Before buying a new mattress, you may want to test different firmness levels when possible.
Remember that mattress quality is only one factor. Persistent pain may have causes unrelated to your bed, and changing mattresses alone may not resolve it.
11. Why You May Still Feel Tired After Eight Hours of Sleep
Your sleeping position is only one part of healthy
sleep.
You may sleep for eight hours and still feel exhausted if your sleep is frequently interrupted or if you have an untreated sleep disorder.
Other factors include:
An irregular sleep schedule.
Excessive caffeine late in the day.
Alcohol close to bedtime.
Stress and anxiety.
Pain or uncomfortable room temperatures.
Certain medications.
Obstructive sleep apnea or other sleep disorders.
For most adults, regularly obtaining at least seven hours of sleep is a useful general target, although individual needs vary.
Try maintaining a consistent bedtime and wake-up time, keeping the bedroom
dark and quiet, and allowing enough time for uninterrupted rest.
