What Causes Tiredness After Sitting For A While?

Hello,

I cant figure out why i get so tired around 3pm each day. I work out 5 days a week (cardio and weights), eat plenty of fruit & Veg and lean meats. I get 8 hours sleep per night. So as far as i can see im doing everything right. I do have an office job in which i sit down for 9 hours a day, but i consider myself very fit. I get so tired around 3pm i have micro sleeps at the computer. Is there something i can try?

Hi,
Thanks for asking.
Based on your query, my opinion is as follows.
1. Body can work for long, but the mind requires rest. A reboot or small nap is necessary or a break, which you are possibly feeling is normal.
2. Increased protein diet and dehydration are usual causes of tiredness.
3. Increase your fluid intake. Reduce protein during afternoon. This could help you. However, a break from work to rest the mind is necessary after long work duration to reboot yourself.
Hope it helps.
Any further queries, happy to help again.
