According to
Why does my child always seem to get sick at night? - DrGreene.com, thehy mention that "...our bodies are on a 24 hour clock called the Circadian Rhythm. Hormone levels rise and fall according to this daily cycle. Some hormones help us to wake up in the morning, others help us to sleep at night. These same hormones affect how we feel pain. During the day high levels of cortisol, a stress hormone, keep us from feeling some of the pain and keep our fevers in check. At night our fevers rise and our discomfort increases. As if this weren't enough, throughout the day our senses are barraged by gigabytes of stimuli every second, and our brains are busy processing all the data. At night the amount of stimuli we are bombarded with is drastically reduced. This gives our brains an opportunity to pay more attention to this already increased level of pain. These factors combine to greatly amplify symptoms at night. Feeling better in the morning doesn't mean that you are better.[/quote]
Pretty cool.
