FROM OUR EXPERTS
Summer is upon us, along with summer Migraines. Many of us have seen an increase in Migraines lately due to weather changes . There's nothing we can do to avoid changes in the weather, but we can avoid another common summer Migraine trigger — dehydration.
The human body is 65% water. Simply put, dehydration occurs as the result of excessive loss of water from the body — when we lose more water than we take in. It's a bit more complicated than that since the body loses valuable electrolytes as well. That's why sports drinks have become so popular; they replenish electrolytes as well as just fluid. Dehydration can be a major issue, both in and of itself and as a Migraine or headache trigger.

I realize your bigger concern tends to be how to LOWER high blood pressure , but today I want to touch on the reverse so you are aware of this potential problem.
Low blood pressure, also known as hypotension , is when your blood pressure drops below 90 mm Hg systolic (top number) or 60 mm Hg diastolic (bottom number).
If your blood pressure is normally on the low side, it’s not a concern as long as you are not experiencing symptoms associated with low blood pressure.
Lack of concentration
Rapid, shallow breathing
If you are experiencing these symptoms, you need to take action to correct and prevent blood pressure from dropping too low.
Dehydration and blood pressure
Dehydration can actually cause your blood pressure to be low …and not in a good way.
Dehydration is a lack of fluid in the body, often caused by inadequate fluid intake or excess fluid loss. ...
Even when healthy, drink plenty of fluid every day. Drink more when the weather is hot or you are exercising.
Carefully monitor someone who is ill, especially an infant, child, or older adult. If you believe that dehydration is developing, consult a doctor before the person becomes moderately or severely dehydrated. Begin fluid replacement as soon as vomiting and diarrhea start -- DO NOT wait for signs of dehydration.
Always encourage the person to drink during an illness, and remember that a person's fluid needs are greater when that person has fever, vomiting, or diarrhea. The easiest signs to monitor are urine output (there should be frequent wet diapers or trips to the bathroom), saliva in the mouth, and tears when crying.
