Your blood pressure is well within normal limits, in fact would be considered very healthy. 120 over 80 is just a guide line and flucuations do occur.

Everyone has a different blood pressure and it can change in the same person during the day and night. Your blood pressure varies by large amounts, depending on what you are doing. The lowest blood pressures occur when you are asleep or if you relax all your muscles. Standing up, exercising or anxiety all cause an increase in blood pressure. This is why when you have your blood pressure level assessed it is so important to have it measured under the same conditions every time.

Don worry!

Its just normal.

Try taking good food and sleep in regular hours!

If this problem is worrying u, try drinking salted water with lots of fruit juices! Or u can use ELCTRAL powder comercially available in market.

I suggest.. just ignore it now. Don worry!
