Keep the home cooler in warm weather.

Working night shift and want to sleep during the day.

4 reasons, not necessarily my reasons as I always raise my blinds.
Those are great answers, Lee! Thanks so much for your comment!
No, I know there are reasons that some people keep their blinds closed as mentioned above, but I only close mine at dark. I love the natural light and being able to see the trees and the outdoors during the day!!
That’s a very good reason to close them, at dark. You remind me of my sister. She love to keep the blinds and doors open to let the sunshine in! Thanks for your comment!
In the day I like to look at the River Medway. But at night I like to close it to keep out peeping eyes, I close it at night for Privacy. I close it at night for Security reasons. I can’t think of any 4th reasons or any other reasons.
Those are great reasons and thanks for sharing them with us!

Great answers, Hillary! Thank you for you answers!
