What seems like common sense in the gym can sometimes fall by the wayside after you leave. Staying hydrated, though, can help you stay healthy—the trick is doing it right. Swap out the sweetened sports drinks for filtered water, says Dr. Eliaz, because sugary drinks can “spike glucose levels, which can suppress immunity over time and make you more susceptible to colds and flus.” You can add extra no-sugar electrolyte packets or tablets to your water to get an extra boost, but the key to staying well-hydrated is drinking before you are actually thirsty. Remember that.
