What time of day are you quick to think or act? Are you more of a morning person? Or does your brain need a few hours to get going? A lot of research suggests that we should pay attention to our body clock. It can tell us what time of day we are best able to perform, according to the Wall Street Journal.

When it comes to the human brain, many people work best later in the morning. This is because the body’s temperature takes time to rise through the day. Taking a warm shower when you wake up can help speed this up.

But everyone’s body clock is different. Morning people will rise early and work better early in the day. Evening people will wake later but their brain will work better toward the end of the day.

Research shows that we’re better at some activities at certain times of the day. Physical performance is at its best between 3 pm and 6 pm, so it’s better to exercise later in the day.

Between noon and 4 pm, people are getting tired. This is partly because we are slow to think or act after eating a big meal. Research also shows that we become sleepy around 2 pm.

Finally, it is best to eat during our active periods. This allows our body to burn calories better and stops our blood sugar levels from getting too high.
