Hi thanks for your question.
The best way to avoid spikes is to decrease your salt intake and sstay cooled.
You have to avoid stress
and tension at all cost,that is the only way to avoid spikes in blood pressure.
This will work ggod for primaey hypertension,which doesn't have any established cause and not for secondary hypertension
in which there is some underlying etiology ,which one has to correct to avoid spikes in blood pressure.
Hope this answers your question.
