Hormone Level, weather and Our Moods
It is cinch that Hormone Level and Our Moods may be affected by the weather. Gloomy weather can cause depression, but sunshine appears to raise the spirits. In Britain, for instance, the dull weather of winter drastically cuts down the amount of sunlight that is experienced which strongly affects some people. They become so depressed and lacking in energy that their work and social life are affected. This condition has been given the name SAD (Seasonal Affected Disorder).
The sufferers can fight back by making the most of any sunlight in winter and by spending a few hours each day under special, full-spectrum lamps. These provide more ultraviolet and blue green light than ordinary fluorescent and tungsten lights. Some Russian scientists claim that children learn better after being exposed to ultraviolet light. In warm countries, hours of work are often arranged so that workers can take a break, or even a siesta, during the hottest part of the day. Scientists are working to discover the links between the weather and human beings moods and performance.
It is generally believed that tempers grow shorter in hot, muggy weather. There is no doubt that crime against the person rise in the summer, when the weather is hotter and fall in the winter when the weather is colder. The popular research in the United States has shown a relationship between temperature and street riots. The frequency of riots rises dramatically as the weather gets warmer, hitting a peak around 27-30 degree centigrade. But is this effect really due to a mood change caused by the heat? Some scientists argue that trouble starts more often in hot weather merely because there are more people in the street when the weather is good.
The Psychologists have also studied how being cold affects performance. Researchers compared divers working in icy cold water at 5 degree centigrade with others in water at 20 degree centigrade about swimming pool temperature. The colder water made the divers worse at simple arithmetic and other mental tasks. But significantly, their performance was impaired as soon as they were put into the cold water-before their bodies had time to cool down. This suggests that the low temperature did not slow down mental functioning directly, but the feeling of cold distracted the divers from their tasks.
