We'd DIE without our Hormones.
All of our Hormones are constantly communicating with each other and telling the DNA in our CELLS what to do... PLUS they are telling each OTHER what to do too.
Got High Cortisol? That leads to Low Thyroid.
Got Low Cortisol? Well that leads to Low Thyroid too!
Low Estrogen? Get ready for some sadness and irritability... because that causes Low Serotonin.
Low Progesterone? Bummer... You're facing Insomnia since now your GABA brain hormone (Gamma-aminobutyric acid) will be Low.
