Interior lighting of the building

Interior lighting is one of the most crucial elements in designing living and working environments, profoundly affecting the beauty, functionality, and comfort of a space. Appropriate lighting can transform the atmosphere, enhance spatial efficiency, and even influence individuals’ mental and physical well-being.

In interior lighting design, providing sufficient illumination for daily activities is essential, alongside considering aesthetic aspects. Proper use of light can highlight architectural features, accentuate specific points, and create a pleasant and calming ambiance.

The impact of interior lighting on human mood

Interior lighting is one of the most crucial factors in creating a pleasant space that influences human mood. Light not only allows us to see our surroundings but also affects our emotions, mood, and even cognitive performance.

• Biological Clock: Natural and artificial light influences our biological clock, helping to regulate the sleep-wake cycle. Daylight reduces melatonin production (the sleep hormone), boosting energy and alertness.
• Emotions: The color, intensity, and direction of light can affect our emotions. Warm and soft light creates a sense of relaxation and security, while cold and intense light may increase feelings of anxiety and tension.
• Cognitive Performance: Studies have shown that adequate and proper lighting can enhance cognitive functions, improving focus and learning efficiency.
