Take heed of headaches. Headaches may be a symptom of hypertension.

High blood pressure can cause pounding headaches. The headache usually starts at the back
of
the head on getting up in the morning. A safe method of treatment for this is to immerse your
legs to calf-level in a tub of hot water for 15 to 20 minutes. This draws the blood away from the
head and down to the feet, relieving the headache.
Also helpful is the yogic practice known as pranayama. Stand erect with the feet aligned
straight and touching each other. Lock the fingers together with the hands beneath the chin
and keep them there through the entire exercise.
Slowly raise the arms as you inhale, filling your lungs with air. Feel the action of the breathing
through your throat. Then raise your arms above your head as you lean back and exhale, all
the while keeping the hands at your chin. When you completely exhale, feeling the movement
of the air through your throat, lower your arms and repeat the exercise 20 times.
