So a warmer light helps with people&amp;#x27;s circadian rhythm in preparing for sleep. Remember that light at sunset also becomes warmer.&lt;p&gt;If all your indoor lighting was 5000K, then it would be like you would be living your indoor life constantly at noon.&lt;p&gt;It&amp;#x27;s why software like f.lux was created (and the functionality has been incorporated into some OSes as well).</text></comment>
