How Light Affects Sleep?

Sleeping with the light on can impair a person's body clock. Research has shown that the body clock is negatively affected even if the person continues to doze off. The research into the effect of light on sleep can help foster new treatments for various sleep disorders.

Being exposed to light at nighttime can trigger a chemical process that can operate as a neural switch that can switch the sleep/wake cycle on and off. By nature, the sleep/wake cycle is run by the pineal gland. The pineal gland, located in the brain, secretes melatonin. The production of melatonin is at its peak when a person sleeps.

An enzyme called AA-NAT or N-acetyltransferase is involved in the production of melatonin. This particular biochemical machine can cause the production of melatonin to turn on and off. High levels of the AA-NAT enzyme can produce high levels of melatonin to induce sleep. In general, the pineal gland shields the AA-NAT enzyme from being destroyed by proteasomes or barrel-shaped cell structures.

Turning on a bedside lamp at nighttime can block the stimulation of the pineal gland causing the AA-NAT protein to be destroyed by the proteasomes. This results in a continuous drop in the level of melatonin secretion. Exposure to light can help control the production of melatonin.

	Random Sleeping Tip
Another very common cause that makes people get up several times at night is that they drink a lot of water before going to bed. Therefore it is important that you do not drink fluids before going to bed so that you are able to avoid getting up several times at night. It is best that you take fluids about 2 to 3 hours before going to bed.

Melatonin is linked directly to the sleep/wake clock of the mind. Light therapy can be used to effectively regulate the levels of melatonin secreted by the pineal gland. This type of treatment can be used for treating sleeping conditions like insomnia or jet lag.

Light Benefits Sleep

Getting the right amount of sleep daily can help keep the body's health at its peak. Unfortunately outside factors can easily disturb the body's natural body clock and cause it to miss out on some much-needed sleep. Most people are not aware of the fact that using incandescent light bulbs can cause disruptions in a person's sleeping cycle. Continuous exposure to incandescent light bulbs can cause a person to feel that their days are longer.

Incandescent lighting and even fluorescent lighting can deprive the body of the natural sunlight it needs. Regardless of warnings on the subject of contact with direct sunlight the body needs at least an hour of natural sunlight a day to stay healthy.

Lighting Products for Better Sleep

Fortunately, people can now purchase lighting products that mimic the effect of the sun's natural light on the body. Full-spectrum lighting products are a great way to inject some light into the body without worrying about skin cancer. Full spectrum lighting can help bring about a healthy night's sleep.

Machines like the full-spectrum lights and sun alarms can help regulate a person's sleeping cycle. Research has shown that exposure to varying degrees of light can trigger the body to turn out hormones that will cause a person to feel sleepy or wake up. A sun alarm can be used to awaken a person from sleep by imitating first light at dawn. The eyes are highly sensitive to any amount of light particularly in the morning after a night of sleep.

The light emitted by a sun alarm sends a signal to the brain that in turn causes the pineal gland to secrete serotonin. This hormone causes the body's natural instinct to wake up at the sight of light. In contrast, the pineal gland also secretes the hormone called melatonin. These hormones cause the body to feel sleepy due to the lack of sunlight exposure.

A sun alarm is also a better alternative to the traditional objects used to wake up a person from sleep. In most cases, people use loud alarm clocks that buzz or ring incessantly without successfully waking up the person. The noise generated by the alarm clock simply adds to the stress that an individual faces daily.

A sun alarm is a gentle way to wake up each day without the clatter of an alarm clock. It works in accordance with the body's natural instinct to get up with the sunlight. Too much noise in the morning can easily jolt the body's mechanisms causing it to be strained throughout the day.

The sun alarm can also be used to simulate sunsets. This is a great way to fall asleep as the body is slowly lulled into the night as opposed to tossing and turning in bed.
