A man without sleep experiences significant physical and mental impairments. Sleep deprivation can lead to cognitive decline, including memory issues and impaired decision-making, as well as emotional instability, such as increased irritability and stress. Physically, it can cause fatigue, weakened immune response, and increased risk of chronic conditions like hypertension and diabetes. Prolonged lack of sleep severely impacts overall health and daily functioning, emphasizing the critical need for regular, restorative sleep.
