Purpose: Explain how cabin humidity affects sensory perception and overall well-being
The Objective
The effects of low cabin humidity extend beyond comfort, influencing taste, smell, and overall well-being.
The objective was to explain these impacts clearly and in a relatable way, helping audiences understand how environmental conditions affect sensory experience and health.
My Approach
I developed the article with a focus on sensory impact and educational storytelling.
The content connects humidity levels to how the human body perceives taste and smell, translating technical factors into familiar experiences. By focusing on sensory changes, the article makes the topic more engaging and easier to understand.
The tone balances scientific credibility with accessibility, ensuring relevance for a broad audience.

Ever wondered why food and drinks taste bland on airplanes? The answer lies in the ultra-dry cabin air, which not only dulls your senses but can also affect your health. Discover how low humidity levels in aircraft cabins impact your taste, smell, and overall well-being—and how CTT Systems’ Humidifier Onboard can transform your in-flight experience.
The science behind dry air in airplane cabins
Airplane cabins are notorious for extremely low humidity, often as low as 5%—far below the comfortable 30–50% found indoors on the ground. This dryness is caused by the cold, arid air brought in at cruising altitude, which quickly evaporates moisture from your skin and body, leading to dehydration.
How low humidity affects your senses
- Nasal passages: Dry air dehydrates the mucous membranes in your nose, impairing olfactory receptors and making it harder to detect aromas. Since much of what we perceive as taste is smell, this significantly dulls the flavour of food and beverages.
- Mouth: Reduced humidity decreases saliva production, making it difficult for taste buds to interact with food molecules. This results in a blander taste, particularly for complex dishes and drinks like wine.
Why do food and drinks taste different in the air?
The combination of dry nasal passages and mouth means your sense of taste is diminished by up to 30%. Sweet and salty flavours are particularly affected, making meals seem bland and less enjoyable. Airlines often add extra salt and sugar to compensate, but this can have negative health implications for frequent flyers.
Health implications of low cabin humidity
- Dehydration: Dry air and salty foods can worsen dehydration, leading to discomfort, fatigue, and headaches.
- Excess salt and sugar: To boost flavour, airlines often increase the amount of salt and sugar in meals, which, when consumed frequently, raises the risk of high blood pressure, cardiovascular issues, and even diabetes or obesity.
The solution: Humidifier Onboard for healthier, tastier flights
CTT Systems’ Humidifier Onboard restores healthy humidity levels in the cabin, keeping your nasal passages and mouth hydrated. This enhances your ability to enjoy the full flavours and aromas of in-flight meals and beverages, reduces the need for added salt and sugar, and supports overall passenger well-being.
