The UV Shield: Science of High-Altitude Sun Protection

Blocking Cosmic Rays During Your Mount Everest expedition

Radiation at 8,848m

At the Mount Everest summit, the atmosphere is too thin to filter out high-energy cosmic rays. Understanding the physics of radiation is vital for choosing the right protective gear for your Mount Everest expedition.

The Impact on Optical Health

High-altitude UV can cause cataracts and macular degeneration. Every Mount Everest summit climber must use Category 4 lenses that block 99% of infrared and ultraviolet light during the expedition. Everest trekking safety starts with the eyes.

The Fabric Defense

Standard t-shirts have low UPF ratings. Professional Everest trekking gear is chemically treated to block radiation, ensuring your skin is protected from the intense sun during the approach to Everest Base Camp.

Nose and Ear Guards

The ears and nose are most prone to radiation burns near the Mount Everest summit. Using specialized glacier glasses with leather side shields and nose guards is a standard Mount Everest expedition safety protocol.

Armor Against the Sun

The sun is as lethal as the cold near the Mount Everest summit. Prioritize UV-rated gear to ensure your Mount Everest expedition is both safe and comfortable.
