Some people wake up before the sun rises above, go for a run and eat a healthy breakfast, all before many others get out of bed. Waking up that early might sound tiring to late risers, but can a night owl (夜猫子) become an early bird?

“It is possible to make the change, but it’s not easy,” said Michelle Drerup, director of behavioral sleep medicine at the Cleveland Clinic. “A true night owl doesn’t really feel great early in the morning when they wake up, especially when they’re starting to change this.”

A person’s tendency to be a night owl, early bird or some kind in between is known as their chronotype (生物钟). Depending on that, people are likely to be more awake during certain times of the day and sleepier during others. It is determined by a combination of nature and life style, scientists have found.

If you want to wake up earlier, make the change gradually. Drerup recommended slowly setting your wake-up alarm earlier by 15 to 20 minutes every few days over the course of several weeks until you’re adjusted to your schedule. Sticking to it is the key.

“Limit exposure (接触) to light in the hour before bed, such as by staying away from screens,” Drerup said. Light blocks the body's production of melatonin (褪黑色素) which is thought to set our circadian rhythm (昼夜节律). And in the morning, try to get exposure to light as soon as you wake up, to end melatonin production. Avoid exciting activities late in the evening. Instead of exercising at night, try working out in the morning or afternoon. You may also need to change your meal times to earlier time in the day.

If being a night owl works for you, there is actually no need to change your sleep schedule. But staying up late becomes a problem when you must wake up early for work and school. It can also increase your risk of developing health.

After millions of people around the country fill themselves with turkey and potatoes on Thanksgiving, they will wake up and think "I feel fat".

There are three psychological reasons that make someone more likely to"feel fat". The first is a high degree of internalization (内化).【小题1】. Media images prefer a thin ideal for women or a muscular ideal for men. When you internalize it, you’ve taken what society said people should look like. The second is self-objectification. People tie their overall self-worth to their physical appearance.【小题2】You' re extra sensitive to anything that could be taken the wrong way. So if something's going on in either their environment or their bodies that makes them feel a certain way, they're more likely to respond strongly to it.

【小题3】 You really are a little more bloated (浮肿)than usual. Maybe something strange is going on in your stomach that's making you a little gassy (胀气). Even drinking a ton of water can make you more bloated than usual. All are purely physical reactions that can cause that "I'm feeling fat" fear.

【小题4】And that expectation is kind of baked into the DNA of Thanksgiving itself. It's such a part of our culture to be sort of undervaluing our own bodies. This sense of "Oh, I'm so fat" or "Oh, I just ate so much" is culturally permitted. We can feel fat, in other words, because we think we should. It's valuable to emphasize that it's okay to enjoy food across the holidays. It's Thanksgiving.   【小题5】And this time，that boat is filled with gravy(肉汁).

With all the wars, fighting and sadness in the world today, it's not only necessary, but also essential to have a good sense of humor just to help us get through each and every day of our lives. Putting a smile on someone's face when you know they are feeling down in the dump, makes me feel good and warms my heart.

How would you feel if you could not joke around with your wife, husband, child, co- workers, neighbors, close friends, or even just someone that you are standing in line with at your corner store? I am always saying things that make others smile or laugh, even if I don't know the person I'm joking around with. My Grandma always found humor in everything she did, even if it was the hardest job anyone could imagine. This not only relieves stress in any situation, but also is common courtesy(礼貌) to speak to others that are around you.

I know of a few people that don't have a funny bone in their bodies, as they say. Everyone around them could be rolling on the floor after hearing a great joke and they would sit there without the slightest smile on their face. They don't get the joke that makes others laugh. I am busting a gut while they just sit there, looking at me as if I were from outer space. How can people not get a really funny joke?

Laughing is essential to keep your stress levels under control. Without humor we would find ourselves with a lot of psychological problems, or on a lot of medications to keep us from going crazy. There is too much sadness in this present world. It drives people crazy. We all need to find a way to ignore the sadness and bring a little light into our lives. So，I believe our best medicine is to get together and tell some jokes and have some fun laughing together.
