    90 F to Kelvin, halved and converted back, is approximately -190.

    It’s difficult to find data on what exposure to that temperature would do, the threshold for an extreme cold warning (meaning absolutely do not go outside without heavy protection unless you want necrotic frostbite) is about 150 F warmer than that.
