Low oxygen affects energy production at the cellular level.

This can cause:

• Unusual tiredness even after rest
• Weak muscles
• Feeling “drained” without reason
• Difficulty doing normal daily tasks

🧠 This is not normal tiredness — it is oxygen-related fatigue.

🤕 6. Headaches or Pressure in the Head

Reduced oxygen to the brain can cause:

• Persistent headaches
• Dull or throbbing pain
• Feeling of pressure in the head
• Worsening symptoms during physical activity

This symptom is often overlooked but important.

🧍‍♂️ 7. Dizziness or Lightheadedness

Low oxygen can affect balance and blood flow.

You may feel:

• Dizzy when standing up
• Lightheaded or faint
• Unsteady walking
• Near-fainting episodes

⚠️ This increases the risk of falls and injury.

😟 8. Anxiety, Restlessness, or “Air Hunger”

Some people experience a strong feeling that they cannot get enough air.

This may include:

• Sudden anxiety without clear cause
• Restlessness or panic feeling
• Constant urge to take deep breaths
• Feeling “air hungry”

🧠 This is the brain reacting to oxygen shortage.
