The harmful health effects of chronic, and toxic, stress have gained increased attention. However, less research has focused on the stress response in absence of toxic levels. This study examines the relationship between environmental and behavioral variations and cortisol levels throughout the day in healthy children. This study analyzed data from two cross-sectional studies. Salivary cortisol was measured over the course of a day in two months of one school year on forty-two 5th graders. The c...

Obstructive sleep apnea (OSA) is an important public health concern with numerous consequences at the societal level, including motor vehicle accidents, increased cardiovascular morbidity, metabolic dysfunction, and behavioral and cognitive deficit. OSA is characterized by a decrease in, or complete cessation of, airflow despite ongoing efforts to breathe, and is related to oxygen desaturation and sleep fragmentation....

In Vitro Fertilization (IVF) has been employed for more than four decades. A crucial concern is the etiology of infertility due to the fact that it may range widely, from reproductive system anatomy and endometrium receptivity to multisystem disorders and several immunologic factors. Among the immune pathologies that could compromise fertility are the autoantibodies affecting thyroid function. Infertile women are in a great prevalence of thyroid autoimmune disorders. However, there are still uns...

The interest in the human body physiological capacity to adapt to extreme heat and cold conditions has increased enormously in the last few decades because of global warming and the consequent changing temperatures. The human body has multiple thermoregulatory mechanisms to counter the external extreme temperatures whose main objective is to keep temperature homeostasis within normal values. As exposure time to these stressful conditions increases and the external temperature becomes even more e...
