Could "rock solid" cardboard beds at Olympics impact performance? A sleep expert weighs in.

To complete at the Olympic level in Paris this year, athletes surely need a good night's rest — but that doesn't seem to be the case for some athletes sleeping on the viral cardboard beds in the Olympic village. 

The beds, which many have joked are "anti-sex" beds due to the materials used, have actually proven to be quite sturdy — almost too sturdy, it appears, as athletes have taken to social media to show how uncomfortable they apparently are.  

Australian water poloist Tilly Kearns posted a video to TikTok earlier this week that showed how rough her first night was in the bed.
