We often treat sleep as an inconvenience—something to minimize so we can work more. This is a fatal error. Sleep is not the absence of productivity; it is the fuel for it. Without adequate rest, your cognitive function, emotional regulation, and decision-making skills plummet. Good sleep hygiene is the foundation of a high-performance life.
Sleep hygiene refers to the habits and environment that promote consistent, quality sleep. It starts with light. Your body’s internal clock (circadian rhythm) is regulated by light exposure. Get bright sunlight in the morning to wake up, and dim the lights in the evening to trigger melatonin production. Avoid blue light (phones, laptops) for at least an hour before bed.
Temperature plays a huge role. Your body needs to cool down to enter deep sleep. Keep your bedroom cool—around 65°F (18°C) is optimal for most people.
Consistency is king. Going to bed and waking up at the same time every day—even on weekends—trains your body to fall asleep faster.
Finally, create a wind-down ritual. This could be reading fiction, stretching, or taking a warm shower. This signals to your brain that the workday is over. If you sacrifice sleep for work, you will eventually end up with neither. Prioritize your rest, and your focus will take care of itself.
