Uncover causes of constant fatigue

Discover the causes of constant fatigue and find effective solutions.

Constantly Tired?

If you are constantly tired – even despite plenty of sleep – there is often more behind it than "not enough sleep." Often, there are a few easily verifiable factors: sleep quality, hydration/nutrition, stress – and not infrequently a nutrient deficiency.

Measure vitamins and nutrients

Sleep

  • Blue light in the evening (phone/tablet) can disrupt falling asleep and the depth of sleep.
  • Restless nights due to noise, alcohol, or late eating cost deep sleep.
  • Note Sleep Apnea: loud snoring, breathing pauses, morning headaches – seek medical advice.

What helps quickly against fatigue? 60 minutes screen-free in the evening, keep the bedroom cool (approx. 18 °C), and test fixed sleep times.

Liquid & Food

  • Drinking too little quickly leads to fatigue – especially in the office or during sports.
  • Blood sugar rollercoaster (lots of sweets/white flour) often leads to an afternoon slump.
  • Too much coffee only masks it briefly and later intensifies the energy dip.

Practical: Keep water visibly available, include protein + fiber with every meal, and have sweets after meals rather than on an empty stomach.

Fatigue due to nutrient deficiency

If you are wondering "Why am I constantly tired?", it is worth looking at storage values – especially with little sun, stress, vegetarian/vegan diet, intense sports, or frequent infections.

  • Iron/Ferritin: relevant for oxygen transport – deficiency can promote extreme fatigue.
  • Vitamin D: often low in autumn/winter.
  • Vitamin B12 (and transport markers): important for nerves & energy metabolism.
  • Magnesium, zinc, selenium and others: play a role in performance and regeneration.
Our tip:

Thyroid, Hormones, Stress

A thyroid underactivity or a permanently elevated stress level can cause fatigue – typical symptoms include lack of drive, feeling cold, weight gain, or sleep problems. If suspected: have it medically checked (TSH, fT3/fT4 as needed).

Psyche & Overload

If fatigue is accompanied by loss of interest, inner emptiness, or constant tension, mental exhaustion may also play a role. Seek support if the feeling persists or intensifies.

What to do against constant fatigue: Quick guide

  1. 7 Day Basics: Sleep routine, more water, less sugar.
  2. Create Clarity: In case of persistent exhaustion, specifically check nutrient status (e.g., with the Nutrient Analysis Plus).
  3. Consult a doctor: if there are severe symptoms, new symptoms, or suspicion of sleep apnea/thyroid issues.
