In almost all of the U.S. and other parts of the world, the end of Daylight Saving Time falls on Sunday, Nov. 7 this year.
For most, setting the clock back an hour 鈥� or 鈥渇alling back鈥� 鈥� is the full extent of adjustment needed. But for some, especially those who experience sleep difficulties, health issues or mood disorders, adapting to longer periods of darkness can be a challenge.
Although an hour doesn鈥檛 sound like a lot, when compounded with the seasonal reduction in sunlight, it can contribute to feeling more tired, unfocused and even depressed.

Vitamin D is commonly found in foods, such as oily fish, fish liver oil and egg yolks. You can also take daily supplements (400-800 IU daily is the recommended dose), if getting outside isn’t an option.
If you are feeling more tired, moody or unfocused during the day, consider taking extra breaks outside to help your body naturally produce vitamin D and remind your brain it鈥檚 a good time to stay awake.
