Salt and coldness

Does anyone experienced coldness after eating a lot of salt? Everytime I eat a lot of salt like a tsp added to meal I experience cold feet, thighs and arms but not hands.

It's said that salt can reduce stress hormones. Those hormones may have been keeping you warm, and reducing them will then reveal a cold, hypothyroid state. I can't really explain why specific parts get colder than others - circulation issue, Reynaud's phenomenon perhaps.

No, it usually raises body temperature even if it decreases adrenaline.

It could be the meals making you cold, but you have to be careful not to overdo it on salt. Overall, sodium should be consumed preferentially over potassium, but you should never eat more salt at a time than what tastes good to you.

Also, sodium in itself doesn't seem to shut down the stress response, but when it is coupled with starch, sugar, protein, and some fat, it does its job. Try not to view salt as an isolated variable, but rather one factor among many that you should be focusing on simultaneously. When all the variables are dialed in just right, including the salt, then things start to work. If you just focus on the salt and try to consciously eat more of it all the time, you can actually create a stress response rather than shutting one off.

Should I comment on the blog? or here? It think it's an interesting point you've raised there, as usual.

As you like, maybe here, because the discussion was started here.

I think Peat's answer to this might be something like: as edema or extracellular water increases, so does the need for salt, in order to maintain osmotic tension.

People with the highest salt intakes may also have the highest edema, and therefore need high salt intake. But because they are probably being advised to reduce salt, rather than eat salt to taste (i.e., even more salt than they are eating), their salt levels while high, are not high enough, leading to cardiovascular disease.

It's a thought experiment, of course (and I haven't asked him this question).

This is really interesting vision and i agree that it should be like that. Its just once i start to increase salt i get edema. And the more i increase the salt the more thirsty i get and the more retention i get. Maybe i just need to smack down more and more salt to finally it just WOOOSH i get the right osmotic tension.

Whats your thought on that? I dont get water retention from sodium bicarbonate tho
