A Lie detector test measures changes in your body to identify if you are telling the truth. These changes include heart rate, breathing, and sweating. To get accurate results, you need to avoid certain actions before the test. Even small mistakes can affect the outcome and create misleading results.
People sometimes make poor choices before truth verification sessions because they feel nervous or unsure about what will happen. Knowing what to avoid can help you stay calm and give an honest, clear reading. Here are five important things you should never do before this type of examination.
- Do Not Take Stimulants or Alcohol
Caffeine, energy drinks, and alcohol can alter your body’s natural state. Stimulants may raise your heart rate, while alcohol may slow it down. Both can create false readings and make it harder for the examiner to read your responses accurately. - Do Not Stay Awake All Night
Lack of sleep can make you feel tired and stressed. Your concentration may drop, and your body might show unusual signs during questioning. Getting a full night’s sleep will help you stay alert and answer questions with a clear mind. - Do Not Try to Trick the Test
Some people believe they can fool a polygraph by changing breathing patterns or tensing muscles. These methods rarely work and can backfire. The examiner can spot unnatural patterns, and the session may end without valid results. - Do Not Skip a Meal
Being hungry can affect your mood and energy levels. Low blood sugar can make you feel anxious or shaky, which might be mistaken for signs of dishonesty. Eat a normal, balanced meal before the appointment to keep your body steady. - Do Not Arrive in a Rush
Rushing to the appointment can raise your stress level before the session even begins. Plan to arrive early so you have time to relax. Sitting calmly before starting can help keep your body in a normal state for accurate readings.
Avoiding these mistakes will help ensure the results are based on truth rather than physical distractions. A polygraph works best when your body is in a natural, relaxed condition. The more comfortable you are, the more likely the outcome will reflect your honesty.
Taking time to prepare properly shows you respect the process and the results. If the session is for a personal matter, legal case, or workplace issue, accuracy is crucial. Follow these steps, stay calm, and let the process work as it should.
