How does "winter time" affect your health?
health| 21 October, 2024 - 11:41 PM
Many countries around the world will start working on winter time in a few days, where the clock will be set back by one hour.
Experts have pointed out that this affects people's health and behavior, sometimes without them knowing it.
According to what experts told the British newspaper The Independent, the health and behavioral problems associated with winter time result from its disruption of the body's biological clock, which regulates the sleep-wake cycle.
This disorder causes increased feelings of fatigue and exhaustion. Disturbed sleep can also increase the risk of cardiovascular disease.
In a 2019 study by researchers at Harvard Medical School and Massachusetts General Hospital, the effect of sleep disturbances on heart disease in mice was examined.
The study found that after 16 weeks, mice whose sleep cycles were somewhat disrupted developed more fatty deposits (plaques) in their arteries than mice with normal sleep patterns.
Sleep-deprived mice also had lower levels of white blood cells in their bloodstream, and lower amounts of hypocretin, a hormone that plays a key role in regulating sleep and wakefulness.
Research has also shown an increase in car accidents when the time changes to winter as drivers try to adjust to the time change.
The increased hours of darkness can lead to low mood and depression in some people, as well as fatigue, muscle pain and weak bones due to a lack of vitamin D, which the body gets from exposure to sunlight.
Some people also suffer from seasonal affective disorder (SAD) as a result of the shorter days, according to the NHS.
Symptoms of seasonal affective disorder include persistent low mood, loss of interest in normal daily activities, feelings of hopelessness or guilt, and sleeping longer than usual.
The NHS says a lack of sunlight can prevent a part of the brain called the hypothalamus from working properly, which can affect the production of melatonin (the sleep hormone) and serotonin (the mood hormone).
