It further helps if you switch on lights in the room you are actually in. There is little point in having the lights on in the bathroom if you are downstairs in the lounge.
Yep, it's nearly dark here, although I don't really mind, as I'll be picking my granddaughter up from college soon & we'll have a drive round to look at some of the Christmas lights.
When I get back I'll be lighting the candles too - nice & cosy.
Your question made me just look out of the window and its pitch dark! Its only 4.20 and it looks like the middle of the night. I am in central Scotland.
