Every hormone has a message, a destination and a job. Tap below to see where each notification comes from, which 'parts' get it and what it's asking for:
🙋♀️ Important: these are simplified examples. One hormone can act on several tissues, and only cells with the right receptor can respond to its signal.
🔍 Textbook Terminology: Cortisol helps the body respond to stress and helps make glucose and other fuel available.
👄 Girl Talk: “We’re awake / something needs attention. Make more energy available so we can deal with it.”
🔍 Textbook Terminology: Ghrelin is made mainly in the stomach and helps signal hunger to the brain.
👄 Girl Talk: “Brain? Stomach here. We could do with food soon — turn the hunger reminder up.”
🔍 Textbook Terminology: Insulin helps move glucose into muscle and fat cells and helps the liver store fuel.
👄 Girl Talk: “Fuel delivery! Muscle and fat cells, take glucose in. Liver, help store what we don’t need right now.”
🔍 Textbook Terminology: Oestrogen helps the uterine lining grow and also acts on the brain, bones and many other tissues.
👄 Girl Talk: “Uterus, rebuild the lining. Brain and other tissues, here’s the latest cycle update.”
🔍 Textbook Terminology: A sharp rise in LH helps trigger ovulation and the release of an egg from the ovary.
👄 Girl Talk: “Ovary, mature follicle: GO. It’s time to release the egg.”
🔍 Textbook Terminology: Progesterone rises after ovulation and helps prepare and maintain the uterine lining.
👄 Girl Talk: “Uterus, keep the lining ready. We’ve ovulated and we’re waiting to see what happens next.”
🔍 Textbook Terminology: Testosterone is also present in girls and women and acts on tissues including muscle and bone.
👄 Girl Talk: “Muscles and bones, keep supporting normal strength and maintenance. Also: yes, girls have testosterone.”
🔍 Textbook Terminology: Melatonin is released mainly at night and helps coordinate the body’s circadian, or 24-hour, timing.
👄 Girl Talk: “It’s dark. Brain and body clock, switch the schedule towards night mode.”
Hormones travel in the bloodstream. The notification only “opens” in cells that have the right receptor for that hormone.
