Welcome to Openwaterswimminguk
We have been running open water swimming at various venues for the past 15 years and are the team behind implementing a safe open water swimming environment for other venues to now use and open up there facilities to make open water swimming accessible to all. This has been the desired passion and outcome of the team and the many local clubs, organisations and individuals for many years and open water swimming is really now taking pace as a regular activity to take part in.
There are multiple venues along the Thames valley to try out and train for your next event and if you want us to add your venue to the list of successful venues, please email us and we would be more than happy to get you on board. The furthest lake we have is down in cornwall - Kernow Open Water Swimming.
With the summer in full swing and lots more events taking place, we still have a great summer of events ahead – especially the annual London Triathlon, Rio 2016 Olympics and now Swim Serpentine in September.
Keep up the swimming and the team looks forward to seeing or hearing from you over the summer with your challenges and achievements.
Hypothermia - Human Temperature Threshholds

Through a complex physiological process known as thermoregulation, we humans are able to maintain constant core body temperatures internally despite the many temperature fluctuations in our external environment. However, this is not an absolute phenomenon. Ongoing exposure to extreme temperatures will eventually overwhelm the body’s ability to maintain an ideal body temperature of 37°C (98.6°F). In the case of cold temperatures, this “cascade” roughly follows this process:
37°C (98.6°F) - Normal body temperature, which varies between about 36-37.5°C (96.8-99.5°F)
36°C (96.8°F) - Mild to moderate shivering (it drops this low during sleep). May be a normal body temperature.
35°C (95.0°F) - (Hypothermia) Intense shivering, numbness and bluish/grayness of the skin. There is the possibility of heart irritability.
34°C (93.2°F) - Severe shivering, loss of movement of fingers, blueness and confusion. Some behavioral changes may take place.
33°C (91.4°F) - Moderate to severe confusion, sleepiness, depressed reflexes, progressive loss of shivering, slow heart beat, shallow breathing. Shivering may stop. Subject may be unresponsive to certain stimuli.
32°C (89.6°F) - (Medical emergency) Hallucinations, delirium, complete confusion, extreme sleepiness that is progressively becoming comatose. Shivering is absent (subject may even think they are hot). Reflex may be absent or very slight.
31°C (87.8°F) - Comatose, very rarely conscious. No or slight reflexes. Very shallow breathing and slow heart rate. Possibility of serious heart rhythm problems.
28°C (82.4°F) - Severe heart rhythm disturbances are likely and breathing may stop at any time.
24-26°C (75.2-78.8°F) or less - Death usually occurs due to irregular heart beat or respiratory arrest
