I know it's advised to get 8-9 hours of sleep but as a college student, I find myself getting about 6 hours of sleep on average and some nights it's as little as 4. Over the weekend, I can get about 8-9 and though I'd like to get 10-11, nowadays, I find it hard to sleep in (even after a night out).
Is eating right and doing exercise pointless if you don't get enough sleep? Should you eat more/exercise less on days where you don't sleep enough?

Life is about managing stress. I don't know how much you work out but for me I don't bother lifting heavy in weeks where I sleep badly, it just doesn't seem to help. Same goes for hardcore sprints. If it were me and I was going to change my habits for sleep deprivation I'd -
I'd keep carbs on the low-side to avoid gaining.
I'd do maybe 1-2 days at the gym with very low volume. I'd maybe do one lifting day and 1 sprint day
I'd just go hiking a couple of times a week to get some sun and some air and blow off some stress.
There is a threshold where exercise makes you sleep better Vs. keeping you up at night. Maybe drop down to 0 workouts and then add them back slowly and see where the balance point is.

First, I can't really say what you should do for exercise or eating when you are sleep deprived, but I like LikesLardinMayo's answer. Some thoughts, with studies for your perusal:
(Sleep may beat the extra studying...)
Neurocognitive Consequences of Sleep Deprivation
Deficits in daytime performance due to sleep loss are experienced universally and associated with a significant social, financial, and human cost. Microsleeps, sleep attacks, and lapses in cognition increase with sleep loss as a function of state instability. Sleep deprivation studies repeatedly show a variable (negative) impact on mood, cognitive performance, and motor function due to an increasing sleep propensity and destabilization of the wake state. Specific neurocognitive domains including executive attention, working memory, and divergent higher cognitive functions are particularly vulnerable to sleep loss. In humans, functional metabolic and neurophysiological studies demonstrate that neural systems involved in executive function (i.e., prefrontal cortex) are more susceptible to sleep deprivation in some individuals than others. Recent chronic partial sleep deprivation experiments, which more closely replicate sleep loss in society, demonstrate that profound neurocognitive deficits accumulate over time in the face of subjective adaptation to the sensation of sleepiness. Sleep deprivation associated with disease-related sleep fragmentation (i.e., sleep apnea and restless legs syndrome) also results in neurocognitive performance decrements similar to those seen in sleep restriction studies. Performance deficits associated with sleep disorders are often viewed as a simple function of disease severity; however, recent experiments suggest that individual vulnerability to sleep loss may play a more critical role than previously thought.

The metabolic consequences of sleep deprivation
"The prevalence of diabetes and obesity is increasing at an alarming rate worldwide, and the causes of this pandemic are not fully understood. Chronic sleep curtailment is a behavior that has developed over the past 2???3 decades. Laboratory and epidemiological studies suggest that sleep loss may play a role in the increased prevalence of diabetes and/or obesity. Current data suggest the relationship between sleep restriction, weight gain and diabetes risk may involve at least three pathways: (1) alterations in glucose metabolism; (2) upregulation of appetite; and (3) decreased energy expenditure. The present article reviews the current evidence in support of these three mechanisms that might link short sleep and increased obesity and diabetes risk."

Okay, maybe you are sleep deprived at 4-6 hours per night, maybe not. What do I know? But if you don't feel fully rested, you could try my strategy for when I'm tired. I take a nap. Usually lasts 20-30 minutes. My cats are really good at this. It's quite refreshing.

sleep is 1/3 of the equation (along with diet and exercise) so rather than trying to figure out a way of side-stepping the issue of sleep, you need to find ways to get the sleep you need. Have you darkened your room properly? Do you do things in your bed besides sleep and be romantic (like study or watch tv)? If so, stop. Are you budgeting enough time for sleep? You need to schedule it, just like you set aside time for your workouts. Alcohol actually lowers the quality of our sleep, btw, so using a night out as a way to sleep in is not a good plan.

Like the above comments say, you need to prioritize sleep. It is so important for physical and cognitive functioning and I wrote a post about it actually;
However, for those times when you really can't get enough sleep, meditation has been shown to reduce daily sleep requirements. This actually spurred me to write about meditation and start trying it out myself. It has many benefits other than just reducing sleep requirements.
I hope the above is helpful for you, but in the end, prioritizing sleep will help with your overall performance, physically, emotionally, socially, and academically.

Well, I'll answer the question because no body else actually did. I'm not sure how old this is though but an answer couldn't hurt.
Eat, you should eat allot more. People burn about 400 calories just by sleeping so really you need to double that number to maintain your energy level without sleeping so you don't have awful fatiguebut you also need tto double that to increase your energy levels to proper functionally. So really if you eat 200 calories a day and burn off 300 calories in an 8 hour sleeptime yyou should eat an extra 500-600 calories daily. So that would be 2600 ish MINUS exercis . You would need to eat even more with exercise but at the levels of your sleep I wouldn'tssuggest even exercising because of how hard it will be to keep up your energy already. I've got a masters degree in Medical Science and I'm also a physical trainer. Good luck, but if it's possible I really would suggest trying to get more sleep. If it's a matter of falling asleep then I 100% recommend Melatonin . It's in a small chewable capsule. I took it all through childhood and it would give me a solid 8-10 hours sleep in a 5 MG tablet. If it's just a busy life style then I can see how it might be tricky. But take care of yourself. It's hard to function this way. I do suggest really timing out your studies nd getting proper minimum of 7 hours of sleep. I don't admire your determination in your school work. Good luck! -Mark
YOU can look up a calculator of how many calories you burn during sleep. As can you with your daily calorie recommendation.

A few things. Firstly, the eight hours is a recommended length but it's more of a guideline. Some studies have shown that having that much sleep can, in fact, be detrimental and there is a lot of evidence to suggest that you need more or less sleep at different times of your life depending how your body changes. What is more important is the quality of the sleep that you do have. This can be difficult, particularly if you have a lot of things on your mind. Good regular exercise and a healthy diet can contribute to how well you sleep during those hours of sleep that you do get. Try to relax before you go to bed and find a natural way to unwind. Be as comfortable as you can be and don't fight against the sleep. Getting all of the thoughts of the day out of your head is not easy, but the better you prepare yourself for the night the better sleep you will get.

Exercise is important so go ahead and exercise. However keep your intense sessions below 45 mins. So you could go for a walk 5 times a week for 30 min (low intensity and would not count against the 45 min limit) and then lift weights. Or you could do a body weight exercise routine in place of lifting.
