Nattkomfort

Nattkomfort is a term used to describe the perceived comfort of a person during nighttime rest. It encompasses the physical conditions of the sleep environment, the comfort of bedding and sleepwear, and psychological factors such as stress and routine. The concept is used in both consumer product design, such as mattresses and pillows, and in sleep science to evaluate factors that influence sleep quality.

Key factors influencing nattkomfort include ambient conditions such as temperature, humidity, air quality, and ventilation, as well as light and noise levels. Bedding characteristics, including mattress support, pillow firmness, and fabric breathability, are central to perceived comfort. Personal factors also play a role, including body temperature regulation, age, health conditions, and sleep disorders, which can alter how comfortable sleep feels.

Practical recommendations commonly associated with nattkomfort include keeping the bedroom cool, dark, and quiet; aiming for a temperature around 16–19°C and humidity of about 40–60%; choosing breathable bedding and appropriate layering; maintaining a regular sleep schedule; and limiting caffeine, alcohol, and heavy meals close to bedtime.

Measurement and impact: nattkomfort is largely subjective and is typically assessed through sleep quality questionnaires and personal reports. Poor nattkomfort is linked to shorter sleep duration, reduced sleep efficiency, daytime fatigue, and impaired cognitive function. Ongoing research examines how environmental design, materials, and sleepwear influence sleep comfort, with implications for health, performance, and well-being.
