One of the greatest needs for maintaining our health is sleeping. If we get good sleep, our body repairs itself, our brain rests, and the heart gets an opportunity to relax too. Many people are well aware of the fact that proper sleeping is an important need, but fewer are aware of the fact that proper sleeping in a dark environment serves as an important need.

‘Clean darkness’ means sleeping in a dark room with no artificial light from mobile phones, TVs, streetlights, or bright lights. Therefore, ‘clean darkness’ helps the body synchronize with its natural body clock and supports a healthy heart.

Learning About Body Rhythm

Our body also has a natural clock known as the “biological clock” or “circadian rhythm.” The “biological clock” regulates the time when we feel awake and the time when we feel sleepy. It also regulates crucial bodily functions, such as rate, blood pressure, and the secretion of hormones.

Such a body clock functions effectively in environments that feature a marked contrast between day and night:

Day: bright light will tell the body to be active

Night: Darkness instructs the body to sleep and repair itself

When the body is not exposed to light during sleep, it recognizes that it is time to relax. This is because the body can help relax and recover from the day’s activities.

What Is Clean Darkness?

Several strategies are referred to:

• No bright lighting in the bedroom
• Lighting effects from TV sets, laptops, or mobile phones would not be considered
• No streetlight visible through the windows
• No blinking lights from the charger and electrical appliances

Even a small amount of light will interfere with sleep. The fact is that our eyes can detect light when our eyelids are closed.

The Role of Melatonin

Darkness stimulates the production of the hormone melatonin in the body. Melatonin is also known as the “sleep hormone.” The melatonin helps with relaxation.

It is equally essential for well-being because of:

• Regulation of cardiovascular functions
• Helps to regulate blood pressure at night
• It is calming to the heart
• It protects blood vessels
• Helps in controlling the inflammation in the Body

If the bedroom is lighted, then the production of melatonin will be reduced. Reduced melatonin causes poor sleep, along with increased strain on the heart.

The role of darkness in helping the heart rest

The heart operates all day long, pumping blood throughout the body. At night, when a person is in a deep slumber, there’s a reduction in beating. There’s a reduction in blood pressure, too. This condition is referred to as nighttime dipping, and this is a healthy function in relation to the heart.

Sleeping in the dark is helpful for this process because:

• Permitting deeper sleep
• Reducing nighttime awakenings
• Normalizing the beating
• Reducing blood pressure progressively

If the environment is well-lit, there is partial alertness of the body. This ensures the heart continues working harder than it should during nighttime.

Nighttime Light Exposure and Heart Problems

Studies have revealed that excessive exposure to light at night increases the chances of cardiac issues. Those individuals who sleep with lights on or have exposure to light may experience:

• Elevated Blood Pressure
• Accelerated heart rate
• More stress hormones
• Increased risk of disease with time

Artificial lighting, especially blue light emitted by all screens, sends a signal to the brain that the day has arrived, thus preventing the heart from having proper rest.

“Clean Darkness” Promotes Improved Sleep Quality

Sleep quality involves not just the duration of the time slept, but the depth of the time slept. A clean darkness enhances the depth of the stages achieved.

Deep sleep:

• Repairs heart muscles
• Regulates hormones
• Reduces Stress
• Enhances blood circulation

People who sleep in dark environments always feel more refreshed and relaxed upon awakening. It is through this state of relaxation that the heart attains refreshed wellness.

Anybody who has experienced stress knows it can affect

Stress is another big competitor of cardiovascular health. The lack of sleep raises stress hormones, such as cortisol. Elevated cortisol levels can:

• Increase blood pressure
• Increase beat
• Damage Blood Vessels

Sleeping in a clean, dark environment reduces stress because of the calming of the nervous system. A relaxed nervous system means reduced stress.

Benefits of Clean Darkness for Overall Health

Aside from having benefits for cardiac health, sleeping in clean darkness can also do the following:

• Boost brain function and memory
• Boost the immune system
• Regulate Blood Sugar Level
• Maintain healthy body weight
• Boost mood and improve mental health

All the above advantages have the indirect effect of heart protection as they help in keeping the body in a balanced and strong position.

Easy Solutions: Creating a Dark Room

The creation of pure darkness requires less effort and money. Here are some simple steps:

• Switch off all lights before sleeping
• Avoid the use of mobile phones and TVs at least an hour before bedtime
• Use dark curtains/blinds to shade the light coming from outside
• Cover or protect small LED lights in electronic devices
• A mask may be utilized if darkness is not feasible.
• Maintain a quiet and peaceful bedroom

To achieve better sleep quality and health, minor adjustments can have a huge impact.

Healthy Sleep Practices and a Healthy Cardiovascular

Together with clean darkness, the following are also beneficial:

• Go to bed and wake up at the same time each day.
• Eating large meals late at night should be avoided. Having plenty
• Control consumption of beverages containing caffeine in the evening

Maintain a cool room temperature. “Practice relaxation before sleep, like deep breathing.” Sleeping practices, in addition to clean darkness, help to ensure a healthy heart.

Conclusion

Sleeping on a dark background is a simple and natural way to promote cardiac health. Darkness helps the body produce melatonin, reduces stress, lowers blood pressure, and allows the heart to rest as it should.

Nowadays, artificial lights are omnipresent. However, with the slightest adjustments in our sleeping context, we can safeguard our cardiac health and subsequently our overall health.

“A dark, quiet, and peaceful bedroom is not a luxury; it is a necessity for a healthy heart.” In fact, by opting to leave our bedroom light-free every night, our hearts will surely thank us because it is treated with the care that it actually deserves.
