My heart rate also rises and it hurts my throat. My sinuses feel numb and head gets constricted.
I found that much of the pain people experience is due to inflammatory response or dehydration.
Here's one option that I use much of the time and target to try to get family members to follow.
Body Weight (pounds) ÷ 60 = _______
Then add 1.
Example :. A 180 pound person
Divided by 60 = 3 quarts water
Add 1 and that person has a target goal of 4 quarts or one gallon.
This should be adjusted for activity level and temperature.
The easiest way to achieve this is to have a pitcher filled at the beginning of the day with the proper amount and replace other beverages with water.
I take a quality mineral supplement to offset the minerals that are washed out.
Starting the morning with a quart or more is a great way to start the day.
