I’ve never had it before (hbp)
I was sick recently so I am just starting to get my apetite back. I eat a pretty balanced diet. I drink lots of water.
Can it be caused by stress or lack of rest?
yes. it can be caused my stress or lack of rest.. your heart will need to produce more blood to cater the need of your active body..

High blood pressure can be caused by many things, but I would keep a really close check on it. Sometimes it is just due to your heart having to pump for two now instead of one.
