The brain and body are very much connected. Being bipolar, I am keenly aware of this.

Depression is a lot like being severely sick. Even if you manage to keep up exercise and diet, physical health takes a dive.

Mania… everything goes into overdrive. The necessary repair work isn’t being done, even if you get enough sleep.

Eating the wrong food or too much exertion can trigger episodes.

Mental health is very much tied to physical health. And vice-versa.
