Do you notice feeling a little bit more down in the autumn/winter time as the nights get longer and days get shorter? Well, You are not alone. Lots of people feel the effects of seasonal affective disorder or SAD. And there is real science which explains why you might be feeling the way you do. 1. our serotonin levels drop as daylight hours shorten this can make us feel a little less happy and less relaxed. 2. Our vitamin D levels are often low in the winter time as there isn’t as much sunlight and vitamin di is needed to help with serotonin levels which make us happier 3. Melatonin is another brain chemical that is produced in darkness hours and is designed to help us become sleepy, but as there are more darkness hours in the winter time you can over produce melatonin which can make you sleepy in the daytime too Watch the clip for my top tips on how to combat seasonal affective disorder. #sad #seasonalaffectivedisorder #winterblues #medical
