock your body.
