Tired after eating?
After a busy morning, lunch can feel like just something necessary but sometimes it also makes you want to take a break at your desk.
This is because when humans eat, our blood sugar level is raised after receiving energy from food, which may cause tiredness after meal. Feeling tired can make it hard to focus on the rest of your studies and activities. Here's why and how to improve the situation.
Some people overeat instead of stopping when they feel full. For example, when having buffet, people often eat more than they expect. Because we usually feel tired after working the whole morning without breakfast. This will make us eat more at lunch.
The make up of certain foods can also cause you to feel tired. If you had a meal high in fat, such as a hamburger or a pizza, that could make you feel tired. Meals high in added sugar can have the same effect.
If you don't get enough sleep, your body increases production of ghrelin, which sends a " feed me" signal to your brain. Not getting enough rest can also have a bad influence on your decision making skills.
A. It's normal to feel tired after lunch. B. So make sure you sleep for eight to ten hours every night. C. A common reason for feeling tired after a meal is eating too much. D. However, not eating breakfast can also lead to overeating later in the day. E. So taking a walk after a big meal is a great way to make you feel less tired. |
