Pineal Gland

The pineal gland is a small, pea-shaped gland located deep inside the brain. Its primary role is to produce and regulate hormones, especially melatonin, which influences your sleep-wake cycle and circadian rhythms. The gland is sensitive to light, increasing melatonin production in darkness and decreasing it during daylight. This helps regulate sleep patterns, mood, and seasonal biological rhythms. Although small, the pineal gland plays an essential role in maintaining your body's internal clock, impacting overall health and well-being.
