Never had 'high blood pressure'. The most successful actions I have found to stay lean, feel energetic and sleep soundly for 8 hours is regular daily exercise: walking every day toward a couple of miles, stretching, some light yoga and just the basic Vitamin supplements; A,D,E,C,Zinc,B12. A plus if you can make protein drinks; yogurt, frozen berries or best fresh, protein powder, cut fruit, any other powder supplements that indicate to you. No drugs or prescription meds. No smoking. No alcohol. No fried foods. Grass fed beef. Organic shopping as much as realistic. Regular sexual activity. Also awareness of dehydration in the Thai Sun and take daily electrolyte drink from three store bought ingredients that all the electrolyte products are made from; Salt, Potassium Chloride and Magnesium Glycinate. It's a fallacy that HBP is due to too much salt. There has never been a verifiable research on it that shows salt is harmful. In fact there are studies that show the longest living groups of humans consume much more salt daily than the average American. Good luck.
