<p>Humidity is an important environmental factor that causes physiological changes in organisms. In humans, high humidity disrupts thermoregulation by limiting heat dissipation, leading to heat stress. While <i>Caenorhabditis elegans</i> lacks comparable thermoregulatory systems, humidity may still impact its heat tolerance by affecting cellular stress responses. We tested this by subjecting <i>C. elegans </i>to heat shock under different humidity conditions and found that lower humidity during heat shock improved survival<i> </i>compared to higher humidity. These findings demonstrate that humidity is an important variable affecting thermotolerance in <i>C. elegans</i> and should be standardized in heat-stress experiments.</p>
