This is usually the ideal time to wake up. Your body stops producing melatonin, a signal that it’s time to get active and start the day. However, this a poor time to exercise since your blood pressure is often at its highest.
Between these hours you are at your most alert. Your body is producing the highest amounts of cortisol, giving your brain a boost. Your short-term memory is at its peak and you are at your most productive.
This is when most of us eat our lunch. The subsequent increase in digestive activity can lead to a drop in alertness and the familiar urge for a daytime nap. Drinking alcohol at this time can make you especially drowsy.
Your core body temperature is beginning to fall and melatonin production increases, signaling to the body that it will soon be time to sleep. For most of us, this is the ideal time for bed. Interestingly, this may also be your most creative period of the day.
Your brain is busy clearing out toxins and consolidating memories. Melatonin production is hitting its peak. If you are still awake, your attention levels will be extremely low.
Melatonin levels begin to fall and your core body temperature reaches its lowest level. This is when you are likely to be in the deepest stages of sleep.
Although these stages of the sleep/wake cycle are typical, we are all different. If you're a 'morning person', you're likely to be at your most productive early in the day. If you're an 'evening person', you'll typically wake later and hit your most productive stage later in the day, too.
