Our DeltaREM team decided to face the SLEEP SHIFT SCHEDULING TOOL challenge in the SUSTAIN category by addressing the objective of developing, programming and deploying a web application that allows three main functions:
1) To evaluate the quality and quantity of sleep
2) To elaborate a nutritional plan of 4 times with individual caloric requirement
3) Develop an exercise routine based on rest / fatigue.


Sleep has a direct impact on the quality of life and work performance of all people, being able to favor the appearance of accidents derived from poor sleep hygiene accompanied by an alteration of the circadian cycle. Astronauts get to experience 15 sunrises in 24 hours on the International Space Station as it rotates around the world, so fixed times are established to sleep according to circadian cycles and allow them to sleep around 8 hours a day.
We also propose the use of two tools created by us:
1. "BandHz" that will provide us with data to evaluate REM sleep. And it will allow to eliminate the light from the environment to favor the regulation of the circadian cycle.
2. "FrequencyHz" that will contribute to exercise routines through neuromuscular microstimulations to avoid the loss of muscle mass.

We made a review of the foods available on the ISS as well as their nutritional information, in this way different cyclical menus are proposed that meet the nutritional requirement for astronauts.

Based on the existing equipment in the ISS to exercise (tradmill, cycle ergometer, ARED) we propose 7 cyclical routines that emphasize anti-gravity muscle groups.
According to the physiology of the circadian cycle, we propose a routine with fixed fields (time to wake up, breakfast, snack, lunch, dinner, EVA collation) and editable fields (Time of scientific experiments, review of protocols in the ISS).
Analyzing REM sleep by recording various variables (heart rate, respiratory rate, temperature, rapid eye movements, among others), we propose quality improvement points in sleep hygiene.
