At what point in studying should I give up for the night?

It is hard to retain information if you are tired. It is good to try to get at least 6 hours of sleep to help rest your mind and your body. By doing so, the next day you can feel refreshed and ready to continue studying.

When you become too tired to focus - e.g. struggling to read, starting to fall asleep or having trouble concentrating. It's important to study while your brain is properly active otherwise you will confuse the knowledge you learn. Sleep is necessary because this is the time where your mind processes information.

If you are at the point where you can barely keep your eyes open and are falling asleep. Go to bed and do your best the next day when you are refreshed.

This is an interesting question. Some people study for hours, while others can only study in short periods of time with breaks. One important consideration in when to give up studying for the night, is good self-care. Are you getting enough sleep, eating regularly and getting some exercise? Are you doing well on your school work or do you feel like it's not retaining? Maybe consider changing some things up to figure out the best time of night for you to stop studying. Experiment with it and the way you study to find the right answer for you.

Set a goal on how much you should study, once you have hit that goal retire for the night. Split the amount to study equally for all the days you have so that you don't over do in a day.

I think when you cant concentrate anymore or you notice that you will not get enough sleep. I think at least 4 hours, because after that the first shedule of sleeping is over. The most healthiest is 7 to 8 hours.

When you feel like you cant absord anything more, and are dosing off while studying. It's better to sleep for some time and then wake up re energized.

Good question! It depends if you're on a short term or a long term studying. You should consider criteria like your studying efficacy, your mental arousal that may result in difficulties to fall or to stay asleep, the consequences on your functioning the next day etc. We might try to reformulate your question as how to best organize my life in order to be able to keep on studying for long periods of time (usually years), and achieve the academic results you may hope for. I would suggest words like : regularity in life and studying, good task and time management, self regulation skills to take good care of your emotions and biological needs in general, regular physical exercise, good night sleep, regular meditation or mindfulness practice, strong social support, and regular active involvement in leisure activities. Once all this is checked, you might already have the answer to your initial question "at what point in studying I should give up for the night".

Don't see it as giving up, you just have to find the right ratio of study-sleep. As sleep is a very important and underrated part of studying. Make sure you've at least read everything once so you feel like you've covered everything. The ratio can differ from person to person and subject to subject, as for some pulling an all-nighter and getting some strong coffee works, for others maybe going to bed early when they have read every once helps so that they have a clear mind to think in the morning. Remember, it doesn't matter what you do, there are no rules. Do what you think is best. You're only going to have this kind of stress for a little period in your life, as weird as it sounds, try to enjoy it, or at least LIVE it. It's a part of your life and you get to decide how to handle it!

I would recommend that you stop studying when you feel tired, or like you can no longer focus. Studying is only effective if your mind is fully present; otherwise, it is not going to do much to help you. Besides, sleeping is definitely a key factor to doing your best in school; if your studying cuts into sleep time, it may be doing more harm than good! I don't think that there is a specific time that you need to stop studying at, or a certain amount of content that you must get through. Whenever you feel your focus starting to slip, it's probably best to call it a night.
