Here's why:
* Body temperature varies: Your overall body temperature can change throughout the day due to factors like activity level, time of day, and even the environment you're in.
* Tongue location: The tongue is a muscle, and muscles generate heat. However, it's also a moist, exposed tissue.
* External factors: Eating hot or cold food, drinking beverages, and even breathing through your mouth can all affect the temperature of your tongue.
Instead of focusing on a specific "regular" temperature, it's more important to consider these factors:
* If your tongue feels unusually hot or cold, it could be a sign of a health issue. If you're concerned, consult with a doctor.
* Using a thermometer to take your temperature is generally a more reliable way to assess your overall health.
