Facing your viva can feel overwhelming. After all the hard work writing your thesis, the thought of defending it aloud in front of experts can stir up serious stress. This kind of anxiety, known as viva stress, is common and manageable. In this article, we’ll explore why viva stress happens and share simple ways to prepare, calm your nerves, and walk into your viva with confidence.
What Is Viva Stress?
Viva stress is the anxiety people feel before their oral thesis defense, known as the viva. It’s a common experience for PhD students and often comes from the pressure to perform well, fear of failure, and uncertainty about what to expect.
The viva is the final checkpoint between years of research and earning your degree, and knowing you’ll be questioned on every part of your work can easily make the nerves kick in. Even the most confident researchers may feel overwhelmed because their work is deeply personal, and now, someone else gets to question it.
Why Does Viva Stress Feel So Intense?
Because it feels like your entire future is riding on how you explain your work in front of experts for a couple of hours. It’s not just an academic discussion; it feels like you’re on a stage, defending your identity as a researcher.
There’s a natural fear of being wrong or caught off guard, and most people aren’t used to handling high-pressure questioning. Even with strong research, the idea of needing to sound intelligent and quick on your feet can turn into a spiral of overthinking.
Signs You’re Feeling Viva Stress
If you’re losing sleep, avoiding your thesis, or constantly doubting yourself, there’s a good chance you’re feeling viva stress. This kind of stress can show up as physical discomfort like headaches, stomach issues, and a racing heartbeat, or mental struggles like trouble focusing or sudden fear of speaking.
It might start as a few nervous thoughts but can quickly turn into avoiding preparation altogether or second-guessing every part of your work. These are all signs that stress is getting louder than logic.

How to Get Ready Without Burning Out
The best way to deal with viva stress is to prepare in a smart and steady way instead of cramming or panicking. Start by rereading your thesis slowly and carefully, making notes where you feel unsure or disconnected.
List out the main arguments and findings in your own words and make sure you’re clear on why each decision was made. Practice talking about your thesis with someone who knows nothing about it—that will help you see how clearly you’re communicating. If possible, ask a peer or mentor to hold a mock viva with you to simulate the real thing and boost your confidence.
Smart Ways to Calm Your Nerves Before the Viva
The day before your viva, stop revising and focus on relaxing and resting your mind. A clear head will serve you better than last-minute cramming.
Take a walk, listen to music, or do something you enjoy to let your brain slow down. Try deep breathing exercises, or repeat calming phrases to yourself to stay grounded. Eat a healthy meal and aim to sleep well, because a rested brain thinks better than a tired one.
What to Do During the Viva to Stay Grounded
Staying calm during the viva comes from focusing on what you know, not what you’re afraid might happen. When a question is asked, take a moment to understand it fully before you answer.
If something isn’t clear, it’s okay to ask the examiner to rephrase the question. You’re allowed to take your time, and speaking slowly can help you stay in control. Remember, the examiners aren’t trying to trick you—they want to understand how you think about your work.

How to Handle Tricky Questions Like a Pro
Tricky viva questions are there to test your thinking, not to tear your work apart. If you don’t know the answer right away, stay calm and explain how you would approach finding it.
You can be honest about limitations in your work or areas that could be improved, as long as you explain your reasoning clearly. If a question catches you off guard, take a breath, gather your thoughts, and answer in a way that shows your understanding of the bigger picture.
After the Viva: What Comes Next?
Most people pass their viva with only minor corrections, so don’t assume the worst. Once the viva is over, you’ll get feedback and find out if any revisions are needed.
If changes are requested, they’re usually aimed at improving clarity or tightening arguments—not tearing your work down. After all the pressure and nerves, this step is often more of a tidy-up than a redo. Take a few days to recharge, then make your edits when you’re mentally fresh.
When to Ask for Help
If viva stress is affecting your daily life, your sleep, or your ability to focus, don’t wait—ask for help. Reach out to your supervisor, mental health services at your university, or even trusted peers.
Support systems exist for a reason, and you’re not expected to handle everything alone. Whether you attend a viva workshop or just talk to someone who’s been through it, that support can make all the difference.
Final Word
Viva stress is tough, but it doesn’t have to control you. The more you prepare with intention and treat yourself kindly, the easier it becomes to manage.
You’ve already done the hard part—writing a full thesis. Now it’s just about speaking clearly and calmly about what you already know. Talk to yourself like you’d talk to a friend: with encouragement, belief, and pride in how far you’ve come.
