Modern men sleep poorly. They know it, accept it, and normalize it as if it were a badge of honor. But science is clear: sleeping 8 hours of quality is neither a luxury nor a weakness — it is the most profitable investment you can make in your health, performance, and longevity. And at El Búho Nocturno, a Spanish family business with over 60 years dressing gentlemen, we know this better than anyone.
What happens in your body when you sleep 8 hours
Sleep is not a passive state. While you sleep, your body works at full capacity on processes impossible to perform awake:
- Muscle and cellular repair: growth hormone is mainly released during deep sleep. Without enough sleep, physical recovery is incomplete.
- Memory consolidation: the brain processes and stores the day’s information during REM sleep. Poor sleep means not learning.
- Hormonal regulation: cortisol (the stress hormone) is regulated during sleep. Lack of sleep triggers cortisol, along with anxiety, appetite, and inflammation.
- Immune system: cytokines, proteins that fight infections and inflammation, are produced during sleep. Poor sleep weakens your defenses.
- Cardiovascular health: blood pressure drops during sleep. Chronic sleep deprivation is directly linked to a higher risk of heart attack and stroke.
How many hours of sleep an adult man needs
| Age | Recommended hours | Note |
|---|---|---|
| 18–25 years | 7–9 hours | Phase of greatest physical recovery |
| 26–64 years | 7–9 hours | The optimal range for adults |
| 65+ years | 7–8 hours | Lighter sleep, but just as necessary |
The key is not just quantity: it is quality. 8 hours of fragmented sleep is not the same as 8 hours of deep, continuous sleep. Body temperature, environment, and sleepwear directly influence that quality.

| Immune system | Strong defenses | Greater susceptibility to diseases |
| Cardiovascular health | Controlled blood pressure | Higher risk of hypertension and heart attack |
| Mental health | Reduced anxiety and depression | Irritability, anxiety, depression |
| Longevity | Reduced chronic inflammation | Accelerated aging |
How to improve sleep quality: practical guide
1. Set a fixed schedule
The body operates on circadian rhythms. Going to bed and waking up at the same time every day — even on weekends — is the most powerful habit to improve sleep quality. Your brain will learn to prepare for sleep automatically.
2. Control the bedroom temperature
The ideal sleeping temperature is between 16°C and 19°C. A bedroom that is too hot is one of the main saboteurs of deep sleep. In summer, a breathable cotton summer pajama helps maintain that optimal temperature.
3. Choose the right sleepwear
Sleepwear directly influences sleep quality. A premium cotton pajama regulates body temperature, absorbs moisture, and does not irritate the skin — three factors that reduce nighttime awakenings. For winter, the Double-Peach flannel keeps warmth without suffocating. For summer, the 100% cotton poplin is unbeatable.
4. Limit screens before sleeping
The blue light from phones and tablets suppresses melatonin, the hormone that induces sleep. Avoid screens at least 30-60 minutes before going to bed. Replace them with reading, meditation, or simply putting on your pajamas and disconnecting.
5. Take care with nighttime eating
Avoid heavy meals, alcohol, and caffeine in the 4-6 hours before sleep. Although alcohol initially induces drowsiness, it fragments REM sleep and reduces its quality. A light dinner and a regular schedule are your best allies.
6. Regular exercise — but not right before bed
Regular physical exercise significantly improves sleep quality. However, intense exercise in the 2-3 hours before sleep can make it harder to fall asleep due to increased adrenaline and body temperature. Morning or afternoon are the ideal times.
The role of pajamas in sleep quality
This is no minor detail. Several studies have shown that sleepwear influences body temperature during sleep, and temperature is one of the main regulators of deep sleep. Inappropriate pajamas — too warm, synthetic, or irritating to the skin — can cause nighttime awakenings without you being aware of it.
At El Búho Nocturno, we select each fabric with optimal rest in mind:
- Summer pajamas — lightweight breathable cotton for warm nights
- Mid-season pajamas — classic poplin for spring and autumn
- Flannel pajamas — Double-Peach for the coldest winter
- Velvet pajamas — the ultimate luxury for winter nights
- View the entire collection — sizes S to 5XL, made in Spain and Portugal
Frequently asked questions about men's sleep
How many hours should an adult man sleep?
Between 7 and 9 hours according to the World Health Organization and the National Sleep Foundation. Most adults perform optimally with 8 hours of continuous, quality sleep.
Is it bad to sleep more than 9 hours?
Sleeping more than 9 hours regularly may be a sign of an underlying problem (depression, sleep apnea, hypothyroidism) or simply accumulated sleep debt. If it happens occasionally, it’s not a problem. If chronic, consult your doctor.
What is the best temperature for sleeping?
Between 16°C and 19°C is the optimal range according to most sleep studies. A bedroom that is too hot is one of the main saboteurs of deep sleep.
Does alcohol help you sleep?
No. Alcohol may induce initial drowsiness but fragments REM sleep and significantly reduces rest quality. You fall asleep faster but sleep worse.
What is the best pajama for sleeping well?
A 100% premium cotton pajama suited to the season: lightweight in summer, flannel in winter. The natural fabric regulates temperature and absorbs moisture, reducing nighttime awakenings.
Does exercise improve sleep?
Yes, significantly. Regular exercise improves the quality and depth of sleep. Avoid intense exercise in the 2-3 hours before bedtime to prevent difficulty falling asleep.
