insalubrity

noun

1. (uncountable, usually)The condition of being insalubrious; unhealthiness, unwholesomeness

   “[S]uch an one […] recalls as a vision of Paradise the land he has learnt to love; he exaggerates the insalubrity of a northern climate; he bewails the wretched formality of our civilised life, and so, back to the distant solitudes flies his recollection like a dove to the wilderness.”
