I became fascinated with the subject of sleep and sleepiness during my Psychology undergraduate degree at Loughborough, and that fascination has just continued to grow! Sleep is something that everyone experiences but it is also such an individual experience. We all feel sleepy at various times, however, increased sleepiness at the wrong time can be potentially dangerous, for example when doing something safety critical such as driving. Researching how people choose to counteract sleepiness during safety critical tasks and why they choose to use what they use has the potential for real-world impact and practical application, which is something I think is very important.
