Maybe you don't, but other people do. "I don't have that problem" isn't an excuse to not do anything about it.

Saapas, I can see that you were trying to relate your own experiences to the discussion and even add to the discussion by asking a question. I'm sorry that nobody seems to understand what you're trying to do. Many here are autists and many more are self-involved. I, in fact, am both and very pleased with myself for feeling empathy and compassion in this moment.

Back to your very valid question: Sleep scientists have long tracked sleeping cycles. Not all sleep is equal. Sleeping for a certain amount of time resets certain chemical imbalances in the brain. Many people can take a twenty-minute nap at midday, for example, and feel clear-headed afterwards. However, if they take an hour nap, they may feel lethargic. But then maybe that same person could take a two-hour nap instead, and feel great.

Your mileage may vary, but my point is that sleep cycles are a real thing. If your body is used to going to sleep at a certain time, that's the time it expects sleep. It's based on your body's own internal clock. Daylight Savings Time messes with that clock. Your body doesn't care that your phone jumped ahead an hour.

Not everyone will have a difficult time adjusting, but it's not uncommon to feel restless for a couple of weeks until the body catches up to the new sleep pattern.
