How Lighting Affects Us

Unveiling the hidden force shaping our lives Light is more than just something that illuminates our surroundings. It's a powerful force that directly impacts our mood, behaviour, and even our physiology. From the warm glow of a sunrise to the cool blue of a computer screen, the type of light we're exposed to can subtly influence how we feel and act.

Regulating Our Internal Clock

Our bodies have an internal clock known as the circadian rhythm, which regulates our sleep-wake cycle and other vital function This rhythm is largely controlled by light exposure. Natural sunlight, with its high levels of blue light, signals to the body that it's daytime, promoting alertness and wakefulness. Conversely, darkness triggers the production of melatonin, a hormone that promotes sleep.

The Mood Spectrum

The type of artificial light we use indoors also plays a significant role in our mood. Bright, cool-toned lights, like tfound in offices and classrooms, can increase alertness and concentration. However, prolonged exposure can lead to anxiety and stress. Conversely, warm-toned lights, like incandescent bulbs or dimmer switches, create a more relaxed and calming atmosphere, making them ideal for bedrooms and living rooms. Beyond intensity and temperature, the colour of light can also affect our mood and behaviour. For example, red light is often associated with excitement and passion, while blue light is known to induce feelings of calmness and peace. Greenlight is often considered calming and refreshing, while yellow light can boost energy and mood.

Creating the Right Atmosphere

Understanding light's psychological and physiological effects is crucial for creating the right atmosphere in different space Restaurants often use warm, dim lighting to create a romantic and intimate ambience. Conversely, hospitals and clinics often use bright, cool-toned lights to promote alertness and vigilance among staff.

The effects of light extend beyond our emotional state. Studies have shown that exposure to natural light can improve our sleep quality, cognitive function, and even immune system response. Conversely, inadequate light exposure can contribute to seasonal affective disorder (SAD), a type of depression that typically occurs during the winter months when daylight hours are shorter.
