More effort in cold weather
When temperatures are very cold and exercise is performed, the body spends a lot more energy because it also needs to warm up. The heart beats faster to allow the body temperature to maintain itself. When mercury plummets by 1 degree C, the risk of myocardial infarction increases by 2% in the next 4 weeks, especially the first 2. In case of heart problems, it is therefore advisable to focus on an indoor activity.
Cycling, the temperature is always lower, and the wind can be icy. Gloves, hat, neck warmers and mufflers are required. The cold also promotes muscle injury, the blood vessels contract under the effect of cold, a mechanism that prevents heat loss, but it also increases the risk of injury to the effort because the muscles are less well irrigated. It is therefore absolutely necessary to warm up before starting.
If it’s cold, breathe through your nose and exhale through your mouth. The nose warms the air before it enters the bronchi, reducing cold bronchoconstriction, and it can also act as a filter, as pollution is often more important when temperatures drop. Also, it avoids irritation of the mucous membranes.
The importance of hydration
Gloves, hat, technical clothing: the equipment is essential. Care must be taken that the ends are well protected. In fact, we must remember that we lose up to 30% of our heat by the head. For the body, it takes three layers: the first glued to the skin absorbs moisture, the second retains heat, and the third is waterproof.
But in case of severe cold, we must also be wary of dehydration which is bad for the heart. “The cold is also a source of dehydration, which reduces the fluidity of blood and requires more effort to the heart to function,”. So do not forget to hydrate yourself in cold weather, because the feeling of thirst often decreases, but our water needs are just as important.
Any unusual pain or sensation should be an alarm signal to stop the effort. We forget the too violent efforts in cold weather, the ideal for this is to focus on the gym and indoor sports. Especially if you are an occasional sportsman and over 40 years old.
