Why A Glass Of Lassi Makes You Feel Drowsy

Popular across India, lassi is often enjoyed during hot summers for its hydrating and digestive benefits. Yet, its tendency to make people feel sluggish or sleepy has intrigued nutritionists, who point to biological and dietary reasons behind this phenomenon.  

Nutritional Composition  

Lassi contains tryptophan, an amino acid that helps the body produce serotonin and melatonin-chemicals that regulate mood and sleep. This natural process can trigger relaxation and mild drowsiness after consumption.  

Digestive Impact  

The thick consistency of lassi, often sweetened with sugar, makes it heavy to digest. As the body diverts energy toward digestion, it can leave you feeling sluggish and ready for rest.  

Sugar And Fermentation Effects  

Added sugar can cause blood sugar spikes followed by dips, leading to fatigue. Fermentation in yogurt produces lactic acid, which may also contribute to feelings of tiredness in some individuals.  

Lifestyle Context  

Moderation is key. Opting for lighter, unsweetened versions of lassi or pairing it with balanced meals can reduce drowsiness while still offering its cooling benefits.  

Key Highlights  

• Lassi contains tryptophan, aiding serotonin and melatonin production  
• Heavy digestion contributes to sluggishness  
• Sugar spikes and dips cause fatigue
