Wake-up!!!

There are many changes in your body in the morning. After sleeping, your body is weak, and over a short period of time, it fixes this problem. Right when I wake up in the morning, I tend to notice that my arms and legs are weaker than during the day. Once, my alarm went off and I went to quiet it down. As I walked back to my bed, my legs gave away and I fell. During the night, my muscular system relaxes, when I suddenly use  them again, it is weak. Also, the moment I wake up, I open the curtains. The sunlight streams into my room, making everything bright. My eyes hurt from the bright light, and I have to shade my eyes so that it doesn't hurt as much. This happens because during the night, everything is dark and my pupils are bigger, allowing more light in. However when I first wake up, my eyes in the nervous system tells me that the combinations of allowing more light into my eyes and the large amounts of light in the room make it too much for my body to take in.

Negative feedback loops are working to make sure that the changes I experience aren't too extreme. The constant effort of trying to maintain homeostasis keeps my body ready for changes throughout the day.
