leptin is an interesting one, it is a hormone that regulates how much you eat. The more fat you have in your body, the more leptin you produce, which suppresses the feeling of hunger.

You could also do prolactin, which is a hormone that stimulates the production of milk in the breasts, but also reduces sexual behaviour.

Another good one is cortisol, which is a hormone that essentially gives you energy, it is the hormone that gets you out of bed in the morning and is released in response to stressful situations such as infection.

There are bound to be many others, but I feel like these are the most relevant to the question. If you have any questions about the endocrine system then ask me, I'm about to start a 3 week endocrinology placement so I'm a bit of an endocrinology nerd atm!

You could use the diurnal release of melatonin (a hormone which regulates the sleep-wake cycle and is released by the pineal gland) which is mediated by external environmental light levels detected by special retinal cells. AortaStudyMore has given you some good ideas here.

That's a good one too, there are specialised retinal ganglion cells which synapse with the suprachiasmatic nucleus in the hypothalamus, which stimulates melatonin release from the pineal gland, which in turn stimulates the ventrolateral preoptic nucleus. This suppresses the reticular activating system, therefore making you sleepy.

The possibilities are almost endless with endocrinology
