What might cause sudden tiredness in the mid-afternoon?

Sudden tiredness in the mid-afternoon is a common experience for many people. This can be caused by several factors:

1. Sleep Quality: Poor sleep at night can lead to feeling sleepy during the day. If you do not get enough rest, your body might feel tired in the afternoon.

2. Medications: Some medications, like those used for attention issues, can affect sleep patterns and lead to daytime sleepiness. It's important to talk to a doctor if you think your medicine might be causing tiredness.

3. Health Conditions: Certain health issues, such as heart problems, can make you feel more tired during the day. If tiredness is affecting your daily life, it might be good to see a healthcare provider.

Daytime sleepiness can also be a sign of other underlying issues, so it's important to pay attention to how often it happens and if it's affecting your daily activities.
