#spring fatigue syndrome, #chronic fatigue, #fatigue, #spring fatigue, #sleep disorder, #fatigue recovery, #vitamins, #protein, #lifestyle habits, #low energy, #lethargy, #persistent tiredness

Spring fatigue syndrome is a condition marked by a combination of fatigue, sleepiness, reduced appetite, and difficulty concentrating during the spring season. It occurs as the body temporarily adjusts to the increasing daylight hours of the season. It usually improves on its own within a few weeks and can be managed with exercise, a regular routine, and a balanced diet. However, fatigue that persists regardless of season may have a different cause, so please consult a medical specialist in that case.

Stroke

#stroke, #dementia, #vascular dementia, #high blood pressure, #snoring, #weakness in the arms or legs, #difficulty moving one side of the body

Stroke is a medical emergency that occurs when a blood vessel in the brain becomes blocked or ruptures. A blocked blood vessel is called a cerebral infarction, and a ruptured one is called a cerebral hemorrhage. If symptoms appear, going to the emergency room immediately is the most important way to reduce aftereffects. Stroke is also closely related to dementia. The main symptom of stroke is the loss of a specific bodily function, such as paralysis of the arms or legs. The most important factor in treatment is the golden time (the critical time window for treatment), so please be sure to consult a medical specialist for an accurate diagnosis. If abnormal symptoms appear, call 119 (Korea's emergency number) or go to the emergency room immediately.

The lungs are organs that play a central role in breathing. They are responsible for external respiration — delivering oxygen from the air into the blood and expelling carbon dioxide produced by the body. There is one lung on each side of the heart, and each lung is made up of roughly 500 million alveoli (tiny air sacs).

Sugar Intake and Health

#Sugar, #Table sugar, #Blood sugar, #Obesity, #Carbohydrates, #Simple sugars, #Diabetes prevention, #Diet

Simple sugars, such as table sugar, need little digestion and are absorbed into the bloodstream quickly, which can cause blood sugar to rise sharply. Excessive intake raises the risk of obesity and metabolic disease. The World Health Organization (WHO) recommends limiting free sugars to less than 10% of daily energy intake and suggests a further reduction to less than 5% for additional health benefits. Free sugars include added sugars and sugars naturally present in honey, syrups, and fruit juices.

Thyroid Cancer

Thyroid cancer is cancer that develops in the butterfly-shaped thyroid gland at the front of the neck. Prognosis varies greatly by type; papillary carcinoma, which accounts for more than 90% of thyroid cancers in Korea, grows slowly and responds well to treatment, so its outlook is relatively favorable. However, some rarer types have a poorer prognosis, so please be sure to decide on an accurate diagnosis and treatment through a medical specialist.
