Numerous illnesses, including gastrointestinal issues, muscle tightness, and an elevated risk of heart attack, are mostly brought on by stress. Regretfully, migraines can also be brought on by stress. Stress can be attributed to having an overly busy schedule, an endless to-do list, or frequent meetings. However, physical strain, such as fatigue following an exceptionally hard workout, might also put you in the migraine zone.
