Need help with a thesis and hook

Question

Effects of caffeine consumption on sleep

Answer 1

For your hook you want to motivate your research/thesis topic while snagging the audience's attention. It should speak to the problem your hypothesis seeks to solve.

Example 1: "Caffeine consumption disrupts sleep in [X]% of people, leading to higher overall motility and morbidity compared to those who have [Y] hours of undisrupted sleep." speaks to a problem with caffeine, which could be the main theme of your thesis.

Example 2: "To this day, there are no effective over-the-counter remedies for AHDH." speaks to a knowledge gap in the field. This would be used in a thesis where the main point is 'today we found a way to medicate ADHD with common caffeine!'***

I recommend you look for a communications lab or communications hub at your school, and see if they have any resources as to the school's preferred thesis structure. Here is an example of a great resource for EECS paper writing [specifically looking at the introduction]: https://mitcommlab.mit.edu/eecs/commkit/journal-article-introduction/

***disclaimer: there is no known evidence that caffeine is effective for medicating ADHD.

Answer 2

I would start with a brief expository lead in, transition to a quote or statistic, and then tie that into what your argument will eventually be.

Something like:

"From our morning coffee, to supplements, energy drinks, and even cosmetic products, caffeine has become a ubiquitous presence in the modern-day experience. Not surprisingly, studies (you can name the studies here) have shown that as caffeine consumption has increased over the years, so too have reports of sleep disruptions and disorders. (you can put a citation here) Clearly, given the relationship between quality sleep and overall health, it has become more important than ever to take a closer look at our modern day caffeine addiction, and the myriad of health problems it contributes to."

This is very general, but it is one way you can approach the first paragraph. Just make sure to properly use and cite your sources!

Best,
