What causes dreams?

　　Many people have had this experience: they have one after another dreams at night. When they wake up, they clearly remember the plot of the dream, but they feel weak and listless during the day. Long-term dreaminess not only affects sleep quality, but also interferes with daily life, making people wonder: What causes dreaminess? In fact, this phenomenon is closely related to physiological, psychological, environmental and other factors.

What causes dreams?

　　1. Excessive emotional stress

　　This is the most common trigger. Work anxiety, academic pressure, interpersonal conflicts, etc. in life will keep the brain in a state of tension during the day and still cannot fully relax at night. Active thinking can easily lead to a large number of dreams. Especially when you are in depression, anxiety and other emotions, the phenomenon of dreaminess will be more obvious.

　　2. Poor sleeping environment

　　A noisy sleeping environment, too bright light, and too high or too low temperature will interfere with the normal sleep cycle and cause people to frequently wake up in the light sleep stage. Light sleep is a period when dreams are most common, which in turn makes people feel like they have more dreams. In addition, improper sleeping posture, such as sleeping on your stomach that puts pressure on the chest, may also stimulate the brain to produce dreams.

　　3. Irregular eating and resting schedule

　　Overeating before going to bed, consuming spicy foods, or drinking coffee, strong tea, alcohol and other beverages will increase the burden on the gastrointestinal tract or stimulate the nervous system, leading to shallow sleep and more dreams. Staying up late for a long time, reversing work and rest, disrupting the biological clock, will also affect the sleep structure and cause excessive dreams.

How to improve the problem of excessive dreams

　　1. Regulate emotional state

　　Release stress during the day through exercise, meditation, talking to relatives and friends, etc., and avoid falling asleep with strong emotions. Before going to bed, you can listen to soothing music and take a warm bath to help your brain relax and reduce active thinking.

　　2. Optimize sleep environment

　　Keep the bedroom quiet, dark, and at a suitable temperature (generally 18-22°C is ideal), and choose comfortable pillows and mattresses. Stay away from mobile phones, computers and other electronic devices an hour before going to bed to avoid blue light stimulating the brain.

　　3. Develop a good routine

　　Set a fixed bedtime and wake-up time every day, even on weekends, so your body clock won't be disrupted. Avoid eating and drinking stimulating drinks 2 hours before going to bed. You can drink an appropriate amount of warm milk to help you sleep.

　　Excessive dreams are not a trivial matter of "not sleeping well". Only by identifying the cause in time and adjusting it can you have high-quality sleep and lay a solid foundation for good health.
