Soaking in hot springs during winter is undoubtedly a delightful leisure activity. However, many individuals with cardiovascular diseases or hypertension harbor concerns: Can those with high blood pressure enjoy hot springs? What precautions should they take?
Moderate hot spring soaking can improve cerebral cortex and cardiovascular function while dilating skin capillaries.Data indicates that over 95% of stage I hypertension patients and approximately 70% of stage II hypertension patients experience reduced blood pressure after appropriate hot spring bathing. Individuals with hypertension or heart disease may bathe in hot springs while adhering to regular medication regimens, but compared to healthy individuals, they must follow specific precautions, including:
Time control. Initial bathing sessions should not exceed 10 minutes, gradually increasing duration after acclimatization.Limit each session to no more than 20 minutes. Alternating between soaking and resting is advisable to ensure adequate cardiac blood supply and prevent chest tightness or pain. For example, within a total 20-minute session, each immersion could last 5 minutes. Control water temperature. Excessively high temperatures increase cardiac strain, potentially causing palpitations or shortness of breath. Water between 38°C and 40°C (100°F to 104°F) is optimal.Before entering the hot spring pool, dip your feet first. Soak your feet initially, then continuously splash water over your entire body with both hands. Only fully immerse yourself after acclimating to the water temperature. Do not submerge beyond chest level. Keep the water surface below your chest. Avoid massage. Do not massage yourself while soaking in the hot spring. This is because your body's blood circulation accelerates and heart rate increases during soaking. Simultaneous massage would place additional strain on the heart.
Exit slowly. Since hot spring bathing primarily submerges the lower body, blood vessels in those areas dilate. Changing position abruptly (from sitting to standing) can cause insufficient blood supply to the brain, especially in the elderly. Mild cases may result in dizziness or headaches, while severe cases may lead to falls. Therefore, rise cautiously and slowly.
Carry medication with you. Hot spring bathing causes significant fluid loss. Drink water periodically to replenish fluids and prevent dehydration. Individuals with cardiovascular conditions should bring emergency medication and carry their regular prescriptions. It's best to have a family member accompany you in case of unexpected incidents.
Hypertension patients must also take precautions: avoid bathing on an empty stomach or immediately after meals. Alcohol consumption before bathing is strictly prohibited, and hypertensive individuals should generally avoid alcohol. Those with severe hypertension complicated by conditions like cerebral hemorrhage, heart failure, or uremia must absolutely refrain from hot spring bathing. This is crucial to remember.
