What Living on the Moon Could Do to the Human Mind

NASA wants to build a base near the moon's South Pole and have people living there by 2032. It sounds exciting, but scientists warn that life on the moon could be very hard on the human mind. A neuroscientist — a doctor who studies the brain — and other experts say that being far from Earth, cut off from nature, and living in a small space could seriously affect how people think and feel. Understanding these risks may be just as important as building the rockets to get there.

NASA has been working toward a permanent home on the moon for several years. In May, the agency shared a three-step plan for its Moon Base Program. The final step, set to begin in 2032, is when 'living and working on the moon becomes a reality,' according to NASA. The agency already knows that the mental challenges of space travel are serious, and it has warned that missions far from Earth will be harder to support than trips to the International Space Station (ISS).

A study published in November 2024 looked at astronauts who spent six months on the ISS. Researchers found that while most cognitive performance — meaning how well the brain works — stayed steady, there were times when astronauts processed information more slowly. Their attention and working memory also showed dips during the flight. This gives scientists a preview of what longer missions, like living on the moon, might do to the brain.

Dr. Dave Rabin is a psychiatrist and neuroscientist who wrote a book called A Simple Guide to Being Alive. He told Newsweek that a long stay on the moon 'would challenge the nervous system in one of the most fundamental ways possible.' Humans grew up over thousands of years in places filled with sunlight, open land, and other people. Without those things, Rabin says people on the moon could face insomnia, anxiety, depression, and trouble thinking clearly.

Rabin compared a lunar settlement to 'the ultimate sensory deprivation chamber with a view.' On the moon, there is no weather, no wildlife, no changing seasons, and no familiar sounds from nature. Without these everyday cues, moon residents might turn more and more inward, relying on screens and artificial environments to feel something. Rabin warned that even being amazed by the view could start to feel empty without a true sense of home.

Gravity also plays a bigger role in our mental health than most people realize. The moon's gravity is much weaker than Earth's, and Rabin says that affects far more than just how much you weigh. Balance, sleep, blood flow, and even your sense of where your body is in space all depend on gravity. Over time, these changes could affect mood and thinking through shifts in sleep quality and how the body processes its surroundings.

Matt Grammer is a licensed counselor and founder of Therapy Training. He agrees that the moon's environment would strip away many of the things people use to feel like themselves — things like rain, green plants, familiar sounds, and the rhythm of daily life. Grammer said that long-term isolation on the moon could lead to anxiety, depression, emotional numbness, and difficulty making decisions. He noted that moon residents would face a challenge that ISS astronauts do not: they would need to build an actual society and live in it for the long term.

Dr. Sam Zand is a psychiatrist and the CEO of Anywhere Clinic. He believes the hardest part of living on the moon would be staying connected to other people. He compared a lunar base to polar expeditions and long space missions where people live in tight spaces for months. 'Our bodies adapt and adjust to new circumstances,' Zand said, 'but there is no guarantee that our psyche will follow.'

Despite all these risks, experts say humans are capable of adapting to new environments. But that adaptation may change who people are at a deep level. Rabin said that people who live long-term on the moon would likely develop a new kind of human identity — 'people who are biologically human, but culturally shaped by distance from Earth.' He called this both fascinating and potentially lonely.

NASA's biggest challenge may not be building a lunar base or keeping people physically safe. It may be figuring out how to help people on the moon still feel human. Scientists, psychiatrists, and counselors are already working on that question. If humans are going to live on the moon, they will need to bring more than food and oxygen — they will need to bring a sense of home.
