Most of us know that it is recommended to sleep 7 to 9 hours every night, but science reveals something surprising – bedtime and wake up time may be more important than sleep duration itself.

⏰ Why consistency is important
Our body functions according to an internal clock – circadian rhythm – which governs when we feel sleepy or awake.
When we go to sleep and get up at the same time every day, our biological clock remains aligned, which allows for the proper secretion of hormones such as melatonin (for sleep) and cortisol (for waking up).
➡️ Result: better concentration, more stable energy and greater resistance to stress.
ATTENTION! Too much cortisol at the wrong time is the main enemy of your sleep rhythm. If you struggle with chronic stress, consistency in sleep will not be enough.
