Dehydration:
In summer, you sweat a lot, which quickly reduces water levels in your body. This leads to a dry mouth. When there's less saliva, the delicate skin inside your mouth gets easily damaged, causing ulcers.

Food Habits:

We often crave spicy, masala-heavy foods or acidic fruits and drinks to feel cool in summer. But these can irritate the soft lining of your mouth and lead to painful sores.

Simple Ways to Prevent Mouth Ulcers:
Drink at least 3 to 4 litres of water daily to keep your mouth moist. Have cooling drinks like tender coconut water and buttermilk. Avoid spicy, sour, and fried foods. Instead, add iron-rich greens, fruits, and whole grains to your diet. Use a soft-bristle brush, gargle daily, and try to get 7 to 8 hours of sleep. These simple steps help your body heal and prevent ulcers.
