Unveiling Summer Fatigue: An Insightful Study by FANCL

FANCL, renowned for its personalized supplements, conducted an extensive analysis on summer fatigue using data from over 33,000 individuals aged 20 to 69. This recent survey aimed to explore the correlation between feelings of fatigue during summer and factors like nutrition, sleep quality, and exercise habits. The findings shed light on essential strategies to combat summer fatigue, emphasizing the role of zinc intake alongside adequate sleep and physical activity.

Key Findings of the Study

1. Seasonal Fatigue Perception: Participants reported feeling worse and more fatigued during summer than in other seasons.
2. Nutrient Deficiencies: Levels of essential nutrients, particularly Vitamin B1 and zinc, were notably lower in summer.
3. Fatigue Correlation with Zinc: Individuals who experienced persistent fatigue had significantly lower levels of zinc in their bodies.
4. Sleep Quality Issues: The survey indicated that fewer respondents felt well-rested after sleep or satisfied with their sleep quality during summer.
5. Sleep Duration Matters: Those who slept over six hours reported lower levels of fatigue compared to those who slept less.
6. Exercise Frequency: Regular exercisers (more than twice a week) experienced less fatigue than those who seldom exercised.

These results suggest that combating summer fatigue requires a comprehensive approach focused on nutrition, sleep, and exercise.

FANCL’s Commitment to Health

Since starting in 1994, FANCL has prioritized health and nutrition, adjusting its approach to reflect modern lifestyle challenges.

Detailed Analysis of Findings

The findings regarding summer fatigue also revealed specific health concerns that need addressing:

• - Perception of Health: Survey responses confirmed a higher prevalence of poor health perceptions in summer compared to other times of the year.
• - Nutrient Levels: The analysis highlighted that zinc levels were low in summer, indicating an increased need for this nutrient during hot months influenced by stress from UV radiation and humidity.
• - Rest and Recovery: Summer sleep patterns indicated a need for focus on sleep quality improvements. A majority of respondents expressed dissatisfaction with their restfulness and quality during this season.
• - Exercise and Well-being: A correlation between exercise frequency and fatigue indicates that enhancing physical activity can mitigate feelings of lethargy.

Expert Commentary

Dr. Katsumi Shibata, an expert in dietary guidelines, emphasizes the importance of zinc, especially during summer. He states that the body's demand for zinc rises in hot weather due to increased stress and the need for immune support. When zinc is insufficient, it could lead to energy metabolism issues, causing individuals to feel fatigued. Thus, ensuring adequate zinc intake during summer is vital for maintaining energy and overall well-being.

Recommendations for Summer Health

To prevent summer fatigue, proper sleep and light exercise are crucial, paired with adequate zinc intake from food or supplements. Foods rich in zinc include seafood, red meat, grains, cheese, and eggs. A suggested recipe is the “Gochisou Salad” which incorporates these nutrient-rich foods while remaining appetizing even in hot weather.
