Cold weather warning: THESE three serious conditions are more likely in winter

While it is possible to suffer a common cold all year round, the condition has become associated with the chilly seasons of autumn and winter.

According to research, it is because the temperature change allows a fresh group of viruses to flourish, and it is these viruses that tend to make people ill.

For example, rhinovirus and coronavirus are two key drivers of the common cold, and are at home in cool weather.

Similarly, the influenza virus spreads more easily when the air is cold and dry.

However, these are not the only illnesses that like to appear around this time of year. 

Here are three that can become more likely when it turns chilly.

Stroke

In autumn and winter, the colder weather can affect your heart.

According to the American Heart Association, people with coronary heart disease often suffer angina pectoris - chest pain or discomfort - when they're in cold weather.

Additionally, according to the British Heart Foundation, cooler temperatures can increase your heart rate and blood pressure, and cause changes to your blood that can increase the risk of developing blood clots and lead to heart attack and stroke.

Seasonal affective disorder (SAD)

It is a type of depression that comes and goes as the seasons change, according to the NHS.

However, it trends to be most apparent and severe during winter.

Symptoms include a persistent low mood, loss of pleasure or interest in normal everyday activities, irritability, feelings of despair, lethargy, sleeping for longer than normal and craving carbohydrates.

It is thought to be triggered by a reduced exposure to sunlight that can affect production of the hormones melatonin and serotonin, and the body's internal clock.

Asthma

While summer weather is known for triggering asthma symptoms, cooler weather can too.

In the autumn, respiratory tract infections - such as the common cold and flu - aggravate the chronic lung inflammation of asthma.

This can lead to coughing, difficulty breathing and asthma attacks.

In winter, cold, dry air can be a trigger.
