Akshat Rathi recounts his experiment with trying to sleep less and find more hours to fit in work and study, according to Quartz.

After three weeks and a few more obstacles, I finally settled into the new schedule. I was getting 4.5 hours of sleep in total, which was just a little more than half the hours I used to sleep.

The extra time was proving to be a wonderful benefit: I finished my first-year thesis; successfully defended it; decided that after finishing my doctorate I didn’t want to be in academia for the rest of my life; got a chance to explore Oxford University’s wonderful offerings without sacrificing on lab time; started exploring other career options, including writing, which eventually led me to become a journalist.
