In some countries when winter months come, the lack of sunlight means a different in health. Some people are more grumpy in the winter, but some suffer from terrible depression. They have discovered that this condition is due to the pineal gland not being stimulated which happens naturally when we are in the sunlight.
Behind the forehead, lives the pineal gland. It is not very big, but its function is imperative to our sleep patterns and our moods. When sunlight hits the pineal gland, it stimulates the production of seratonin and melatonin – two things essential for good sleep patterns and mood. When there is no sun for long periods of time, the body can stop producing these two which can have a huge impact on our health.
