Choose The Right Curtains
This is another tip that might seem counter-intuitive. You might think the best choice for curtains are any kind that block the light – namely, dark, thick curtains. However, that’s exactly the opposite of what you should be using. The dark curtains actually attract heat, therefore making the room warmer. For the summer months, you’ll actually want to invest in some linen curtains in neutral colors. These curtains may let in the light, but they won’t attract the heat!
