The Major Heat (大暑) period is one of the hottest times of the year in the traditional Chinese solar terms, typically occurring in late July. Yesterday is the Major Heat Day of 2024. During this period, the body undergoes various physiological changes due to the extreme heat and humidity. Understanding these changes and taking appropriate measures can help maintain good health.
Characteristics of Blood Pressure and Blood Oxygen Levels
During the Major Heat period, the body's blood pressure and blood oxygen levels can be affected by the high temperatures:
Blood Pressure: The heat can cause blood vessels to dilate, leading to lower blood pressure for some individuals. However, the body's efforts to cool itself through increased sweating can lead to dehydration, which may cause blood pressure to rise. Therefore, fluctuations in blood pressure are common during this period.
Blood Oxygen Levels: High temperatures can strain the cardiovascular and respiratory systems. The body may struggle to maintain optimal oxygen levels, especially in individuals with pre-existing conditions like chronic obstructive pulmonary disease (COPD) or heart disease.
Recommended Monitoring Frequency
To ensure health and safety during the Major Heat period, it is important to monitor blood pressure and blood oxygen levels regularly:
Blood Pressure: Individuals, especially those with hypertension, should monitor their blood pressure at least twice a day—once in the morning and once in the evening. This helps in identifying any unusual fluctuations and taking timely action.
Blood Oxygen Levels: For those with respiratory issues or at high risk, checking blood oxygen levels daily using a pulse oximeter can provide early warnings of potential problems. For others, monitoring a few times a week might be sufficient.
In high temperatures, people may be reluctant to visit hospitals or clinics to monitor their blood pressure and blood oxygen levels. Instead, it is convenient to have home devices such as a blood pressure monitor and a portable pulse oximeter. Joytech home use blood pressure monitors and pulse oximeters are CE MDR approval.
Home electronic blood pressure monitors can professionally and scientifically complete daily monitoring, from blood pressure classification to abnormal blood pressure warnings, and multiple measurements to ensure accuracy. Portable fingertip pulse oximeters do not require professional knowledge; they simply clip onto a finger and are ready to use. They also provide beeps and tips for abnormal readings, making them very helpful for daily home monitoring.
Dietary Considerations
Maintaining a healthy diet is crucial during the Major Heat period. The following dietary tips can help manage blood pressure and overall well-being:
Hydration: Drink plenty of water to stay hydrated. Dehydration can lead to increased blood pressure and other health issues.
Fruits and Vegetables: Incorporate a variety of fruits and vegetables into your diet. These foods are rich in essential vitamins, minerals, and antioxidants that support overall health.
Limit Salt Intake: High salt intake can raise blood pressure. Use herbs and spices to flavor your food instead of salt.
Avoid Processed Foods: Processed foods often contain high levels of sodium and unhealthy fats. Opt for fresh, whole foods instead.
Fruits That Help Lower Blood Pressure
Several fruits are particularly beneficial for lowering blood pressure and providing relief from the heat:
Watermelon: Rich in water content and lycopene, watermelon helps keep the body hydrated and may aid in reducing blood pressure.
Cantaloupe: Another hydrating fruit, cantaloupe is high in potassium, which helps balance sodium levels and manage blood pressure.
Berries: Blueberries, strawberries, and raspberries are packed with antioxidants and have been shown to help lower blood pressure.
Kiwi: Kiwis are rich in vitamin C and potassium, both of which contribute to heart health and blood pressure regulation.
Bananas: High in potassium, bananas can help counteract the effects of sodium in the body and support healthy blood pressure levels.
Conclusion
During the Major Heat period, paying attention to changes in blood pressure and blood oxygen levels is essential. Regular monitoring, a balanced diet, and the inclusion of specific fruits can help manage these changes and maintain good health. Staying hydrated and avoiding excessive salt and processed foods are key strategies to navigate this hot and humid time of the year safely.
