Mods like first aid divide the health bar into different segments, with the head and chest being critical: lose all hearts there and you'll die. Effects such as hypo/hypothermia which are intended to reduce the player health to I believe 25% in vanilla do not take these changes into account, meaning the head gets targeted first and you'll die within the first 40 seconds of the effect. Not to be confused with standing next to lava or being in an ice storm which should kill you, the long lasting effect takes 5 minutes.
I would recommend compatibility: changing it the way first aid does with poison to target all other limbs before targeting the head and chest. That, or the easier option of keeping the temperature system, but allowing the player to remove the long term 5 minute effect as it currently kills when it shouldn't.
