You haven’t gained any weight, so why does the band you’ve worn on your finger forever suddenly feel two sizes too small? Chances are, your sudden sausage fingers are caused by water retention, which can happen when you load up on salt.
Feel like you just ate a bunch of cotton balls? Yup, it might be salt’s fault. After loading up on sodium-heavy food (keep away from healthy foods), your body starts to sense that your salt and water levels are off kilter. To get things back to normal, you need to take in more water.
You might not think those salty chips you chowed down have anything to do with your throbbing headache. But research suggests otherwise: Adults who ate 3,500 mg of sodium per day had nearly a third more headaches compared to those who only took in 1,500 mg.
Going crazy on the salt shaker can leave you dehydrated. And when you are dehydrated, your ability to think clearly can start to plummet. When women were mildly dehydrated, they performed worse on cognitive tests measuring concentration, memory, reasoning, and reaction time compared to when they were adequately hydrated, found one Journal of Nutrition study.
