Your Safety: Hypothermia
Hypothermia, a condition where body temperatures are lowered followed by rapid and progressive mental and physical collapse, is a year-round threat at Point Reyes. The weather can be highly unpredictable and changes quickly. Even if a summer day begins sunny and warm, cool fog and strong winds can occur later in the day. When you get wet from rain or heavy fog, your body can cool rapidly as moisture evaporates in a breeze. Immersion in cold water can also lead to hypothermia in a relatively short period of time. Water temperatures along the shores of Point Reyes may be as low as 10°C (50°F). Immersion in water that cold can lead to hypothermia in just a few minutes. Older visitors and those with circulatory or cardiovascular diseases are more susceptible to hypothermia. Alcohol can also hasten the onset of hypothermia.
The best defense against hypothermia is to stay dry, stay out of the wind, and avoid getting chilled. Check the weather forecasts. Be prepared by wearing layered clothing. Wear a hat and gloves to conserve vital body heat. Put on rain gear before you get wet. Kayakers, surfers, and swimmers can wear wetsuits or drysuits, and should get out of the water and start warming up at the first warning signs of the onset of hypothermia.
Signs of hypothermia include:
Persistent or violent shivering is a serious warning of the onset of hypothermia. Note that victims of hypothermia often deny that they are cold and often attempt to reassure others that they are "Okay." Hypothermia is often associated with cold weather but can also occur on sunny days at the beach.
First aid for hypothermia is:
Hypothermia can be life threatening! Do not hesitate to ask for help from rangers or call an ambulance.
Did You Know?
Harbor seals (Phoca vitulina) are present in the waters of Point Reyes year round. Every spring, approximately 7,000 harbor seals, or 20% of the mainland California breeding population, haul out on the beaches of Point Reyes. Look for them in the esteros and in Tomales Bay and Bolinas Lagoon. More...
