it Cool in Summertime
During the hot season, keep a cool head: choose exercise activities that
wonít overheat your body. In summer your exercise routine should consist
of swimming, ice-skating, working out in air-conditioned gyms, and
practicing yoga and tai chi. Studies show that the risk of stroke is
three times higher on warmer days than on colder ones. In fact, the peak
months for stroke are June, July, and August. So in summertime make sure
to drink plenty of water and exercise in a cool environment. Donít let
the heat get to your head.
Summer: Later to Bed
Summer is the season of tremendous growth and heat. Heat causes extreme
expansion and promotes dehydration, which destabilizes the nervous
system, lowers production of digestive juices, slows intestinal
movement, and can lead to food poisoning and dysentery. Chinese medicine
says the heart and small intestines are most active during the summer
months. The Yellow Emperorís advice: early to rise and later to bed,
rest during midday, prevent over-heating during physical activities,
drink plenty of fluids, add pungent flavors to the diet, refrain from
anger, and maintain equanimity in order to prevent summer ills.
The Sun: Friend or Foe
Many centenarians understand the power of the sun. They rise at dawn,
and sundown is their bedtime. Sunlight, as we know, can be either
helpful or destructive to our health, depending on our exposure level.
The ultraviolet rays of the sun are a natural sterilizer, killing
bacteria and fungus on the skin as well as promoting the production of
vitamin D, a substance essential for bone health. It can also stimulate
the immune system, raising the levels of natural killer cell activity.
Too much sun exposure, however, can cause skin damage and more serious
conditions such as skin cancer, heat stroke, dehydration, and suppressed
immune function. To maximize benefit from the sun, limit direct exposure
to thirty minutes or less daily, within two hours of sunrise or sunset.
