What happens if you don't sleep for 2 days?

Could you elaborate on the potential consequences of not sleeping for two consecutive days? I'm particularly interested in the effects it might have on cognitive functions, physical well-being, and emotional stability. How does it impact decision-making abilities, especially in high-stakes scenarios like those in the cryptocurrency and finance industry? Are there any specific symptoms or warning signs that one should be aware of? Also, is there a way to mitigate the negative effects of sleep deprivation, or is it simply a case of needing to catch up on rest as soon as possible?
