On a cold winter morning, Mr. Zhang, a retired teacher, prepares to take a walk in the park as usual. Despite the sudden drop in temperature, he wore only a light coat and decided that the brief cold was not enough to disturb his daily routine. However, when he returned home, he suddenly felt a sharp pain in his chest and it became difficult to breathe. His family rushed him to the hospital, where doctors diagnosed him with an acute heart problem caused by a cold heart that required immediate surgery. 
This story is not unique. Every winter, many middle-aged and elderly people like Mr. Zhang suffer from "cold hearts" because they neglect to keep warm, and have to face a sudden health crisis. This not only brings huge psychological and economic pressure to individuals and families, but also serves as a warning: protecting the heart from "frozen heart" in winter is an important topic that we cannot ignore. 1.Warmth Protection: Protects the Heart from the ColdIn winter, the cold climate poses a threat to the heart health of middle-aged and elderly people. Keeping your body warm is the first step you can take to prevent your heart from getting cold. It is advisable to focus on keeping the chest area warm and wearing appropriate thermal underwear and coats, especially when going out. Choose a material that is breathable and warm, such as wool or down, to avoid the cold sensation of sweat. In addition, the indoor temperature is maintained within a comfortable range to avoid the burden on the heart due to the large temperature difference between indoor and outdoor. 2.Heart-Friendly Diet: Balanced nutrition, heart-friendly Proper eating habits are essential for heart health. Middle-aged and elderly people should reduce their intake of high-salt, high-fat foods and increase foods rich in omega-3 fatty acids, such as deep-sea fish, as well as fresh fruits and vegetables rich in antioxidants. These foods help reduce the risk of cardiovascular disease and promote blood circulation. Regular intake of nuts and whole grains can also provide the essential nutrients your heart needs to maintain heart health. 3.Moderate exercise: Activates the body and warms the heartRegular moderate physical activity can enhance heart function and improve the body's ability to adapt to cold. It is recommended that middle-aged and elderly people choose low-intensity, gentle exercises such as walking and tai chi, which should last at least 30 minutes a day. In cold weather, indoor exercise is a safe option to stay physically active by doing chores, going up and down stairs, and more. Do a proper warm-up and relaxation before and after exercise to avoid overloading the heart. 4.Avoid drastic temperature differences: Smooth transition, protect the heartWhen the temperature difference between indoor and outdoor is large in winter, the adaptability of the heart of middle-aged and elderly people is weak, which is easy to cause heart burden. It is advisable to adjust clothing appropriately, such as taking off or putting on a jacket, before entering or exiting a cold or warm environment, and avoid direct exposure to severe temperature differences. In addition, avoid going out for long periods of time in extremely cold weather to reduce the stress on your heart due to sudden temperature changes. 5.Regular check-ups: Early detection and prevention of heart health are essential for early detection of potential heart problems. It is recommended that middle-aged and older adults have at least one annual heart health check-up, including an electrocardiogram, blood pressure monitoring, and tests for lipid and blood glucose levels. With regular check-ups, heart health problems can be detected and treated in a timely manner, preventing the condition from deteriorating to the point where emergency surgery is required. 
In winter, cold weather puts more pressure on the heart, especially for middle-aged and elderly people, it is important to stay alert and know how to take the right action in the event of an emergency after experiencing a cold heart. The following two life-saving measures can not only save lives at critical moments, but also reduce the severity of the disease to a large extent. 1.Recognize and seek help in time: The first line of defense is to be able to recognize the signs and seek help in time when there is a problem with the cold heart, which is the first step to saving lives. Typical symptoms include, but are not limited to, chest pain, difficulty breathing, rapid or irregular heartbeat, paleness, and cold sweats. These symptoms may indicate that the heart is experiencing extreme stress or a heart attack. The key is not to ignore these warning signs, call emergency services** immediately, and describe symptoms in as much detail as possible, which can help first responders respond more quickly and take appropriate action. 
2.Mastering Basic CPR Skills: The Key to Emergency RescueAt the critical moment of waiting for professional medical help to arrive, understanding and being able to perform basic CPR techniques can mean the difference between life and death. CPR is an emergency rescue technique designed to maintain the function of vital organs by restoring blood circulation and breathing to the heart until further medical assistance arrives. The basic steps to perform CPR include safely lying the patient on their back, chest compressions, and rescue breaths. Chest compressions should be placed on the sternum** at a depth of at least 5 cm of the ribcage at a rate of 100 to 120 compressions per minute. If you don't know how to give rescue breaths, continuous chest compressions can help.
