Today is the Winter Solstice and the shortest day of the year. It’s a good time to reflect on how lighting effects our mood and how we feel.
Poor lighting can cause eye fatigue and headaches which make us feel depressed or ill. Our bodies need a good quantity of light at the right intensity and at the right time of day to act as cues for our internal body clock. Light in the morning helps us wake up and feel alert and energized while dimmer light at night cues us to go to sleep and stay asleep. “Light is critical for our health and well-being. Ensuring that we receive adequate light levels at the appropriate time of day benefits our alertness, mood, productivity, sleep patterns and many aspects of our physiology” says Dr. Victoria Revell, a chronobiologist at the University of Surrey.
