All of you probably know what the human 'circadian cycle' is, and depending on your personality, you would either be a night-owl or a morning-lark.
I am interested in understanding the patterns of alertness and tiredness throughout the entire day, between waking up and sleeping.
Personally, my alertness gears up in the morning until 12.30 pm, after which I will, consciously or not, begin to feel very very drowsy. This happens even in the absence of lunch (lunch makes people feel tired because the body works to break down the carbohydrates). I will continue feeling tired and exhausted throughout the entire afternoon before I become alert again from 5 pm onwards. And then of course, in the night I am quite alert.
Here are my questions:
- Has research been conducted on this?
- Are there strategies to alter the patterns?
- Does the tiredness have to do with eating patterns?
- What are the relationships between tiredness and our circadian cycles?
