Hard to believe, but if you can stand it, a cold shower improves circulation, strengthens the skin (Paul Newman credited cold showers for keeping his skin looking great in old age), and most importantly, boosts the immune system. An added advantage: a cold shower increases the body's production of glutathione, an antioxidant that you can buy in pill form at a health food store for about $40, or get for free in the shower stall.
3. Spice up your life. Not with sex, though you can do that, too, but with actual spices. Long used as medicine, herbs and spices are nature's vitamin and supplements, except they taste a great deal better and cost a great deal less. For example lemongrass, used in Asian cuisine, is a potent antibacterial containing geranial, a powerful antimicrobial agent. Pepper promotes good health and is rich in vitamins and carotenoids. Studies have shown that cinnamon has natural antibacterial properties and is an effective antibiotic against certain dangerous Streptococcus strains. Turmeric is a natural antiseptic and antibacterial agent—and is even a natural pain killer as well. And wash your food down with green tea, which is packed with antioxidants called catechin polyphenols. Some new studies show that all tea, green, black, or red, are equally good for you.
4. Nap. Sounds too good to be true, right? The fact is, most of us have the wrong idea about sleep—we think we're supposed to get 7½ to 8 hours a night. Actually, we're supposed to get that much in the course of a 24-hour period. Humans have always been polyphasic sleepers, meaning we get our sleep in multiple doses. Are You Really Too Tired For Sex?
So don't stress out if your partner keeps waking you up snoring or coughing. Take a nap during the day—if you have the kind of job that allows you to do so. If you don’t, tell your boss that a multitude of recent studies show that workers who nap during the day are far more productive than those who don’t nap.
