Why evolution doesn't want you to sleep when you're stressed

The article explores how stress impacts sleep patterns from an evolutionary perspective. It highlights that our ancestors faced threats that required constant vigilance, leading to a biological design where stress hormones like cortisol can override the need for sleep. This modern-day struggle with insomnia may stem from these ancient mechanisms, which are still hardwired in our brains. Understanding this evolutionary context can help explain why stress often leads to sleepless nights and underscores the importance of addressing stress for better health outcomes.
