The lighting of your house, first and foremost, will greatly affect your mood. Research indicates that poor lighting in your home can contribute to negative energy, depression and even vitamin D deficiencies. By contrast, good lighting will keep you and your loved ones in good spirits. Homes with open plan designs receiving lots of natural light can be especially good for keeping your family in a positive mood.
Lighting also affects your sleep cycle, as it can contribute to how alert you are in the morning and how tired you are in the evening. Typically, brighter lights are better for the mornings and dim lights are more appropriate for later in the day after the sun sets. The opposite lighting arrangement may leave your circadian rhythm puzzled, affect how you sleep and drain your energy day-to-day.
