Sodium: The key to life

Series 3

BBC Radio 4 - In Their Element, Series 3, Sodium: The key to life

Sodium, the explosive alkali metal that is crucial for all life on Earth.

Scientists tell stories of the elements. Sophie Scott on why sodium powers everything we do and why it might be the key to a new generation of pain killers.

Putting sodium into water is one of the most memorable experiments from school chemistry lessons. It's this ability to react ferociously with water which is the starting point for sodium's key role in powering all of biology. Simply, without sodium we wouldn't exist. It helps provide the electricity that allows us to move, breathe, think. Our understanding of sodium could help in the search for analgesics with few side effects for severe pain. Recent discoveries of families who feel searing pain with mild warmth, or those who feel no pain at all even in childbirth, have opened up new avenues in pain research. Their rare genetic mutations change the way sodium works in their bodies: from this new knowledge neuroscientists are developing drugs that could give rise to a much needed new generation of pain killers.
