Biohacking is a global trend that seeks to optimize the body and mind through small changes in habits, technology, and, in some cases, biology. It involves hacking one’s own body to achieve better physical, mental, or emotional performance, whether through diet, sleep, meditation, exercise, the use of wearables, supplements, or even more advanced techniques such as gene editing and technological implants.
Biohackers can range from individuals who adopt self-care routines and wellness practices (such as monitoring their diet, intermittent fasting, or measuring their sleep with a smartwatch) to those who experiment with synthetic biology or neurotechnology to enhance their abilities.

Optimize your sleep with biohacking
We spend approximately 30% of our lives sleeping, but irregular schedules and suboptimal environments still impact our sleep. The Galaxy Watch 8 series optimizes sleep by analyzing your patterns and environment, identifying issues, and offering practical tips to help you develop regular and restful sleep habits.
• How can I stick to a regular sleep schedule?
Wear the Galaxy Watch 8 for three nights and unlock the Bedtime Guide feature. It analyzes your sleep patterns and recommends the best times to wind down based on your sleep pressure and circadian rhythm, helping you reset your sleep schedule and maximize your alertness during the day.
- How can I improve my sleep quality?
Galaxy Watch8 records every movement and every breath throughout the night. Every morning, you get a detailed sleep analysis based on your sleep stages, heart rate, skin temperature, and oxygen levels, highlighting what helped or hindered your rest. You can also access a sleep environment report that leverages data from your other SmartThings devices to analyze room temperature, humidity, carbon dioxide, and light levels. With this data at your fingertips, you can easily optimize your bedroom conditions for a better night’s rest.

Optimize your workouts with biohacking
Some people train for marathons. Others just want to feel less stiff after sitting all day. So, how can you achieve your goals without losing motivation and avoiding injuries? The Galaxy Watch 8 series gives you all the answers, while adapting perfectly to your wrist thanks to its elegant design and dynamic lug system.
• How can I set the ideal fitness goal for me?
The Galaxy Watch8’s built-in Bioelectrical Impedance Analysis (BIA) sensor measures your body fat percentage, body water content, and skeletal muscle mass, giving you a complete overview of your body. This information helps you create a personalized training plan and track every step of your progress.
Optimize your nutrition with biohacking
Now that your sleep and activity are under control, move on to everyday habits that support healthy aging. The Galaxy Watch8 series is the first smartwatch to measure antioxidant levels, giving you a real-time view of your cellular health and how every lifestyle choice influences it. Simply hover your thumb over the rear sensor to get instant nutritional insights that previously required lab testing.

• How can I easily track my water intake?
Proper hydration is essential for peak performance, but it is often difficult to monitor. With Samsung Health, you can track your water intake with just a tap and set a daily hydration goal. Galaxy Watch8 will take care of the rest by sending personalized reminders and monitoring trends, allowing you to stay fit effortlessly.
The Galaxy Watch8 series turns biohacking from a buzzword to a habit: personal, convenient, and effortless. Wear it, watch the data roll in, and let better health become second nature.
