One of the key benefits of moving to summer clock is improving sleep quality. Increased exposure to light hours helps regulate the body’s biological clock, and especially the secretion of melatonin hormone. This hormone, which is secreted from the brain gland in the brain, is responsible for regulating sleep and caution. In the winter clock, the early darkness sometimes causes disruptions on the biological clock, which can lead to early fatigue and difficulty getting up in the morning. The transition to a summer clock, therefore, allows the body to adapt to a new and healthier routine.
At the same time, increased light hours positively affect mood. Sunlight increases the secretion of crateonine hormone, which is directly related to a good feeling, calm and feeling of happiness. According to studies, the winter clock has an increase in seasonal depression, especially in countries where dark hours are longer, such as Scandinavian countries. There is also special light treatment for depression. In Israel, the extra light hours of the summer watch significantly help improve the overall mood.
Another important benefit of the summer watch is related to vitamin D, which is created in the body in response to the sun’s radiation. This vitamin is important in maintaining bone and teeth, as it helps to absorb calcium and phosphorus. Many studies have indicated that vitamin D’s normal levels contribute to reducing the risk of bone fractures, especially among seniors, improving muscle function, and reducing the risk of diseases such as intestinal cancer and prostate cancer. In Israel, despite the multiple sun, it is found that a penalty from the population suffers from vitamin D deficiency, so additional light hours may greatly help reduce the shortage.
Beyond the direct health aspects, the summer watch also contributes to road safety. Many more light hours significantly reduce the risk of road accidents. U.S. data shows that the driver of a summer watch may prevent hundreds of fatal accidents every year, with darkness up to two times the risk of deadly pedestrian and cyclists. In Israel, the longer light hours will also allow people who come back late to work safely.
A study at the University of Edinburgh also pointed to another important benefit: blood pressure reduction. It has been found that exposure to UV radiation from the sun for about an hour leads to a significant decrease in blood pressure, probably due to the release of nitrogen (NO) skin. Thus, more light hours may contribute to the reduction of blood pressure in the public.
However, alongside the many benefits, the transition to the summer watch is not devoid of disadvantages. Studies indicate that in the first few weeks there is an increase in heart attacks. A 2008 study showed a 10% increase in the prevalence of heart attacks in the early days of transition, probably due to the rapid change in sleep and prevailing patterns, which leads to the balancing of the body. In addition, sometimes the summer watch actually causes a prevalence, as the biological clock affected by sunlight exposure is difficult to adapt to the rapid changes in light conditions and darkness.
In addition, despite the health benefits of sunlight, increased exposure to ultraviolet radiation (UV) may increase the risk of melanoma skin cancer. This radiation can also harm the eyes, so it is important to maintain precautions when exposure to the sun, especially from 10am to 4pm. It is recommended to use high sunscreen (SPF), as well as in sunglasses that filter the UV radiation.
