What are free radicals?

Free radicals are atoms that contain unpaired electrons, due to this, there is a lack of stable number of electrons. They are in constant search to bind with an electron because they are unpaired, and to stabilise themselves. This causes damage to the DNA and other parts of the human cell. This damage plays a role in accelerating the ageing process. Free radicals are highly reactive, unstable molecules. They are produced by the body naturally as a byproduct of oxidation or metabolism when exposed to toxins in the environment, UV rays or tobacco smoking. Free radicals only have a lifetime of a fraction of a second but during this time they can cause damage to the DNA which sometimes results in mutations and because of this mutation people sometimes even get cancer.
