8. You’re experiencing way too many headaches
It is normal to have headaches every now and then, especially when you’re dealing with a hectic lifestyle. Stress and sleep deprivation are the most common causes of headaches, so a good night’s sleep should put you back on track, however, if nothing seems to work, it may be time to check your iron levels.
“To compensate for decreased red cells, there’s increased total blood flow to the brain and that can cause some pain,” Dr. Kahn explains. The headaches can actually range from low-grade to migraines, too, so do not ignore it even if you’re only feeling mild pain in the first place.
