CryoPod would be similar to an induced hibernation, putting you in a sort of “comatose state” whilst onboard the shuttle. It is similar to getting frozen; a child falls into a frozen lake and gets induced hypothermia which shuts down all but his vital organs, leaving him in a short coma until he wakes up with no side effects. The same thing can be said about skiers trapped in avalanches. According to a research article by NASA,  Humans who eat a balanced diet while confined to bed rest for 90 days lose a little more than half of their muscle strength.  A balanced diet can easily be administered through an IV drip. Most likely, you will not be able to fully sleep through the flight until the technology has vastly improved, but you will go in and out of statis every two weeks, according to Spaceworks, a leading company in this field.These and the rest of the electronics on the ship will be Solar Powered. When in space, the presence of the sun can amplify the solar power, but even so, as a backup plan we have Artificial sunlight, which is actually created by lasers and LED lights.
