Many people "hang bed curtains", mainly for shade. One of my classmates said that he slept lightly and was afraid of the light. His roommates are all very nice. Knowing that he sleeps very lightly, he usually uses his own desk lamp or even a computer, but he can't sleep even with the light on in the corridor, so he bought a shade cloth as a "bed curtain", which greatly improved the quality of sleep. At the same time, his roommate is much more convenient.
When you are lying in bed playing with your mobile phone, the bright light shines directly on you. When I want to sleep late, it will light up outside the window at 6 o'clock. When you want to take a nap but your roommate is still busy, you can't keep asking others to turn off the lights and draw the curtains as soon as you close your eyes. Then the best solution is to buy a curtain. Buy a half-open curtain to keep out the sun and breathe, which not only protects privacy but also does not affect communication with roommates.
At the same time, hanging bed curtains can protect personal privacy. Some people, especially girls, will feel more secure when they are fitted with bed curtains, and they can also prevent insects. On the one hand, it blocks the light. On the other hand, you can also have some independent space, such as keeping a diary. If you don't want to be seen or disturbed, you can close the curtains on the bed and isolate yourself from the outside world. Everyone has their own privacy space, some things can be put in the bed curtain, and some things can be done in the bed curtain, so it is unnecessary for a dormitory to face no privacy. Curtains are hung in the bedroom to keep out light and avoid light stimulation, which is helpful for sleeping. Burning the midnight oil does not affect roommates' rest. The pattern of the "bed curtain" should not be too complicated. Some patterns will show an indescribable appearance in dim light, which is not good.
