New Delhi India (UNA) :

As exams approach, students often reach for tea or coffee to stay alert. While a cup or two may feel like a quick energy boost, doctors say excessive caffeine can have unintended health effects that outweigh short-term benefits.

First, caffeine can increase anxiety and stress levels, making it harder to concentrate during long study sessions or in the exam hall. Higher stress hormones in the body can also affect mood and decision-making, which students rely on most during tests.

Second, too much caffeine especially later in the day can disturb sleep patterns. Good quality sleep is essential for memory consolidation and clear thinking. Without proper rest, students may struggle to retain information and stay focused.

Third, caffeine can cause jitteriness and rapid heartbeat, making it hard to sit still and focus for extended periods. In sensitive individuals, this can lead to discomfort and distract from studying or exam performance.

Finally, heavy consumption may result in headaches, stomach upset or dehydration symptoms that add to physical and mental strain.

For students and parents, the advice is simple: keep caffeine in moderation and avoid it late in the day. Balanced meals, short breaks, water and enough sleep can offer healthier ways to stay alert and sharp when it matters most.
