Humans need approx 1tsp (or less) of sodium daily as an essential nutrient. I was low on sodium this morning* then spent the day at the beach in the salty ocean air, then within about 30 minutes I wasn't dizzy and nauseous anymore. Did the ocean air provide me sodium somehow?
*(dizzy & nauseous, I know the symptoms well since I often have no sodium in my diet and I've learned this through experience the last 5 years and I have to consciously remember to add sodium to my diet, and if I forget then I have dizziness and nausea)
Reddit wouldn't let me post this for some reason, Maybe because that subreddit r/askadoctor is dead, there have been no posts there for 3 years, so instead of abandoning my attempt at a post, I screenshat it and posting it here on Lemmy.
I too have to consciously give myself a little extra sodium due to diet issues. I buy a single bottle of Gatorade every week and take a swallow before bed every night. That seems so do the trick for me and I don't have to change what I eat.
