How Sleep Affects Your Physical and Mental Health

Sleep plays a vital role in both physical and mental well-being. During sleep, the body repairs tissues, strengthens the immune system, and balances hormones. Lack of quality sleep can lead to fatigue, weakened immunity, weight gain, and increased risk of chronic illnesses like heart disease and diabetes. Mentally, poor sleep affects concentration, mood, and memory, and can increase anxiety and depression. Prioritizing 7–9 hours of restful sleep each night supports emotional balance, sharp thinking, and a healthier body. Simply put, sleep is not a luxury—it’s a necessity for overall health.
