The astronaut will then reconstitute the food with liquid and eat it. “We have also created a self-heating pouch as we are used to warm food.” In space, this organisation is lost as there is no gravity. And because there is no physical activity to burn calories, “the microgravity isometric yogic exercises will take care of muculoskeletal problems, cardiovascular issues and mental stress and resilience”. According to Selvamurthy, the astronaut will be trained in yoga and meditation before take-off and perform at least 30 minutes of yoga each day in space to keep his bearings going. In microgravity, since there is always the fear of blood rushing in to the brain, he claims such exercises will help enormously.
