Explanation:
Beta waves, which have a high frequency and low amplitude, are frequently seen in awake people. They have a stimulating effect and are engaged in conscious and logical thought.
<u>Let us discuss beta waves in detail</u>
Focus is made possible when there are enough beta waves in our brains. The prominence of this wave produces anxiety, high arousal, an inability to relax, and tension, whereas its suppression can contribute to ADHD, daydreaming, sadness, and poor cognition. Beta waves aid with conscious focus, memory, and problem-solving under ideal circumstances. These waves can be categorized into three different groups.
- Low beta waves (12–15 Hz), referred to as "beta one" waves, are mostly linked to quiet, inward-looking attention.
- Beta two waves, or mid-range beta waves (15–20 Hz), are linked to energy, anxiety, and performance increases.
- High beta waves (18–40 Hz), also referred to as "beta three" waves, are connected to high levels of stress, anxiety, paranoia, vigour, and arousal.
