The main reason why you can’t sleep when you are traveling is because the brain’s defense mechanism is activated. Once the environment changes, coupled with business travel, the amount of exercise may increase, the routine will also change, may prompt the cortex to increase the factors of excitation, when the center of mental activity – the cortex is in a state of excitement, will be excited message to the brainstem reticular body, stimulate the brainstem reticular body activity, and this stimulus will be transmitted back to the cortex, so the cortex is more excited, so that the more you want to sleep, the more you can’t sleep. In addition, the results of the study show that some people do not sleep well in unfamiliar environments, possibly because one hemisphere of the brain stays relatively awake during sleep to guard against potential dangers, and once there is an unfamiliar disturbance, it will wake up the sleeper. There are also some people due to personal growth experience, lack of security, or for sensitive and suspicious character traits, easy to produce psychological discomfort, the phenomenon of recognition of the bed can not sleep. If you know that you have bed-recognition behavior, you can develop an established pattern of behavior in normal times to overcome the discomfort brought about by changing beds or environments. Such as brushing teeth, reading, freshening up before going to bed, telling the cerebral cortex “to rest”. You can also bring your own pillow or other items on the bed with you on business trips and travels, choose a quiet, cozy hotel with an environment similar to the layout of your home as much as possible, don’t get overly tired or overly excited, and learn to relax yourself to help alleviate the behavior of bedwetting.
