Getting Enough Sleep But Still Tired?

Other Causes

Psychological Causes

Stress, major life events like divorce, job change/loss, or relationship troubles can drain you both mentally and physically. If you don’t feel right for more than two weeks, seek professional help.

Underlying Medical Conditions

Thyroid problems, diabetes and heart disease are just a few conditions that could be making you tired. Get a physical so your doctor can rule out these things.

Poor Eating Habits

Eating near bedtime and using caffeine and alcohol can significantly worsen sleep quality. Make sure to eat at least two to three hours before preparing to sleep.

Sleep Apnea

Pauses in breathing while asleep can affect your overall sleep quality. Many people with sleep apnea don’t even know they have it.

Medication Side Effects

Some medications can cause drowsiness. Check with your pharmacist or doctor.
