Inadequate exposure to natural light during the day and overexposure to artificial light at night can make one sick, demonstrates a new study.
Richard Stevens from University of Connecticut asserted that it had become clear that typical lighting was affecting their physiology but lighting could be improved.
Stevens continued that they were learning that better lighting could reduce these physiological effects and by that they meant dimmer and longer wavelengths in the evening and avoiding the bright blue of e-readers, tablets and smart phones.
As smartphones and tablets become more commonplace, Stevens recommends a general awareness of how the type of light emitted from these devices affects their biology.
The study is published in the British journal Philosophical.
