Summer is a season where physical exhaustion from the heat, air conditioning fatigue, and poor sleep quality combine, often leading to a decrease in concentration, judgment, and work efficiency during desk work. Let's get through summer desk work with a juice that combines tryptophan and dopamine precursors, which are raw materials for brain neurotransmitters; MCT oil and glucose, which are energy sources for the brain; and anthocyanins and L-theanine, which improve cerebral blood flow. The Happilaff PB-01 can be charged via Type-C and is cordless, so you can make it right at your office desk.
Reasons for Decreased Concentration During Summer Desk Work
| Cause | Impact on Brain & Concentration | Countermeasure Foods |
|---|---|---|
| Physical exhaustion from heat | Decreased energy supply to the brain, impaired judgment | MCT oil, banana (immediate energy) |
| Air conditioning fatigue, autonomic nervous system imbalance | Over-activation of sympathetic nervous system â frequent fluctuations in concentration | L-theanine in matcha (calm alertness) |
| Decreased sleep quality | Reduced prefrontal cortex function â impaired judgment and creativity | Sour cherry, banana (sleep improvement) |
| Dehydration | Cognitive function declines with just a 1-2% decrease in brain water content | Cucumber, watermelon (hydration) |
Foods Effective for Concentration and Work Efficiency
| Food | Active Ingredient | Effect on Brain & Concentration |
|---|---|---|
| Matcha | L-theanine + Caffeine | Calm alertness, increased alpha waves, sustained concentration, reduced anxiety |
| Blueberries | Anthocyanins, Flavonoids | Improved cerebral blood flow, enhanced memory, strengthened cognitive function |
| Dark Chocolate | Flavanols, Theobromine, Caffeine | Increased cerebral blood flow, improved mood, immediate boost in concentration |
| MCT Oil | Medium-chain fatty acids (C8, C10) | Rapid ketone body production â immediate energy source for the brain |
| Walnuts | Omega-3, Polyphenols | Maintains flexibility of neuronal cell membranes, improves synaptic transmission |
5 Recipes for Summer Concentration & Work Efficiency Boosting Juices
ðµ Recipe 1: Matcha, Banana & Soy Milk Sustained Concentration Smoothie (Classic)
Ingredients: 1 tsp matcha, 1 banana, 250ml soy milk, 1 tsp MCT oil, 1 tsp honey
Instructions: Put all ingredients into PB-01, press the button for 20 seconds. Drink 30 minutes before starting work.
âš Effects: L-theanine + caffeine from matcha creates a calm state of alertness, increases alpha waves, and sustains concentration for 2-3 hours. Fewer concentration fluctuations and no jitters compared to coffee. MCT oil is quickly converted to ketone bodies, providing an immediate energy source for the brain. Ideal before starting work in the morning.
ð« Recipe 2: Blueberry, Walnut & Dark Chocolate Brain Blood Flow Boost Juice
Ingredients: 120g frozen blueberries, 20g walnuts, 15g dark chocolate (70%+ cacao), 200ml soy milk, 1 tsp honey
Instructions: Put all ingredients into PB-01, press the button for 25 seconds. Drink during morning work.
âš Effects: Flavonoids in blueberries increase blood flow to the brain's hippocampus, improving memory and learning ability. Flavanols in dark chocolate immediately improve overall cerebral blood flow. Omega-3 in walnuts strengthens neuronal cell membranes and optimizes synaptic transmission.
ð Recipe 3: Lemon, Ginger & Mint Refreshing Alertness Juice
Ingredients: 2 tbsp lemon juice, 2 slices ginger, 10 mint leaves, 1/2 green apple, 350ml water, 1 tsp honey
Instructions: Put all ingredients into PB-01, press the button for 20 seconds. Drink when afternoon drowsiness sets in.
âš Effects: Menthol in mint stimulates the brain through olfaction, immediately boosting alertness and attention. The scent of lemon (limonene) moderately increases cortisol, restoring concentration. Ginger promotes blood circulation, improving oxygen supply to the brain. Highly effective for afternoon drowsiness and decreased concentration.
ð¥ Recipe 4: Avocado, Matcha & MCT Oil Sustained Focus Ketone Juice
Ingredients: 1/4 avocado, 1 tsp matcha, 1 tsp MCT oil, 250ml soy milk, 1 tsp honey, a pinch of salt
Instructions: Put all ingredients into PB-01, press the button for 20 seconds.
âš Effects: Good fats from avocado + ketone bodies from MCT oil provide stable, long-lasting energy to the brain. Prevents sudden spikes and crashes in blood sugar, avoiding afternoon drowsiness and decreased concentration. L-theanine in matcha maintains a relaxed state of focus for an extended period. Ideal for long meetings or before deadlines.
ð Recipe 5: Pomegranate, Blueberry & Rosemary Memory Boost Juice
Ingredients: 100ml pomegranate juice, 80g frozen blueberries, 1 sprig rosemary (leaves only), 1 tsp lemon juice, 150ml water
Instructions: Put all ingredients into PB-01, press the button for 20 seconds.
âš Effects: 1,8-cineole in rosemary inhibits acetylcholinesterase in the brain, increasing acetylcholine (a neurotransmitter for memory and learning). Ellagic acid in pomegranate + anthocyanins in blueberries reduce oxidative stress in the brain. For presentations or important meetings.

View DetailsFrequently Asked Questions (FAQ)
- Q1. Is it okay to blend MCT oil with the PB-01?
- Yes, MCT oil is liquid, so it can be blended directly with the PB-01. However, it's recommended to start with 1/2 teaspoon. Consuming a large amount of MCT oil suddenly may irritate the stomach and intestines, potentially causing loose stools. Gradually increase to 1-2 teaspoons over 1-2 weeks.
- Q2. Until what time can I drink matcha juice?
- It's recommended to avoid caffeine from matcha within 6 hours of bedtime. If you go to bed at 10 PM, refrain from matcha-infused juice after 4 PM, and choose caffeine-free recipes like lemon & mint or pomegranate & blueberry instead.
- Q3. Can rosemary be blended with the PB-01?
- Rosemary leaves (excluding the stems) can be blended with the PB-01. Use only the leaves and remove the stems. As it has a strong aroma, try a small amount (leaves from 1 sprig) first. Combining it with blueberry and pomegranate juice can mellow the distinct rosemary aroma, making it easier to drink.
