Feeling inactive, sleepy and lethargic after lunchtime is a common thing. The activity levels of our body basically depend on our lifestyle and also on our body clock or circadian rhythm which is controlled by the Suprachiasmatic Nucleus in our brain by releasing the hormone melatonin which makes us feel sleepy in afternoon.

• A person feels sluggish depending on the circadian rhythm cycle which is basically a 12-hour cycle or 24 hours also depending upon one’s body aspects.
• Other factors contributing to an inactive body and fatigue can be the type of food we consume at lunch or any other meal. A person needs to be hydrated and should have a balanced meal including a proper ratio of essential nutrients.
• Getting eight hours of sleep throughout a day also plays an important role.
