Why do I feel weak and sleepy all over as soon as summer arrives?

Generally, feeling weak and sleepy during summer may be related to high temperatures, lack of sleep, anemia, or other factors, and symptomatic treatment should be carried out under a doctor's guidance. Specific analysis is as follows:

1. High Temperature Weather

During summer, high temperatures and humidity can easily lead to dehydration and fatigue, resulting in generalized weakness. It is important to prevent heat exposure by avoiding prolonged sun exposure, drinking plenty of water, consuming cooling foods, and using umbrellas for shade.

2. Sleep Deprivation

In summer, longer days and shorter nights may lead to late nights or insufficient sleep, which can also cause physical fatigue and weakness. It is recommended to maintain adequate daily sleep and avoid staying up late.

3. Anemia

Anemia occurs due to severe destruction of red blood cells or excessive blood loss. Symptoms may include fatigue, palpitations, and increased sleepiness. Therefore, individuals with anemia may feel particularly drowsy and weak during summer. Under medical supervision, patients may take supplements such as folic acid tablets or ferrous succinate tablets.

In addition, these symptoms could also be associated with sleep apnea syndrome. It is recommended that individuals engage in appropriate outdoor exercises during summer, such as morning jogging, walking, or swimming, to enhance physical resistance and immunity.
