Why You Might Feel Warmer Than Usual
BBT rise after ovulation, progesterone and body temperature
The Progesterone-Temperature Connection
If you feel warmer after ovulation — needing to kick off covers at night or running a bit hotter — you can thank progesterone. It raises your basal body temperature by about 0.2-0.5 degrees Fahrenheit.
Before ovulation, BBT typically ranges from 96.0-97.5 degrees Fahrenheit. After ovulation, it shifts up to roughly 97.0-98.0 degrees Fahrenheit and stays elevated until your period starts.
This temperature shift creates a warmer environment in the uterus — optimal for potential embryo implantation.
BBT Tracking for Cycle Awareness
Tracking basal body temperature is one of the oldest methods of confirming ovulation. The sustained temperature rise proves progesterone is being produced, which means ovulation has occurred.
To track BBT accurately, take your temperature at the same time every morning, before getting out of bed, talking, or drinking water. Use a basal body thermometer and log the reading in Naya.
BBT confirms ovulation after it has happened — it doesn't predict it in advance. For predicting ovulation, combine BBT with cervical mucus tracking and/or OPKs.
Managing the Warmth
Keep your bedroom cool — lower the thermostat by a degree or two, or use a fan. Breathable, moisture-wicking fabrics for pajamas and bedding can help prevent overheating at night.
Stay hydrated — when your core temperature is elevated, you may lose slightly more water through perspiration and breathing.
If your temperature stays elevated for 18 or more consecutive days (and your period hasn't arrived), this could be an early sign of pregnancy.

Quick Tip
Keep your bedroom one degree cooler during the luteal phase to counteract the progesterone-related temperature rise and improve sleep.
