After 20+ hours without food, you lose electrolytes through saliva and urine.
A pinch of Himalayan salt in water restores sodium, kills headaches, and keeps energy stable.
During fasting your insulin drops. Low insulin tells your kidneys to dump sodium.
That’s why people get headaches, fatigue, and brain fog — it’s not lack of food or coffeine, it’s lack of sodium!
Also, wearing clear aligners 23 hours a day means more saliva production (your mouth thinks there’s something to chew).
More saliva = more sodium loss through swallowing and rinsing.
