So, that late evening surge in focus, a good thing or not?
As mentioned, it’s of cortisol kicking in. When fuel timing and fuel type lacks nutritional status — especially low protein intake or sugary foods earlier in the day — the body compensates by raising stress hormones and liberating sugar stores.
What do these hormones do?
• Increase alertness
• Mobilise stored glucose
• Suppress fatigue signals
They also:
• Delay melatonin, the sleep hormone
• Reduces deep sleep
• Impair release of growth hormone
• Compromises recovery
When exercising or training for example, these stress hormones play an important role. Recovery is compromised however if these hormones remain high as we move towards out natural sleep phase.
A “second wind” may therefore be your stress hormones responding to your daily nutritional intake and activity levels
Question:
Do late daily surges in energy make you feel focused and controlled — or wired and slightly restless?
