What causes drowsiness during exercise

Fitness drowsiness is usually caused by factors such as increased demand for body repair after exercise, excessive energy consumption, and disrupted sleep patterns. In rare cases, it may be related to pathological problems such as hypoglycemia and anemia. The increased demand for body repair after exercise is a common cause of fitness drowsiness. High intensity exercise can cause micro damage to muscle fibers. During sleep, the body secretes growth hormone to promote repair, and this physiological drowsiness usually subsides within 24-48 hours. It is recommended to supplement high-quality protein such as egg white and whey protein after exercising to help accelerate the recovery process. Excessive energy expenditure can also trigger drowsiness reactions. Long term aerobic exercise or strength training can consume a large amount of muscle glycogen, and the central nervous system saves energy by increasing sleep demand. Timely supplementation of complex carbohydrates such as oats and whole wheat bread after exercise can effectively alleviate fatigue induced drowsiness. Dysregulation of sleep schedule may exacerbate post exercise drowsiness. Some fitness enthusiasts choose to exercise at night, which can disrupt their circadian rhythm and cause an imbalance in cortisol and melatonin secretion, leading to daytime fatigue. Adjusting the training time to the afternoon or evening and maintaining a fixed bedtime can help improve this circadian rhythm disorder. In rare cases, hypoglycemia may induce post workout drowsiness. Excessive blood sugar consumption during exercise, if not replenished in a timely manner, may lead to reactive hypoglycemia, manifested as dizziness, cold sweat accompanied by strong drowsiness. This group of people can eat a small amount of low glycemic index foods such as apples and sugar free yogurt before exercise, and supplement 100 milliliters of electrolyte containing drinks every 30 minutes during exercise. Anemic patients are more likely to experience drowsiness during exercise. Insufficient hemoglobin leads to limited oxygen supply to muscles, and the body compensates for the hypoxic state by increasing sleep. Individuals with iron deficiency anemia can increase their intake of red meat and animal liver in moderation, and seek medical attention for ferritin testing if necessary.

Fitness enthusiasts should arrange their exercise intensity and duration reasonably, with high-intensity training no more than 4 times a week, accompanied by 10 minutes of warm-up and stretching each time. Timely replenish water and nutrients after exercise to ensure 7-9 hours of high-quality sleep. If drowsiness persists for more than 72 hours or is accompanied by symptoms such as palpitations and pale complexion, it is recommended to undergo medical examinations such as blood routine and thyroid function. The relationship between daily training volume and sleep quality can be recorded to find the most suitable exercise recovery rhythm for individuals.
