Recent studies have shown that the human circadian clock depends on the concentration of sodium and potassium in the brain.

The researchers found that when the concentration of sodium and potassium rises on one side, the other goes down.

It explains that in order to maintain normal body functions, it is balanced by self-regulation.

At night, the potassium control pathway was activated, and during the day, the sodium control pathway was activated.

The researchers also experimented with altering the animal's genes to eliminate the neural pathways that regulate sodium and potassium.

As a result, animals with no sodium control pathways fell asleep during the day.

Conversely, animals that had eliminated the potassium control pathway could not sleep at night.
