Your mother’s situation does sound worrisome, as you are describing falls and also some concerns with thinking. Her age of 96 is pretty old, so clinical research studies don’t provide much guidance on what is optimal blood pressure. Unless she has compelling medical reasons to aim for a SBP of 120, most geriatricians would probably reduce her BP meds and try to aim for a SBP in the 130s or 140s. So you may want to ask your mother’s doctor to discuss with you what is a suitable BP goal for her, and whether a reduction in BP meds might be reasonable.
Yoga is an ancient practice of life science and a way of living that was originated thousands of years ago in India. A great way of reducing high blood pressure, yoga is really effective in treating issues naturally. So practice asanas like Sukhasana, Uttanasana, Adho Mukha Svanasana, Vriasana, Baddha Konasana, Supta Padanugusthasana, Setu Bandhanasna, and Shavasana, for lowering down the blood pressure.
Kiwis are another fruit that positively impacts blood pressure. Some researchers studied how the fruit fares compared to apples. They found that eating three kiwis a day over eight weeks reduced blood pressure in people with slightly high blood pressure more so than eating one apple per day during the same time. A daily serving of kiwi was also found to reduce blood pressure in people with only mildly elevated levels. Kiwis are also an excellent source of vitamin C which can also also improve blood pressure.
