Those taking part in the challenge, claim that their energy has been boosted, their skin is 'glowing' and that any bloating is gone. However, there is one obvious and immediate drawback - constantly need to go to the toilet.
I tried drinking 1 Gallon (3.7L) of water every day for 30 days 💧 #thegallonchallenge
Other, more long-term problems can include flushing out electrolytes and 'hyperhydration' or 'water intoxication' which can cause symptoms such as fatigue, disorientation, headache, nausea and vomiting.
There is also hyponatremia, which can happen when sodium levels fall below 135 millimoles per litre. At it's most extreme levels 'water intoxication' can lead to seizures, brain damage, comas or even death.
That being said the water that you also consume as part of your food also counts towards the gallon a day so if you are taking part in the challenge please remain vigilant and do so sensibly.
