Sleep, rest, and relaxation are often undervalued factors that contribute to the maintenance and improvement of wellness. Sleep cycles and their given durations have been clinically proven to influence essential aspects of human life: cardiovascular health, metabolic health, mental health, immunologic health, human performance, and mortality, to name a few [1]. Inadequate sleep has known associations with increased risks of mortality, cardiovascular disease, cerebrovascular disease, obesity, diabetes, cancer, and depression. Rest, in the context of this chapter, is not necessarily synonymous with sleep – for instance, sleep can still occur without rest and its improvements on overall functioning [2]. Relaxation often corresponds to feelings of peace, comfort, body laxity, mental laxity, and positive emotions. Relaxation as a wellness tool can take a variety of forms, such as abdominal breathing and progressive muscle relaxation techniques [3].

While wellness is a concept that has no universally accepted definition [1], researchers have been able to determine eight dimensions crucial to wellness: physical, emotional, social, spiritual, intellectual, financial, occupational, and environmental [2]. The physical dimension includes physical health, self-image, body image, and appearance. The notion of “look good – feel good” has been gaining traction, and there is emerging scientific evidence supporting it [3, 4]. This chapter focuses on the popular aesthetic techniques of cosmetic procedures and styling, in addition to how such aesthetic techniques can improve overall wellness during and after recovery from surgical, medical, and psychiatric illness.
