Effects of Spaceflight on Human Skin

Area of Science:

• Space Medicine
• Dermatology
• Microbiology

Background:

• Spaceflight poses significant health risks, including various dermatological conditions.
• Astronauts report symptoms such as erythema, burning, itching, dryness, sensitivity, and skin thinning.
• Common issues include infections, abrasions, delayed wound healing, and accelerated skin aging.

Purpose of the Study:

• To review the interactions between the space environment and human skin.
• To highlight the impact of spaceflight on skin health and the skin microbiome.
• To discuss the implications of these changes for astronaut well-being.

Main Methods:

• This study is a review of existing literature on spaceflight and skin health.
• It synthesizes findings on dermatological changes observed in astronauts.
• It examines the role of the human skin microbiome in the space environment.

Main Results:

• Spaceflight induces multiple adverse skin conditions in astronauts.
• The human skin microbiome, unique to individuals, contributes to space station microbial ecosystems.
• Alterations in the skin microbiome during spaceflight can precipitate skin infections and exacerbate existing conditions.

Conclusions:

• The space environment significantly impacts skin health and the skin microbiome.
• Understanding these interactions is crucial for mitigating health risks for astronauts.
• Further research is needed to develop countermeasures for spaceflight-induced skin problems.
