<p>I recommend that you don’t do this. I agree with Altsustar; sleep is important. Even if I have homework, I will skip it in favor of sleep. The possible upsides to sleeping less are, in my opinion, seriously undermined by problems brought on by a lack of sleep. It’s alot harder to take in information and learn new concepts when you’re tired, and one night of diminished sleep can wreck your rhythm for the whole week.</p>
<p>I try to get ~9 hours every night, including weekends. Even if I quit running, I would probably still try to get a solid 8 hours per night. I’ve met a few people who seem to be able to function well on less sleep, but they’re rare. If you want, try it for a few days, but be aware of how it affects your mood and learning capability.</p>
