The Impact of Sunlight on Adventitious Buying and Giving.

The impact of sunlight on the income derived from spending and donations in a coastal charitable facility is examined. Data consisted of income during 2017 and 2018, together with daily sunshine hours and apparent temperature, and a multiple linear regression model was employed to determine the importance of these meteorological variables on income. Results indicated that income increased with both increasing sunshine hours and apparent temperature, but with an interaction effect (negative coefficient) between sunlight and apparent temperature such that the effect of sunlight on income is positive at lower apparent temperatures and negative at higher apparent temperatures. So, besides its many direct and indirect effects on man, it appears that sunlight also acts as a positive driver in adventitious giving and buying.
