Colour Rendering Index (CRI) is the measure of how accurately a light source renders the colour of an object, when compared to sunlight. CRI100 is the highest rating. As the CRI increases, more shades of colour become apparent to the human eye. Like the apples in the adjacent images, details, contrast, and colours are enhanced. […]

Blood flow changes in the brain due to fatigue During sleep restriction there is reduced functional connectivity between the emotion regulation centre and the emotion processing centre. This increases emotional reactivity to negative stimuli.Generally, the frontal lobes provide inhibition to the amygdala. However, when the amygdala is activated, “amygdala hijack” can result in emotional overload
