Surround yourself with warmth by adding sunlight and cheerful colors to your routine. For 5 days, go for a 10-minute walk in the bright sun in the early afternoon. If it is cloudy or windy, forego the walk, but light a candle and spend a few minutes watching the flame. Routine is particularly good for your body type, so try to schedule this sunlight walk or candle at the same time each day. A daily walk and lots of sunshine will help you to avoid over-stimulation and mental strain.
