What we measure by touching something is not an absolute temperature but merely a difference in temperatures and the difference is not noticeable when both hand and head belong to the same, high temperature person.

Touching your own forehead may not accurately determine if you have a high temperature because your body quickly adapts to its own temperature. It is better to use a thermometer to get a more accurate reading.

the touch your forehead to tell fever comes from the premice you don't have fever yourself. If someone's temperature is higher than yours you can conclude he might have a fever but if you touch your own forehead, the temperature would be the same as your hand so you might not be able to tell difference between the two.

When you touch someone else's forehead t test for temperature, what you're really doing is testing for the difference in temperature between your hand and their forehead. When you touch your own forehead, there's very little difference regardless of your temp.

Mostly because your hand temperature is affected by the fever, so your forehead wouldn't feel hot.

Your're hand is most likely the same temperature as your head, as one without a fever will feel you as much warmer than their own hand. Sorry if this answer isn't totally correct.

Why cant you establish wheter you are running a high temperature by touching your own forehead?

Touching your own forehead may not be an accurate way to determine if you have a high temperature because your body temperature can vary throughout the day and may not always be reflected in the temperature of your skin. For a more accurate reading, it is recommended to use a thermometer to measure your body temperature.


Why cannot you establish whether you are running a high temperature by touching your own fore head?

Feeling the temperature of your own forehead may not accurately reflect whether you have a fever because your body gets used to its own temperature over time. The best way to check for a fever is by using a thermometer for an accurate reading.
