2. Dizziness and weakness – Feeling lightheaded or experiencing muscle fatigue suggests inadequate oxygen supply to the brain and muscles.
3. Rapid heartbeat (Tachycardia) – A resting heart rate over 100 BPM or irregular beats may signal the heart is overcompensating for low oxygen.
4. Muscle pain and cramps – Oxygen deficiency can lead to cramps or chest pain (angina), which may improve with electrolyte and vitamin intake.
5. Heavy legs – Difficulty climbing stairs or walking uphill could result from poor oxygen circulation, often linked to vitamin C and E deficiencies.
6. Brittle nails – Pale, fragile nails with deep ridges may indicate anemia and inadequate oxygen transport.
7. Bluish skin (Cyanosis) – A bluish tint to the skin or lips suggests severe oxygen depletion and requires immediate medical attention.
8. Confusion and mental fatigue –
Poor oxygen supply to the brain can cause mental fog, irritability, or sluggishness, often worsened by excess sugar intake or vitamin B1 deficiency.
