The primary function is that pineal gland secretes melatonin. This hormone is the primary one that controls your sleepiness and wakefulness. Natural light tends to turn this gland on. When the pineal gland is activated, your brain moves from sleeping to a state of wakefulness.
Frittata is an egg-based Italian dish similar to an omelette or crustless quiche, enriched with additional ingredients such as meats, cheeses, vegetables or pasta. The word frittata is Italian and roughly translates to fried.
Pour the filling into the prepared pie pan. Bake for 40-45 minutes, or until a toothpick inserted comes out clean. The frittata will rise while baking, but should settle back down once you remove it from the oven. Remove from the oven and allow the frittata to rest for at least 5 minutes.
