Side Effects of Tea: Still Addicted to Tea in Summer? Here's Why It Could Be Harmful

Many of us start the day with a hot cup of tea – the aroma, the flavor, the energy it gives. But drinking tea frequently in summer can actually do more harm than good. The caffeine and heat from tea can affect your hydration, digestion, and even your mental and heart health during the hotter months.

Let’s break down the top 5 reasons why tea may be bad for you in summer, and what healthier alternatives you can try instead.


1️⃣ Increases Dehydration

Your body loses more water in summer due to sweat. Tea contains caffeine, which is a diuretic and makes you urinate more, further dehydrating the body. This can lead to headaches, fatigue, or dizziness.


2️⃣ Upsets Digestion

Tea can trigger acidity, bloating, and gas—especially when consumed on an empty stomach. In the summer heat, this can worsen and may even cause acid reflux or ulcers over time.


3️⃣ Disturbs Sleep & Mood

Caffeine can disrupt your sleep cycle, and in the summer, it can cause restlessness, irritability, and insomnia, making it harder for the mind and body to relax.


4️⃣ Risky for Heart and Blood Pressure

People with high blood pressure or heart conditions should avoid too much tea in summer. Caffeine can raise your heart rate and increase the risk of cardiovascular issues.


5️⃣ Raises Body Temperature

Tea increases internal body temperature, which can make you feel more sweaty, tired, or dizzy—especially if you’re outdoors or working in heat.


What to Drink Instead?

For a healthy start to your day in summer, try:

  • Lemon water

  • Coconut water

  • Buttermilk (chaas)

  • Caffeine-free herbal teas

These drinks cool the body and help maintain hydration.
