Beware getting too stressed in the evening

Stress is associated with a number of ill-health effects. However, time that stress occurs during a 24-hour cycle appears to exert different effects and this has implications for longer-term health, with stress occurring at night being more dangerous.

Heart surgery? Slate it for the afternoon, study says

Paris - The risk of serious heart problems after open heart surgery nearly doubles when the operation is performed in the morning rather than the afternoon, researchers said Friday.

Circadian clocks influence body’s response to diet

Scientists from Baylor College of Medicine have found that alterations to the circadian clock affect how the body responds to diet. In turn this influences microbes residing in the digestive tract.

Temperature throws the body clock back and forth by one hour

New York - The internal body clock is finely tuned and disruptions are associated with a range of diseases, such as obesity, diabetes and heart disease (which is a concern for shift workers). Changes to temperature can also disrupt the fine balance.

Bring the sun into your home with the Silk smart lightbulb

A new smart LED lightbulb aims to improve your health, wellness and sleep patterns by providing you with light that is more akin to that of the sun. It slowly shifts from blue to red in the day, allowing your body's circadian rhythm to operate normally.

Researchers find shift work triggers obesity and ill-health

London - New research has found that there are higher rates of obesity and ill-health in shift workers when compared with the general population.

Nightshift work affects the immune system

Dallas - The body clock can go out of sync when a person works the night shift. Such disruptions evidently cause extreme tiredness, but a new study suggests that this can also lead to immune system disorders.

Light activates brain even in blind people

Montreal - Pay attention when your spouse tells you to turn off the bedside lamp. He or she may not be able to sleep because the light is keeping the brain awake.

Hamsters have in-built seasonal clocks

As well as circadian rhythms (natural body cycles), many animals are thought to have seasonal clocks (including, perhaps, people). A new study has shown that such internal ‘calendars’ function in hamsters.

Tidal rhythms of sea creatures

Some marine creatures have internal rhythms that cycle with the tides, influenced by the moon. These cycles are independent of circadian rhythms.

Do electric lights affect our body clocks?

A new study into the effect of light suggests that the body's internal clock (or circadian rhythms) become skewed when they are exposed to electric lights. However, the mechanism reverts back to schedule when people pursue outdoor activities.

Sleep, circadian rhythms and aging

Human sleeping and waking patterns are linked to the internal circadian clock that corresponds closely with the 24-hour cycle of light and darkness. New studies show that when the disruptions can lead to aging.

Severe depression linked to the body's clock

Michigan - New research suggests that patients with major depressive disorder appear to have a malfunctioning 'body clock'. This finding could lead to new types of treatment.

Does light or temperature affect the body clock?

Studies undertaken on fruit flies have shown how their body clocks are affected by changes in temperature. Fruit flies are often used to mimic studies in humans. The findings have implications for conditions like jet-lag.

Christmas indulgence can affect the ‘food clock’

San Francisco - Feeling a little tired and off-color after the Christmas excesses? One of the reasons may not be the simply the copious amounts of food and alcohol but rather the disruption to the body’s internal ‘food clock’.

Do plants have 'body clocks'? Why plants bloom in the spring

Edinburgh - Some recent scientific research suggests that, like people, plants have daily and seasonal rhythms. The results of the research, into a protein contained within many plants, could possibly lead to improvements for agricultural production.
