For someone with ADHD, sitting still for an extended period of time can be extremely challenging and uncomfortable. People with ADHD often experience restlessness and a strong need for movement, which is commonly referred to as "hyperactivity." This hyperactivity can manifest as fidgeting, tapping, shifting in their seat, or feeling an overwhelming urge to get up and move around.
When they must sit still, such as during a long conversation or in a classroom or work setting, they may feel restless, antsy, and mentally agitated. The longer they have to stay seated, the more difficult it becomes to maintain focus and attention. They might find it hard to concentrate on the conversation or the task at hand, as their mind may wander and jump from one thought to another.
The struggle to sit still can also make them feel anxious or irritable. They might be constantly aware of their restlessness and may worry that they are being perceived as inattentive or disinterested, even though that's not their intention.
Sitting down for a bit to have a conversation can be particularly challenging if it is in a setting without much external stimulation. In more active environments, like during a walk or while engaging in an interactive activity, they might find it easier to stay engaged in the conversation because the physical movement helps them regulate their attention.
It's important to understand that these experiences can vary depending on the individual and the severity of their ADHD symptoms. Some people with ADHD may develop coping strategies over time that help them manage restlessness and maintain focus, while others may find it consistently difficult to sit still for extended periods. In any case, it can be beneficial to create an environment that allows for movement or breaks to accommodate the needs of someone with ADHD during lengthy conversations or activities that require prolonged sitting.
