People whose sleep is frequently disrupted may experience the same issue. As a result, chronic sleep deprivation has been related to various cardiac problems, including hypertension, high cholesterol, heart attack, obesity, diabetes, and stroke.

Furthermore, 75% of people with depression have trouble sleeping or staying asleep. Sleep deprivation caused by another medical condition or personal issues might exacerbate depression.

Lower Risk Of Weight Gain

Sleep deprivation has been linked to unfavorable metabolic alterations, according to research. Sleeping four hours a night versus ten hours a night increases hunger and appetite in adults, particularly for calorie-dense, high-carbohydrate foods. 

One hypothesis is that sleep length influences the chemicals ghrelin and leptin, which regulate hunger. Another issue could be that lack of sleep causes weariness, which leads to reduced physical activity.

Improves Your Immune System 

The immune system needs sleep to function correctly. Getting enough sleep allows for a well-balanced immune defense that includes robust innate and adaptive immunity, an efficient vaccine response, and less severe allergy reactions. On the other hand, serious sleeping issues, such as insomnia, sleep apnea, and circadian rhythm disturbance, can wreak havoc on the immune system's ability to operate correctly.

Increased Athletic Performance

More or longer sleep has been shown to enhance athletes' recovery and performance. Athletes should get between 7 and 9 hours of sleep per night. Elite athletes are encouraged to get at least nine hours of sleep per night and to prioritize sleep above physical training and food. Before activities such as going to contests, before a major competition, and during times of illness or injury, more rest is recommended.

Sleep is necessary for good health. While considerable resources have been invested in individual and population-level interventions to address health-related lifestyle factors such as nutrition, exercise, and smoking, sleep-related programs have been absent. 

Increased sleep awareness, improved sleep disorders screening, improved sleep conditions for inpatients and residents of long-term care facilities, improved sleep health through public health and workplace interventions, and expanded sleep health research are all needed to promote public health and Safety.
