<unk>  requires no therapy as long as the individual does not suffer from the symptoms or pathological sequelae occur. The treatment is based on three pillars: lifestyle interventions, diet, and medication. A healthy lifestyle should include regular sleep, weight stabilization (in the sense of not being underweight), avoiding periods of fasting, and avoidance of known trigger factors such as cold. Regular physical exercise is beneficial, while extreme sports might be detrimental. Nutrition should contain many antioxidants, such as those found in green tea, black filter coffee, red wine, blueberries, and fruits. Omega-3 fatty acids, especially in the form of fish, improve the regulation of blood flow. If blood pressure is very low, salt intake should be increased. Drugs that can lead to vasoconstriction should be avoided. If blood pressure is too low, sleeping pills should be taken cautiously. Magnesium and calcium antagonists may help against the vascular dysregulation. With lifestyle interventions, attacks—particularly pronounced symptoms such as massive cold extremities, tinnitus, or migraine-like episodes—can be avoided or reduced. Stabilizing weight (i.e. not being underweight) and the avoidance of periods of fasting are important. Medical treatment is necessary when normal tension glaucoma is present. In these cases, in addition to the ophthalmologic treatment of glaucoma, the patient's usually low blood pressure should be addressed. With dietary measures such as salt intake and sometimes with low-dose steroids, a drop in blood pressure, especially during sleep, can often be prevented. These nightly "dips" of blood pressure in normal tension glaucoma patients with<unk>  can significantly damage the sensory cells of the retina.
