Normal skin temperature at night for healthy adults typically ranges between 33 and 37°C (92.3 and 98.4°F) when measured at the wrist.
While core body temperature remains relatively stable around 37 degrees Celsius (98.6°F), skin temperature exhibits minor fluctuations. These fluctuations can vary by up to one degree Celsius (1.8°F) from night to night, influenced by factors such as:
- Ambient temperature: The temperature of the surrounding environment plays a significant role.
- Activity level: Prior physical activity can affect skin temperature.
- Clothing and bedding: Insulation from clothing and bedding can influence skin temperature.
- Circadian rhythm: The body's natural sleep-wake cycle affects temperature regulation.
Therefore, it's important to consider these factors when interpreting skin temperature measurements. A single reading outside the specified range isn't necessarily cause for concern unless accompanied by other symptoms.
