Why a beautiful Sunrise always makes you feel extremely happy?

It has been proven that watching the sunrise or sunset gives you a better sense of gratitude for the earth. When you are caught up in the natural beauty of the Earth (like a sunset or sunrise), you rid yourself of any distractions and feel higher levels of satisfaction and gratitude for what's happening in front of you. I think if a person enjoys sunrises more than sunsets it means that they prefer to focus on what’s to come, rather than what’s already in their past.
