Always tired? 6 reasons your energy is low

Feeling tired after a busy week is normal. Feeling exhausted most days — even after a full night’s sleep — is your body telling you something. The good news: many of the most common causes are easy to check and very treatable.

1. You’re not getting restful sleep

Hours in bed don’t always equal quality sleep. Stress, screens, night sweats, snoring or sleep apnea can all keep you from reaching deep, restorative sleep.

2. Low iron or anemia

Iron helps carry oxygen through your body. Heavy periods, pregnancy, and some diets can lower iron stores, leading to fatigue, shortness of breath and even hair shedding. A simple blood test can check your iron and ferritin.

3. Your thyroid is out of balance

An underactive thyroid can cause tiredness, feeling cold, weight gain, dry skin and low mood. Thyroid problems are common — especially in women — and are diagnosed with blood work.

4. Hormone changes

Perimenopause and menopause can disrupt sleep and energy for women. In men, low testosterone can cause fatigue, low motivation and reduced drive. Hormone labs and a careful look at your symptoms can help sort out what’s going on.

5. Blood sugar swings

Skipping meals, eating mostly refined carbs, or insulin resistance can cause energy crashes during the day. Balanced meals with protein and fiber help keep energy steadier.

6. Stress, mood and burnout

Ongoing stress, anxiety and depression can show up as physical exhaustion. These are real, common health issues — and they deserve care too.
