Intermittent fasting (IF) is an eating pattern that cycles between periods of fasting and eating. It doesn't specify which foods you should eat, but rather when you should eat them.  There are many different types of IF, but the most common is probably the 16/8 method, where you fast for 16 hours and then eat during an 8-hour window. Other popular methods include the 5:2 diet (fasting for two days per week and eating normally for the other five), as well as more extreme versions like the warrior diet (eating only one large meal per day). IF has become popular in recent years because it's a simple way to lose weight without having to count calories.

There are a lot of different ways to do intermittent fasting, but the basic idea is that you go without food for a set period of time, and then eat all your meals in a shorter window. For example, you might fast for 16 hours and then eat all your meals during an 8-hour window.

Some people do this every day, while others do it on alternate days.

Why Always Tired Even After Proper Sleep

Why Always Tired Even After Proper Sleep

Feeling tired after a long workday is normal. But if you still feel exhausted even after a full night’s sleep, it could mean that something else is affecting your energy levels. Many people experience this and often overlook the actual cause. Understanding why always tired even after proper sleep can help you take practical steps to regain energy and improve your daily life.

1. Poor Sleep Quality

You may be in bed for 7–8 hours, but that doesn’t mean your body gets proper rest. Sleep quality is just as important as the number of hours. Disturbed sleep, frequent waking, or light sleep can prevent your body from entering deep sleep stages, which are necessary for repair and recovery.

Fix it:

  • Maintain a fixed sleep routine
     

  • Avoid screens 1 hour before bed
     

  • Keep your bedroom quiet, dark, and cool
     

  • Limit caffeine after afternoon
     

2. Vitamin and Mineral Deficiencies

One of the most common hidden causes of constant fatigue is nutrient deficiency. Low Vitamin D and B12 levels or iron deficiency can cause tiredness, low concentration, and muscle weakness even if you get enough sleep.

Fix it:

  • Get a lab test for Vitamin D, B12 and Hemoglobin
     

  • Eat foods like leafy greens, eggs, fish, and whole grains
     

  • Take supplements if advised by a doctor
     

3. Thyroid Imbalance

An underactive thyroid (hypothyroidism) slows metabolism. This makes you feel tired all the time, even after proper rest. Thyroid disorders can also cause weight gain, dry skin, and low mood.

Fix it:

  • Get a Thyroid Function Test (T3, T4, TSH)
     

  • Follow up with medication and regular monitoring if needed
     

4. Poor Diet and Dehydration

Eating high sugar, fried, or processed foods can lead to spikes and drops in energy levels. Dehydration reduces circulation and affects oxygen supply to the brain and muscles, making you feel sluggish and tired.

Fix it:

  • Eat balanced meals with complex carbs, vegetables, and lean protein
     

  • Drink at least 2–2.5 liters of water daily
     

  • Avoid skipping meals
     

5. Stress and Mental Fatigue

High mental stress keeps your nervous system active at night, which interferes with deep sleep. Even if you fall asleep, your brain continues to stay active, which reduces the quality of rest.

Fix it:

  • Practice relaxation techniques such as deep breathing or short meditation
     

  • Reduce screen time, especially work-related tasks before bed
     

  • Set clear boundaries between work and personal time
     

6. Lack of Physical Activity

It might seem surprising, but lack of exercise can actually make you feel more tired. Regular physical activity improves circulation, oxygen delivery, and hormone regulation. All these support better sleep and higher daytime energy levels.

Fix it:

  • Aim for at least 30 minutes of walk or light exercise daily
     

  • Choose activities you enjoy to stay consistent
     

7. Hidden Medical Conditions

Certain medical conditions such as sleep apnea, anemia, diabetes, and heart disorders can also cause fatigue even when you sleep adequately. In such cases, early diagnosis is essential to prevent complications.

Fix it:

  • Schedule a health check-up if fatigue persists
     

  • Follow medical advice and treatment plans as directed
     

 

Conclusion

Waking up tired every day can affect your productivity, mood, and overall quality of life. If you want to boost your energy levels, look beyond just “getting enough sleep”. Pay attention to your diet, activity levels, stress, and underlying health issues. A simple set of tests and small lifestyle changes can make a big difference in your daily energy.

Take the first step today and find out why always tired even after proper sleep — and get back to feeling healthy and energetic again.
