Excess sun and heat can lead to the development of many serious diseases. In heat, the risk of overheating and sunstroke increases dramatically. High temperatures can also lead to blood clots, asthma attacks, liver disease, and even cancers of the skin and eyes. Check the he alth effects of heat and excess sun.

Too much sun and heatcan lead to the development of many serious diseases. In summer, the body overheats and sunstroke most often, but severe bone marrow and liver diseases can also be a consequence of an overdose of sun.

High temperatures are also unfavorable for people struggling with heart and respiratory diseases.

Negative effects of heatand excess sun can also affect obese people (due to poor heat conduction through adipose tissue) and diabetics (due to the binding of sugar molecules with water preventing sweating).

The harmful effects of the suncan also be felt by people suffering from hyperthyroidism, due to the rapid metabolism and production of more heat.

Heat and overheating (hyperthermia)

Overheating of the body (hyperthermia), i.e. an increase in body temperature above normal, can lead to heat stroke, therefore a person with hyperthermia requires first aid. Overheating is manifested by weakness, headaches and dizziness, increased thirst, nausea and even vomiting.

Accompanying symptoms may be muscle spasms, especially in the abdomen and legs (due to electrolyte disturbances). With severe overheating, respiratory disturbances, loss of consciousness and convulsions may occur. How to avoid overheating of the body?

Do not stay in the sun for too long. In addition, you should drink plenty of water and avoid caffeine and alcohol. You may also find it helpful to moisten your head and neck with cool compresses. In addition, you should protect your head from the sun with a hat.

Heat and heatstroke

The consequence of overheating the body may be heat stroke, which is manifested by high body temperature, most often exceeding 39 degrees C. However, interestingly, the skin does not show traces of sweat, which are characteristic of fever.

In addition, the appearance of the skin changes - it becomes dry, hot andflushed. A characteristic symptom is the acceleration of the heart rate. Consciousness disorders are also possible. The same rules apply for heat stroke as for overheating.

Heat and dehydration

Heat can also lead to dehydration, i.e. loss of water and electrolytes by the body. During the heat, the body loses water along with sweat.

Then it can lose more than 10 liters of water. It is worth knowing that the risk of dehydration of the body is greatest, among others in the elderly and children. To prevent dehydration, the most important thing is to drink enough fluid.

Heat and heart disease

For people who struggle with heart disease and cardiovascular disorders, summer is the most dangerous season of the year. In hot weather, the body quickly loses water, and the heat causes the blood vessels to dilate, which lowers blood pressure.

In people with low blood pressure, this can lead to fainting and fainting. In hot weather, the risk of blood clots also increases. When the body loses fluid quickly and is not replenished as it is, the blood becomes thicker. It may also lead to the aggravation of the symptoms of people with coronary artery disease, as well as to the deterioration of the condition of patients struggling with leg varicose veins.

Heat and respiratory diseases

High temperature is especially dangerous also for people suffering from chronic respiratory diseases.

Heat can aggravate the symptoms of chronic obstructive pulmonary disease and asthma, as they dry out the mucosa of the respiratory tract. And it reacts more often and faster to irritating factors. Then the symptoms of the disease may worsen.

In summer, too rapid cooling down of the body contributes to the development of respiratory diseases. It can not only cause a cold, but also lead to the development of tonsillitis and sinusitis.

Important

Heat and medications taken

The heat adversely affects people using some sedatives, sleeping pills, antihistamines or antidepressants, as well as patients with parkinsonism. In summer, photoallergic cosmetics (especially perfumes) are also dangerous.

Heat and kidney disease

In hot weather, the body loses large amounts of water. In order to recover at least some of it, urine is concentrated, which is a threat to people withkidney stones. Then, kidney stones may develop. Therefore, keep your body hydrated in hot weather.

Heat and skin diseases

Excess sun may contribute to the formation of precancerous lesions such as actinic keratosis. Lying in full sun later in life can also end up with various types of skin cancer: squamous cell carcinoma, lymphoma, or melanoma.

People with fair complexion and a large number of birthmarks are particularly vulnerable to the latter neoplasm. If any of them suddenly changes shape and color (becomes dark or very dark), and its edges become uneven, jagged, you should see a dermatologist as soon as possible.

To protect your skin from the sun and skin diseases, apply sunscreen to your skin about 30 minutes before leaving the house, and wear hats or caps. Most importantly, however, avoid direct sunlight between 11.00 a.m. and 4 p.m.

Heat and eye melanoma

Excess sun can also contribute to the development of eye melanoma - the most common malignant tumor of the organ of vision. People with a bright (usually blue) iris are especially exposed to it.

Excessive UVA and UVB radiation can lead to melanoma of the iris, ciliary body and choroid, usually manifested by defects in the visual field and the presence of "light balls" wandering across the field of vision, especially at dusk. To protect yourself from this cancer, wear glasses with UV filters.
