Rather than taking individual daily figures at face value, users should mainly track long-term trends and shifts within their own baseline health.
New research shows how space travel affects women’s health.
The altered gravity and intense physiological pressures of space travel can rapidly disrupt key biological systems in women. A study published in Frontiers In Microbiology discovered that spaceflight conditions significantly change the protective vaginal microbiome, but leave the oral microbiome mostly unaffected. The findings highlight an urgent need for sex-specific research and targeted countermeasures to protect female astronaut health during long-duration space missions.
