Ultimately, the role of a good water bottle is to help you stay hydrated and it’s worth remembering that our body cells need water to function properly.
"Mild dehydration can lead to lightheadedness, cramps, dizziness, reduced motor function and low energy," said Hasoon. "Severe dehydration can lead to much worse outcomes including heat-stroke, loss of consciousness and, in some extreme cases, death."
Drinking enough water while you’re working out is particularly important, Hasoon added. "Given that workouts are usually high intensity, technically demanding and can involve heavy weights, any amount of physical activity puts us in a position where we could severely injure ourselves if we don’t stay sufficiently hydrated, so I advise always having your water bottle with you when exercising."
If you find that you do get dehydrated sometimes, whether that’s due to working out hard or just not drinking enough, then you could consider adding electrolyte powders or tablets to your water bottle. Electrolytes, such as sodium, potassium, magnesium and calcium, are needed to help your body maintain fluid balance, muscle and nerve function, regulate blood pressure, among many more things. Dehydration can lead to electrolyte imbalance so it’s something you should take seriously.
