Why do you feel sleepy after lunch?

Eating a heavy meal can easily make you feel sleepy after lunch. Know more reasons behind post-lunch fatigue and how to overcome it.

Isn’t it an everyday phenomenon? You start your day flushed with good energy, have your breakfast, and head to perform your routine duties. But after lunch, you feel a dip in your energy, and you feel like dozing off for a while. But if you are at work, resting can be hard. Has it ever made you wonder why you feel sleepy after lunch, and what can you do to overcome post-lunch fatigue?

Why is it common to feel tired after lunch?

It is quite common to feel sleepy after lunch. There are multiple reasons why it happens:

1. The digestion process takes energy

Firstly, digestion requires energy, so after a meal, your body redirects blood flow to your digestive system, which can make you feel sluggish, says Pulmonologist and Respiratory Medicine specialist Dr Arunesh Kumar. Your digestion process takes up most of your body’s energy, leaving you feeling sluggish after lunch.

2. Certain foods cause more sluggishness

Certain foods, like those high in carbohydrates or fats, can cause a spike in blood sugar followed by a crash, leading to fatigue, says the expert. Foods that are high in protein and carbohydrates make people feel more drowsy than other foods. Alongside, eating food produces serotonin in the body. Serotonin is a chemical that plays a vital role in enhancing your mood and sleep cycles. Also, an amino acid called tryptophan, which is found in many protein-rich foods, aids the body in producing serotonin. While carbohydrates help in the absorption of tryptophan. It is because of these that most people feel a lack of energy after having a lunch packed with foods rich in protein and carbohydrates.

Tryptophan is present in foods that have high protein and those include:

3. More insulin production

Eating a large meal can trigger the release of hormones like insulin, which can induce drowsiness. This can again be due to certain composition of foods. Certain foods are known to promote sleepiness due to their composition or the presence of specific compounds. For example, foods high in tryptophan, like turkey, dairy products, and nuts, can increase serotonin levels in the brain, promoting relaxation and drowsiness. Similarly, carbohydrate-rich foods can trigger the release of insulin, which promotes the uptake of tryptophan into the brain, further enhancing its sedative effects, says the expert.
