Summer in India often crosses 49°C, driving a sharp rise in ER visits for heatstroke and dehydration. Last summer (March–June 2025), official NCDC data recorded 7,192 suspected cases and 14 confirmed deaths. This isn’t just seasonal discomfort; dehydration, heat exhaustion, and electrolyte imbalance are real clinical risks. At Artemis Hospitals, experts provide smart nutrition and hydration tips to patients.
To start with, in this blog, we will walk you through the benefits of consuming the best summer foods and drinks. While this blog provides information for general awareness, it is important to consult your dietician in case you have allergies to certain drinks, are on medication, or have pre-existing medical conditions to avoid any adverse reactions.
What Happens to Your Body in Extreme Heat?
As the temperature increases, your body works overtime to maintain its normal internal temperature. Sweating increases, which shifts the blood flow, and hydration levels drop quickly, putting significant stress on multiple organs. Prolonged exposure to extreme heat can overwhelm these natural cooling mechanisms, leading to serious health risks if not managed properly.
Here are the harmful effects of extreme heat:
- Dehydration
- Heat exhaustion
- Heatstroke
- Electrolyte imbalance
- Low blood pressure (hypotension)
- Dizziness and fainting (syncope)
- Muscle cramps (heat cramps)
- Kidney stress or injury
- Worsening of existing medical conditions
- Fatigue and reduced physical performance
Why is Hydration Critical in Summer?
The human body loses fluids rapidly through sweat, which happens in an effort to stay cool. As a result of constant fluid loss, which is not often replenished, normal body functions can be disrupted. Staying well-hydrated becomes essential to help your body cope with the added stress of extreme heat. Drinking plenty of fluids helps in the following:
- Regulating body temperature
- Preventing dehydration and heat-related illnesses
- Maintaining electrolyte balance
- Supporting kidney function
- Aiding digestion and nutrient absorption
- Keeping energy levels stable
- Preventing headaches and dizziness
- Supporting healthy skin and overall well-being
What are the Best Summer Drinks to Stay Hydrated & Energized?
The best summer drink is the one that keeps you hydrated, maintains the internal temperature of the body, and balances the electrolytes in the body. Water is the first essential thing in summer. Drinking plenty of water helps you stay hydrated, and you can avoid any adverse effects of summer heat. But if you want more than just water to make sure you get other benefits from your drinks too.
Here we have listed the best summer drinks to stay hydrated:
Chaach
Chaach (Buttermilk) is a light, probiotic-rich drink made from diluted curd, often seasoned with cumin or mint. What makes it healthy is its good bacteria, calcium, and electrolytes, which support digestion and hydration.
In summer, it helps cool the body, reduces acidity, and prevents dehydration-related fatigue. It’s especially useful after meals or during the day to maintain gut health and fluid balance.
However, people with lactose intolerance or sensitive digestion should consume it cautiously. The best way to have chaach is fresh and homemade, with minimal salt; avoid packaged versions with additives. Ideal times include mid-morning or post-lunch for better digestion.

Aam Panna
Aam Panna, a traditional summer drink made from raw mangoes. What makes it healthy is its rich nutrient profile (Vitamin C, potassium, and electrolytes) that helps replenish what the body loses through sweat.
During intense heat, aam panna supports hydration, improves digestion, and helps prevent issues like fatigue, heat exhaustion, and dehydration.
Keep it light, avoid too much added sugar or salt and enjoy it ideally in the morning or after coming in from the sun to help your body recover and rehydrate effectively.
Bael Juice (Wood Apple)
A traditional summer drink made from the pulp of the bael fruit, known for its cooling and gut-friendly properties. What makes it healthy is its rich fiber content, vitamin C, and antioxidants that support digestion and hydration.
In summer, it helps prevent heat-related issues like dehydration, acidity, and digestive discomfort while also soothing the stomach lining.
It can be especially helpful in managing loose motions or heat-induced gut problems. However, people with chronic constipation or those on specific digestive medications should consume it in moderation.
The best way to have bael juice is freshly prepared at home without excess sugar; avoid packaged versions with preservatives. It’s ideal to consume it in the morning or mid-day for maximum cooling benefits.
Saunf Sharbat (fennel drink)
The drink has natural cooling and digestive properties, making it a popular summer refresher. Rich in antioxidants and compounds that aid digestion, it helps reduce body heat, bloating, and acidity.
During hot weather, it supports hydration and provides a calming effect on the stomach, especially after heavy or spicy meals. While generally safe, individuals with fennel allergies or sensitivities should be cautious.
