Why can’t I sleep after being awake for two days?

The internet states the following about your condition:

Being awake for two days triggers a paradoxical biological response where extreme exhaustion actually makes your brain and body more awake and alert.

The main reasons this happens include:
Flight-or-Flight Response and Cortisol: When you go without sleep for a long time, your body perceives the prolonged stress as a crisis. It pumps out stress hormones like cortisol and adrenaline, elevating your heart rate and tensing your muscles. This keeps you wired even when you are exhausted.

Racing Thoughts and Hyper-Arousal: Severe fatigue can lead to mental over-activation, racing thoughts, anxiety, or a feeling of being "too tired to sleep" (often tied to acute stress or Paradoxical Insomnia).

Disrupted Circadian Rhythm: Staying awake past your normal sleep cycles confuses your internal biological clock, making it hard for your brain to recognize when it is finally time to power down.

Microsleeps and Depersonalization: At the 48-hour mark, your brain begins to experience extreme deprivation effects like cognitive fog, temporal disorientation, and anxiety, which can make settling down nearly impossible without a calm environment or intervention.
