This set of simple yet effective solutions can solve the problems faced by astronauts easily, without the need to implement huge changes. In space, astronauts may not be able to get a good sleep due to several reasons as mentioned below.

Our solution is aim provide astronaut a healthy lifestyle by solving their sleep dilemma. The solutions are taken from normal daily life. Being a astronaut is not easy and it is risky. We hope to achieve a goal where anyone who dreams to become an astronaut do not have to worry about their well-being on space.

Our solutions:

1.Create own timezone. By turning on and off the light of the sleeping space, a timezone can be created for an astronaut. Turning on warm yellow light indicates "day" while turning off the light indicates "night". To perform this, please ensure the sleeping space of astronaut is an enclosed room so that the sharp light outside will not affect the astronaut's sleep.This creates a healthy daily regimen for astronauts based on the timezone. The wall of the sleeping space should be embedded with soft materials that absorb sound because the loud sound of machine operating will disturb sleep. The sleeping space should be large enough for the astronauts to turn over their body when they sleep.

2.Sleeping shift schedule. All the astronauts should sleep according to the shift. For example, 50% of the astronauts work on day shift while the other 50% work on night shift to support mission console.

3.Use tracking watch and apps. To ensure all the astronauts get 8 hours of quality sleep, an app that can track sleeping behavior is vital. The tracking watch will vibrate to wake them up. Sometimes, astronauts will have light sleep before they move into deep sleep or tend make a dream in their sleep before they awake. Thus, an app is required to track the sleeping behavior of astronauts. Every astronaut should wear a tracking watch so that they only wake up after 8 hours of deep sleep to ensure they have enough rest.

4.Develop perishable food. To make sure all the astronauts get sufficient nutrient, the space food(vacuum packed food, dried food and packed liquid food) should includes all types of nutrients such as protein, carbohydrates, minerals, fats and minerals. Every astronauts have different health condition. Thus, AI app should be used to design the nutrient plan(breakfast, dinner, lunch) for each astronaut according to their health and need.

5.Develop workout tool. Exercising is very vital for astronauts. Without exercising, the astronauts' bones would be more fragile and their muscles weaker after spending some time in space due to microgravity. They could also experience a major loss in bone mass, bone density and their cardiovascular health would be affected. Thus, resistance band and TRX band anchored to the spaceship wall should be available for astronauts to do their workout efficiently. A customized plan should be generated using AI software or technology according to the health of every astronaut. It is due to the reason that every astronaut has different body conditions.
