Sleeping and dreaming are commonplace. But some people often dream repeatedly while sleeping, and sometimes even wake up suddenly with their hearts pounding. What's going on here? What methods can improve sleep quality? 1. Why do we dream repeatedly? There is a period in sleep called rapid eye movement (REM), during which the body is in its most active state, with faster breathing and heart rate, and we are also prone to dreaming. At this stage, our brain activity will be as high or even higher as when we are awake. During the rapid eye movement phase, our eyes also quickly move back and forth in the orbit. The following situations may cause you to repeatedly dream: · Excessive pressure: Excessive pressure in work, study, interpersonal relationships, etc. may lead to repeated dreaming; ·Anxiety and melancholy: Anxiety and melancholy emotions may also lead to repeated dreaming; ·Physical discomfort or illness: Some physical discomfort or illnesses, such as stomach pain, headache, heart disease, etc., may also lead to repeated dreaming. 2. These sleep phenomena or "distress" signals emitted by the body during sleep can sometimes lead us to experience unpleasant dreams, such as repeated nightmares, physical pain or injury during dreams. These phenomena may be caused by the body sending out a "distress" signal, indicating that there may be some health issues. Repeated nightmares often indicate an unstable psychological state. Long term stress, anxiety, depression and other emotions can affect the quality of sleep, making us prone to nightmares. If there is physical pain or injury in a dream, it may also be that the body is sending out a "distress" signal. In this case, we may need to check for any physical issues. Suddenly waking up and feeling a rapid heartbeat or shortness of breath may also indicate that the body is' seeking help '. This phenomenon often occurs in dreams when there is an emergency or serious physical problem, and our body will automatically respond to this reaction. Reminder: When these situations occur, it is necessary to pay attention to our physical health. If these situations occur frequently, it is recommended to seek medical examination in a timely manner. What are the effects of poor sleep on the body? ·Deafness, tinnitus, and insufficient sleep can lead to insufficient blood supply to the inner ear, which can damage hearing. Long term staying up late may lead to deafness. ·Obese people who stay up late often eat "night snacks", which are not only difficult to digest, but also have a loss of appetite the next morning, causing nutritional imbalance, leading to obesity or fatty liver disease. ·Skin damage occurs when the skin enters a maintenance state from 10 to 11 pm. If one stays up late for a long time, their endocrine and nervous systems will be disrupted, resulting in dry, poor elasticity, dull and dull skin, and problems such as acne, pimples, and black spots. ·Memory decline: The sympathetic nervous system of those who stay up late remains excited at night, and during the day, they may experience lethargy, dizziness, memory loss, lack of concentration, and delayed response. Over time, problems such as neurasthenia and insomnia may also occur. ·The epithelial cells of gastric mucosa of people with gastrointestinal crisis need to be renewed once every 2-3 days on average, and generally at night.
