2. Watch a Christmas comedy
Tuning into a broadcast of It’s a Wonderful Life is great Christmas tradition, but you might want to try another festive film to help you sleep. Researchers at the University of California at Irvine conducted a study with 16 people, whom they got to watch a funny videotape. The researchers measured various biochemicals related to stress and found the participants’ stress hormone levels dropped significantly watching the comedy, and levels of the anti-stress growth hormone rose 87 percent. Take a load off, watch a funny Christmas classic—such as Elf, A Christmas Story, and Scrooged—and you’ll be relaxed for bed.
