First things first, figure out the amount of available space you have. Then decide on the number of things you can adjust and still make the room look awesome. Then third step is to figure out how you can actually improvise in utilizing the space with all those items.
So how do we start? Well, I do not know exactly what's your room like and how would you want it to be. But still, there's one thing you can always do in every room.
Switch Off the Lights While Sleeping. If you're one of those who cannot switch off easily, your bedroom should not get your grey cells and senses all worked up. Painting your room in a soothing palette and incorporating serene paintings as wall decor would give a relaxing feeling to your senses after a weary day. Moreover, experts recommend keeping your bed linen clean so that your sleep does not get disturbed due to unpleasant odour from the sheets. If you've got a sense of smell that would make you feel uneasy, make sure you use a detergent that does not offend your nose. Another alternative is to use vaporising essential oils that help to relieve stress and induce calm while sleeping.
