The formula to calculate the ideal pillow height is:
\[ \text{PH} = \text{SW} - \text{MH} \]
Where:
Pillow height refers to the thickness or elevation of a pillow that provides the best support for the neck and head during sleep. The ideal pillow height helps maintain a neutral alignment of the spine, preventing neck pain and discomfort. It is influenced by the individual's shoulder width and the height of the mattress.
Let's assume the following values:
Using the formula:
\[ \text{PH} = 18 - 10 = 8 \]
The Ideal Pillow Height is 8 inches.
Let's assume the following values:
Using the formula:
\[ \text{PH} = 12 - 14 = -2 \rightarrow 0 \]
The Ideal Pillow Height is 0 inches.
