Many of us learned in history class how vitamin C prevents scurvy, a now-rare condition once dangerous to sailors. Today, the vitamin is mostly associated with boosting the immune system or in fighting the common cold [source: MedlinePlus].

That means those who consume enough, through a supplement or from fresh citrus fruits and juices, can better withstand weather that leads to heat exhaustion.
