Individuals with certain health conditions should exercise caution when considering a seaside vacation, especially during peak summer months. A therapist warns that factors like extreme temperatures, high solar activity, and acclimatization can exacerbate existing health issues.

Those with cancer, acute illnesses, or exacerbations of chronic conditions should avoid sea travel. According to the therapist, patients with oncological pathologies should not receive additional ultraviolet and thermal radiation, as this can provoke exacerbation. Acute illnesses are an absolute contraindication until relief.

Conditions that may be worsened by a trip to the sea include diseases of the ear, throat, and nose, particularly those involving purulent processes. Blood diseases, including blood cancers and iron deficiency, also pose risks.

Individuals with hypertension should be cautious, especially during the hottest months. The combination of heat, magnetic storms, and acclimatization can increase the risk of thrombosis, strokes, and heart attacks. Maintaining proper hydration is crucial.

Skin conditions like eczema, psoriasis, and atopic dermatitis can worsen with sea travel, especially when swimming in seawater. However, during remission or recovery, a trip to the sea may be beneficial.

Asthmatics should avoid humid coastal areas during acute stages of the disease. Drier climates like Crimea may be more suitable outside of exacerbation periods. Chronic obstructive pulmonary disease is also a contraindication.

Gastrointestinal issues, such as peptic ulcer disease, can be aggravated by sea travel. Toxic infections are also a risk. Exacerbations of chronic kidney diseases and urinary system problems also warrant postponing a seaside vacation.

Cardiovascular patients face increased risks in hot weather due to dehydration and blood thickening. Strict adherence to a water-salt regime is essential to prevent blood clot formation, heart attack, and stroke.

Pregnant women should carefully plan sea vacations, avoiding travel in the first trimester. The optimal time for travel is between the 14th and 23rd weeks, provided the pregnancy is progressing normally. Parents of babies under three years old should also exercise caution due to underdeveloped thermoregulation mechanisms.

Consulting with a doctor is essential before planning a sea vacation, especially for individuals with pre-existing health conditions. A healthcare professional can provide personalized recommendations regarding timing, destination, and necessary precautions. In mild seasons, sea air can boost immunity and improve lung condition.
