How can weather affect our health?
Under our mother earth, we are surrounded by a thin layer of gases called the atmosphere. The layer becomes thinner as we go up from the earths surface. Due to emission of gases into the atmosphere another layer called the ozone has also been formed. It prevents penetration of harmful ultraviolet rays from the sun and holds the heat and water molecules from the earths surfaces which are a result of respiration and transpiration of human beings and plants respectively. These contents tamper with the natural atmosphere and affect the weather conditions. Here are some sample beliefs and details about how can weather affect our health.
1. Change in weather can make joints stiff or achy
The first on our list of facts on how can weather affect our health is related to stiff or achy joints. Since muscles and joints have different densities, they both expand and contract to different levels depending on the existing weather conditions. The expansion and contraction process causes pain to muscles and joints and its even worse in framed joints.
2. Rapidly changing temperature can affect immune system
During winter, the body lacks sunlight. This affects the production of cutaneous victim D, which prevents rickets infection. Children and aged with lower levels of vitamin D are at higher risks when infected. White blood cells are also weakened making the body be prone to infections.
3.The solar ultraviolet radiations have a number of effects on human health
Excess exposure to suns rays causes dermatitis which is the skin cancer and also damages the smooth texture of the skin by causing sunburns especially to light skinned people with little levels of melanin. These radiations also affect the eye by damaging the cornea and can lead to cancer of the cornea.
4. Certain weather conditions affect the normal body conditions
Sometimes different weather conditions can cause increased pain to certain body parts causing headaches, cold and simply feeling unwell. This clearly shows there’s a connection between weather and human health. Extreme colds makes the nerves become inactive and numb by tampering with the neurons which detect any action on the skin. For instance it detects burn, touch, pain and sends the message to the brain to direct the body on the next step of action.
5. Our bodies are very sensitive to environmental changes
During cold seasons, the blood vessels around the skin surface contract all round the body periphery. This reduces the sizes of the blood vessels making the heart increase its pressure to be able to pump blood through the narrow vessels. It even can cause high blood pressure levels especially to weak hearts.
6. Rapid weather changes causes irritation to nerve endings which cause pain
At high temperatures, there is increased pressure within the atmosphere while at lower temperatures the pressure levels drop. Drop in pressure can lead to air expansion in isolated body cavities and within fluid membranes. The air in injured tissues tends to create a force on the injured parts due to reduced pressure levels within the atmosphere. This pressure on injured tissues in muscles and joints causes pain.
7. Bad weather conditions increase the mortality rate
When its cold, the air is dense with more water particles which makes it be humid. At this state, the sweat poles on the skin are not in a position to perspire. When unwanted salts and mineral salts are excreted through the skin in form of sweat, the body is in a position to cool itself as the sweat evaporates. Cold weather posse danger to children and aged people as there bodies do not remove all salts and there accumulation can cause death. In this climate, they are also in danger as they are more prone to diseases. In extreme hot weather, plants shed there leaves to avoid transpiration. Grass also dry up leaving bear soil. The air temperatures rise to very high degrees and wind blows over very long distances without meeting wind breakers. The air has a lot of pressure and generates heat winds which cause death to humans increasing the death mortality rates.
8. Cold weather conditions can increase the rate of infection to humans
During cold seasons, people spend much time indoors sleeping, drinking liquor or watching movies. They also tend to spend time in clouded areas like clubs where the temperatures are higher due to body heat dissipation. This exposes them to dangers like infection of tuberculosis in case an infected person is within there midst.
These are some of the ways on how can weather affect our health. So, as you can see, there’s more to weather than meets the eye.
