Revealing Health Risks You Shouldn’t Ignore"},"content":{"rendered":"

During hot seasons with continuously rising temperatures, many people may begin to experience fatigue, rapid heartbeat, or dizziness, especially the elderly and those with hypertension, who may worry about how the hot weather affects their blood pressure.<\/span><\/p>\n

In reality, hot weather can both increase and decrease blood pressure levels, depending on each person’s physical condition. Generally, when the weather gets hotter, the body dilates blood vessels to help release heat, which may lower blood pressure. However, if the body becomes dehydrated or loses minerals from excessive sweating, the heart may have to work harder, resulting in increased blood pressure. Therefore, those with hypertension and the elderly should maintain their body’s water balance and monitor any symptoms that may occur.<\/span><\/p>\n

Checking High Blood Pressure in Hot Weather<\/b><\/h2>\n

Using a blood pressure monitor is the easiest and most convenient method. Normal blood pressure is around 120\/80 mmHg. If measurements reach 140\/90 mmHg or higher, there’s a risk of hypertension. This disease often has asymptomatic symptoms, even when blood pressure reaches dangerous levels. However, in some cases, patients may experience dizziness, neck tension, heart palpitations, or fatigue, especially in the morning after waking up.<\/span><\/p>\n
