“Any time you have stress, there’s a crossover between the mind and hormones, which become triggers—in this case—for the neurotransmitter, adrenaline,” explains Susan Blum, M.D., MPH, and founder and director of the Blum Center for Health. Adrenaline just adds to the already existing stimulation and keeps your brain and body awake at night. In general, try to get enough sunlight and avoid using blue light-emitting electronics that stimulate the pineal gland. These can disturb melatonin production. “Taking magnesium, vitamin B6 and creating evening rituals all help to optimize sleep,” says Dr. Cabeca. Women over 40 may also consider an evening progesterone cream supplementation. Her mantra, however, is “Test, don’t guess,” so concerns should always be discussed with your physician.
