Do you find it hard to get out of bed in the morning on cold days? It's not surprising—the cold weather makes us not want to leave warm beds. But what else makes it so hard to get up in winter?
Another big reason is not having enough sunlight. Some hormones(激素) in our body affect(影响) our sleep. For example, melatonin(褪黑素) makes us sleepy, while cortisol(皮质醇) makes us feel awake. Sunlight helps us wake up by producing(产生) less melatonin and more cortisol. In winter, the sun rises later and there are fewer hours of daylight, so it is harder for us to wake up.
Also, our habits may change when the days are colder and darker. We may eat less fruit and vegetables, enjoy more sweet food, and not exercise so much. These changes can make us have less energy and make it even harder to get up early.
These tips may help you get up in winter:
●Set a sunrise alarm clock(闹钟). The clock slowly lights up your room like the sun. This can help wake up your body when the alarm clock rings.
●Put your alarm clock far from your bed so that you have to get up to turn it off.
●Set your heat(暖气) on before you wake up. This will make your room warm and comfortable when you get out of bed.
●Keep a glass of water by your bed and drink it when you wake up. It will help your body feel more awake and ready to move.
