Signs caused by quality of sleep and wakefulness

If the patient sleeps during the day and not at night, this is not a good sign, and if he does not sleep either during the day or at night, this is even worse: then the cause is a disorder of the brain, whatever it may be. The safest daytime sleep is at the beginning of the day, and it is always worse at the end of attacks of fever, and at the beginning their sleep often comes and does no harm. Deep sleep with a weak pulse is a bad sign, since it occurs from weakness of strength, and not from moisture in the brain. This especially happens due to rotting of cold juice. Too much sleep during illness, leading to clouding of the mind and accompanied by coldness of the extremities, is not good, while sleep that brings relief is a good sign.
