Natural remedies and herbs for improving sleep include chamomile, valerian root, and passionflower, which promote relaxation and reduce anxiety. Lavender essential oil can be diffused or applied topically to induce calmness and enhance sleep quality. Magnesium supplements may help regulate neurotransmitters involved in sleep-wake cycles. Additionally, melatonin, a hormone naturally produced by the body, can be taken as a supplement to regulate sleep patterns. Herbal teas like peppermint or lemon balm can also aid in relaxation before bedtime. However, it's essential to consult with a healthcare professional before incorporating any new supplements into your routine.
