Blood pressure, cholesterol levels, adrenaline, cortisol, and glucose levels can all be affected by stress and depression, which are the result of not submitting to Allah. The physical effects of these mental illnesses include mental illness, drug addiction, insomnia, skin, stomach, and blood pressure disorders, colds, migraines, bone diseases, kidney imbalances, respiratory difficulties, allergies, heart attacks, and brain swelling. To avoid these, believers must live by the moral values of the Qur'an, trust in Allah, look for the good in all things, and accept what happens with the hope of His promise.
