What makes you sleepy? While people don’t think much about why they fall asleep, but most of them acknowledge that sleep makes them feel better. People feel more energetic, happier, more alert, and perform better after a good nights’ sleep. 

Even scientists don’t know why everybody needs to sleep. They are pretty much clueless about the fact that it determines when the body needs to sleep. However, sometimes it may feel worse and miserable to feel sleepy. This lays the beginning of the explanation of why you need to sleep in the first place.

Why do we get sleepy?

Scientists have tried to answer this question from various angles. They have researched about the sleeping patterns of both humans and animals to find out what happens if they are deprived of sleep. Yet, after decades of discoveries and researches, they aren’t able to answer why people get sleepy.

However, the lack of a clear answer doesn’t mean all their efforts have been a waste of time. Scientists have developed promising theories to explain why people sleep. From all the evidence they have gathered, it appears that no single theory can be proven right. Sleep can be explained better by combining more than one explanation.

Inactivity theory – It is one of the earliest theories that suggest inactivity at night serves as a survival function to keep away from being vulnerable to other species. The theory reflects that species who remain quiet and still during this period, have an advantage over other species that remains active. 

Energy conservation theory – It may appear less apparent to people living in communities where food supplies are abundant but needs effective utilization for these natural resources. This theory puts emphasis on the fact that feeling sleepy reduces the demand for energy during part of the night and day when it is least important to look out for food.

Restorative theories – This is another popular theory where it explains about the age-old belief that sleep serves to restore whatever the body lost while it was awake. Sleep provides your body with the opportunity to repair and revitalize itself. Other rejuvenating aspects of feeling sleepy is that it improves the cognitive functions of your brain.

Brain plasticity theory – It is the most compelling and recent findings that sleep correlate to the changing structure of an organization of your brain. Known as brain plasticity, this phenomenon is yet to be understood entirely.

You tend to feel sleepy or have difficulty in concentrating soon after a meal. Feeling sleepy is very common after consuming some specific foods. Sleepiness also depends on what type of food, how, and when you eat. That’s the reason why some people feel tired and sleepy after a meal. 

The foods that are rich in carbohydrates and proteins will make you feel sleepy than any other type of food. Some researchers are of the opinion that a person’s body tends to produce more serotonin soon after eating. And, this is what makes them feel sleepy.

Serotonin plays an important role in regulating sleep cycles and regulating mood. Tryptophan helps your body to produce serotonin. It is an amino acid which is present in foods rich in protein. Carbohydrates help your body to absorb tryptophan.

Hence, when you eat a meal rich in carbohydrates and protein, it will make you feel sleepy. Tryptophan is found in foods that have an abundant supply of protein. This includes poultry, spinach, salmon, eggs, soy products, milk, cheese, and seeds. 

Foods that have higher levels of carbohydrates include rice, milk, pasta, white bread, corn cobs, sugar, candy, muffins, donuts, cookies, and cake. People tend to eat meals that contain both carbohydrates and proteins before bedtimes such as milk and cereals. 

A person may experience postprandial somnolence soon after a heavy meal. There are also people who eat larger lunches during the afternoon. Such people may feel sleepy than those who eat very less at midday. There is an increase in the blood sugar levels and your energy may fall after eating.

There are some other factors that may influence sleepiness after eating. This includes lack of sleep at night, which leads to tiredness the following day and drinking alcohol with foods, especially during the daytime.

Why can’t I sleep even though I’m tired?

In general, people tend to relate to tiredness and sleep. But, in reality, these are two different things. As you may have felt sometimes, feeling tired doesn’t make you fall fast asleep. On the other hand, feeling sleepy means that sleep is about to happen. So, how can you find out if you are sleepy-tired?

There are few signs and you need to watch out for them. These include lack of energy, itchy eyes, aching muscles, and yawning. When you head towards the bed without experiencing these signs, it is very likely that you won’t sleep quickly. You will lie awake and thinking about sleeping.

A very common thing for poor sleep is your active mind. It is considered as the main cause of sleeplessness. When you are holding on to past or future events of lesser importance, they will keep you away from sleep even if you are tired.

It isn’t only the thoughts that keep you away from falling asleep, but ingesting stimulants or exercising shortly before bedtime can deter sleep from settling in. Exercise boosts your energy levels and makes it hard for you to sleep. 

Most types of stimulants such as nicotine and caffeine can cause similar effects. Stimulant drugs make it difficult to lower arousal and ignite sleep. When you consume caffeine, it takes a longer time for you to fall asleep. 

When you are tired but can’t sleep, the only solution is to follow habits and activities that make you relax. They will help you to reduce over-arousal and allow sleep to take over wakefulness. Different people will find activities that will help them to relax. Therefore, find out exactly what will work best for you. 

Can you catch up on sleep?

No, you can’t do that. If you are thinking to get an extra shot of sleep so that you can overcome your sleep deprivation, it may seem like the best choice for you. However, a recent study by Harvard Medical School has found that it is not an easy task.

Their study lays emphasis on the impact of loss because of chronic sleep on performance. The study further reveals that it is not possible to catch-up on lost sleep for improving performance. According to the research, even if you sleep for about 10 hours for compensating your 6-hour sleep per night for about 2 weeks, your ability to focus and reaction time becomes worse. 

Whereas, an all-nighter might be useful. Now, that’s not a piece of good news for truckers, doctors, or law enforcement officers. The finish line is that there are no real ways to compensate for your lost sleep. Whatever is lost can’t be recovered by adding few hours of sleep.

However, there are some ways that shift workers may pull off if they want to get good quality sleep during their recess hours. For instance, maintaining the same wake-up and bedtime schedule even on weekends, wearing dark-colored glasses on their way home, and eliminating light and noise from the sleeping area.


Excessive sleep can attract severe consequences like dozing off at red lights while waiting. And, not getting enough sleep gives rises to heart diseases, high blood pressure, weight gain, and diabetes. The overall quality of life gets compromised by poor sleep.
