Neuroscientist Reveals What Living on the Moon Could Do to Human Mind

For generations, the moon has been a symbol of exploration and possibility. But if NASA succeeds in its goal of establishing a long-term base on the moon near the lunar South Pole, future residents may face a profound psychological experiment unlike anything humanity has experienced before.

A neuroscientist and other experts told Newsweek that daily life on the moon could reshape how people think, feel, and relate to one another, bringing both extraordinary opportunities for personal growth and significant risks linked to isolation, confinement, and separation from Earth.

NASA’s plans for a permanent lunar foothold have accelerated this year. In May, the agency unveiled a detailed roadmap for its Moon Base Program, outlining a three-phase strategy that culminates in “sustained human presence” on the lunar surface beginning in 2032. NASA described the final phase as the point when "living and working on the moon becomes a reality."

NASA’s own research suggests that the psychological demands of spaceflight are a serious concern. The agency says that isolation and confinement can lead to declines in cognitive and behavioral functioning. While “the robust set of behavioral health and performance countermeasures on ISS [International Space Station] have mainly been successful in mitigating this risk,” NASA warns that future missions beyond low-Earth orbit may face increased risks because traditional support systems are harder to provide.

A NASA-led study of astronauts on six-month ISS missions, published in November 2024 in Frontiers in Physiology, found that cognitive performance was generally stable overall, but detected periods of slower performance in areas including processing speed, attention, and working memory during flight.

The Risk of Isolation

Experts warn that the moon’s stark environment could weigh heavily on human mental health.

“A long-term lunar stay would challenge the nervous system in one of the most fundamental ways possible,” said Dr. Dave Rabin, a board-certified psychiatrist and neuroscientist who is the author of A Simple Guide to Being Alive.

Humans evolved in environments shaped by sunlight, gravity, natural landscapes, and social interaction, Rabin told Newsweek, and prolonged isolation could increase the risk of insomnia, anxiety, depression, irritability, and cognitive difficulties.

The neuroscientist described space as “psychologically brutal,” arguing that extended isolation can produce hallucinations, sleep disruption, and emotional distress. Although the moon may inspire wonder, he warned that “awe without belonging can become existential vertigo.”

In Rabin’s view, the greatest danger may not be boredom but becoming disconnected from the environmental signals that reassure people they are home.

"No casual reminder from the living world that you are part of something bigger than your own thoughts," the neuroscientist said. "That matters because the human brain evolved in natural, rhythmic, variable environments full of movement, sound, smell, light, and texture."

He compared a lunar settlement to “the ultimate sensory deprivation chamber with a view.” Without weather, wildlife, changing seasons, or familiar natural sounds, lunar residents could become increasingly inward-focused and reliant on artificial stimulation.

The Emotional Impact of Reduced Gravity

Researchers are beginning to understand how reduced gravity may influence emotional well-being.

Rabin noted that gravity serves as more than a physical force. Balance, posture, blood flow, sleep, movement, and spatial orientation all rely on gravitational input. While lunar gravity is not zero, it is substantially weaker than Earth’s.

"Over time, that could indirectly affect cognition and mood through changes in sleep quality, movement patterns, cardiovascular regulation, inflammation, vestibular processing, and the body's basic sense of groundedness," the neuroscientist said.

“The body evolved on Earth,” he said. “It remembers Earth even when the mind is trying to leave.”

Matt Grammer, a licensed professional clinical counselor supervisor (LPCC-S) and founder of Therapy Training, echoed those concerns. Grammer told Newsweek that a lunar settlement would remove many of the environmental cues people use to regulate mood and identity, including weather, greenery, familiar sounds, and ordinary daily rhythms.

Grammer said long-term confinement and isolation could increase the likelihood of anxiety, depression, irritability, emotional numbing, and decision-making difficulties. Unlike astronauts on the ISS, lunar residents would need to build a functioning society rather than simply serve as a temporary crew.

“On the moon, the mind might struggle less with fear than with the void of monotony,” he said. "Very simply, we humans need change. That might be through the weather, the seasons, nature, our community, and daily activities and routines. Without monotony, a moon resident will need to provide artificial cues-otherwise, the mind may come to perceive the environment as emotionally flat."

Defining a New Human Identity

Dr. Sam Zand, a board-certified psychiatrist who is the chief executive officer of Anywhere Clinic, told Newsweek he believes the greatest struggle for lunar pioneers will be maintaining their connection to one another.

“The most challenging experience of living on the moon would be the danger of prolonged confinement and separation,” Zand said. Drawing parallels with polar expeditions and space missions, he argued that humans require variety and normalcy to thrive. The psychiatrist said: “Our bodies adapt and adjust to new circumstances, but there is no guarantee that our psyche will follow.”

Without Earth’s changing environments, Zand said, future lunar habitats will need to recreate aspects of life on Earth to help residents to “feel connected to something greater than themselves."

Despite the risks, experts say humans are capable of adapting. But that adaptation may come with profound changes in identity.

Rabin said permanent lunar life would "eventually create a new kind of human identity-people who are biologically human, but culturally shaped by distance from Earth," which he says "could be fascinating in the short term, but strange, lonely, and spiritually destabilizing as well."

The neuroscientist said the central psychological question would be "do lunar settlers feel like pioneers expanding human possibility, or exiles separated from the only living world that made them?"

As NASA works toward sustained human presence on the moon, the challenge may prove to be not simply how to keep humans alive there, but how to help them feel human once they arrive.
