Can lack of sleep kill you?

Please don't take extreme sleep loss lightly. I used to pull continuous all-nighters until I passed out one day and had to be rushed to the hospital with severe exhaustion. If you are experiencing severe sleep issues, please see a doctor immediately.

Don't worry, staying up late occasionally won't kill you, so please don't panic. But yes, severe long-term sleep deprivation is very harmful to your heart and brain. Take a deep breath, put your phone away, and let's try to sleep on time tonight.

My health tracker shows a terrible HRV and spiked resting heart rate when I sleep poorly, which is bad for longevity. While it won't kill you instantly, long-term sleep debt increases your risk of chronic diseases. Track your sleep and prioritize it.

This question is so scary to think about, but I actually worry about this when I can't sleep for days. My chest feels so tight and my heart races. Has anyone else felt this extreme panic from no sleep, or is it just my anxiety?

While missing a night's sleep won't be fatal, chronic sleep deprivation can lead to severe health complications like stroke or heart failure. I had a relative who suffered greatly due to untreated sleep apnea. Please consult a doctor if you can't sleep.
