Here are some factors that can affect your body temperature:

• Time of day: Your body temperature is typically lowest in the early morning and highest in the evening.
• Activity level: Exercise raises your body temperature.
• Environment: Hot weather and humid environments can raise your body temperature.
• Illness: Infections can raise your body temperature.
• Certain medications: Some medications can raise or lower your body temperature.

If you are concerned about your body temperature, talk to your doctor. They can help you determine if your body temperature is normal and, if not, what may be causing it.
