What time to go to bed? Practical tips for a refreshing morning

Understanding sleep cycles

When to go to bed? Follow your sleep cycles. Human sleep occurs in repeating cycles lasting approximately 90 minutes. Each cycle includes several phases, from light sleep to deep sleep and REM phase, where the most vivid dreams occur. For a fresh awakening, it is ideal to wake up at the end of a complete cycle, not in the middle of deep sleep. If you wake up at the wrong time in the cycle, you may feel groggy and disoriented, even after eight hours of sleep. Conversely, waking up after five cycles (7.5 hours) can be more refreshing than after seven incomplete cycles.

Calculating the ideal bedtime

To determine the optimal bedtime, first set the time you need to wake up. Then count back 7.5 or 9 hours (five or six complete sleep cycles). Add 15-30 minutes for actually falling asleep. For example, if you wake up at 7:00, you should aim to fall asleep around 22:30 (for 8.5 hours including the time to fall asleep) or around 23:30 (for 7.5 hours). This system works better than a fixed eight-hour norm as it respects your body’s natural rhythms. Also, feel free to check out our article “How long to sleep.”

The impact of circadian rhythms

Your body controls internal biological clocks that regulate hormone production and body temperature according to daylight. Melatonin, the sleep hormone, naturally begins to be secreted around 21:00-22:00 in the evening. Going to bed in line with these natural signals significantly enhances sleep quality.

Exposure to bright light in the evening, especially blue light from electronic devices, can disrupt this production and shift your sleep rhythm. Therefore, it is important to dim lighting and limit phone and tablet use at least an hour before bedtime.

Individual sleep needs

While the average recommended sleep duration is 7-9 hours for adults, individual needs can vary. Some people are naturally early risers (chronotype "lark"), who function best with early bedtimes and wakefulness. Others are evening types ("owls"), who are energized later in the day and naturally go to bed later. Knowing your chronotype can help you find the optimal sleep schedule. Larks should utilize their morning energy and go to bed around 22:00-23:00. Owls may perform better with sleep onset around 23:30-00:30, if life circumstances allow.

Practical strategies for better sleep

Establishing a consistent evening routine signals your body that it's time to rest. This can include a warm shower, reading a book, gentle stretching, or meditation. It’s important to stick to the same sleep time even on weekends to prevent disrupting your circadian rhythm. The sleeping environment should be cool, ideally around 18-20°C, dark, and quiet. Investing in quality blackout curtains or a sleep mask can be worthwhile. Also, avoid caffeine after 14:00 and heavy meals before bedtime, as they can disrupt sleep quality.

Morning routine for energetic wakefulness

The way you wake up in the morning influences your entire day. Instead of a harsh alarm, try using a dawn simulator or natural light. Immediately after waking, drink a glass of water to replenish fluids lost overnight. Brief morning exercise or at least some stretching can help kick-start circulation and increase alertness. Exposure to natural light within the first 30 minutes after waking also helps synchronize your biological clocks and improve nighttime sleep onset.

When to seek professional help

If you still feel fatigued even when following good sleep habits, you may have a sleep disorder such as sleep apnea or restless legs syndrome. Chronic insomnia may also relate to stress, anxiety, or other health issues. Don’t hesitate to seek medical help if sleep problems persist for more than a month and affect your daily life. Proper diagnosis and treatment can significantly improve your sleep quality and overall well-being.

The mattress also makes a big difference

Even respecting sleep cycles and listening to your biology won’t help if you have a bad mattress. Therefore, ensure that your mattress provides adequate body support and allows for quick settling into a comfortable sleeping position. If not, don’t hesitate to browse our Purtex mattresses, where you can easily find the ideal choice for perfect sleep.
