These tips can help:
Boost your vitamin D levels - With less time in the daylight, we need to get more vitamin D by eating foods like wild salmon, eggs, dairy, and mushrooms. Vitamin D can affect our moods, and it can be hard to get enough from diet alone, so you may want to consider taking a supplement to make sure you’re getting enough.
Load up on foods with tryptophan - Spending less time in the sun could also affect brain chemicals including serotonin and melatonin, which regulate mood, sleep, and appetite. But eating foods high in tryptophan, including poultry, eggs, bananas, and oats, can help give a boost.
Stick to your normal bedtime - After we set the clocks back an hour, your brain still thinks it’s an hour later than it really is, so you’ll feel tired earlier in the evening. But hang in there until you normally go to sleep so you help your body adapt to the new schedule.
