What happens if you don't sleep for 7 days?

I heard someone say they went without sleep for three days and it was awful. It got me thinking, what would actually happen to a person if they didn't sleep for a whole week? Like, is it even possible to survive that long?

Severe insomnia like this can be linked to extreme thyroid fluctuations or other hormonal issues. Please get your thyroid profile and blood tests done immediately. You need to consult a physician as soon as possible to find the root cause of this lack of sleep.

Boss, not sleeping for 7 days is practically impossible and extremely dangerous. Your brain will start shutting down and you will start hallucinating by day 3 or 4 itself. If this is a real issue you are facing, stop reading online and go straight to a hospital doctor right now.

I can't even stay awake for 24 hours without craving three rounds of mid-night snacks and tea! 7 days of no sleep is wild and would completely crash your digestive system and appetite. Please take care and get some proper rest.

Don't believe any internet articles claiming you can cure severe sleep deprivation with breathing hacks or music. Staying awake for a week can cause serious cardiovascular and psychological risks. You need immediate medical attention from a proper sleep specialist or general physician.