For best results, prepare fresh at home and keep added sugar minimal. It is best consumed mid-day or after meals to aid digestion and help the body stay cool.
Sabza Paani (Basil Seed Drink)
Made by soaking sabja seeds, which swell into a gel-like texture. What makes it healthy is its soluble fiber, cooling effect, and mild electrolyte support. In summer, it helps reduce body heat, improves satiety, and supports digestion while aiding hydration.
This drink can also help curb overeating in hot weather. However, it should be consumed in moderate quantities, especially by those with swallowing difficulties or digestive sensitivities.
The best way to have sabza paani is by soaking the seeds properly and adding them to water or light drinks; avoid excess sugar. Ideal time is mid-morning or afternoon for a cooling effect.

This fruit juice is rich in water content (over 90%) along with vitamins A and C and antioxidants like lycopene. These nutrients help maintain hydration, support skin health, and reduce fatigue during extreme heat. It acts as a natural coolant and helps replenish fluids quickly.
However, people with blood sugar concerns should moderate intake due to natural sugars. Freshly cut fruit or juice is always better than packaged versions with added sugar. Best consumed between meals or mid-day for optimal hydration.
Lassi (A Yogurt-based Drink)
Rich in probiotics, calcium, and protein, making it both nourishing and cooling. In summer, it supports gut health, aids digestion, and helps prevent dehydration while keeping you full and refreshed.
Sweet or salted lassi versions can both work, but excess sugar should be avoided. Also, individuals with lactose intolerance should be cautious or consult a dietician before consuming it.
The best option is fresh, homemade lassi with controlled sugar or salt. Ideal time is after meals, especially lunch, to aid digestion and cooling.
Kanji
A traditional fermented drink made from vegetables like black carrots, rich in probiotics and antioxidants. What makes it healthy is its ability to support gut health, improve digestion, and enhance nutrient absorption.
In summer, it helps maintain hydration and boosts immunity while offering a tangy, refreshing taste. However, those with very sensitive stomachs should start with small amounts due to its fermented nature.
Freshly prepared kanji is best, without preservatives. It’s ideal to consume in small quantities during the day, especially before or with meals.
Methi Dana Paani / Jeera Paani
These are simple infused waters made by soaking fenugreek seeds or cumin seeds. They are known for their digestive benefits, anti-inflammatory properties, and mild cooling effect.
In summer, they help reduce bloating, support metabolism, and keep the body hydrated. However, methi water may not suit everyone, especially if consumed in excess, and should be taken cautiously by those on specific medications.
The best way is to soak the seeds overnight and drink the water fresh in the morning on an empty stomach.
Lemon Water with Iron-Rich Foods
A smart dietary combination rather than just a drink. Lemon is rich in vitamin C, which enhances the absorption of iron from foods like leafy greens, pulses, and whole grains.
In summer, this combination not only supports hydration but also helps prevent fatigue and weakness linked to low iron levels. However, excessive lemon intake may trigger acidity in some individuals.
The best approach is to add fresh lemon juice to meals rather than relying on packaged drinks, ideally during lunch or main meals for better nutrient absorption.
Who Needs Extra Hydration in Summer?
Not everyone loses fluids at the same rate. During extreme heat, certain groups are more vulnerable to dehydration and heat-related complications, and they need more careful, consistent hydration to stay safe.
Children
Children experience peak heat impact during midday hours, typically between 11 AM and 3 PM, when UV radiation is strongest and temperatures reach their highest. During these critical hours, their bodies are highly vulnerable to dehydration and heat exhaustion.
Consuming a summer drink, such as coconut water, lemon water, or fresh juice, provides essential electrolytes and hydration. Having lunch at this time replenishes energy and nutrients while the body needs them most. A balanced meal with cooling foods like yogurt, and fruits helps regulate body temperature, maintaining optimal health and energy levels throughout the day.
Elderly
Elderly people face even greater heat vulnerability as their bodies have a reduced ability to regulate temperature and sweat less effectively, making them prone to heat stroke and dehydration. Consuming hydrating drinks like coconut water, buttermilk, or herbal tea is essential for maintaining fluid balance.
A light, nutritious lunch, such as cucumber, melons, yogurt, and leafy greens helps prevent heat-related illnesses. Regular small meals and frequent sipping of water throughout the day keeps their bodies cool and prevents dangerous complications, ensuring their safety and well-being during summer months.
Outdoor Workers
Outdoor workers face severe heat stress when performing physically demanding tasks. Their bodies lose excessive fluids through perspiration, increasing dehydration and heat exhaustion risks.
