Zoey: Reasons why mobile phone lithium batteries fail in low temperature Temperature is a battery killer! It’s not just heat that can zap out your lithium battery or make it explode. Have you ever had a mobile phone and taken it outside in freezing temperatures, the battery is showing 30% and suddenly your phone dies? The reason for this is because smart phones aren’t built for freezing temperatures and tech giants Apple suggests 32° Fahrenheit as the lowest operating ambient temperature. Other phones are rated for much lower temperatures, and some can go as low as -4° Fahrenheit while in operation. April: Many people, especially from the US and Canada have reported that when their lithium-ion batteries are exposed to cold temperatures, their phone’s performance suffers. When cold, a phone battery can drain faster than normal, or the phone says it has lots of power remaining and then suddenly go dead. Just like you wouldn’t go outside without a coat in freezing temperatures, Make sure that you keep your phone wrapped up. Buy a case or cover for your mobile or electronic device and keep it in your coat pocket or in a bag. This might sound obvious, however, you should never put a spare battery in the fridge or freezer or expose any digital device that has a lithium battery to cold temperatures if you’re in a country with cold temperatures. Stuart: Winter is accompanied by extra risks for injuries and illnesses such as frostbite and hypothermia. There are natural treatments for winter injuries so that if you’re caught with no access to medical treatment, you’ll know what to do to survive. Frostbite Frostbite occurs when your extremities are exposed to cold and the tissue actually begins to freeze. This happens because your body is attempting to maintain its core temperature in order to protect vital organs. To do this, it constricts the vessels so that blood isn’t flowing near the surface where it will be cooled. This means that your extremities aren’t getting the blood flow needed to keep them warm and cells and blood vessels will start to freeze. There are several different stages of frostbite and the higher the stage, the more likely it is that you’ll sustain permanent damage. This is a serious condition that can quickly get out of control so your best option is to avoid it altogether. Margret: Prevention of frostbite is key if you want to keep all of your body parts. That means keeping your entire body covered and warm. Mittens are better than gloves and waterproof clothing is best. Even mild frostbite causes damage to your tissues. Here are the phases, the symptoms that accompany them and how to treat yourself in order to save the extremity, if possible. The most common locations of frostbite are your fingers, toes, ears and nose; keep them covered and warm. If you start to notice tingling or a loss of feeling, do whatever you need to do in order to get them warm again! Zoey: Hypothermia Hypothermia is when your body’s core temperature drops below 95 degrees F. You quite literally start to short-circuit because your brain and your heart are extremely sensitive to drops in body temp. You can’t survive for long if your core body temperature drops by more than a couple of degrees so when you start to notice signs of hypothermia, you need to get warm ASAP. Just like with frostbite, there are a few stages of hypothermia. April: Ready-Heat Disposable Self-Warming Blankets are the only product of its kind to prevent/treat hypothermia，for Military and Civilian casualties worldwide. IN THE FIELD All Ready-Heat Blankets come individually sealed in an oxygen free protective poly-bag. When the bag is opened, the blanket’s heating elements react with oxygen in the atmosphere and generate heat without the need of an external power source. They will maintain their temperature for over 8 hours. Margret: DURING TRANSPORTATION The Ready-Heat First Responder blankets are perfect for  patient transport and emergency rescue. They warm up quickly, over a period of 8-10 minutes, for immediate consistent  warming. After reaching their peak temperature of 100°F/37.8°C they will remain warm for at least 8 hours. TRANSFER The  proprietary panel technology is used for slow, continuous and consistent warming. They heat up gradually over a period of 15-20 minutes and after reaching a peak temperature of 104°F/40°C they will provide sufficient warmth  and comfort for at least 10 hours. The Ready-Heat Panel Blanket line is US Military  Medical  Protocol and approved for fixed wing and rotary aircraft. PRE, INTRA AND POST OP The Temperature Management solution for hospitals. A fully  mobile patient warming device that can move with the patient  from pre-op to intra-op and on to post-op. Stuart: Ready-Heat Temperature Management Blankets are a cost  effective way to keep every patient warm by preventing  anesthesia induced hypothermia, increasing patient comfort  for higher quality of care and are an effective solution for  infection control THERE’S A REASON OUR BLANKETS ARE US MILITARY PROTOCOL—THE TECHNOLOGY Ready-Heat blankets use medical grade non-woven BICO and  specially engineered heating elements to create a controlled,  measured heat over a long period of time, spreading the heat  evenly over the patient.
