Does sleeping with one's head facing west and feet facing east affect a person's health?

It is not within our purview to address health problems. There is no شرعًا (Islamically) forbidden aspect in pointing one's feet eastward while sleeping, especially if one is in the Levant (Bilad al-Sham) and lying on one's right side, facing the Qiblah. For the etiquette of sleep and to avoid believing in the influence of stars, one can refer to fatwas numbered: 74291, 73917, 32562, 41556, and 32151. It is advised to consult the health consultation section of the network for more information.
