Lemnius, _l. 3. c. 3_, discommends the south and eastern winds, commends
the north. Montanus, _consil. 31._ [1533]"Will not any windows to be opened
in the night." _Consil. 229. et consil. 230_, he discommends especially the
south wind, and nocturnal air: So doth [1534]Plutarch. The night and
darkness makes men sad, the like do all subterranean vaults, dark houses in
caves and rocks, desert places cause melancholy in an instant, especially
such as have not been used to it, or otherwise accustomed. Read more of air

SUBSECT. VI.--_Immoderate Exercise a cause, and how. Solitariness,
Idleness_.

Nothing so good but it may be abused: nothing better than exercise (if
opportunely used) for the preservation of the body: nothing so bad if it be
unseasonable. violent, or overmuch. Fernelius out of Galen, _Path. lib. 1.
c. 16_, saith, [1535]"That much exercise and weariness consumes the spirits
and substance, refrigerates the body; and such humours which Nature would
have otherwise concocted and expelled, it stirs up and makes them rage:
which being so enraged, diversely affect and trouble the body and mind." So
doth it, if it be unseasonably used, upon a full stomach, or when the body
is full of crudities, which Fuchsius so much inveighs against, _lib. 2.
instit. sec. 2. c. 4_, giving that for a cause, why schoolboys in Germany
are so often scabbed, because they use exercise presently after meats.
[1536]Bayerus puts in a caveat against such exercise, because "it
[1537]corrupts the meat in the stomach, and carries the same juice raw, and
as yet undigested, into the veins" (saith Lemnius), "which there putrefies
and confounds the animal spirits." Crato, _consil. 21. l. 2_,
[1538]protests against all such exercise after meat, as being the greatest
