Drinking a cup of honey before going to bed at night can relieve tension and promote sleep. For patients with cardiovascular diseases, oral honey is helpful to dilate coronary arteries, increase the blood supply capacity of the heart and regulate blood pressure. However, it should be noted that if you have diabetes, you can't drink honey, because drinking honey will affect your blood sugar level and make it difficult to control your blood sugar. Honey can't be given to babies because it contains certain hormones.
