2 LITTERATURE REVIEW is to natural illuminance and artificial illuminance from incandescent. (Rea and Figueiro, 2016) In the middle of the day, daylight is bright and rich in blue, stimulating the SCN, while sunset emits softer light and is dominated by orange and red perceived as relaxing and calming. (Figure 12) These changes happen because the sunlight is filtered by the atmosphere, natural- ly changing the angle of the sun according to the location, time and weather conditions. Seasonality in natural light is connected to longitude as the length of day and exposure to natural light is very different in Northern Europe compared to countries closer to the equator. As biological rhythms are a big part of the human functional system, this has a proven effect on the natural sleep/wake rhythm, mood and energy level. Circadian and infradian rhythms shape our lives and the way we behave: Days, weeks, months and years are rhythms we frequent without even thinking about it. A hypothesis could be that when living in the North, it is quite possible that following the seasons is a natural part of our annual rhythm. 2.7.1 Vitamin D Vitamin D3 can be obtained through food and nutrients and directly from the sun, dividing it into two groups: Calcitriol (D3) – metabolic system (kid- neys) and Soltriod (Vitamin D3) from sun and food. This will affect your sleep time, calcium + phosphate intake and by this your bone strength. It is one of the non-visual effects of light and the human body can self-regulate the intake, thus the level of Vitamin D will exceed healthy levels. Vitamin D is not absorbed from the sunlight but is a process in the skin. The synthesis is a response to ultraviolet light UVB rays from the sun (290- 315nm). (Stumpf and Privette, 1989; DeLuca et al., 2013; Tazzyman et al., 2015) These wavelengths should be effectively blocked by most glass types, but earlier in architecture the glass was allowing some UVB to enter the indoor space, as a direct effect of bringing daylight inside the house. Volf, 2013 states this ability as part of an unhealthieness factor of the window (p. 85). (Volf, 2013) Infrared rays do however penetrate most glass coatings, as you can feel the warmth from the sun. If the skin receives no direct sunlight and in addition you don’t eat supplementary foods to compensate, you can become deficient in Vitamin D accelerating negative effects on health and wellbeing, as ageing, high blood pressure, diabetes, kidney disease etc. (Caprio et al., 2017) 2.7.2 Connection to nature Biophilia has been connected to wellbeing and research in biological stim- uli for hospitalised patients has shown positive response to hospitalisation time. (Ulrich, 1984) [section 4.2.1] Findings suggest that work motivation, satisfaction and productivity has been linked to the ability to view nature from the work station. Windows with view can thus be a positive contribu- tion to wellbeing in staff as well as patients in the health care sector.
