Why do I feel sleepy after I eat?

In this brief article, we are going to answer the question “why do I feel sleepy after I eat?”.We will also discuss some other factors that make you feel sleepy. In the end, we will discuss how to prevent sleepiness after eating.

Why do I feel sleepy after I eat?

You may feel sleepy after eating because some foods may induce sleepiness by stimulating the body’s synthesis of serotonin (the sleep hormone). For instance, eating meals that are rich in tryptophan (an amino acid) might cause you to feel sleepy.

Tryptophan is required for the synthesis of serotonin, which is the hormone responsible for inducing sleep.

Drowsiness is a potential side effect of serotonin when it is found in the brain in high enough concentrations. Cheese, spinach, salmon, egg, soy are the examples of foods that are high in tryptophan content.

Consuming meals high in sugar may lead to an increased release of insulin, which in turn leads to an increase in the amount of tryptophan found in the brain. This results in an increase in the synthesis of the neurotransmitters melatonin and serotonin, which both contribute to a feeling of calm and help regulate sleep.

More than 90% of the serotonin in the human body is located in the gastro-intestinal tract, which is where the hormone is responsible for regulating bowel motions.

Are there any other factors that make you feel sleepy?

Foods that are high in carbohydrates, including rice, pasta, bread, as well as potatoes, may also cause an increase in serotonin levels, which will make you feel sleepy.

As a result of the rapid absorption of processed meals by your body, which results in a rise and subsequent dip in blood sugar levels, you may also experience feelings of exhaustion after consuming these types of foods.

Consuming food should provide a boost to your energy levels. After eating a meal, it’s not unusual to feel sleepy for a short period of time. However, if this happens to you on a regular basis, it can be cause for worry. When a person has adrenal fatigue, this symptom almost always occurs.

Other causes of post-meal sleepiness include inflammation, consuming processed meals high in carbs and tryptophan, food sensitivities, consuming a massive high-fat meal, and the existence of health disorders such as diabetes, hypothyroidism, anemia, and sleep apnea.

Extreme tiredness or drowsiness that happens many times a day may be a symptom of a difficulty with sleep or another health issue.

How to prevent sleepiness after eating?

The first thing we need to do is to carefully examine our diet to check that we are consuming the right amount of nutrients for our body. Your energy levels may dramatically increase and you can avoid feeling tired after meals if you consume a diet rich in nutrients designed for people with adrenal fatigue.

Stick to nutritious foods and avoid junk food.

The rapid digestion of the refined carbohydrates included in processed meals causes blood sugar levels to surge and then drop, adding to overall feelings of fatigue. Make the conscious decision to have more meals that are invigorating and contain foods high in iron (leafy green vegetables), lean proteins (meat, fish, eggs), and complex carbs (whole grains, legumes).

Be aware of how much food you should be eating.

Consuming more food than you need will not only cause your digestion to slow down, but will also leave you feeling bloated and uncomfortable. This may easily lead to a state of lethargy. To prevent feeling drowsy and sluggish and to further control blood sugar levels, you could choose to eat smaller portions in between to relieve the stress of your eating schedule.

Limit sugars and fats

If you want to prevent an energy crash, you should make an effort to limit the amount of sugar and fat that you get from processed meals. Sugars may offer you an initial rush of energy, but that spike will shortly wear off, leaving you feeling excessively exhausted and worn out.

After lunch, if you have a craving for anything sweet, you should always try to eat at least one or two pieces of fruit.

Eat fewer carbohydrates.

Tryptophan is an amino acid that has been connected to a variety of processes that are beneficial to sleep. Tryptophan-containing foods are beneficial to sleep. Be careful to cut down on the amount of carbohydrates you consume at each meal.

Your noon meal should consist of 50 % vegetables, 25 % proteins, and 25 % carbohydrates. Reduce your protein intake as well, since this macronutrient contributes to overall body tryptophan levels.
