Light seems to have therapeutic antidepressant effects when an organism is exposed to it at appropriate times during the circadian rhythm, regulating the sleep-wake cycle. [6] [4] In addition to mood, learning and memory become impaired when the circadian system shifts due to light stimuli, [6] [20] which can be seen in studies modeling jet lag ...
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
Mood issue #3: Not getting enough sleep. A poor night’s sleep can make you feel cranky the next day. But chronic sleep problems can also lead to cognitive problems over time, according to the ...
The sleep cycle is an oscillation between the slow-wave and REM (paradoxical) phases of sleep. It is sometimes called the ultradian sleep cycle, sleep–dream cycle, or REM-NREM cycle, to distinguish it from the circadian alternation between sleep and wakefulness. In humans, this cycle takes 70 to 110 minutes (90 ± 20 minutes). [1]
Jessica P., a Gen Xer, shares her struggles with waking up throughout the night: “While I consistently wake up at 7 am to start my day, I never really sleep through the night without waking up ...
The temperature was already above 80 degrees and rising. The work of maintaining the public water supply in a heat wave is crucial. But it needs to be done as safely as possible. That means ...
Exposing skin to the ultraviolet radiation in sunlight has both positive and negative health effects. On the positive side, exposure allows for the synthesis of vitamin D 3. Vitamin D has been suggested as having a wide range of positive health effects, which include strengthening bones [1] and possibly inhibiting the growth of some cancers.
Key Takeaways: Itchy ears are not uncommon when adjusting to hearing aids, as it takes time for the ear to adjust to the presence of a hearing aid. Other common causes of itchy ears includes ...
