Why it works:
Evolutionary psychologists believe that we see flowers and plants as a subconscious cue of safety ("Things can grow here—let's set down roots"), reward ("All that foraging paid off") and promise ("These buds mean that fruit is on the way"). So the sight of a colorful bouquet in the morning, they theorize, can convince you that everything's coming up roses today.

, women who saw flowers when they woke up reported feeling happier (and less anxious) at home, as well as more energetic at work
