Long-term cryogenic and hibernative sleep may be the key to getting humans to Mars — and beyond. But with research and funding active concerns, it may first come to a spa near you.
Our bodies aren't meant for space. It's heartbreaking for science fiction fans to hear, but it's also a self-evident fact. Our bodies require too much maintenance to speed through the stars. We need a steady supply of those things absent from space —namely water, food and oxygen. We crave warmth but won't find it in deep space, where the average temperature is minus 455 degrees Fahrenheit.
Even if we could survive in an icy vacuum without sustenance, we'd probably go insane without distractions and room to move. In 2013, participants in a 17-month Russian spaceflight simulation became depressed and lethargic in the cramped quarters. They grew desperate for privacy and often skipped exercises that would be crucial during a real spaceflight.
Ensuring space travellers stay healthy and active during long flights is a puzzle with two pieces: cargo and weight. Food, water, exercise equipment and televisions are heavy. Fuel is expensive and volatile. The more weight you're bringing into space, the more fuel you need. But aeronautic engineers (of SpaceWorks) believe they have found the key to solving that puzzle: put your space travellers to sleep.

Weight is still very relevant until it is in space. If food and water systems for us to be awake are lighter than the freezer for cryogenic sleep then the logistics of launching are easier if we are awake and bored.

No, weight isn't important at all. Only Americans think it is, because they cannot understand mass due to their unit system and poor education.
What's important is MASS. Even in space with zero-g, mass has inertia; more mass requires more thrust and more fuel to move around.
