Another reason to get more light is because of the positive effect that natural light has on well-being. I can speak from some personal experience: After moving from an apartment with a bedroom that was dark all the time to an apartment with three windows that get morning sun, I can tell you that I am more rested, more ready to get up in the morning and more cheerful throughout the day.
Medical professionals are only at the beginning of this research, but so far, it looks like natural light can benefit homeowners in many rooms by reducing seasonal dips in mood, promoting healing, increasing productivity and more.
Natural light penetrates only so far through each window, so consider installing multiple points of light. You can also arrange your furniture so that the most-used pieces sit where there's the most light.
Getting light in is important to your health, studies say, but so is looking out your windows. Looking out at gardens brings faster healing in patients, claims a paper by HMC Architects. And if well-lit views help those who are sick, how much more will they help those who are well?
One study even showed that standardized test scores in students improved 26 percent when they got natural instead of artificial light at school.
If you're a stay-at-home mom or dad and spend a lot of time in the most-used room of the house, you want to make sure that your body can stay in tune with its biological clock. Being out of sync can mean fatigue, depression or what The Washington Postcalls a months-long case of jet lag.
