It becomes a problem at square 1 because it can affect your health and be very bad for the physical and mental health. It can cause lasting damage.

Sleep deprivation becomes a problem when it's affecting you negatively in different parts of your life

When you have hallucinations. Sleep deprivation can cause drops in work/school progress, mood changes, and hallucinations.

Sleep deprivation can cause a lot of negative symptoms. Our bodies need rest to allow us to have energy and motivation to conquer the daily tasks we have. I understand we live in a fast-paced world and sometimes getting a full night of sleep every night can be hard. I try to remember that sleep is important and valuable. Sleep allows me to be a better, more energetic person the next day. I now count sleep as self-love and self-care. Staying up and not sleeping enough led me to being constantly tired, not feeling well, and not enjoying my days as much. If the lack of sleep is negatively effecting your life then it should be considered a problem. You deserve to feel well and rest well. You deserve to have the rest and energy you need each day.

sleep deprivation becomes a problem once it affects your mood. not sleeping can actually make you more depressed and it's not good for you, nice the average human being needs 7-8 hours of sleep

As with many issues, sleep deprivation can quickly become a problem when it interferes with your ability to function as you normally would with your family, friends, your community, and at work. It is a serious health concern and should not be taken lightly as it negatively impacts your ability to think clearly, and is detrimental to your physical and mental health.

Loss of sleep at any time is generally a problem! Multiple studies and our bodies alone show us that sleep is imperative for our mood, bodily functions, job performance, etc.! Normally our bodies can jump back from a long, late night but if it's a string of long, late nights your body can't keep up, internally repair itself, "reboot" for the next day, or retain information as well.

As with most things, sleep deprivation becomes a problem when it starts affecting your everyday life and/or your health. Getting about 8 hours of sleep each night is extremely important to your overall health.

Sleep deprivation starts to become a problem if and when it interfers with your everyday life. If your sleep deprivation causes you to have problem focusing on everyday tasks, making your more irritable or having problem performing normal every day tasks then you should probably start looking into treating whatever is causing your sleep deprevation. Another way to see if sleep deprivation starts becoming a problem is if you start pulling towards more coffee, energydrinks and sugary snacks than usual during your day as they're a way to trick your brain to feel more alert despite not adressing the actual problem at hand.

I personally believe sleep deprivation becomes a problem when it begins prohibiting you from functioning normally on a daily basis. If you are unable to perform basic tasks or find yourself slow on the uptake of performing basic tasks, your lack of sleep is becoming a big problem. There have definitely been times in my life when I haven't allowed myself enough time to rest at it affected me greatly the next day to the point that it terrified me. It is absolutely possible to function on lack of sleep but it's not something that I would recommend to anybody.
