Please close the blinds before going to bed, draw the curtains, and turn off all the lights. A new study from Northwestern University School of Medicine reports that compared to sleeping in a dimly lit room at night, sleeping in a moderate-intensity light environment impairs cardiovascular function and leads to insulin resistance levels the next morning. Elevated, thereby increasing a person's risk of heart disease and diabetes.

Study results show that just one night of exposure to certain room lighting during sleep can impair blood sugar and cardiovascular regulation, which are risk factors for heart disease, diabetes and metabolic syndrome. Therefore, it is important for people to avoid or minimize light exposure during sleep.

Sympathetic nervous system and Parasympathetic nervous system regulate human physiological functions during the day and night respectively. There is already evidence that exposure to sunlight during the day increases heart rate by activating the sympathetic nervous system, which gets the heart racing and increases alertness to cope with the day's challenges. The results of this study suggest that similar effects occur when exposed to light during nighttime sleep.

Research has found that when sleeping in a room with moderate lighting, your heart rate increases. Even if a person falls asleep, the autonomic nervous system is activated, so the body cannot rest normally.

Researchers suggest that during sleep at night, do not turn on the lights if it is safe to do so. At the same time, the color of the light is important. Amber or orange-red light has less stimulating effect on the brain; do not use white or blue light. If you cannot control outdoor light sources, you may choose to wear a shade or eye mask or move the bed to avoid light.

How to judge whether your room is too bright? "If you can see clearly, the room is probably too bright," the researchers said.
