Zoella.co.uk: Happy Hormones and How To Hack Them

“Hormones are essentially chemical messengers in the body,” says Dr Margarita. 

They travel around and affect different organs and tissues, working slowly and over time affecting various physiological processes including:

• Mood

• Growth and development

• Metabolist: how the body gets nutrients and oxygen

• Sexual function and reproduction.

“Hormones are produced by endocrine organs, which are groups of specialised cells, situated in different locations across the body. The endocrine glands include the pituitary, pineal, thymus, thyroid, adrenal, pancreas and sexual organs such as testes in men and ovaries in women. 

“Hormones are powerful substances! Even a small quantity of hormones can trigger a big reaction in cells across the body. For example, Insulin, produced by the pancreas is a response to food ingestion. It facilitates the digestive processes and controls the transfer of glucose from the bloodstream, into each human cell that needs it to function.”
