Mariness Survey Identifies Causes of 'Rainy Season Malaise' and Sleep Discomfort

Survey Findings on Sleep Deprivation During the Rainy Season

Wellness brand 'mariness' conducted a survey on sleep deprivation during the rainy season, targeting men and women in their 30s to 50s who face sleep-related issues, as well as medical professionals.

During the rainy season (June-July), many people experience 'rainy season malaise'—characterized by feeling heavy and unrefreshed in the mornings. This is often linked not just to atmospheric pressure and humidity, but also to the sleep environment.
