Home remedies for feeling sleepy after lunch: a lighter plate, a short walk and buttermilk

That heavy, yawning slump around 2–3 p.m. makes afternoons at work or study hard. These home remedies for feeling sleepy after lunch rebalance the plate, add a short walk and a glass of spiced buttermilk, and fix the night sleep that often sits behind the slump.

Why lunch makes you drowsy

A natural dip in alertness happens in the early afternoon. A large meal rich in refined carbohydrates (white rice, naan, sweets), fried food, dehydration and short night sleep make it much stronger. Constant excessive sleepiness, though, can point to sleep apnoea, anaemia, thyroid problems or diabetes.

Ayurveda describes heaviness and sleep after food as kapha, and recommends a moderate lunch, digestive spices and a short stroll (shatapavali, 'a hundred steps') after eating.

Ingredients

1 glass buttermilk (chaas)
¼ teaspoon roasted cumin powder, a pinch of black salt, a few mint leaves
A balanced plate: half vegetables and salad, a quarter dal, paneer, egg or other protein, a quarter roti or rice

How to prepare

Whisk the buttermilk with roasted cumin, black salt and crushed mint.
Plate the vegetables and protein first, then add a moderate portion of grains.

How to use

Eat lunch slowly and stop when you are about three-quarters full.
Walk for 10 minutes after eating, indoors or out.
Sip the spiced buttermilk with or after lunch instead of a sweet drink.

Helpful habits

Sit near daylight or step outside for a few minutes after lunch.
Drink water through the morning; mild dehydration adds to fatigue.
If you nap, keep it under 20 minutes and before 3 p.m.

Precautions

See a doctor if you feel very sleepy all day, fall asleep while driving or talking, snore loudly, or have unexplained tiredness, weight change or thirst.
People with diabetes should discuss after-meal sleepiness with their doctor, as it may relate to blood sugar.
Avoid multiple cups of tea or coffee to fight the slump; they can disturb night sleep.
