feeling easily tired after doing online classes and excessive screentime due to study

Feeling easily tired after online classes and excessive screen time can be influenced by posture and workspace setup, as explained by Andrew Huberman in the Huberman Lab.

Tips to combat fatigue:

1. Adjust Posture: Standing up or moving can activate neurons in the brainstem (locus coeruleus) that release norepinephrine and epinephrine, which enhance alertness. Sitting down reduces this activation, and lying down increases the firing of neurons that promote sleep 1.
2. Screen Setup: Position your screen at or above eye level to maximize alertness. Looking down at a screen can make you feel sleepier 1.
3. Bright Environment: Ensure your workspace is brightly lit. Dim lighting can reduce your alertness 1.

In summary, standing or moving more, properly positioning your screen, and ensuring adequate lighting can help reduce fatigue from prolonged online classes and screen time.
