They are idealistic, and most come to medicine because they are inspired to contribute Emotional and physical fatigue lead to behavioural changes. Decreased interest in activities that were once enjoyed during free time leads to social withdrawal and personal isolation. However, the profession of medicine is demanding, and it is Relationships with family and friends are compromised, and diffcult to put limits around its practice. Poor constant exposure to suffering, heavy workloads, long hours, coping strategies that are adopted might include the increased time pressures, physical and mental demands, and a lack of intake of caffeine and alcohol, or the use of illicit drugs. Physicians are acutely Faced with some or all of these effects, one might experience aware of the distress of others but are often less attentive to at the same time a reduced sense of accomplishment and the stress and fatigue that they experience themselves. It is easy to lose sight of one’s accomplishments caring for others often leads to neglect of oneself. This is the sign of We know that physicians, as a group, are well informed with signifcant stress. We also know that when physicians are overwhelmed by the demands Given that the demands of the profession are ever present, of their profession, they are vulnerable to neglecting those what is the solution? It requires, frst and foremost, awareness of the risks mises not only the physician’s health, but his or her ability to that will be present and deliberate attention to measures of continue to provide care for others. Physicians’ self-care presents a perfect opportunity to practise preventative care. When self-care is neglected When a physician becomes immersed in his or her work to the Solutions: Think “self-care” exclusion of self-care, a cascade of stress-induced symptoms In The 7 Habits of Highly Effective People, Steven R. A feeling of being chronically overwhelmed a compelling case for what he describes as the “Principles of leads to frustration and irritability. The physician may become Balanced Self-Renewal,” which he describes as “preserving and prone to emotional outbursts, or may be tearful at work in enhancing the greatest asset you have–you. He or she may take domains that require attention in self-care: physical, emotional, less pleasure in activities that were once much enjoyed. Effective self-care requires consideration meantime, a denial of the signifcance of these symptoms and of these four domains, and taking control of the things that the vulnerability they reveal can lead the physician to take on can be controlled.

However, although they apply this knowledge on a daily in the activity and make a commitment to participate regularly.

Ter- On Treatments for Women tion falls this way and that, as if it were wandering. Therefore, take the tops of elder and grind them and, having extracted the juice, mix with barley ﬂour and with the white of an egg, and then make little wafers with suet for eating. On the Preservation of Celibate Women and Widows  There are some women to whom carnal intercourse is not permitted, sometimes because they are bound by a vow, sometimes because they are bound by religion, sometimes because they are widows, because to some women it is not permitted to take fruitful vows. Take some cotton and musk or penny- royal oil and anoint it and put it in the vagina. And if you do not have such an oil, take trifera magna6 and dissolve it in a little warm wine, and with cotton or damp wool place it in the vagina. Note that a pessary ought not be made lest the womb be damaged, for the mouth of the womb is joined to the vagina, like the lips to the mouth, unless, of course, conception occurs, for then the womb withdraws. But because some women are fat, as though they had dropsy, and some women thin, both the former and the latter are incapable of conceiving. If she is phlegmatic and fat,7 we should make her a bath of seawater, moderately salty, with rainwater. In this bath she should stay until she sweats suﬃciently; afterward let her be received in bed carefully and let her be well covered. Thus let there be made for her a bath three or four times that day, and likewise the following day. On the third day, let there be a very good, strong-smelling fumigation, as we described above. Queh postquam satis sudauerit, abluat se cum aqua pri[ra]oris balnei, et sic cautei intret lectum, et hocj ﬁat bis uel ter uel quater in ebdomada, et satis gracilis inuenitur. Facimus eis sepulcruma iuxta litusb maris in harena, et modo dicto illiniesc eos, et cum calor est fortissimus, quasid in sepulcro ponimus, quasi infundendo harenam calidam, et ibi facimus eos multum sudare, et post cum aqua priorise balnei optimef lauamus.

Extrahimus succum porri et dis- temperamus cum oleo pulegino uel musceleoc uel succo borraginis, et de- ¶a. Then let her enter a steambath up to the neck, which steambath should be very hot from a ﬁre made of elder [wood], and in it, while she is covered, let her emit a lot of sweat, and as though in a sweat bath let her remain there until she has purged herself a little through the inferior members, and that which comes out will be rather greenish. After she has thoroughly sweated, let her wash herself with the water of the previous bath, and thus let her cautiously enter her bed. And let this be done twice or three times or four times a week, and she will be found to be suﬃciently thin. We make for them a grave next to the shore of the sea in the sand, and in the described manner you will anoint them, and when the heat is very great we place them halfway into the grave, halfway covered with hot sand poured over. On Extracting the Dead Fetus  Those who labor excessively in giving birth to a dead fetus we assist thus. Let us place the patient on a linen sheet and let us have it held by four strong men at the four corners, the head of the patient a little bit elevated. We will make the sheet be pulled strongly this way and that at the opposite corners, and immediately she will give birth. On Retention of the Afterbirth  There are some women to whom the afterbirth remains inside after birth, to whom we give aid for its expulsion thus. Extrahamusb succum arthimesie, saluie, pulegii, per- siccarie, et aliarum herbarum huiusmodi, et faciamusc crispellas et demusd ad comedendum, et collocemuse eas frequenterf in balneis,g et predicto modo ad restringendumh sanguinem subuenimus.

Et rupturam sanamus cum puluere facto de simphito, id esto de consolida maiori et minori,p13 et cimino. Nevertheless, the juice itself has such a power that it is suﬃcient for expulsion. On Excessive Flow of Blood After Birth  There are other women who after birth have an immoderate ﬂow of blood, to whom we give aid thus.
