“…NASA has indicated that mood disorders of astronauts include depression, irritability, anxiety, and frustration. These conditions are regarded as the most severe threats to the space missions, since they compromise the ability of the astronauts to perform tasks under pressure [119], [120]. Several studies have shown that negative as well as extreme positive feelings along with cognitive workload affect behavior, decision-making and performance in extreme environments [121], [122].…”

“…Several studies have shown that negative as well as extreme positive feelings along with cognitive workload affect behavior, decision-making and performance in extreme environments [121], [122]. In addition, sleep deprivation and decreased quality of sleep are common in space missions and can result in performance degradation and both cognitive and mental problems [120]. These are reflected in reduced response time and working memory, higher error rates and reduced visual alertness.…”

Mood disorders affect more than 300 million people worldwide and can cause devastating consequences. Elderly people and patients with neurological conditions are particularly susceptible to depression. Gait and body movements can be affected by mood disorders, and thus they can be used as a surrogate sign, as well as an objective index for pervasive monitoring of emotion and mood disorders in daily life. Here we review evidence that demonstrates the relationship between gait, emotions and mood disorders, highlighting the potential of a multimodal approach that couples gait data with physiological signals and home-based monitoring for early detection and management of mood disorders. This could enhance self-awareness, enable the development of objective biomarkers that identify high risk subjects and promote subject-specific treatment.

“…It may affect the health of astronauts, so the safety of the mission would be endangered. Six causes for sleep alterations might be (1) factors related to cabin environment, (2) schedule adjustment, (3) impaired sleep discipline, (4) disordered circadian rhythm, (5) unreasonable work arrangement, and (6) mental and/or physical factors [50].…”

Fads and Facts About Vitamin D

Mankind has explored space since many years ago for distinct purposes. The space environment has its special features including microgravity (weightlessness), radiation, vacuum, and extreme temperature. It is fascinating to hear space traveling or even living on another planet, but it may cause dramatic changes in the human body. The skeleton has the primary role for the human body on the Earth and also in space. Osteoporosis is the principal feature in spaceflights occurring sooner or later. It will pose health risks. The aging of the population is the cause for osteoporosis to be more prevalent in the future. It seems that aging will happen sooner in space for human beings that are accustomed to living on the Earth. A complex of all reported changes that would occur in space, the picture of a closely resembling aged man emerges. Vitamin D can be synthesized and acts as a hormone. Its receptors are evident in more than 30 human tissues. Vitamin D has positive effects on the skeleton and other systems of the body in many regards. Multiple actions have been claimed for vitamin D (real or false), many aspects of which are not fully understood. The issue applies more about the vitamin and space, which has been tried to describe in this chapter.

“…The countermeasures suggested by Wu et al [ 2 ] do not reduce the cosmic ray induced eye interactions. During a deep space mission, astronauts are exposed to galactic cosmic radiation (GCR) as well as solar particle events (SPEs) [ 12 – 15 ].…”

“…The findings of a recent National Aeronautics and Space Administration (NASA)-funded study published in the Lancet Neurology journal showed sleep deficiency in astronauts not only during space shuttle and International Space Station (ISS) missions, but also from the start of a three-month preflight training interval [ 1 ]. Wu et al recently published an article entitled “On-orbit sleep problems of astronauts and countermeasures” have addressed the issue of sleep in space as a new medical research frontier [ 2 ]. In their review, the authors discussed the sleep problems of astronauts.…”

This commentary addresses the article by Wu et al. entitled “On-orbit sleep problems of astronauts and countermeasures”. In this article, the authors discussed the sleep problems of astronauts. Despite its challenging topic, the paper authored by Wu et al. has at least one major shortcoming. This issue is related to the observation that the sleep pattern of astronauts can be disturbed by light flash phenomenon. Since the first report by astronaut E.E. Aldrin in 1969, many astronauts have reported light flashes. These visually perceived flashes of light occurred in different shapes but they apparently moved across the visual field of astronauts and possibly caused, at least to some extent, sleep problems. Moreover, the countermeasures proposed by the authors may improve astronauts’ sleep pattern, but they do not address the root cause of the light flashes (i.e., heavy ion interactions outside the shielding provided by the Earth’s magnetosphere). A possible approach to reducing light flashes is available using the fact that much of the galactic cosmic radiation (GCR) spectrum is composed of ions that can be diverted from the spacecraft using electromagnetic fields. Possible design parameters and the requisite electric and magnetic field strengths to successfully deflect GCR radiation are outlined.
