How to prevent tiredness in class

To prevent tiredness in class, consider the following tips shared by Andrew Huberman:

1. Posture: Standing up or having an upright posture can increase alertness. Neurons in your brainstem (specifically, the locus coeruleus neurons) release norepinephrine and epinephrine, which keep you alert when standing or moving 1.

2. Visual Attention: Position your learning materials or screens at eye level or slightly above. This helps maintain alertness by reducing the tendency to look down, which can promote sleepiness 1.

3. Workspace Brightness: Ensure your environment is well-lit. Bright light, especially natural light, can significantly enhance alertness and reduce tiredness 1.

4. Hydration: Drinking fluids moderately but consistently can help maintain focus. Avoid excessive fluid intake as it might become distracting due to frequent restroom breaks 1.

These strategies can help boost your alertness and reduce tiredness during classes.
