The effects of sleep deprivation start slowly, then steadily build. While you work towards making up that sleep deficit, watch out for issues related to your insomnia sleep disorders.

Even one sleepless night can adversely affect your mental ability. You’ll have less energy to get through your day than you usually do and you can expect to experience effects of sleep deprivation. Your performance ability and level of alertness declines and some studies have shown that the impairment when driving is comparable to that of being under the influence of alcohol. So be careful when driving after a night or more of poor shuteye.

Feeling sleepy during the day and the actual lack of sleep also wreak havoc on your memory. You’ll need more time to complete simple tasks, as your brain has trouble making all the connections. Your ability to concentrate will diminish as sleepless nights continue.

When you’re feeling tired and having trouble completing tasks because of it, it’s only natural for irritability to follow. You’ll have less patience and get moody quickly if you’re not getting enough sleep. You might also feel stress more quickly and for less stressful events than if you were well rested.

If you go long enough without sleep, hallucinations may even happen. Your eyes will have trouble focusing and making connections with your brain, resulting in seeing things that simply aren’t there.

And finally, you can expect your brain to shut down throughout the day for micronaps. If you’re not getting enough sleep during the night, your body will try to compensate by falling asleep for a few seconds of time here and there. You may not actually notice this happening, but if you’re struggling with an insomnia sleep disorder, it surely is.
