Appropriate exercise helps improve sleep quality.

　　Sleep is the most powerful way for the body to maintain health. To sleep well, you must follow sleep patterns and create good sleeping conditions.

　　Sleep disorders and physical or mental illnesses can sometimes be cause and effect of each other. It’s important to distinguish between them, identify the root cause, and determine whether poor sleep causes illness or illness leads to poor sleep, so that appropriate treatment can be applied.

　　Yang Gaiqing, director of the First Ward of the Department of Neurology at Zhengzhou Central Hospital, explains that people experiencing sleep problems should look for causes in three aspects. First, check for any chronic diseases such as high blood pressure, diabetes, or neurasthenia. These conditions can affect the body and, in turn, impact sleep. If you have such chronic diseases, it's important to treat or manage them actively, which can help improve sleep quality. Second, consider whether there has been a traumatic event that hasn’t been properly addressed, such as psychological trauma. Traumatic events can impair one’s ability to self-regulate mentally. Normally, falling asleep simply requires lying quietly in bed with a calm mind, allowing the brain and body to gradually relax and enter sleep. But for those who’ve suffered psychological trauma, the mind remains tense. The brain races, unable to let go of many thoughts. They often feel mentally unbalanced, constantly worrying about the future, distressed, anxious, as if a disaster is imminent, feeling fearful and nervous, disrupted by anxiety, depression, worry, frustration, tension, and fear—making it nearly impossible to fall asleep, or if they do manage to sleep, it’s fitful. Even when extremely tired, they can't sleep well. Third, learn to relieve stress, ease tension, and balance work and rest. Doing these things will naturally lead to better sleep quality.

　　Create a Good Sleep Environment

　　Zhang Xiaoman, director of the Second Ward of the Department of Neurology at Zhengzhou First People’s Hospital, says that a good sleep environment should provide a sense of safety and pleasure, and allow full physical and mental relaxation. This includes a quiet surrounding environment, fresh air, and suitable indoor temperature and humidity. The lighting and color tones indoors should align with the season and your mood. Also, bedding matters—for example, the proper use of pillows and quilts. Choosing or using the wrong pillow can make you more tired the longer you sleep. Pillow selection and use are quite particular: don’t choose one that’s too high or too hard, and pick different materials according to the seasons to ensure comfort. The pillow should support the neck—if the neck is left hanging, it’s hard to rest well. Quilts shouldn’t be too heavy; opt for breathable, comfortable ones. It’s best to sleep in the dark because long-term exposure to light at night can disrupt the biological clock that regulates metabolism, not only affecting sleep but also leading to illness. Most importantly, everyone should establish a reasonable daily routine based on their own lifestyle and work schedule, and accurately recognize the body’s signals that it’s time to sleep. This helps you fall asleep more quickly. In short, creating a cozy bedroom atmosphere along with good sleep habits will naturally lead to better sleep.

　　A restless stomach leads to restless sleep. Yang Gaiqing reminds us that diet plays an important role in getting good sleep, especially dinner. Avoid eating too much, too greasy, or too stimulating food, and don’t drink strong tea, coffee, or alcoholic beverages. Caffeinated drinks or foods stimulate the nervous system, boost energy, increase heart rate and breathing, raise blood pressure, and caffeine also acts as a diuretic, causing frequent nighttime bathroom trips that disrupt sleep. Drinking alcohol before bed may help you fall asleep quickly, but alcohol keeps you in light sleep and prevents you from reaching deep sleep. Spicy foods may cause stomach discomfort in some people, which can interfere with sleep.

　　Additionally, avoid gas-producing foods at dinner, such as bean products, which can cause bloating and discomfort, also hindering sleep. As the saying goes, “Radish before bed, ginger upon waking.” Choosing a balanced dinner combination is important. Aim for easily digestible, light foods at dinner, and don’t eat too late.

　　For healthy adults, regular exercise is essential. Endurance exercises such as walking, swimming, or cycling—3 to 5 times per week for 30 to 60 minutes each—are common prescriptions to improve sleep quality. For seniors, swimming, walking, and cycling are great ways to stay flexible and enhance oxygen consumption. Start exercising gradually—doing some stretching or swimming daily is fine, but avoid overexertion.

　　Generally, it’s also good to engage in moderate exercise after dinner, such as taking a walk. On one hand, it aids digestion, and on the other, it relaxes both body and mind, preparing you for a good night’s sleep.
