Energy levels, attention to detail and creative abilities change throughout each day.  Based on your normal daily rhythms, here are some of the best times to accomplish certain activities:<?xml:namespace prefix = o /> 
7 a.m. to 9 a.m. -- Best for Passion -- The best time to bond with your spouse is right when you wake up because that's when levels of oxytocin (the "love hormone") are the highest.9 a.m. to 11 a.m. -- Best for Creativity -- During the mid-morning, the stress hormone cortisol surges in your brain, which can actually help your mind focus. Because you're primed for learning, take on tasks that require analysis and concentration.11 a.m. to 2 p.m. -- Best for Tough Tasks -- Because your sleep hormone melatonin dips around this time, you're more ready to take on a load of projects. You should be enjoying a surge of energy.2 p.m. to 3 p.m. -- Best for a Break -- To digest your lunch, your body draws blood away from your brain to your stomach. Aim to eat lunch close to 2 p.m. as the midday meal can knock you out.3 p.m. to 6 p.m. -- Best for Cooperation -- The brain is pretty fatigued by now, but that doesn't mean you're stressed. Use this easygoing, low-pressure feeling to your advantage when working with others.6 p.m. to 8 p.m. -- Best for Personal Tasks -- Between these hours, the chances of getting tired are almost zero, so walk the dog, go to the grocery store or goof of with the kids.8 p.m. to 10 p.m. -- Best for Relaxing -- Your energy will fade fast, so prepare to unwind by watching a funny movie or a low-key, repetitive activity, like playing cards.
10 p.m. onward -- Best for Snoozing -- Your brain will try to make sense of all it learned today. Do what you have to do to get your ZZZs.
