You need about seven hours of sleep to be productive. You can increase the chances of getting those by sleeping in a bedroom that is coloured blue, yellow, green, silver or orange.
Hotel booking site Travelodge studied 2000 British homes and found that those who slept in a blue bedroom were getting an average of seven hours and 52 minutes of sleep every night. The study authors think this is because blue is associated with calmness, and helps reduce blood pressure and heart rate.
Shades of yellow were the second best, clocking in seven hours and 40 minutes of sleep for inhabitants, closely followed by green (seven hours and 36 minutes), silver (seven hours and 33 minutes) and orange (seven hours and 28 minutes).
The worst colours were purple (five hours and 56 minutes), brown (six hours and five minutes) and grey (six hours and 12 minutes).
The study also had a few other cool findings:
• Couples who sleep in a bedroom that is decorated in a luxurious caramel décor make love on average three times per week. In contrast couples who sleep in a passionate red décor bedroom make love just once a week.
• Of those who have a blue bedroom, 58% reported they regularly wake up feeling happy.
• Of those who have a green bedroom, 22% reported they regularly wake up feeling upbeat and positive.
• Of those who have a silver decor in their bedroom, 21% reported they are more motivated to exercise in their bedroom.
The bottom line is that the colour of your bedroom can affect your sleep patterns as well as your consequent mood. It's probably a good idea to learn about colour theory and then see if you need to change your bedroom's colour.
Admittedly, 2000 British homes makes it a small and localised study, but the inferences have some good points that are still worth considering.