Consuming electrolyte-rich drinks, such as coconut water, fresh fruit juice drinks, or salted lemon water replenishes lost minerals and fluids rapidly. A substantial, protein-packed lunch, like legumes, whole grains, and fresh vegetables, provides sustained energy.
Taking regular breaks in shaded areas, eating at cooler times (early morning or late afternoon), and maintaining consistent hydration throughout the day significantly reduces heat-related illness, ensuring worker safety, productivity, and long-term health.
Patients with Diabetes
Diabetic patients face heightened heat vulnerability because extreme temperatures affect insulin absorption and blood sugar levels. Heat accelerates insulin metabolism, potentially causing sudden drops in glucose levels, increasing hypoglycemia risk. Consuming sugar-free hydrating drinks, plain water or unsweetened coconut water maintains hydration without spiking blood sugar.
A balanced lunch with lean proteins, whole grains, non-starchy vegetables, and healthy fats stabilizes glucose levels effectively. Regular monitoring of blood sugar, eating at consistent times, staying hydrated, and avoiding sugary beverages are crucial for preventing complications and maintaining metabolic stability during summer months.
Patients with Kidney Disease
Patients with kidney disease face critical heat risks because their kidneys cannot efficiently regulate fluid and electrolyte balance. Excessive sweating and dehydration strain already compromised kidneys, potentially triggering acute kidney injury or disease progression.
Consuming appropriate fluids, limited quantities of water, coconut water (in moderation), or prescribed electrolyte solutions is essential under medical guidance. A kidney-friendly lunch featuring low-sodium foods, controlled protein portions, phosphorus-restricted items, and fresh vegetables supports kidney function.
Avoid excessive salt and potassium and schedule outdoor activities during cooler morning or evening hours are vital for preventing kidney complications and maintaining optimal health during summer.
Patients with Heart Conditions
Patients with heart conditions face severe heat-related complications. Extreme temperatures increase blood pressure and heart workload. Heat causes blood vessels to dilate, reducing blood circulation efficiency and straining weakened hearts.
Heart-healthy drinks, such as plain water, herbal tea, or low-sodium coconut water, prevent dehydration without overloading the cardiovascular system. A light, heart-friendly lunch is lean proteins, whole grains, low-sodium vegetables, and omega-3 rich foods that support cardiac function.
Don't perform outdoor activities during hot hours, maintaining consistent medication schedules, limiting salt and caffeine intake, and staying adequately hydrated are critical for preventing heart attacks and arrhythmias and ensuring cardiovascular stability during summer months.
What Do Doctors Recommend for Safe Hydration During Summer?
Doctors emphasize that proper hydration is fundamental to maintaining health and preventing heat-related illnesses during summer months. As temperatures rise, the body's fluid requirements increase significantly, yet many people fail to drink adequate water. Here are some tips to beat the heat this summer:
Drink Water Consistently Throughout the Day
Consume 8-10 glasses of water daily; increase during physical activity. Don't wait until you feel thirsty since thirst is an early indicator of early dehydration.
Choose Electrolyte-Rich Beverages
Coconut water, buttermilk, lemon water with salt, or oral rehydration solutions. These replenish minerals (sodium, potassium) lost through perspiration.
Avoid Sugary and Caffeinated Drinks
Limit sodas, energy drinks, and excessive coffee, they increase dehydration. Caffeine acts as a diuretic, promoting fluid loss.
Time Your Hydration Strategically
Drink smaller quantities frequently rather than large amounts at once. Pre-hydrate before outdoor activities; hydrate during and after exercise.
Monitor Urine Color
Pale yellow indicates proper hydration; dark yellow signals dehydration. Adjust fluid intake based on this simple indicator.
Eat Water-Rich Foods
Include cucumbers, melons, watermelon, oranges, and leafy greens. These foods contribute to 20% of daily fluid intake.
Customize Hydration by Health Condition
Avoid sugary drinks; consult our doctors about appropriate beverages. Follow prescribed fluid restrictions; use medical supervision. Also, limit sodium; avoid excessive fluid intake without guidance.
Stay Hydrated During Sleep
Keep water nearby at night; sip small amounts if you wake up. Morning dehydration is common; drink water immediately upon waking
Use Hydration Apps or Reminders
Set phone alerts to drink water at regular intervals. Track daily fluid intake to ensure adequate consumption.
Recognize Dehydration Symptoms
Dry mouth, excessive thirst, dizziness, dark urine, fatigue, headaches. Seek medical attention if symptoms persist or worsen.
