The American Health Association actually looked at different kinds of meditation techniques ranging from focussed attention to Transcendental meditation (TM), and contemplative forms like Zen and mindfulness techniques. Out of these, TM was found to have a modest effect on blood pressure reduction, but whether it is superior to other techniques is hard to say since head-to-head trials have not taken place.
3. Quit smoking and alcohol: Because, neither of the two is of any benefit to your health. What's more is that smoking is listed as a causative factor for almost all diseases. You name a disease, and smoking will be a contributing factor to it. Alcohol, on the other hand, has direct links with increasing blood pressure. No amount of alcohol intake is safe or healthy for men or women.
Sleep. Short and poor-quality sleep are both associated with raised blood pressure (40). On the other side of the spectrum, excessively long sleep may also be harmful. One study found increased blood pressure in those who got fewer than five hours of sleep per night and in those who averaged more than nine hours of sleep per night, when compared with people who slept around seven hours (41). I suspect that it’s not the long sleep itself that is the problem, but that some underlying condition is both increasing sleep requirement and raising blood pressure.
