The link between nightlight and cardiovascular health
According to Dr. Basavaraj S Kumbar, an internist at Aster Whitefield Hospital, exposure to light at night reduces the production of melatonin, an important hormone for deep sleep, while increasing cortisol, the stress hormone. This imbalance affects the body's circadian rhythm, affecting the regulation of glucose and blood pressure, thereby increasing the risk of cardiovascular diseases.
Studies published in the JAMA Network and the journal Sleep Health also show that exposure to light at night is associated with atherosclerosis, high blood pressure, obesity and diabetes.
What does sleeping in a darkroom help with?
Dr. Basavaraj S Kumbar says that sleeping in completely dark conditions plays an important role in maintaining the body's natural circadian rhythm. When the surrounding environment is completely turned off, the body receives a clear signal that it is time to rest, thereby helping to promote deeper and better sleep. Deep sleep not only helps the body recover energy, but also plays an essential role in balancing metabolism, regulating hormones and supporting the immune system to function effectively.
In addition, sleeping in the dark also has important benefits for the cardiovascular system. When not bothered by light, the heart and arteries have a real chance to rest, reduce pressure and recover after a long day of activity. This helps maintain a stable heart rate, reduces the risk of high blood pressure, and contributes to protecting long-term cardiovascular health. Thus, simply turning off the lights while sleeping can also have profound positive effects on the body, from improving sleep quality to improving overall health.
Tips for getting quality sleep in the darkroom
Party, cool and quiet: Use a morning curtain or sleep mask, keeping the room temperature comfortable.
Avoid electronic devices before bed: Do not use phones or computers at least 60 minutes before bed to avoid disrupting melatonin production.
Maintain a regular sleep routine: Plan regular bed and wake times to stabilize your body clock.
Limit caffeine and heavy foods before bed: Avoid causing difficulty falling asleep and sleep disruption.
Relax before bed: Take a deep breath, meditate or read a book in a quiet light to help the body prepare for sleep.
Use light red light: If you need light, very light red light that is very blurred will have little effect on melatonin.
Remove hidden light: Turn off or cover light sources such as alarm clock, flashlight, tuyenals.
