Light during the middle of the day has less influence on the pacemaker, but exposure to bright light such as sunlight will increase the intensity of light needed to shift the pacemaker during the sensitive periods in the morning and evening and during the night. Also, getting some bright light during the middle of the day can improve daytime alertness as well as sleep at bedtime.

In general, researchers estimate that light in the evening about 2 hours before and after usual bedtime can shift the circadian system about 2 hours later per day, whereas light in the morning about 1 hour before and after usual wake-up time can shift it about 1 hour earlier per day.

Circadian rhythm natural light -

And the proliferation of electronics with screens, as well as energy-efficient lighting, is increasing our exposure to blue wavelengths, especially after sundown. Everyone has slightly different circadian rhythms, but the average length is 24 and one-quarter hours.

The circadian rhythm of people who stay up late is slightly longer, while the rhythms of earlier birds fall short of 24 hours. Charles Czeisler of Harvard Medical School showed, in , that daylight keeps a person's internal clock aligned with the environment. Some studies suggest a link between exposure to light at night, such as working the night shift, to diabetes, heart disease, and obesity.

That's not proof that nighttime light exposure causes these conditions; nor is it clear why it could be bad for us. A Harvard study shed a little bit of light on the possible connection to diabetes and possibly obesity. The researchers put 10 people on a schedule that gradually shifted the timing of their circadian rhythms.

Their blood sugar levels increased, throwing them into a prediabetic state, and levels of leptin, a hormone that leaves people feeling full after a meal, went down. Exposure to light suppresses the secretion of melatonin, a hormone that influences circadian rhythms. Even dim light can interfere with a person's circadian rhythm and melatonin secretion.

A mere eight lux—a level of brightness exceeded by most table lamps and about twice that of a night light—has an effect, notes Stephen Lockley, a Harvard sleep researcher.

Light at night is part of the reason so many people don't get enough sleep , says Lockley, and researchers have linked short sleep to increased risk for depression, as well as diabetes and cardiovascular problems.

While light of any kind can suppress the secretion of melatonin, blue light at night does so more powerfully. Harvard researchers and their colleagues conducted an experiment comparing the effects of 6.

The blue light suppressed melatonin for about twice as long as the green light and shifted circadian rhythms by twice as much 3 hours vs.

In another study of blue light, researchers at the University of Toronto compared the melatonin levels of people exposed to bright indoor light who were wearing blue-light—blocking goggles to people exposed to regular dim light without wearing goggles.

The fact that the levels of the hormone were about the same in the two groups strengthens the hypothesis that blue light is a potent suppressor of melatonin.

It also suggests that shift workers and night owls could perhaps protect themselves if they wore eyewear that blocks blue light. Inexpensive sunglasses with orange-tinted lenses block blue light, but they also block other colors, so they're not suitable for use indoors at night. If blue light does have adverse health effects, then environmental concerns, and the quest for energy-efficient lighting, could be at odds with personal health.

Those curlicue compact fluorescent lightbulbs and LED lights are much more energy-efficient than the old-fashioned incandescent lightbulbs we grew up with. But they also tend to produce more blue light. The physics of fluorescent lights can't be changed, but coatings inside the bulbs can be so they produce a warmer, less blue light.

LED lights are more efficient than fluorescent lights, but they also produce a fair amount of light in the blue spectrum. Richard Hansler, a light researcher at John Carroll University in Cleveland, notes that ordinary incandescent lights also produce some blue light, although less than most fluorescent lightbulbs.

If something goes wrong with your circadian rhythm, it affects your sleep and can result in a sleep disorder. Getting light in the morning can help with certain sleep disorders:.

Those with delayed sleep phase syndrome or insomnia may find that using light therapy, also called phototherapy , to start the day improves their sleep patterns. Taking a melatonin supplement may also help people regulate their sleep patterns.

The hormone is naturally made by the brain and tells your body when it's time to go to sleep and time to wake up. Having trouble sleeping can have many causes. Light therapy can be helpful for some conditions that affect your sleep, but not all.

If you're having trouble sleeping, reach out to your provider to be evaluated. Research has shown that light therapy can also help people with certain medical conditions that affect their sleep, including:. The type of light you get matters as much as when you get it.

For example, artificial light inside a building does not have the same effect as unfiltered sunlight. Artificial light boxes act like sunlight. However, they are not the same. The intensity of the sun's light is , lux. A light box can produce about 10, lux or less.

A light box can cost several hundred dollars. If you're able to go outside, you can get sunlight for free. While it might be cheaper, some people don't have the chance to get real sunlight. For example, you might work at night or have to get up before sunrise. You might have to avoid the sun because of a medical condition or treatment.

You may live in a region with limited direct sunlight, particularly in winter. In these cases, a light box could be a way to get the benefits of light therapy. You'll get the most benefit from sunlight if you can get it first thing in the morning. Try to get outside in the first hour after you wake up.

Spend 30 to 45 minutes in direct sunlight. Don't wear a sun visor or sunglasses. If the light is filtered, it won't have the same effect. To get the most out of your morning light exposure, follow these guidelines:.

Sunlight is less intense first thing in the morning. It can still damage your skin , but not as much as it would later in the day. Wearing sunscreen can help keep your skin safe as you soak up the morning light.

Taking a walk first thing in the morning gets you sunlight and exercise at the same time. If you have a porch or patio, you could have your breakfast outside. Just make sure the sun is getting on you don't sit under an umbrella or awning. If the day is overcast and cloudy, you can still get sunshine.

Light from the sun that's filtered through clouds or rain can still have positive effects. Once you figure out what works, stick to a regular schedule.

Waking up at the same time every day and getting morning sunlight is a good combination. You might not be able to keep the routine all the time, but do your best to find ways to include light therapy of some kind in your day.

You can get a little bit of sun by opening the windows at home or in your car when the weather is nice.

Getting sunlight when you first wake up in the morning can help you sleep better at night. There are different ways to get more light early in the day.

Going outside in the sun is free, but you can also buy special lamps to do light therapy inside. Centers for Disease Control and Prevention. Effects of light on circadian rhythms.
