Electrolytes: Why Your Body Needs Them?
Electrolytes, as their name implies, are required for processes in the body that rely on a small electrical current to function.
I had a discussion with a friend the other day who stated quite simply: “We are really just complex puddles of water that need an electrical charge to work.”
Though it’s a funny explanation, electrolytes are necessary for most bodily processes of everyday life.
The Main Electrolytes in the Human Body Include:
Automatic processes like nerve and muscle function, hydration, blood pressure and tissue repair all rely on optimal electrolyte status.
Magnesium is one of my favourite minerals. Our bones readily take up magnesium at a high rate, so it’s no surprise that 60% of the magnesium in your body is found in your bones. Energy production, lactic acid removal, and immune function all rely on optimal magnesium intake. Athletes deficient in dietary magnesium intake may have a significant reduction in exercise performance when compared to their peers. Excessive alcohol intake, gastrointestinal problems, anorexia, and certain medications may predispose an individual to insufficient magnesium status.
Magnesium is also a helpful nutrient for headaches; whether they are tension, cluster, menstrual-related, or migraines. Numerous studies investigating the effects of magnesium supplementation have reported beneficial results on number of days with a headache, frequency of attacks and total pain scores.
If you suffer from chronic headaches, it is important to be assessed by a healthcare practitioner. Ask your healthcare provider whether magnesium supplementation is safe for you. The most commonly reported side effect with magnesium supplements is diarrhea; especially with forms of magnesium that are poorly absorbed.
Other diet and lifestyle factors can result in loss of important electrolytes.
One study looking at caffeine consumption in healthy young females found that higher amounts of caffeine intake can cause loss of sodium, calcium, and magnesium. Higher intake of caffeine per body weight caused increased urinary output of sodium, calcium, and magnesium. If you’re a regular coffee or tea drinker, you might want to consider upping your vegetable, nut, and seed intake to help with potential electrolyte loss.
If you’re someone who is exercising regularly, you might also want to assess your electrolyte intake. Exercise is one of the most beneficial things you can do for your health, but if you are lacking hydration your body will not perform to the best of its abilities. Sweat contains not only electrolytes but also B vitamins (required for energy production) and vitamin C.
If you’re consuming a low fat or low calorie diet, and your consumption of fruits and vegetables is low, you are more likely to develop an exercise-induced nutritional deficiency.
Here’s a tasty recipe for an electrolyte drink that you can use to recuperate from strenuous exercise. I like this version because it does not contain refined sugars, vegetable oils, or artificial colours.
Easy Electrolyte Drink
- 2 cups coconut water
- ½ tsp table/sea/pink salt
- 2-4 tsp maple syrup or honey
- ½ lemon juiced
Mix together and keep chilled for a hot day/post workout!
