Is this a pattern?: If you have consistent symptoms which occur only at a certain time of day, these symptoms may be related to hormonal cycles that we all experience on a 24 basis. This is called your circadian rythym. For example, people tend to have more parasympathetic activity at night and parasympathetic activity can lead to runny nose, watery eyes, scratchy throat - all "cold symptoms".
