What is the sign of insomnia?

Insomnia is very common in life, and both men and women may suffer from it. Long-term insomnia is also harmful to health, so there are some possible causes of insomnia, and existing diseases should also be paid attention to. For example, patients with heart disease, kidney disease, asthma, and ulcers are prone to insomnia. There are also some psychological and mental factors that can cause insomnia.

1. Insomnia caused by physical illness. The physical illnesses that cause insomnia include heart disease, kidney disease, asthma, ulcer disease, arthritis, bone and joint disease, gastrointestinal disease, hypertension, sleep apnea syndrome, hyperthyroidism, nocturnal myoclonus syndrome, brain disease, etc.

2. Insomnia caused by physiological changes in the environment will cause people to have physiological reactions, such as changes in the sleeping environment when riding in a car, ship, or airplane; strong light, noise, excessive cold or overheating in the bedroom may cause insomnia. Some people are highly adaptable to the environment, while others are very sensitive and have poor adaptability, and cannot sleep well once the environment changes.

3. Insomnia caused by psychological and mental factors Psychological factors such as anxiety, irritability, depression, and bad mood are all important causes of insomnia. The blows of life, the pressure of work and study, unfulfilled wishes and changes in the social environment can cause people to have psychological and physiological reactions, leading to abnormal function of the nervous system and brain dysfunction, thus causing insomnia.

4. Insomnia caused by taking drugs and other substances. Taking central nervous system stimulant drugs can cause insomnia, such as the diet drug amphetamine. If you take sleeping pills for a long time and quit, you will experience withdrawal symptoms - shallow sleep and frequent nightmares. Tea, coffee, cola drinks and other drinks contain the central nervous system stimulant - caffeine, which can cause insomnia if consumed at night. Alcohol interferes with a person's sleep structure and makes sleep shallower. Once you quit drinking, it will cause insomnia due to withdrawal reactions.

5. Insomnia caused by fear of insomnia. Some people have too high expectations for sleep, thinking that if they sleep well, they will be immune to all diseases, but if they sleep poorly, they will be prone to various physical problems. This excessive superstition about sleep increases the pressure of sleep and easily causes insomnia.
