3. Physical discomfort and health factors

The body may also wake up in response to mild physical discomfort that isn’t obvious during the day.
Common contributors include:
- Arthritis or joint pain
- Back discomfort
- Acid reflux at night
- Dry mouth
- Muscle cramps
- Temperature fluctuations
Needing to use the bathroom is especially common. As the bladder becomes more sensitive with age, nighttime trips may increase.
Certain medications can also influence sleep by causing:
- More frequent urination
- Changes in body temperature
- Lighter, less restorative sleep
- Many people don’t realize the connection until they discuss it with a healthcare provider.
