Take good health protection measures during long voyages to better adapt to offshore environments
2024-04-28
During long voyages, naval officers and soldiers are more susceptible to diseases such as insomnia, seasickness, and sunburn due to environmental factors. Understanding the causes and development process of these diseases can help officers and soldiers accurately assess their own situation and take timely prevention and treatment measures. Experts from the First Affiliated Hospital of Naval Medical University have compiled some health protection knowledge during long voyages, hoping to help naval officers and soldiers better adapt to offshore environments. During a long voyage, officers and soldiers are prone to insomnia due to the combined effects of various factors such as wind, waves, noise, and pressure. Insomnia is a subjective experience that affects daytime social function due to difficulties in falling asleep and maintaining sleep, resulting in insufficient sleep quality or duration to meet normal physiological needs. If it takes more than 30 minutes to fall asleep, more than 30 minutes to fall asleep again after waking up, and 30 minutes earlier than usual to wake up, and these symptoms appear more than half of the time each week, affecting normal work and life the next day, it can be judged as insomnia. Long term insomnia can damage physical and mental health, not only leading to weakened immunity and memory, but also possible psychological problems such as nervousness, irritability, anxiety, and depression. If insomnia occurs during a long flight, the following methods can be used to regulate it. Refuse "sleep anxiety". When some comrades experience poor sleep, they become very anxious, which can actually lead to insomnia. In fact, poor sleep for a short period of time will not have a significant impact on the body. If you occasionally experience poor sleep, you can improve your sleep by meditating before bed, listening to light music, and other methods. Create a suitable sleeping environment. Officers and soldiers can choose appropriate ventilation and lighting conditions before bedtime, adjust their rest posture and pillow height. Comrades with sleep disorders can try wearing noise cancelling headphones, blackout eye masks, etc. to help improve their sleep quality. Try to keep the brain in a calm state before going to bed and avoid distractions from sleep. Maintain good exercise habits. Exercise helps alleviate difficulty falling asleep and deepen sleep. It should be noted that do not engage in vigorous exercise within 2 hours before bedtime. Vigorous exercise before bedtime can increase body temperature, leading to delayed sleep onset and frequent waking during sleep. Massage acupoints. Pressing and kneading acupoints such as Laogong and Anmian can help with sleep. Before going to bed, you can use your fingertips to massage the Laogong acupoint and the Anmian acupoint separately. Suggest kneading for about 1 minute each time. If there is still insomnia after applying the above methods, medication that promotes sleep can be taken appropriately under the guidance of a doctor. Second seasickness is one of the symptoms that officers and soldiers are more likely to experience during long voyages. During navigation, ships may experience sudden increases in swaying amplitude due to wind and waves, which can easily lead to seasickness. The main symptoms include dizziness, nausea, decreased appetite, and in severe cases, vomiting, palpitations, chest tightness, excessive sweating, and cold limbs. In addition, the narrow and enclosed environment of the ship, as well as poor air circulation, can also easily trigger seasickness reactions. Seasickness is a symptom of balance imbalance. The balance of the human body is mainly maintained by the vestibule, visual and proprioceptive systems under the command of the brain. During the navigation of the ship, the vestibular receptors in the ears sense the information of ups and downs, back and forth shaking, and left and right shaking, and send a signal to the brain that the human body is moving.
