Introduction

Summer fatigue and drowsiness may be caused by physiological factors, or by medical conditions such as heatstroke or upper respiratory tract infections, requiring medication based on the specific condition. High summer temperatures increase the body's energy expenditure to regulate body temperature, which can easily lead to fatigue and weakness—this is considered normal. Besides these common causes, such symptoms might also result from conditions like low blood pressure, anemia, or hypothyroidism.

Summer fatigue and drowsiness may be caused by physiological factors, or by pathological conditions such as heatstroke or upper respiratory tract infections. Medication should be selected based on the specific condition. Detailed analysis is as follows:

I. Physiological Causes

During summer, high temperatures cause the body to expend more energy to regulate body temperature, which can easily lead to fatigue and weakness. This is a normal phenomenon and generally does not require special treatment.

II. Pathological Causes

1. Heatstroke

This occurs when the body cannot effectively dissipate heat in high-temperature environments, leading to elevated body temperature and a series of symptoms such as headache, nausea, vomiting, thirst, and fatigue. Patients may take medications such as Honeysuckle Oral Liquid or Suhe Xiang Pill under medical guidance.

2. Upper Respiratory Tract Infection

Usually associated with bacterial infection, upper respiratory tract infections often cause symptoms like fever and sweating, resulting in fluid loss and dehydration, which in turn leads to fatigue and weakness. Patients may take medications such as Moxifloxacin Hydrochloride Tablets or Azithromycin Tablets as prescribed by a doctor.

In addition to the common causes mentioned above, fatigue could also result from other medical conditions such as hypotension, anemia, or hypothyroidism. If discomfort persists, timely medical consultation and treatment are recommended.

What causes fatigue and weakness in summer, and what should be done about it?

Summer fatigue and weakness may be caused by physiological or pathological factors, and can be treated through general management or medication. It is closely related to high temperature and humidity during summer, leading to loss of body fluids and electrolytes. If not replenished in time, this transient electrolyte imbalance may cause fatigue.
