Sleep is vital to our wellbeing. Many of us have problematic sleep schedules due to poor sleep habits. These habits damage mental and physical health over time. Knowing how we're affecting our sleep can help us fix these habits and reset our sleep routine.

1. Inconsistent Bedtimes

We often underestimate the power of our body's internal clock, the circadian rhythm. This built-in timer helps regulate when we feel awake and sleepy. A significant factor that ensures its proper function is consistency. We disrupt this rhythm when we waver from a regular sleeping pattern by going to bed at inconsistent times.

Imagine driving a car and continuously shifting gears without rhyme or reason. The car's performance would falter, and so does our body's performance when we change our sleep times unpredictably. Sleeping at different times each night is akin to subjecting your body to perpetual jet lag. The consequences of this can range from mood swings and irritability to a long-term bad sleep schedule that's hard to shake off.

The remedy is simple in theory but may require discipline in practice. Establishing a consistent sleep routine can significantly improve sleep quality and overall health. Pick a bedtime and wake-up time that suits your lifestyle and stick to it, even during weekends. This regularity can help you reset a bad sleep schedule. Over time, your body will adapt, making it easier to fall asleep and wake up naturally without the groggy feeling that irregular sleep often brings.

2. Exposure to Blue Light

In today's digital age, screens are ubiquitous in our lives. While they offer countless benefits, they come with a hidden cost: the emission of blue light. This particular light spectrum has a short wavelength and high energy, and research suggests that prolonged exposure, especially in the evening, can suppress the secretion of melatonin, our sleep hormone.

When melatonin production is hindered, our body finds it challenging to recognize that it's time to wind down and sleep. The effects can include trouble sleeping, reduced REM sleep, and feeling less refreshed.

Luckily, there are various blue light remedies. Limit nighttime screen time, especially an hour before bed. If you must use your devices, explore settings or apps that reduce blue light emissions, often termed 'night mode' or 'warm mode.' Another practical solution is to invest in blue-light-blocking glasses designed to filter out the harmful spectrum of light.

3. Excessive Caffeine Intake

The morning ritual of sipping a cup of coffee is relished by many. It provides a much-needed morning boost. However, caffeine's stimulant benefits have a price. Half of the caffeine in your system can remain active for 3 to 5 hours after consumption. This can prevent the onset of sleep and reduce the quality of deep sleep, leading to potential bad sleep schedule effects.

The key is moderation and timing. If you want to reset your sleep routine, you must watch your caffeine intake. Avoid coffee after 2 p.m. to give your body time to process it before night. Opt for decaffeinated alternatives or herbal teas if you crave a warm beverage in the evening.

4. Lack of Physical Activity

Our bodies are designed to move. Physical activity ensures overall health and plays a pivotal role in regulating our sleep. Regular exercise increases brain serotonin and decreases cortisol, which improves sleep quality and duration. Sedentary lifestyles can cause insomnia, frequent wake-ups, and poor sleep schedules. When we try to relax at night, residual energy can cause restlessness.

The beauty of physical activity is that it doesn't always mean rigorous workouts or hours at the gym. Simple, consistent activities can make a world of difference. This can include a daily 30-minute walk, stretching exercises, or even light house chores. Over time, these activities can signal your body that it's time to rest, promoting better sleep at night.

5. Poor Sleeping Environment

Your bedroom serves as the sanctuary where sleep should come quickly. However, various factors within this environment can directly disrupt your ability to drift off peacefully. Whether it's the hum of street noise, the glare of streetlights, or an uncomfortable temperature, these seemingly minor annoyances can accumulate and directly lead to a bad sleep schedule.

To promote optimal sleep quality, it's crucial to curate a sleep-friendly environment tailored to your personal needs. Consider investing in blackout curtains or shades to eliminate intrusive light. If noise is a concern, earplugs or white noise machines can mask disruptive sounds, creating a consistent auditory environment. Regulate the room temperature; many experts suggest a cooler room, around 60-67°F (15-19°C), can enhance sleep quality. The overarching aim should be to create a room that feels like a relaxation haven that signals to your body that it's time to wind down.

6. Lack of Morning Sunlight

Blue light can keep you awake and aware all day, contrary to conventional opinion. UV rays from the sun are more stronger than blue light; thus, exposing yourself to bright light shortly after waking up helps set your circadian rhythm and maintain a healthy sleep routine.

Lack of sunshine reduces your body's ability to produce vitamin D, which impacts your immune system, emotions, bone health, and hormone production.

7. Nightcaps

Liquor is a depressant, so relaxing or sleeping may seem like a good idea. Alcohol reduces sleep quality, especially REM sleep, crucial to nighttime rest. Alcohol can be pleasurable in moderation as part of a healthy lifestyle, but do so carefully. There is no scientific evidence that alcohol aids sleep.

8. Daytime Naps That Last For Hours

A midday nap boosts energy, healing, productivity, and memory. However, a protracted slumber may make it hard to wake up and leave you weary. Additionally, it may make it harder to sleep at your usual hour. A snooze of 30-45 minutes is just about perfect.
