Daylight For Sleep: Natural Solutions For Insomnia

Light plays a crucial role in regulating our sleep patterns. Our body's internal clock, or circadian rhythm, is largely influenced by light exposure, which affects the production of melatonin, a sleep-promoting hormone. Morning daylight exposure is linked to better sleep quality at night, with people falling asleep faster and experiencing fewer disturbances.

Research suggests that bright light during the day and darkness at night are beneficial for health and longevity. Exposure to morning light can improve mental health, reduce stress and depression, enhance alertness, and promote a healthy body weight. On the other hand, excessive artificial light at night can disrupt sleep, increase the risk of obesity and cardiovascular problems, and negatively impact overall health.

To optimize sleep, it is recommended to get morning sunlight, maintain a consistent sleep schedule, make the bedroom as dark as possible, minimize electronic use at night, and avoid bright and blue light after sunset.

Morning light exposure can help reset your body's internal clock, making it easier to fall asleep at night

Our bodies have a master clock deep in our brains, as well as a series of other clocks inside our tissues that manage when hormones are released, keeping our sleep-wake cycle, hunger patterns, and other daily rhythms on a predictable cycle. Morning light exposure helps to synchronize our body clock with the 24-hour day in two critical ways:

• Specialized cells in our retinas tell our brain to stop making the sleep hormone melatonin.
• Our brain's master clock sets a sort of internal timer, instructing the body to start making melatonin again about 14 hours later.

In addition, morning light exposure can also increase the production of the stimulating hormone cortisol, getting our brains fired up for the day.

The benefits of morning light exposure are supported by numerous studies. One study found that people who let natural light into their homes during the day fell asleep 22 minutes earlier, slept more regularly, and were happier and more alert during the day than during a week when they kept the blinds closed. Another study found that office workers who were exposed to more bright morning light for five days found it easier to make decisions and scored 79% higher on cognitive tests.

To get the benefits of morning light exposure, try to get a minimum of one hour outdoors each day, including 15 to 30 minutes in the morning after daybreak. If you work indoors, sit near a window and open the shades whenever possible, or add more light to your room with table lamps that emit blue light or move your light source closer to your eyes.

Light therapy can be used to treat insomnia and circadian rhythm sleep disorders

Light therapy is particularly useful for people with insomnia and circadian rhythm sleep disorders. It can also be helpful for those with seasonal affective disorder (SAD) and those working overnight schedules. For those with insomnia, light therapy can be an effective way to improve sleep quality and energy levels. It is not a cure, but it can make it easier to fall asleep or wake up.

The science behind light therapy lies in its ability to reset the circadian rhythm, or the body's internal clock. By exposing the eyes to light similar to sunlight, light therapy helps realign the circadian rhythm with the patterns of the sun. The light affects the production of melatonin and serotonin, the chemicals responsible for regulating the sleep-wake cycle. Morning light, in particular, is key, as it stops the brain from producing the sleep hormone melatonin and sets an internal timer for the body to start producing it again about 14 hours later.

In practice, light therapy involves sitting in front of a light therapy box or visor for a set amount of time each day. The light shines into the eyes indirectly to avoid damage, and the light boxes emit strong light that mimics outdoor light without the harmful UV rays. Typically, the light box is positioned between 16 to 24 inches away from the face, with the session lasting 20 to 40 minutes at an intensity of 10,000 lux. Longer sessions and higher intensities can be beneficial.

Light therapy is generally considered safe, but some people may experience side effects such as eye strain, headaches, nausea, hyperactivity, or skin irritation. It is important to consult a doctor or sleep specialist before undergoing light therapy to ensure a safe treatment plan.

Light therapy can be used to treat Seasonal Affective Disorder (SAD) and non-seasonal depression

Light therapy is a treatment for certain health conditions that involves exposure to artificial light. During a session, the patient sits in front of a light therapy box, which emits bright light similar to natural sunlight. The light is strong but does not contain harmful UV rays. Typically, the light box is positioned between 16 to 24 inches away from the patient's face, and the session lasts 20 to 40 minutes.

Light therapy can also benefit individuals with non-seasonal depression, although the research is less conclusive. While light therapy alone can be beneficial, light therapy combined with an antidepressant tends to be more effective.

Light therapy can be done at home with a light therapy box or visor

Light therapy is a treatment for certain health conditions that involves exposure to artificial light. During a light therapy session, the individual sits in front of a light therapy box or wears a light therapy visor, both of which emit bright light similar to natural sunlight.

Light therapy boxes are designed to treat insomnia and sleep disorders, as well as skin disorders like psoriasis. Light therapy visors are typically used to treat jet lag. Light therapy boxes designed for sleep disorders filter out UV light, whereas those designed for skin disorders do not, so it is important to ensure the light therapy box emits most, if not all, UV light.

Light therapy boxes come in all shapes and sizes and can be purchased online or in stores. They may also be covered by insurance. Light therapy is generally considered very safe, but some people may experience side effects such as eye strain, headache, nausea, hyperactivity, and skin irritation.

When practising light therapy, the light source should be positioned between 16 to 24 inches away from the face. The length of the session depends on the intensity of the light. Typically, light therapy boxes with a light intensity of 10,000 lux are used, and sessions may last 20 to 40 minutes. If using a lower-intensity device, such as 2,500 lux, the session may be as long as 2 hours.

Light therapy can help reset your circadian rhythm, which is your body clock. By exposing your eyes to light similar to sunlight, light therapy helps realign your circadian rhythm with the patterns of the sun. This, in turn, can help you fall asleep earlier at night or sleep in later in the morning, depending on your needs.

Light therapy is generally considered safe, but some may experience side effects such as eye strain, headaches, and nausea

Light therapy is a safe and effective way to treat sleep issues, but some people may experience side effects. It is a type of therapy that uses exposure to artificial light to treat certain health conditions. During a light therapy session, the individual sits in front of a specialized light therapy box, which emits bright light similar to natural sunlight. While it is generally considered safe, some people may experience side effects such as eye strain, headaches, and nausea. These side effects are typically mild and tend to go away on their own after a few days. However, if they persist, it is recommended to consult a doctor, who may suggest adjustments to the light therapy regimen, such as changing the length or time of day of the sessions, or the type of light therapy product used.

It is important to note that some individuals may be more prone to experiencing side effects from light therapy. This includes people with bipolar disorder, as well as those with skin or eye conditions that make them more sensitive to sunlight. Therefore, it is advisable to consult a doctor or sleep specialist before undergoing light therapy to ensure a safe treatment plan.

Light therapy is particularly useful for individuals with insomnia, circadian rhythm sleep disorders, jet lag, seasonal affective disorder, and depression. By exposing the eyes to light similar to sunlight, light therapy helps to realign the body's internal clock with the natural patterns of the sun. This, in turn, regulates the production of melatonin and serotonin, the hormones responsible for controlling sleep-wake cycles. As a result, individuals undergoing light therapy find it easier to fall asleep earlier at night or sleep in later in the morning, depending on their needs.
