CrowdScience listener Leo gets stressed when his young children start screaming at the same time in the middle of the night. He wants to know why we haven鈥檛 evolved to deal with the stress more effectively. The challenges of bringing up a family are nothing new and we don鈥檛 face the same dangers as our ancestors, so why do we still react as if it鈥檚 a life-threatening emergency? Caroline Steel finds out what stress is for, what it does to us and whether we have in fact evolved to manage it.
