Hot air dissolves and relaxes. If it is moderately hot, it makes the face red and attracts blood outward, and if its warmth is excessive, then the complexion becomes yellow, since the air dissolves the blood attracted outward. Hot air increases sweat and decreases urine output; it weakens digestion and causes thirst.
And cold air enhances and strengthens digestion and makes urine abundant due to the retention of moisture and their small release through sweat and the like. It reduces the amount of feces due to the compression of the muscles of the anus, which the rectum helps to maintain this position. The feces do not go down, since the passages do not contribute to this, and remain abundant, and the watery part of it is absorbed into urine.
Humid air softens the skin and moisturizes the body, dry air dehydrates the body and dries out the skin, and cloudy air makes the soul sad and raises the juices. Turbid air is not the same as dense air. Dense air is homogeneous in terms of the compactness of its substance, and turbid air is one to which dense bodies are mixed. Both of these air qualities are indicated by low visibility of small stars and faint,
like the flickering brilliance of shining luminaries at the moment. The reason for both is the abundance of vapors and smoke in the air and the lack of good winds. The discussion about this will be resumed and will be presented in full when we begin to present the changes in the air that go beyond the natural range.
Each season, proceeding as it should, has its own special laws. The end of each season and the beginning of the next have laws and diseases common to both of these seasons.
Spring, when it has its proper nature, is the best season of the year. It corresponds to the nature of pneuma and blood and, with its balance, which we mentioned, soon passes into a slight, “heavenly” heat and natural humidity. Spring flushes the face, as it moderately attracts blood to it, without going so far as to dissolve it, as it dissolves in the hot summer. In spring, chronic diseases arise, since spring | drives and makes stagnant juices flow; For this reason, melancholy in melancholic people worsens in the spring. Those people who have abundant juices in winter due to gluttony and little exercise are predisposed in the spring to diseases caused by these types of matter due to its spring dissolution. If spring lasts a long time, remaining balanced, then summer diseases decrease.
Spring diseases are bloody diarrhea, nosebleeds, exacerbation of melancholy, inherent in the nature of bile, tumors, ulcers, sore throats - they can be fatal - and other types of boils. In spring, vascular ruptures, hemoptysis, and cough often occur, especially during the winter period of spring, when it is similar to winter. The situation of people suffering from these diseases, especially consumption, worsens in the spring.
Since spring sets in motion the matter of mucus in people with excess mucus, then in spring there is sakta, paralysis, and pain in the joints. Among the reasons that plunge people into these diseases are excessive bodily and mental movements, as well as the use of intoxicating drinks: both of them help the nature of the air.
Nothing gets rid of spring illnesses better than bleeding, defecation, reducing food and increasing drinking, and also weakening the power of intoxicating drinks by diluting them with water. Spring is a time of year suitable for children and those close to children in age.
Winter is the best time for digestion, because cold compresses the substance of innate warmth, and the warmth intensifies and does not dissipate, and also due to the fact that in winter there are few fruits and people limit themselves to true food, move little in winter with a full stomach and take refuge in warm places.
Winter breaks down black bile better than any other season due to its coldness and shortness of the day with a long night. More than other seasons, it locks in bad juices and makes it necessary to take tearing and thinning medications.
Most winter diseases are mucous. In winter there is so much mucus that vomiting substances contain the most mucus. The color of tumors in winter is mostly whitish.
In winter they often suffer from runny noses. They begin with the change from autumn air to winter; A runny nose is followed by pleurisy, pneumonia, hoarseness, and sore throat. Then there are pains in the side itself, in the back, suffering of the nerves, chronic headaches and even sickness and epilepsy - all this is due to constipation of the mucous matter and its abundance. Old people suffer in winter, as do people who look like old people, and middle-aged people benefit from winter.
In winter, there is more sediment in the urine compared to summer, and there is also more quantity.
As for summer, it dissolves the juices and weakens the strength and natural functions due to excessive 6 dissolution of the juices. In summer, the amount of blood and mucus decreases and yellow bile becomes abundant, and then, at the end of summer, black bile due to the dissolution of the liquid part of the bile and the retention and constipation of thick bile. You will find old people and those similar to them strong in the summer.
