The main manifestations of insomnia are difficulty falling asleep, waking up easily during the night and falling asleep again, and maintaining little sleep time, which are the end result of many complex factors. Adjustment of sleep can start from the following aspects: sleep habits. The first thing is to have a regular routine. The length of sleep varies from person to person, so you should not deliberately pursue the length of sleep and feel good when your energy is restored. Maintaining good sleep habits is the first step that must be taken. In addition, insist that exercise will help with sleep, but avoid it within two hours before bedtime. Always turn off the lights, draw the curtains and keep quiet at night before going to bed, try to relax yourself, let go of all your worries, take a hot bath or listen to soothing music will be helpful for sleep. Don’t eat or drink a lot before bedtime or put yourself in a state of hunger. Medication effects. If you usually have a regular medication, you need to pay attention to whether there is some kind of excitatory substance in the medicine to affect sleep. Alcohol and tobacco are also exempt, because the nicotine in cigarettes can make people excited, and alcohol can also disrupt sleep. Adjust your mindset. Reduce their own psychological burden, find the source of psychological stress, and strive to solve the things that can not be put, if necessary, counseling. If insomnia persists through these three adjustments, you can choose to take oral sedative-hypnotic drugs, but be careful to follow the principles of individualization and on-demand medication, and follow medical advice.
