Both sunlight and artificial light have a significant influence on your sleep. Exposure to light helps us wake up. The light of the rising sun stimulates our mind and body. Light encourages feelings of alertness, energy, and wakefulness. If you are trying to go to sleep, light exposure may negatively impact your rest because it stimulates alertness. Staying alert as can pose a severe problem and keep you from healthy and refreshing sleep. Light exposure at bedtime can make it harder for you to fall asleep. Trying to sleep in an environment that is insufficiently dark can lead to frequent and prolonged awakenings.

Is it better to sleep in the dark?

Light and dark are critical signals for your “sleep clock.” Historically, the fluctuations in light across the solar day set our internal clock or circadian clock. Technological advances such as electricity and artificial light have forever changed our patterns of exposure to light. So it’s no surprise that artificial light in your sleep environment can negatively impact your sleep.

Why is blocking light so important for sleep?

Darkness is critical for sleep. The absence of light signals your body that it’s time to sleep. Light exposure at the wrong time can change your internal clock, which regulates sleep. Your body relies on this biological mechanism for falling asleep, staying asleep, and waking. Light can and will interfere with your “sleep clock.” Light at the wrong times will interfere with not only the quantity of your sleep but also the quantity too.

Nighttime light can be harmful to your health.

Research shows that nighttime light exposure can be harmful to your health. According to recent research, some light sources in the spectrum at night suppresses the production of melatonin. We understand that even dim light can disturb our sleep or circadian rhythm.

Can night lights disrupt sleep?

Melatonin, a structurally simple hormone, has some effect on your sleep. The pineal gland or epiphysis synthesizes and secretes melatonin.  It is a critical hormone for sleep because it signals your brain when it’s time to rest. Melatonin transmits critical information about environmental lighting to various parts of your body. It can affect biological rhythms such as your circadian rhythms or the sleep-wake cycle.

Melatonin signals help initiate your body’s physiological preparations for sleep. Feelings of drowsiness increase, your muscles start to relax, and your body temperature drops. As darkness falls during the early evening, melatonin levels naturally rise.   Melatonin levels continue to rise throughout most of the night, before peaking at around 3 a.m. Melatonin levels continue to fall during the early morning and remain low for most of the day. Evening light exposure delays the onset of the body’s transition to sleep and sleep itself because it inhibits the naturally timed rise of melatonin in your body.

What is the right amount of light for sleep?

Managing light exposure in your home, especially in your bedroom, is critical to creating a healthy sleep environment. With careful attention and a little bit of planning, you can create a bedroom that guards against unwanted light. Limiting light at night is important to protect the quality of your sleep.

Simple solutions such as shades and curtains on windows will work well to keep outside light from disturbing your sleep. Use window coverings that are heavy enough to completely block light. Correctly fitted window coverings can block slivers of a streetlight or the early morning sunlight from filtering in. Even brief exposure to light can disturb your sleep. Blackout curtains are installed in homes to provide this kind of thorough protection against unwanted light.