And summer turns the complexion yellow, dissolving the blood it draws to the face. The duration of illnesses in the summer is reduced, because the patient’s strength, if they are great, finds an assistant in the air to dissolve the juices, brings the matter of the disease to maturity and expels it. If the forces are weak, then the heat of the air increases their weakness, making the body sluggish, the strength falls and the owner dies.
A hot and dry summer quickly resolves diseases, while a damp summer is persistent and the duration of illnesses is then long; therefore, most ulcers in such a summer end in necrosis. In damp summer, dropsy occurs, “slippery intestines”, “softening of nature”. This is all facilitated by the abundant flow of juices from top to bottom, especially from the head.
As for the diseases of the hot season, these are, for example, three-day fever, constant fever, burning fever, and weight loss. Pains during this period include ear pain and inflammation of the eyes. In summer, especially if there is no wind, there is often erysipelas and pimples that correspond to this season. When the summer is “spring”, the condition of fevers is good, they are not characterized by cruelty and dry severity. In damp summers there is profuse perspiration, usually it is expected only during crises, since a hot and humid summer contributes to this, because the hot dissolves, and the wet makes the skin soft and expands the pores. If the summer is similar to the “southern” one, then widespread illnesses and diseases of smallpox and measles are frequent; As for the “northern” summer, it promotes the ripening of juices, but in such a summer “compression diseases” become more frequent. “Compression diseases” are those diseases that occur when bad juice flows from internal or external heat and external cold strikes and compresses it. All these diseases are similar to catarrhs and similar diseases.
When the “northern” summer is dry, it is useful for people with a mucous nature and women. In such a summer, people with a bilious nature experience dry inflammation of the eyes, and chronic burning fever also occurs. Due to the combustion of yellow bile due to its constipation, sometimes a predominance of black bile occurs.
As for autumn, there are many diseases in autumn, because people often walk in the hot sun and then move to a cold place, and also because of the abundance of fruits that spoil the juices, and due to loss of strength in summer. Juices spoil in the fall due to bad foods, as well as due to the dissolution of light particles of juice and the preservation of dense particles that burn in the body. Whenever any juice rises in the fall, excited by nature to expel or dissolve, the cold locks it up again.
In autumn, blood greatly decreases in quantity, moreover: autumn is the opposite of blood by nature and does not contribute to its formation, and before summer already dissolved blood and this made it less. From the juices in the fall, yellow bile, remaining from the summer, and black bile multiply due to the fact that the juices are burned in the summer. Therefore, in the fall there is a lot of black bile, because summer burns juices, and autumn cools.
The beginning of autumn is to some extent suitable for the nature of old people, but the end of it is very harmful for them.
Autumn diseases are scaly scabies, scabs, cancerous tumors, joint pain, mixed fever, four-day fever - all this is due to the abundance of black bile for the reason that we have explained.
In autumn, the spleen also enlarges and urinary incontinence occurs, as the nature of the bladder changes from heat and cold. In the fall, urinary retention also occurs, which occurs more often than incontinence; There is also slipperiness of the intestines - and this is because the cold drives the liquid parts of the juices into the body - as well as inflammation of the sciatic nerve.
Zabh is in the fall, as it were, stinging, bilious, and in the spring - slimy, since both of them come from the juice that raises and drives the previous season.
In autumn there are frequent cases of dry ileus, there are also cases of sakta, lung disease and pain in the back and hips for the reason that the excess moves in the summer and is compressed in the fall.
In autumn there are often worms in the stomach, as the bodily strength is too weak to digest food and expel excess. Often, especially if the autumn is dry, smallpox occurs, especially if it was preceded by a hot summer. In the fall, cases of insanity also become more frequent - again due to the poor quality of bile juices, to which black bile is mixed.
Autumn is the most harmful time of the year for patients with tuberculosis of the lungs, that is, consumptives. At this time, what was unclear about the circumstances of the disease is clarified if it began before the fall and its manifestations were not obvious. This is one of the most harmful periods for those suffering from thinness - again due to the drying influence of summer. After all, autumn is like the confidant of summer in relation to the diseases left behind by it.
The best autumn is the wettest and rainiest, and the dry autumn is the worst.
