Establish a consistent sleep schedule

Go to bed and wake up at the same time every day, including weekends. Keeping a fixed schedule within a 30-minute window trains your body's internal clock to anticipate sleep and waking, making both easier over time.

Why It Works

Your circadian rhythm is regulated by the suprachiasmatic nucleus in the hypothalamus, which synchronizes hormone release, body temperature, and alertness to a roughly 24-hour cycle. Irregular sleep timing disrupts this synchronization, leading to difficulty falling asleep and grogginess upon waking. The American Academy of Sleep Medicine recommends consistent sleep-wake times as a foundational element of sleep hygiene.

Tips

• Set an alarm for bedtime, not just wake-up, to build the habit
• If you must shift your schedule, adjust by 15-minute increments over several days
• Weekend "catch-up sleep" of more than 1 hour disrupts your rhythm for the following week
• Most adults need 7-9 hours per night; choose a bedtime that allows for this
